I’ve mentioned numerous times in my writings on high-performance blenders that rarely do I sell one to a customer who doesn’t purchase it with a primary goal of improving his or her health.  Yes, these machines are well-known for their wide range of uses – ice cream, bread dough, etc. – and I’ll do my best to demonstrate as many of these functions as I possibly can at my roadshows.  However, I’ve yet to start a single demonstration any way but with simple fruits and/or vegetables, showing my audience first-hand the power of the blender to create a juice or smoothie that is not only delicious, but yields as much nutrition as is possible with any given set of ingredients.  How do I do this?  When blending fruits, I always make a point to use every part of them that is good for us.  Obviously, a ripe fruit’s flesh or pulp is going to be healthy.  But with certain fruits, the skin is perhaps its most nutritious part.  With others, it’s the seeds.  A fruit’s stem, core, or pith (the white part just underneath the peel of citrus fruits) might each contain valuable nutrition that, when simply eating these fruits, will be wasted when we discard them – usually without a second thought.  In taking advantage of a high-performance blender’s incredible power and design, though, a fruit’s entire nutritional content can be easily incorporated into delicious juices and smoothies.

In this article on high-performance blenders I reference their ability to break down a fruit or vegetable to what is commonly referred to as the phytonutrient level.  Only at this level are the individual cell walls of fruits ruptured by the blender’s blades.  This action then releases the vast majority of any given fruit’s thousands of phytonutrients – chemical compounds that studies suggest actually improve health in the body when accessed.  Absent the breaking down of these cell walls, though, the vast majority of a fruit’s phytonutrients will be digested completely unutilized. As the aforementioned article relates, only a blender capable of delivering at least 1 horsepower of actual power (as opposed to listed or advertised horsepower) is strong enough to reach the phytonutrient level of one’s ingredients.  Additionally, only a high-performance blender can produce a juice or smoothie that incorporates the entire fruit yet leave no textural trace of skin, seeds, core, etc.  For most of us, it doesn’t matter how good a smoothie tastes if we have to chew tiny particles of fruit seeds before swallowing.

With a goal of maximizing the nutrition in juices and smoothies prepared with a high-performance blender, following are twenty of this country’s most popular fruits that contain skins and/or seeds that are traditionally discarded before ingestion.  Next to each is listed what, if any, nutritional benefits they contain.


Apple: The skins of apples are a good source of vitamin A but are extremely high vitamin C.  As much as 50% of the vitamin C in the fruit can be found in the skin.  The skin also contains fiber, antioxidants, and quercetin, a flavonoid that is purported to have anti-inflammatory properties.  Apple seeds, on the other hand, contain amygdalin, a molecule which produces cyanide once ingested.  Large-scale consumption of blended apple seeds is not recommended.

Apricot:  Apricot skins are good sources of vitamin C and beta-carotene.  Their seeds, though, are similar in properties to apples.

Avocado:  No documented health benefits for avocado skins could be found.  However, the darker-green flesh just underneath the skin contains its highest concentration of antioxidants.  Be sure to scrape the inside of the skin well after peeling.  The avocado seed, or pit, is high in potassium and antioxidants, and is one of the best sources of soluble fiber on Earth.

Banana:  The peel of the banana is edible and is actually high in fiber.  With non-organic bananas, however, the peel is highly susceptible to pesticides and chemical residues.

Blackberry:  Blackberry seeds are good sources of omega-3 oils, protein, fiber, and antioxidants.

Cantaloupe:  The seeds found in cantaloupes are extremely high in protein and are also excellent sources of phosphorus, potassium, vitamins A, B-12, and D, as well as unsaturated fats and digestive enzymes.  Its rind, although very high in fiber and potassium, is also extremely porous, making it susceptible to mold, pesticides, and chemicals.

Cherry:  Cherry pits are similar in chemical makeup to apple seeds.  It is probably best to remove them prior to blending.

Grape:  Grape skins are great for you and contain up to 100 times the concentration of resveratrol as does the grape pulp.  Resveratrol is a phytochemical that has been linked to the inhibition of cancer, heart disease, and even Alzheimer’s.  It is also highly prevalent in the seeds, especially those of globe and muscadine grapes, along with vitamin E, linoleic acid (an essential fatty acid), and other antioxidants.

Honeydew:  The properties of honeydew seeds and rind are almost identical to those of cantaloupe.

Kiwi:  Kiwi seeds have always generally been considered edible.  They are great sources of vitamin E and omega-3 fatty acids.  The skin contains flavonoids and insoluble fiber, but caution should be exercised before ingesting kiwi skin as its hairy texture attracts pesticides.

Lemon:  Lemon peels are edible but non-organic ones are often waxed prior to shipping to protect the fruit from bruising.  Just underneath the peel is the pith which is white in color.  The pith is extremely high in vitamin C and contains vitamin B6 and fiber, too.  Trace amounts of salicylic acid (the main ingredient in aspirin) are found in lemon seeds.

Lime:  The lime is similar to lemon in terms of the nutritive properties of its peel and seeds.

Mango:  Mango peel is rich in phytonutrients but, ironically, is at its most bitter when the fruit is ripest.  Several edible uses for the large pit in the fruit have been discovered, too.  However, none have been found in its raw form.  For this reason it is advisable to discard the pit.

Orange:  Only trace amounts of anti-fungal properties and vitamin B-17, a purported cancer fighter, have been discovered in orange seeds.  There is, however, as much vitamin C in its pith as the rest of the fruit, as well as fiber, pectin, bioflavonoids, and antioxidants.

Peach:  The peach pit contains amygdalin, just as apples do.  It’s probably best to avoid it.  The skin, though, is very nutritious, containing vitamins A and C, as well as antioxidants.

Pear:  There are numerous pear varieties in the United States, the most common of which is the European.  The seeds in this pear are toxic like apple seeds.  The skin is a good source of vitamin C and chlorogenic acid, an important antioxidant.

Pineapple:  The healthiest part of a pineapple is its core which is loaded with bromelain, an enzyme which acts as a natural anti-inflammatory.  Vitamin C, fiber, manganese, and copper can all be found in the core as well.  Pineapple skin is also nutritious, containing vitamin C and bromelain.  Keep in mind its texture, though.  It’s very susceptible to chemicals and pesticides.

Plum:  Plum skins contain fiber, vitamin C, beta-carotene, and antioxidants.  The seed or pit, however, contains the same properties as apple seeds.

Strawberry:  Strawberry “seeds” are actually tiny fruits, themselves, and are fairly good sources of fiber.  If you’ve ever been to a live demonstration of Blendtec or Vitamix machines, you may have heard the demonstrator advocate the green caps of strawberries as being nutritious.  I, however, have yet to find any study or documentation of any sort that backs this claim.  My advice is to cut off the caps before you eat or blend the fruit.

Watermelon:  The watermelon, as a whole, is one of the healthiest fruits on the planet.  Its seeds contain zinc, iron, and fiber, and can be composed of up to 30% protein.  The outer skin is not exceptionally nutritious, but the rind definitely is, containing vitamins A and C, beta-carotene, and lycopene, an especially beneficial phytonutrient that studies suggest may serve as a preventative for certain cancers such as prostate cancer.


As mentioned in specific fruits above, almost all conventionally-grown fruits and vegetables are done so with the application of pesticides and other chemical agents.  Regardless of how nutritious the skin of a fruit may be, these benefits are almost always negated by pesticides if it is ingested unwashed.  This is reason alone to select organically grown produce whenever possible.  Should one wish to take advantage of the nutrition in traditionally-grown fruits, however, it should be considered essential that they be washed thoroughly prior to utilizing.

Also, keep in mind that thick skins and/or dense seeds and pits can also dramatically alter the flavor of recipes typically made with just the more conventional parts of the fruits.  High-performance blenders certainly make the smoothest of smoothies, regardless of the composition of your ingredients.  However, they can do little about flavor.  The most nutritious smoothie in the world won’t benefit you if you can’t drink it because it tastes bad.  This is why the ultimate decision on whether or not to blend the entire fruit is best left to the individual.

  1. Has there been any measurement of the lycopene content of the juice made from whole tomatoes? Lycopenes are one of the strongest free radical scavengers found to reduce risk of some cancers and reduce risk of heart disease and stroke. But it is locked inside the cell walls of the tomato plant. It can be released by cooking tomatoes for 20-40 minutes. But I’m hoping a Vitamix can be documented to break the cellular wall structures of tomatoes to release these lycopene molecules into the juice for consumption. Any insight about this would be great.

  2. This all sounds awesome. I will give the green juice a try. Thanks!

  3. I like to use raw oatmeal.The benefits are obvious plus it adds a nice creaminess. Put it together with your fruits and/or vegetables for a tasty breakfast. Cinnamon is a favorite of mine too. 1/21/17

  4. I had major colon surgery and now I can’t have the little seeds that are a part of raspberries, strawberries etc. for fear of having them get got in diverticula and sending me back to the hospital. I was told that the Blendtec will pulverize seeds so that they can’t get stuck. Will the Vitamix do that too if I leave it on long enough? Which blender/s would be best for this condition?

    • I would say no to either one. I make green smoothies every day in my vitamixes running them for 3 minutes. Besides seeded berries, I also blend flax or chia seeds.
      I still have to use a pick to get partial seeds out of my teeth.

  5. Hi. My dad has cancer and currently uses a g-tube for all feedings. I’ve been blending his daily compleat with high calorie protein powder and once a day I add spinach, green apple, olive oil or kale and romaine with apple or peach and olive oil.

    We have a Vitamix and I blend on high and then low to mix the foam. He hates the foam. Even after it mixes and sets a while the foam is still 1″ high. What is the difference between juicing and blending? What benefits am I achieving by blending the greens on high or is it just the way to purée ingredients? How do I know when it’s blended enough for g-tube safety?

    • Size,
      You can vent the foam off by removing the lid on your vitamix and blending on your lowest setting for a minute or so.

      I’m not sure about other blenders though.

    • It could be your ingredients causing the foam. And a Vitamix is meant to operate on high.
      I make a blender full of green smoothie and don’t have foam.
      I pack it 3/4 full of baby greens then add fruit and flax or chia seeds (for omega 3s instead of oils). Not sure if that is appropriate for your situation. 4/29/18

  6. Hi there

    Hope you can help, I put two orangesxand a handful of strawberries in a blender for about 20″ seconds. The drink is chunky which I like.

    I believe that I’m still getting fibre and all the nutrients etc however my son whose doing a sports degree has said that by blending the fruit it changes the fruit and basically instead of weight loss I’ll put on weight due to increase in sugar. Is he right????


    • bd

      Dustie, this is a bit outside the limits of my expertise. However, it is logical to deduce there is no increase in the sugar content of a piece of fruit due to simply blending it. What can happen via blending is a change in the way and/or speed in which the body processes the nutritional content of fruits and vegetables. This is probably to what he’s referring.

      Personally, I believe the nutritional benefit of two oranges and a handful of strawberries outweighs any negative effects, whether eaten whole or blended. As for the science which may or may not back my claims, that is to be discovered elsewhere on the internet. 🙂

    • A big issue is that by blending fruits, you will consume way more in one sitting than you usually would at one time. Which is more sugar than is good for you, so mixing it up with veg and seeds is always good rather than soley fruit.

    • On tv about lose weight save money show a woman lost 21lb in a month by a juicing diet so u must lose weight

      • So many other factors have to be considered. Way better like someone else said, add greens and seeds to boost nutrition and slow down absorption.

  7. i am blending all the berries, how can I prevent the little pits/seeds from going into my drink, i even bought a small strainer & it still didn’t help. I just don’t like them they get stuck in my teeth & probably hard on your system like popcorn, will they hurt you to ingest?

    • bd

      Gina, berry seeds will be no worse for you in a smoothie than they would be if eaten whole. A condition like diverticulitis might prevent you from ingesting them, but if you had this condition you would almost certainly know this already.

      The key to eliminating small seeds from your smoothies is simply to blend them longer. Because of the extra friction that might be generated in your blender from extended blending durations, I recommend using frozen berries along with other frozen ingredients if possible. This will allow you to blend for longer periods of time while keeping friction to a minimum.

    • Gina – Seriously invest in a vitamix. You will never have that problem with seeds again.

    • buy a Blendtec & use it all. It’s nutritions …especially seeded grapes.

  8. Hey Blender Dude,

    I wanted to share my cool new product with you, the Smoothie Press™! I LOVE smoothies but like many others, hate crunching through the seeds. The Smoothie Press is a travel mug for smoothies that strains out the seeds! It’s awesome. AND, as if that wasn’t enough, it is compatible with the Magic Bullet so you can blend right in it.

    Check it out. It will be available for purchase July, 2105.

    Have a great day~


  9. I eat apricot and apple seeds every single day. The B17 is very good for your body. I eat the bitter almond looking seed located inside the pit when ever I eat a peach or an apricot and I always have a 2lb bag of raw, no gmo, organic apricot seeds on hand since apricots and peaches are so expensive. I eat between 6 and 10 seeds per day as cancer prevention. There is a lot of controversy with the FDA, American Cancer Society, and the American Medical Association on these seeds because they kill cancer cells without harming your white blood cells unlike chemo which damages not only all cells, but your immune system, and can damage important organs in your body. Go to any of these cancer sites and government sites and they’ll say they are poison, and if you think about it long and hard, you’ll figure out why this makes sense. No cancer, no more lucrative patients. Sickening to think about it, but it’s true. Do yourself and your family/friends a favor and watch “A World Without Cancer” on Youtube for free. It’s an hour long and I spent weeks investigating this stuff. I have since changed my diet to complete organic foods and I feel amazing! The apricot seeds have the highest concentration of B-17 and it’s best to consume 10 or less for prevention. I eat 1 or 2 every hour or so each day until I’ve reached my 10. I had a headache the first time I ate one and after that, I never got another. The suggested serving is 3-5 seeds chewed up at a time, but I just do 1 or 2 at a time. I have never gotten sick or had any bad symptoms. The taste is not so good at first, but I’ve gotten used to it and actually enjoy them now. Kind of like black coffee, pork rinds, and beer when you taste for the first time. I also grind apple seeds (6-10) in my fruit smoothies every day. Do your research and quit worrying about the seeds. They will save your life 🙂

    • bd

      I appreciate the contribution to the discussion, Christina. Best of luck to you!

    • Please explain how your seeds can specifically target cancer cells? Which receptors do they bind to? What’s the mechanism? I’d love to know, so I can tell all the leukaemia patients at work that their chemo is a big pharma lie…

    • Christina, thank you so much for your boldness in sharing the truth about B17. Actually they use to use it for cancer cure in hospitals till they were threatened by FDA after chemo use started, threatened not to be covered by insurance if used. I’m 70 and I remember it’s use for cancer, worked better than chemo. In fact the begining of chemo, was the start of loosing so many to cancer. But good news, Trumps putting a man in charge of FDA that will put an end to the lies and deception of FDA, like the Mauphia just padding their pockets and complying with population controll. Ask them why they have the only patent on marijuana when it’s a natural substance and only drugs can be patented for curing. They did that in 1999. When they discovered that the Canabis oil in marijuana helps to cure cancer and shrink tumors. Think about and research that one. A German scientist received the Nobel Prize in 1931, over 80 yeas ago, for his CURE FOR CANCER with ozone oxygen therapy. Ronald Regan went to Germany and was cured of his cancer in a short amount of time. Research the question. I think it’s beet juice and chloriPhil that’s good for oxygen also. There’s alot of good products the FDA has been supressing. I ordered a product for my brain,(concushion)results, it helps prevent altsimers as well. California will not allow it to even be shipped in. So you can’t even have it shipped to you. Nothing dangerous about it, only to FDA it’s a threat to their money pocket, cause it’s so cheep.

  10. Hello, I just got a Blendtec the other day, and I tried to blend pomegranate seeds. I blended them on high for over three minutes, and they were cooked. I put them in the fridge to cool the juice off, but when I tried it, the seeds were still not completely blended. Is there anything I can do to make my juice turn out better? Thanks

    • bd

      SM, assuming you are blending these seeds with liquid of some sort, the only thing that will assist in breaking them down is extended blending. You must have enough liquid in the recipe to enable the blades to have contact with the seeds. If three minutes of blending doesn’t do the job, you are right in allowing the recipe to cool, but then further blending will be necessary once this has occurred.

    • Yes, there is something you can do: throw away your Blendtec and go buy a Vitamix! 😉

      • Hello Nes:
        I have been searching for the answer of blentec vs vitamix for seed
        total liqueficaton. I have diverticular problems with hard seeds & nuts. Based on your statement I will try the vitamix. I will admit that
        after reading close to 1,000 user comments, the nod goes to blentec, for overall satisfaction, but the liquifying comments are almost non-existent for both machines. I did finally call both companies and the
        vitamix “expert” was more sure than the blentec “expert”. Both were very polite. I will only purchase from cosco so returns won’t be painful if I can’t get the total smoothness my gut demands. Thanks for
        your comment.

  11. Hi BD!

    I have been using green powder in place of leafy greens when I run it ir in addition to fresh greens. What are your thoughts and would rotation of the brands used apply?

    Thanks! – sandy

    • bd

      Sandy, superfoods are very popular these days. Unfortunately I don’t know a whole lot about them. Of course, nothing will beat fresh, organic leafy greens, but I would imagine supplements are a good alternative when fresh isn’t available. Another thing I like to do is make frozen greens ice cubes out of fresh greens and water in my blender. I pour the mixture into ice cube trays and store the frozen cubes in freezer bags. This way I always have real greens on hand whenever I run out of fresh. Rotating your greens is a good idea as well. It would stand to reason that rotating supplements would as well but, again, this is not really my area of expertise. Good luck!

  12. Hi BD,
    I just got a high performance blender, and I was checking your list to see if I could (or should) add the orange peel to my mix. You mention the pith, but not the peel. WOuld it be safe to do so?

    • bd

      Gigi, to the best of my knowledge there is nothing harmful in the peel. It contains oils which may or may not be pleasing, flavor-wise. Regardless, you will want to make sure you have washed it thoroughly.

    • Orange zest (grated peel) is used in a number of bread recipes. I use it frequently. I have also found dried orange zest bottled in the spices section of some grocery stores.

  13. Great article. How do you recommend washing the skins of those that have nutritional benefit?

    • bd

      Thanks, DU. If I’m washing a bunch of grapes or several other pieces of fruit at a time, I like to fill my sink with cold water and add a little white or apple cider vinegar to it. Then I just wash thoroughly yet gently using a soft-bristle brush. Drain, then rinse with cool water. There are also some fruit cleaning sprays on the market but I haven’t used any of them in years.

  14. Happy Vitamix owner now for about 5 months! I’m very pleased that I stumbled onto your site through a google search about the safety of blending lemon seeds into my veggie-pineapple smoothie.

    What was super annoying was taking the seeds out of the lemon and wanting to include the pulp in my smoothies.

    So if I understand correctly from reading all these replies, I should not have to worry with taking the seeds out of both lemons and/or watermelons? I like that!

    • bd

      I wouldn’t worry about the seeds of either, JP, especially those of the watermelon. Feel free to share your smoothie recipe, too. It sounds interesting.

  15. B17 and amygdalin are the same compound.

  16. I don’t know about lemon, but, I have read, from several reliable sources, that lime seeds are poisonous; to the point that a small handful of lime seeds can be fatal.

    They did not say if it is accumulative or not; but, it is recommended to avoid them even more stringently than apple seeds.

    • Blenderdude

      Arletta, I have read this before, too, but never from a source that I would consider credible. By all means please feel free to share your sources on the site. Thanks!

  17. On the flipside…

    As a GI who just got out of 8 years army and now developing “love handles” while eating good food and going to college…what veggies can I add into my smoothies to make it palatable?

    I really dislike peppers and cauliflower and spinach. The 3 I’ve tried so far. I also have an onion allergy.

    Don’t get me wrong, I’m gradually losing the extra pudge I’ve put on since leaving in February so that’s a good thing…but I’d rather get more veggies into that blender instead of just fruit.

    Any ideas?

    • Blenderdude

      Kane, this will be a real challenge. 🙂 If you have a dislike for spinach, it will be very difficult recommending anything for you in the “greens” category, as it is one of the mildest ingredients, flavor-wise, to use in my opinion. So, it is basically going to come down to flavor profile for you, and not necessarily intensity. This will largely be a trial and error type experience. I am a fan of avocado, beet, carrot, and cucumber (not necessarily together). Good luck and thanks for your service!

      • I can really taste the “green” in spinach…I don’t know how to describe it lol.

        • I guess you can say I can taste the “earthiness?” Not sure, but it seems pungent to me.

          • As a mom of grown and basically grown kids that would rather die than eat green veggies.
            I can tell you I have put
            1 c baby spinach
            1 c baby kale
            1/2 c blueberries
            1/4 c blackberries
            2 Roma apples
            Ice and water
            They all thought it was a berry smoothie not one complaint as long as they don’t see it go in and it’s not green.
            For that matter as a psyc. Maj. I can’t drink it if its green either lol thank God for blueberries.

            • bd

              You’ve discovered the magic of green smoothies, SM. Congrats and thanks for sharing!

        • A few words I just added to my vocabulary. 🙂

        • Blenderdude

          Spinach definitely has its own unique flavor, but in my experience, when mixed with other ingredients, is easily overpowered. If you wanted to give it another shot, start with as few as 3 or 4 baby spinach leaves in your smoothie. I really think this few leaves in combination with other ingredients will be virtually undetectable. As you acquire a “taste” for it, gradually increase the amount you add. This is a tried and true method I have recommended with the more flavorful greens. No reason it shouldn’t work with spinach, too.

          • kane,
            have you tried to use arugula instead of spinach?
            I liked the taste of it as a green component in a smoothie

        • This is how my drinks right now constitute:

          4 ice cubes
          1 cup milk
          2 bananers (lol)
          1 pear
          1 orange


          I have one mon-fri before school right now. Any veggies I could add to the mix or replace with a veggie would be cool.

          • I do a mix of fruits and veggies and my smoothies are delicious. The vegetable taste you reference I have experienced, but I compensate with other ingredients. I put a lot of stuff in my smoothies, but the pitcher is big so I mix several days at once. I use:

            *Mini-bell pepper
            *Kale or Spinach
            *Mustard Greens
            *Flax seed

            You’ll need a liquid, so I use a juice. It is just whatever I have in my fridge at the time…Cran-Raspberry, Cran-Pomegranate, Tropical Punch….whatever.

            If you mix it and drink it at this point it taste very earthy, but is likely really good for you. I don’t stop there, though.

            *Strawberries – Costco frozen
            *Berry blend – Costco frozen (Blackberries, Raspberries, Blueberries)
            *Pineapple – Costco frozen
            *Mango – Costco frozen
            *Pomegranate – Costco frozen
            An orange
            A lemon or lime
            An apple
            A banana
            1 heaping scoop of Vanilla Muscle Milk
            1 heaping scoop of Chocolate Whey protein

            and then to fill in any potential holes, I add pills

            a B Super Complex
            a B-12 Mega
            a vitamin D
            a vitamin C
            a Glucosomine

            I used to try and squeeze this all into my Vitamix, but it was stressing out the motor, so now I’ll do it in two stages. Vitamin Water Bottles are great for putting smoothies into. I mix the veggies first and divide it evenly between 4 Vitamin Water bottles. Then I mix the fruits and the pills and divide it evenly between the 4 bottles. There is usually a little bit of room left at this point, so I’ll put a little lemon juice in each, close them, and then shake them up to mix the stages.

            My smoothies are DELICIOUS. I have no problems drinking them. I likely put in way too much stuff and probably pee out a ton of vitamins as my body probably can’t completely absorb all of the stuff I put in. At the end of the day, though, my body probably gets all that it needs from the smoothie as it’s passing through my system and then discards the excess.

            I drink 1 bottle a day, so one session with the Vitamix carries me for 4 days.

            With regards to flavor, things I’ve noticed that have a big impact are:

            *Banana – really adds a creaminess to the smoothie, which I really like
            *Protein powders – mutate the smoothie to taste more like I’m drinking a fruity ice cream then a vegetable/fruit smoothie
            *Lemon juice – this stuff is incredible!! While experimenting with different ingredients, I discovered that if I don’t like the flavor I can just add lemon juice and it helps a ton. It can make the difference between throwing out a failed experimental recipe or being able to drink it down without too much trouble. It also helps mask if some of your ingredients are getting old and going bad. I don’t like throwing out expensive vegetables, so I use them until they’re gone and if the flavor is crossing over I just add more lemon juice.

            When your smoothies taste as good as mine do, drinking them is no longer a challenge.

            I know people that like to mix their smoothie fresh everyday. Whether it sits in your fridge as a whole vegetable or a smoothie, it’s still sitting in your fridge until you get to it. I don’t really see the upside to mixing daily. The upside to making several days worth at once, though, is less time cleaning the blender. I am also busy, so finding time every several days to blend seems easier to me than finding time each day. Most days I just reach in the fridge on the way out of the house and grab my pre-made smoothie. It’s so convenient!!

            Hopefully this helps 🙂 Cheers to healthy (and delicious) nutrition!!

            • bd

              Shawn, thanks so much for such a detailed description of your smoothie regiment. The lemon juice trick is one I’ve never used – will definitely give it a try.

          • Hi Kane
            I’m not sure when you wrote this as I don’t see dates. You need to put some fats and protein in your smoothie so it will fill you up. You could put Greek yogurts in, peanut or any nut butter,Chia seeds, flax meal. Those will also help disguise the spinach until you get used to it. There are a lot of green smoothie recipes on pinterest. Good luck!

        • Although, I should probably admit, I get a nice pick-me-up drink with what’s left after school so it’s like 2 servings lol.

        • Do you happen to have a veggie-friendly link? I been looking through tonight and didn’t see anything.

      • Alright, thanks.

        I do my shopping on Mondays when everything’s empty so I’ll try it then. 🙂

      • I Think you would be able to tolerate the spinach and other greens if you don’t taste them. I don’t care for spinach or kale…but I blend 2 thick slices of pineapple, I cup of green grapes and a cup of spinach and kale (1/2 cup each) and a sliver of lemon with 1/2 to 1 cup water…when I have it I add fresh ginger. then I can get both spinach and kale in my diet!

    • First time I’ve read this site, just bought a vitamix and researching recipes.

      I’ve been a juicer for 20 plus years, so the recipes are a bit different; but when juicing greens, no matter how strong the greens were, I always added lemon and apple.

      If the greens taste was too strong, I would juice more lemon, maybe a bit more apple. My goals were to not add too much fruit and focus on the greens. I would say the lemons with a little apple, were always the cure for too “green tasting” juices.

      I’m sure the blender will be very different, but I’m thinking lemons will still be the solution. However, when juicing beets, I always had to use less beets because they were just too strong for my taste and ability to digest.

      One more note, I used to always juice limes or lemons, and never had any trouble, and never heard that lime seeds were deadly. that just sounds weird to me, but I’m no expert.

      Thanks Kane for your service!

      (also, not sure how old this article is, so I apologize if this is really old 🙂

    • Kane,

      I am the mother of a Marine who detests spinach or anything green besides luttuce! I made him a blackberry smoothie and he loved it! I didn’t tell him it had spinach in it until he was finished. He was very much surprised and said he would drink it again.
      1.5 C of Frozen Blackberries
      1 Ripe Banana
      1/4 Low Fat Yogurt or Greek Yogurt
      2 C Fresh Baby Spinach
      1/2 C Canned Pineapple
      1 C Almond Milk
      1 C Ice

      Enjoy! Thank you for your service!

  18. I just got the ninja ultima and I’m really getting into blending I mix fruits and veggies all in it and drink them all day. Is it ok use agave syrup to sweeten the taste. Also I’m kind of just throwing stuff in as I see it.

    • Blenderdude

      Aywa, it is certainly okay to make “impromptu” recipes with ingredients you have on hand. You are going to want to use any sweetener in moderation, including agave. But if that’s what it takes in order to make your smoothie palatable then I would imagine its usually preferable to the alternative. In my experience the fewer ingredients you use the more likely you are to gauge the flavor, thus being able to predict whether or not you’ll have to add sweeteners. The right amount of fruit to greens ratio can result in a perfectly delicious result that calls for no added sweeteners. You’re just going to have to experiment with ingredients you like. But the important thing is to keep using your new blender!

  19. Any guidance for a Pure Vegetarian on What food items would be good source of protein????

    • Blenderdude

      Latha, I’m not a nutritionist but I believe most nuts, beans, and even some leafy greens like spinach are all excellent sources of protein. Both dairy and non-dairy milks are also good sources. And perhaps my favorite smoothie ingredient is chia seed, for its protein as well as a variety of other benefits.

      A good protein powder can also be an option. My favorite sources are hemp, vegetable, and egg-white.

  20. This site is Truly Remarkable. This is one of my favorite site online as of now. Also a question for you. At only 26 i was put on a life long fiber diet due to some internal issues and have yet to find a great recipe for a total protein and fiber smoothy..any ideas??

    • Blenderdude

      Mindy, thanks for the nice compliment on the site. I’m glad you like it. I would imagine most smoothie recipes are good sources of fiber as fruit is full of it. I would also suggest adding nuts and seeds like chia and flax. Nuts are doubly-beneficial because they are high in protein, too. Greens like spinach are also relatively high in protein, so don’t forget to add them, too. Regular milk is a good source of protein and, of course, you have seemingly unlimited choices in protein powders if you wanted to go that route.

  21. I had no idea you could blend an avocado seed and that it would be healthy for you. So when you make guacamole, do you typically blend it with the seed? Btw, blackberry seeds are a good reason why one should have a high powered blender for health. Before I got my Blendtec, I used to avoid blackberries and raspberries because the seeds would always be left intact no matter how long I let them blend. But the Blendtec takes care of them pretty easily.

    • Blenderdude

      Joe, I do not blend the avocado seed when making guacamole. Remember, just because something is potentially good for you does not mean its taste or texture is going to be pleasing to the person eating/drinking it. If you can’t get it down, it really doesn’t matter how good it is for you, right? 🙂

      I would imagine the seed would significantly alter the texture of guacamole, and possibly the taste, too. Good luck to you if you try it. Share with us your results if you do!

      • If you blend the seed and use a spoonful of it in your guac…it will naturally keep it from turning brown.

        • bd

          Have never tried that before, Trina. Thanks for sharing.

          • Blendtec rep told us that avocado pit has strong pine flavor, so use sparingly however you want to use it. Also, if you don’t want to grind up your pit, you can put the whole pit in your guacamole when storing and it will keep leftovers from turning brown

            • bd

              Kris, it’s true the pit has a distinct flavor. It will also alter the texture of your recipe. I’ve tried the trick of putting the pit in the guacamole. It sounds like a good idea, but in actuality might be closer to an “old wives tale.” 🙂

  22. I really enjoyed this article, Blender Dude, and will visit often. I loved all the comments, as well. So much information! I just purchased a Vitamix and am learning the recipes. But I am prone towards diabetes (runs rampant in my family) and high cholesterol and was wondering if you might direct me to some good recipes I can incorporate that will help in lowering blood sugar and cholesterol. All the fruit smoothies scare me a little bit.

    • Blenderdude

      Hillary, thanks for the nice words about the site. I’m neither a doctor nor dietitian, so I’m hesitant to give out advice for specific conditions you might already have, but it is fairly well-documented that greens, superfoods, and certain fruits can help with blood sugar regulation and lowering cholesterol. Instead of avoiding fruit altogether I suggest using it in moderation and focus on those high in fiber and antioxidants – blueberries, as one example. Use plenty of greens – spinach, chard, kale, etc. And do some research on superfoods like acai to see if you think you’d like to incorporate them into your smoothie regiment as well. For specific recipes, I suggest a Google search for “Heart-healthy smoothie recipes” and/or “Smoothie recipes Diabetes.” Good luck to you!

      • Pinterest has so many ideas!
        You eventally want to use just a serving of fruit or low glycemic fruits along with greens and superfoods.
        Good luck!

    • Vitamix? You wont be sorry.
      We have owned three of them over the last 22 years and have raised our brilliant minded healthy children with them.
      I’d like to share with you what 22 years has taught us.
      Blending raw fruits and vegetables can be very pulpy to drink and can turn the stomach of even a sea captain.
      If you blend it on high to long it will begin to cook, depending on what you are trying to achieve that can be good or bad.
      Most people prefer to blend with ice that works pretty well but what we have found that makes the smoothies the most pulp-less is to freeze, freeze, freeze! Yes freeze everything. By doing so you burst the cellular membrane juice pockets releasing more juice and nutrition and also burst the membrane fiber leaving it less pulpy for better absorption.
      Take leafy vegetables after washing and stand them up in a cellophane bag like from a Total cereal box, re-drain after 5 min then put them in your freezer. After frozen crush the bag with your hands and you’ll now have a quarter bag or less of fines to dip into with a measure cup for your smoothy.
      Fruits can be cut into wedges.
      If the smoothy is to veggie in flavor then add IRON RICH raisins or tarten it up with sugar-free cranberry juice. You don’t need to freeze the juice though only if you prefer that.
      Good health and happy juice’en.

      • Blenderdude

        Thanks for the feedback, ic!

      • Yes to everything you said except why not add frozen cranberries to your smoothies instead of the cranberry juice? It’s been proven the whole fruit is much more beneficial than just the juice ~ I had left over cranberries frozen from months ago and decided to use them up, guess what? they’re fabulous!
        Just a thought…

  23. Do you have any info on the safety of blending tomato seeds please?

    • Blenderdude

      Debbie, I don’t know of any blender, especially a high-performance blender, that would have much difficulty blending tomato seeds. If one needed the seeds to be completely pulverized such as those who suffer from conditions like diverticulitis, using a high-performance blender would be the best way to go about this.

      If you are referring to the nutritional content of tomato seeds, I don’t know much about them except for them being fairly high in fiber.

  24. So, I understand then that mixing these seeds are compatible with each other under normal conditions, hopefully, and can work nicely with each other without a problem with chemical unbalance when digested?

    • Blenderdude

      I can only speak to the nutritional properties of them, individually. How they react with one another when combined is a subject far above my pay-grade :-). I’m certain there are much better online resources for this than myself.

  25. Is it okay to mix Pomegranate Seeds with Papaya Seeds and / or Pumpkin Seeds in a Blender for a Health Drink?

    • Blenderdude

      Larry, I believe just about any decent household blender could blend these types of seeds without risk of damaging the blender. Just how well they will be blended is another matter, however.

      If you are asking specifically about the health benefits of these seeds, I haven’t done any extensive research into any of them. I do know, though, that there are many claims out there touting the benefits of all three.

    • I’m an evangelist, minister of health, public speaker, & financial adviser. I’ve studied about health & the Bible for many years. I’m now 70+ years and have learned many secrets & AMAZING MYTHS. I’ve learned that to get the most out of seeds-let them sprout before eating then blend to a liquid with eggs & fruit or whatever nutritious liquid.

  26. I have a Nutribullet and tons of tomatoes this year. How do I make fresh homemade tomato juice with it?

    • Blenderdude

      Rose, you can use just the tomatoes and just enough water to get the consistency you like. If you prefer all the pulp to be removed you can also strain your result through a filtration bag. I also recommend you season your juice. It makes a big difference for me. Good luck.

  27. Great article, but I am very curious about Avacado seed. It says high in pottasium and antioxidants, plus fiber. Well I tried one and its also great business for the Dentist! Just kidding, I glued my teeth back in and ask, how does one eat the Avacado pit? I was thinking maybe I could trap a squirrel and have him crack the pits for me…

    • Blenderdude

      Clark, you are on the right track, but I would recommend you use a raccoon. They are easier to train :-). Actually, if you’re interested in capturing the nutritional benefits of the avocado pit, the best way is probably to blend it in something like a smoothie.

  28. BD,

    I have to ask why red grapes over Black? I prefer the black.


    • Blenderdude

      ESJELM, I don’t believe the article mentions a preference of red over black. Most black grapes I’m familiar with are deep purple, and I would consider red, anyway. Generally, the darker the grape the higher levels of phytochemicals such as Resveretrol it contains. There’s absolutely nothing at all wrong with black grapes.

  29. Good Morning, I accidentally blended two plumbs in my smoothie this morning with their pits in. Is it ok to drink my smoothie, or should I disgard it? Thank you!

    • Blenderdude

      Don’t misconstrue this as medical advice, but it is probably safe to drink your smoothie as a one-time experiment. I wouldn’t make a habit out of blending plum pits, though. Depending upon how well they blended, you may not enjoy them, anyway.

  30. Thank you for the helpful article, but I think that one thing may be incorrect. The entry regarding oranges contained a misleading detail. It said that orange seeds contain “vitamin B-17, a cancer fighter,” but if you look at wikipedia, at http//en.wikipedia.org/wiki/amygdalin, you will find that B-17 is not actually a vitamin, it does not fight cancer, and it breaks down to produce hydrogen cyanide, a potent toxin. It is broken down by beta-glucosidase, an enzyme found in your small intestine and in various common foods. In one study by the US National Institutes of Health, cyanide toxicity was found in several patients taking B-17, which is also called laetrile and is closely related to amygdalin.

    • Blenderdude

      Mark, thanks for your input. There is certainly a lot of ongoing debate regarding B17/laetrile. I have made a slight amendment to my description regarding orange seeds. Hopefully your comment prompts readers to do their own research and draw their own conclusions about whether or not they want to include them in their diets.

  31. Hello, I have been making mint simple syrup for years, And it always experimented with different kinds of seasonal berries. This year I decided to make a citrus blend I took orange peelings grapefruit peelings lemon peelings and lime
    Peelings put them on the food processor with equal parts sugar, let them rest a bit so the sugar and the oils could combine. Then added equal parts water, brought to boil let sit for 30inutes. What I got was a beautiful, orange colored citrus syrup. The left over pulp rind was also very fragrant, pretty and kind of tasty! After reading on the Internet lots of people eat citrus rinds. I decided to freeze the left over pulp for marinades like for orange chicken or any kind of sweet dish. Omg! That might for supper made a sweet onion teryiki steak marinade and it was awesome! You would not believe how much citrus flavor came out of that scoop! Today I food processed just g fruit rinds & sugar to a fine consistincy an made cady. I guess what I want to know is this safe for my fam. I havnt been peeling down the pith or anything because I read it has just as much vit. C as the fruit.
    Thank u & sorry for the long text!

    • Blenderdude

      Brenda, both the pith and the rind on almost all citrus fruits are perfectly edible and nutritious, especially the pith. Make sure to thoroughly wash the fruit prior to using, though, especially if non-organic.

    • Just wanted to reply to Brenda’s post. I’ve juiced for many years, always juicing the whole peeling of citrus. Years ago I read that although all citrus was great for juicing, that grapefruit peeling was a bit different than the other peelings, stating the grapefruit peeling was harder to digest. I believe this to be correct, because I noticed the mornings I used a grapefruit in my morning juice, it seemed different, and not as satisfying. A little was okay, but every morning or the whole grapefruit wasn’t recommended.

      Btw, I really enjoy this site. Thanks.

  32. I apologize in advance if you’ve addressed this previously. I recently purchased a Vitamix. One of the reasons I chose it was so that I could create nutritious smoothies that I could get my picky-eater child to drink. using the Vitamix, when I have used raspberries or blackberries, there still are seeds. At the demo where I purchased this, I was told that smoothies would be smooth, and that seeds would not be detectable.

    Is there a method to create smoothies with berries but without the seeds (can they be liquified?)?


    • Blenderdude

      Ruth, yes, with the Vitamix you can pulverize most seeds to the point where they are virtually undetectable. The quantity of these fruits you use will determine how long you must blend in order to do so. The more fruits containing seeds you’re using, the longer you must blend. You will want to use the High setting for best results (use the lower settings when turning on the blender, then go to High).

      The thing to keep in mind, however, is that the High setting will produce a lot of friction – so much so that it can and will eventually heat your juice/smoothie. To keep this from happening, my recommendation is to freeze the high-seed content fruits prior to blending. This will allow you to blend for a longer duration, enabling you to pulverize seeds, while at the same time keep temperatures low.

      If you find that you must use fresh fruit, use some ice along with it to achieve similar results. In short, the longer you can blend these fruits, the less detectable the seeds will be.

    • I have been told the lemon as a whole is edible and healthy, I’ve read you can freeze the whole lemon to grate on foods. with greater benefits then just the juice and inertia fiber. I was not aware of the wax covering on the skin. Knowing this I would first remove the outside skin. Is this the best way to eat the lemon.


      • Blenderdude

        Robert, grating frozen lemon onto foods sounds like a good idea but I can’t say that I’ve ever tried it. If the lemon is organic I would not have any reservations about using the outer peel. If it’s not, I wouldn’t use it unless I gave it an extremely thorough cleaning, first.

      • One more post I’m going to add to here, 🙂

        After buying a house that two old lemon trees, that produced crazy amounts of lemons, I researched how to preserve them. Trying several difficult and too time-consuming recommendations, I finally just tried freezing them whole in Ziploc freezer bags. It worked perfectly. After washing them, I recommend letting them dry completely before freezing them. I would then thaw them before juicing. I found the taste to be equally refreshing and delicious- perfect.

        Freezing lemons for later use is perfect for cooking. They will not look good for garnish, etc, because the lemon peel will have a mushy appearance. Don’t be fooled though, they still taste great. Through experience, the frozen lemons were good for almost a year, after that the freezer burn took over.

        • Hi Nancy
          I never knew this about lemons and am so glad you posted about it although I don’t know when you posted. I wish there were dates.

  33. Thank you Blender Dude, I was looking for info on what was safe to use and not, I appreciate your research and that you shared!

  34. We have been using the Nutri-Bullet for about 4 months now and love it. We are 62 and 65 yrs. old. Recently went on a trip and were away from home for 4 days. Made up some “smoothies” ahead and stored them in a container and surrounding ice to keep it fresh. My husband has bad cholesterol so his smoothie needs 1/4 C. raw oatmeal in it..The smoothie is very creamy but got very think…add a bit of water and it thinned right out.
    Thank you for this amazing info..fantastic..now I will be “extracting” even healthier

    • Blenderdude

      Diane, thanks for sharing and continued good health to both you and your husband!

  35. I have recently started juicing/blending, this is my first time on your site, I have found the information to be both interesting and enlightening. keep up the good work.

    • Blenderdude

      Barbara, thanks for the encouraging words. Good luck with your blending and juicing regiment.

  36. Is there any harm in blending the strawberry caps? It seems easier to leave them on. Why do you take them off?

    • Blenderdude

      Jessica, to the best of my knowledge there is no harm whatsoever in leaving on the caps when blending strawberries. I would make sure they were thoroughly cleaned like the rest of the fruit. I was not able to find sufficient evidence to suggest that these caps are actually beneficial, but that doesn’t mean they are bad for you. In fact, you will still find plenty of advocates of leaving them on, including many high-performance blender salespersons. 🙂

  37. Drinking a kiwi smoothie has left my lips and tongue feeling like it was poisoned and cut up with tiny shards of glass. The kiwi was peeled, but I left in the seeds. Any suggestions?

    • Blenderdude

      Patty, how awful. I am very sorry for your experience. I have enjoyed numerous kiwi smoothies without experiencing anything like that. It sounds to me almost like an allergic reaction of some sort. I am hesitant to draw any kind of medical conclusions on your behalf – that’s not what I do – but I would look into this possibility. I’m sorry I can’t be of more definitive help to you.

      • Thanks BD. I’ve eaten kiwi whole before without this reaction. I’m just wondering if maybe I needed to let it blend longer so the seeds get fully pulverized. I’ll try that next time and thanks for the quick response.

        • Blenderdude

          I can’t imagine kiwi seeds being the culprit. But this is not really my area of expertise. If you ever figure out the cause, please share with us. Good luck!

          • I have noticed how I eat the kiwi makes a difference. If I slice it open and eat it with a spoon, no problem. If I blend it, the seeds get broken. If I drink the kiwi blended with a straw, not a problem, but if my lips contact the drink with the blended seeds, it burns. I’m guessing there are some enzymes in the seeds that get released by the blender.

      • It’s called oral allergy syndrome. You’re likely allergic to one of the fruits. Kiwis and strawberries do it to me every time.

    • I’ve had this happen too! I’ve eaten kiwis many times before, then only the last 2 times I had a reaction where my tongue, back of my throat and my lips became REALLY itchy while my lip felt swollen. Freaked me out. The first time I thought it was because I’d eaten the skin but the 2nd time I cut if off :S

  38. I have used both the Blendtec and Vitamix blenders. I find that when I blend items the juice, smoothie or soup
    Ends up kind of foamy. I made cream of broccoli soup in my blender and it was too airy feeling compared to using a
    food processor. Can you give me some suggestions on what I might be doing wrong? The soup that was made at a
    demo was not foamy or frothy. ( I got the same thing when just pulverizing tomatoes).

    • Blenderdude

      Susan, a general tip for all recipes is to blend for the shortest duration possible. Once you think you’ve achieved your desired consistency, stop the blender and check it. You can always resume blending if necessary. Some recipes, like soups, require extended blending durations. A tip to removing excess foam is to start the blender once again, this time on the lower settings (Speed 1 on Blendtec, 2 or 3 with Vitamix) you will notice air bubbles on the surface gradually get reincorporated into your recipe. You can continue this process for as long as necessary until an acceptable level of excess air bubbles for you is achieved. Finally, with smoothies, the colder your ingredients, the less prone your recipe will be to become foamy.

  39. Do you get the same amount of “bulk” or fiber from blended fruits and veggies as you would if you just ate them in their whole state?

    • Blenderdude

      Pam, yes, to the best of my knowledge. Assuming you don’t blend to excessively hot temperatures, all the fiber remains. Rate of digestion is the only thing that should change when you blend as opposed to eating whole.

  40. This may sound like a really stupid question, but I would like to know. Is it bad to swallow a lemon seed? I ask because I was at a restaurant with my mom, and I took a sip of my iced tea (which had a lemon slice). For a second I thought I may have swallowd a lemon seed. Like I said, it’s probably a stupid question but I would like to know.

    • Blenderdude

      Lisa, I’m almost certain doing so is completely harmless. Lemon seeds may even have some nutritional value, although I’m not sure to what extent.

  41. Is it ok to freeze the leftover smoothie i make for my one year old for her to eat later? Would that diminish the nutrient content since its not consumed right away? Also, would thawing/microwaving the leftover reduce the nutritional value?

    • Blenderdude

      Jungmi, it is absolutely fine to freeze your leftover smoothie. The only diminishment of nutrients will occur between the time you make the smoothie and the time it freezes, which will be minimal. Even if you lost a little nutritional value in thawing, the smoothie would certainly still be worth consuming. You could always freeze leftover smoothie in ice trays and then put them right back in the blender for your next serving.

      • Thanks for your response! I had another question if you don’t mind. Is it possible to have too many smoothies? We used to drink two or sometimes even three smoothies a day when we first got our blender but we have stopped after I read it might be bad to drink too many. Also, is it bad to use same veggies (kale & spinach) every time? I heard the greens need to be rotated, and if so, any suggestions on what other greens we can use? Thanks so much for your help!

        • Blenderdude

          Jungmi, keep in mind with my answers that I am not a nutritionist. I don’t know that it’s possible to ingest “too many” smoothies, but there is a school of thought out there that suggests you not always use the same leafy greens over and over again for your green smoothies. Naturally occurring alkaloids in some leafy greens, when ingested in large amounts, could lead to mild side effects. The alkaloids in each green are different, though, so rotating your greens is generally considered to be all it takes to avoid this possibility.

          There is also a school of thought that says stick to one leafy green per smoothie (in other words, don’t use spinach and kale at the same time), but I’m not that well-versed on the reasons why so I’d rather not give advice in that regard. Personally, I’ll buy a bunch of kale and use it until its gone, then buy a container of spinach and do the same thing. I also rotate chard and, if I can find them, dandelion greens into my smoothie regiment. So, every 5 to 7 green smoothies I’ll introduce a new green. I do this more for variety than for any other reason, but I’ve never experienced any of the effects alkaloid poisoning is said to induce.

  42. Hi. I read down to where you were replying to someone about the lycopene in watermelon and you weren’t aware of it’s abilities in helping weight loss. I’d like to refer you to Dr. William Li’s Ted talk on “Can we Eat to Starve Cancer?”


    His work is with angiogenesis, and he’s been looking at foods that have angiogenic inhibitor properties. Lycopene was one of the key nutrients for angiogenic inhibition which fights back the out of whack blood supply that our body starts to feed cancer tumors. Turns out our fat cells rely on angiogenic factors to get their blood supply, too. So anything with lycopene would inhibit the blood supply to fat cells.

    I’d recommend visiting http://www.eattodefeat.org/foodlist and using their full food list and it’s clickable database of information to see which foods have anti-angiogenic properties for fighting cancer AND out of whack fat cells.

  43. I’ve been juicing for years now and have always adhered to the “rule” to not blend fruits (other than apples) and vegetable together. I recently purchased the nutribullet (saves about 1/2 hour each morning) and all their recipies combine fruits and vegetables. I like to throw a handful of blueberries in with my spinach, celery, parsley, ginger, carrot and beets but do not want to loose nutritional value. I understand the different enzymes needed for digestion of the two can cause a decrease in absorbed nutrition. Would greatly appreciate your feedback.

    • Blenderdude

      Jim, all I can tell you with certainty is that I am far from an authority on the ever-present food combining controversy. I’m familiar with the science that states that the digestion of different foods requires different enzymes, and I’ve read what appears to be credible testimony that absorption rate can be influenced when combining fruits and veggies, but I don’t think I’ve ever read anything that actually proves a decrease in effective nutrient absorption when different enzymes are being utilized simultaneously.

      There’s another school of thought that suggests not to combine because of potential fermentation issues resulting from the starches in veggies and the sugars in fruits, although, again, the ramifications have more to do with digestive discomfort rather than actual nutrition loss. And even in these instances, leafy greens are generally excluded from the “do not combine” lists.

      In practice I usually juice my veggies and blend my fruits (with leafy greens) and, simply for taste’s sake, keep them separate. I think it’s also important to keep in mind that everybody has his or her own unique digestive system, so even the more credible evidence in this debate won’t necessarily apply to everyone. “Listen to your body” is the best advice I can give. I’m sorry I can’t offer you a more informed response.

  44. Man, you’re really knowledgeable about this stuff. I love your passion. …You’re cute, too.

  45. I undergo chemotheraphy right now and i drink carrot and apple juice but i get confused as i read your article because someone told me to peel off all the fruits before eating or juicing. But as you said the healthiest part of the apple is its skin, so is it safe for me to include now the skin of the apple? Thanks!

    • Blenderdude

      Gen, first, I wish you the best with your treatment. My assumption is that whoever recommended you peel your apples first is concerned with pesticides or non-natural fertilizers that were used to grow them, and this is a legitimate concern. He or she may also be aware of a common practice performed on smooth-skinned fruits and vegetables sold in grocery stores involving them being coated with wax which helps prevent bruising and maintain firmness during transportation. This, of course, helps improve the fruit’s appearance on the store shelves, but is certainly not healthy for you to ingest.

      As for apples, although the USDA claims this wax is “safe” they also recommend you wash it off prior to eating them which might seem to be a bit of a contradiction. Apple skins of organic and non-organic varieties are definitely nutritious, but you first have to get rid of anything toxic that has found its way to them. If you want to eat the skin/peel of any fruit, especially if it’s non-organic, wash/scrub it thoroughly, first.

  46. Hey,

    I really appreciate this info! Some I already knew, but you helped clarify several points!!

    I am curious about Pomegranate. I wonder about the white and the skin of that? I am thinking that it might be similar to an orange. What do you think?


    • Blenderdude

      Lisa, the pomegranate pith/rind is very bitter but actually does contain large amounts of antioxidants. Also, the seeds are rich in protein. If you can handle the taste and texture, both can be beneficial.

  47. Hello. Loved this write up. Would you consider doing one for vegetables too? For instance, if I’m making soups what seeds or stems should I keep, which ones should I toss? Or have you and I don’t see it?

    • Blenderdude

      Shala, I have not written one but if I can find enough information on veggies I just might. Thanks for the idea.

  48. Hi BD! I have a question for you, there´s lots of talk about eating fruit seeds along with the fruit, about how most nutrients are found in the fruit, etc. But, nobody is mentioning the importance of soaking those seeds, just like we should soak/sprout/ferment all kinds of seeds, nuts and grains.
    What´s your opinion about that? Should we eat the fruit without the seeds and soak the seeds before eating them?

    • Blenderdude

      Pedro, there is a great deal of merit in soaking raw seeds and nuts as doing so breaks down enzyme inhibitors, unlocking much of the nutrition that might otherwise go unutilized when ingested. Regarding the healthy seeds in fruit that is to be used in smoothies, it would obviously be up to the individual as to whether the effort involved in removing and soaking them is worthy the time and effort.

  49. OMG. I have been throwing in the seeds of apples and pears for the last 3 weeks into the vitamix for my smoothies. Holy heck! I’ve also thrown in whole kiwis in as well. Glad I found this blog just in time to correct things. Is there a book out here you can recommend?

    • Blenderdude

      Kiani, I’m sure you’re fine ;-). These seeds have to be consumed in rather large quantities to have significant ill-effects. But there’s not much benefit to eating them, so leave them out from now on. I was never able to find a book specific to this topic which is one of the reasons I wrote the article.

      • There is a huge benefit to eating these seeds and it is a common misconception that they are poisonous. I have eaten so many apricot seeds, which have the highest concentration of amygdalen, with no ill effects.
        Amygdalen is made up for 2 parts glucose, 1 part benzaldahyde, and 1 part hydrogen cyanide, which is in an inactive and perfectly safe form. By the way, when activated, the benzaldahyde is far more toxic than cyanide.
        For these elements to become activated, they need to come into contact with the enzyme Beta-glucosidase, which is only found inside of cancer cells. So the only time amygdalen can become toxic is when it is in the presence of cancer cells. All healthy body cells contain the enzyme rhodanese which neutralizes these elements and removes the toxicity. So even if you did have cancer, the amygdalen would only attack the cancer cells, and then be neutralized by all of your healthy cells. Much better than chemo or radiation, which cannot discern between healthy cells and cancer cells and kill them all.
        Eating fruit seeds with the WHOLE fruit is the safest way to consume, as it is how nature intended, and is perfectly safe.
        I stumbled on this post because I very much want to blend my seeds and pits into my smoothies and simply wanted to confirm that my vitamix could handle it. I used to buy bags of apricot seeds and grind them separately in a coffee grinder before adding them to smoothies, but really would prefer to throw the entire fruit in.

        • Blenderdude

          Erica, thanks for sharing your insight. There are many knowledgeable advocates of utilizing apricot seeds, although there is still plenty of debate over the “way nature intended” argument. But there is no question that your Vitamix can handle these seeds.

  50. Hi BD,

    Thanks for all of the great information! I was wondering what you had read/learned about the use of frozen vs. fresh foods. Is there a significant nutrient loss for frozen foods? If you know of any good articles I should look at, it would be great if you could post them! Thanks again!

    • Blenderdude

      Kyle, the nutritional content of frozen fruits and vegetables remains at whatever level it held when frozen. For this reason, sometimes frozen fruits and veggies can actually be more nutritious than “fresh,” if they were frozen relatively early in the harvesting process. With some “fresh” produce, it can sometimes be several days, if not weeks, from the time they were harvested until they actually reach your market. The actual freezing process itself does not diminish the nutritional value.

  51. After blending is there a desired time to drink before losing nutritional value?

    • Blenderdude

      Robert, yes! Immediately is best. Or, certainly refrigerate any unused juice/smoothie and consume asap. I usually don’t store mine for over 24 hrs.

  52. What health benefits will I get if I blend all the part of water melon and consume it,and does it also help in achieving weight loss.

    • Blenderdude

      Amaka, in addition to the health benefits I mentioned in the article, ripe watermelon contains extremely high levels of lycopene, which studies have shown can be helpful as a fighter of heart disease and cancer preventative. It’s also a powerful antioxidant. I have no knowledge of it being effective for weight loss, however.

  53. I peel everything that I buy in any store including healthfood stores because of the wax coatings. Even organic produce has carnuba wax on it and I can’t fathom coating my intestines with an indigestible substance. I eat the skins on anything that I grow in my own garden, however, Hulda Clark recommended peeling apples to insure that you weren’t eating the brown spots that had patulin mold toxin in it. Tough call. Vitamin C helps to detoxify mold. I actually chew grapefruit seeds because I read that they use triclosan in grapefruit seed extracts.

  54. Hello. My friend recently bought a juicer. I’ve been drinking vegetable/fruit smoothies I make with my personal blender, and asked why he chose a juicer over a blender. He said that blenders blend things so fast that vitamins actually break down, so blended drinks don’t have as much nutrients. My blender is not very high performance, and it leaves big enough pulps that I have to chew on (which I like). So I think I’m getting all the nutrients. But I am curious as to whether if it’s possible for a blender to break down vitamins. Any thoughts appreciated. Thank you.

    • Blenderdude

      Mami, I know of no evidence that suggests that just the speed of blending will adversely effect an ingredient’s nutritional content. Extended blending times of items blended on high speeds in high-performance blenders will lead to friction build-up and the resulting heat that is generated will gradually deteriorate nutrients. This effect is easily controlled, however, simply by monitoring blending times. If your blender leaves you with smoothies that contain “chewable” bits and pieces, then you almost certainly have not lost any nutritional value. However, you might not be benefitting from the maximum value of your fruits and vegetables.

      In the following article I point out some benefits of using a high-performance blenders. You might be especially interested in the section, “Health Benefits.”

      High-Performance Blenders: What’s the “Big Deal?”

      For the record, I am an advocate of juicing as well. I think both blending and juicing have a place in healthy diet.

  55. You’re Awesome BD!

  56. I was wondering why your body cannot break down food cell walls to a phytonutrient level ?

    • Blenderdude

      Cole, keep in mind I am not a doctor nor a nutritionist, but it is my understanding that several factors are involved, including a lack of good bacteria in the gut which aids in phytonutrient absorption, the presence of nutrient-inhibitors in one’s diet, and the body’s difficulty in breaking down cell-structure in plant-based foods, which can cause many nutrients to pass through the digestive tract unutilized. There have been studies that suggest a high-performance blender can assist with the break-down of the cell-structure of fruits and vegetables, making nutrients more readily available to the body.

  57. When I was at Costco viewing the live demonstration they used strawberries and I found no trace of seeds in the smoothie. I ended buying the vitamix 5200. When I use strawberries the seeds are not breaking down. Is there a way to get the results I was shown at the demonstration?

    • Blenderdude

      Riley, the 5200 is more than capable of breaking down your strawberry seeds. I recommend a blending cycle of at least 40 seconds – perhaps longer – on the “High” setting. You may want to use some frozen ingredients (the strawberries would be fine) and/or ice in your smoothie to counter the friction generated by longer blending cycles. Also, keep in mind the quantity of strawberries used will affect the blending times required. Good luck!

  58. i’ve read on a raw foods website(actually, on two) that the blender doesn’t actually get the amount of HP that is claimed by the companies, and that the blender needs at least 1500 watts of power to create the necessary friction of the blade to totally break down the cell walls.

    Can you tell me if this is correct?

    • Blenderdude

      Stephen, there has certainly been a lot of confusion over the listed horsepower ratings of these machines. Some were once advertised using their “peak” horsepower rating (a maximum horsepower output capable by the blender, but not one at which it would be expected to perform during regular usage). However, the listed wattage of a blender is generally a better indication of its power capability. I have not seen research specific to the 1500 watt threshold you mention, but there have been studies that show higher-horsepower blenders are capable of dramatically increased breakdown of the cell structure in fruits and vegetables when compared to blenders of lower power output capabilities. As these blenders continue to rise in popularity, I’m sure the research surrounding them will evolve as well. I will do my best to keep up with it as it emerges and share it here on the site.

  59. Would it be safe for the machine (Vitamix 5200) to put a whole avacado pit in? How to blend? Thanks.

    • Blenderdude

      Chloe, it is perfectly safe to put the pit of the avacado into the Vitamix. The blender will break it down very well, but it will change the texture, and possibly the flavor, of the recipe when incorporated with the rest of the ingredients you are using. You should keep this in mind when using the pit.

      • Same question, but mine is a vitamix 4500. Ditto for pinapple core.

        • Blenderdude

          Melissa, this should be fine to do in the TurboBlend 4500 also. Definitely utilize the core of your pineapple, too!
