Coconut Palm Sugar – What’s the Skinny?

Without a doubt, there is an incredible level of chatter about the latest sweetener to take the spotlight among those of us who are paying attention to these kinds of things. Coconut palm sugar is made from the nectar of the coconut palm, and while that might sound exotic, you first should ask, “what’s in a name?” Coconut palm sugar is, as advertised, sugar. It is not to be confused with coconut oil which has many health benefits that I talk about here.

Incredibly, even in the internet age, it is extremely challenging to garner meaningful information about the nutritional content of coconut palm sugar. What I have learned is that apparently the testing offered up by researchers in the Philippines (who are deeply invested in the global marketing of this product) has shown that, compared to other natural sweeteners, coconut palm sugar has a relatively low glycemic index, meaning that it may not raise blood glucose levels as much as other sweeteners like honey or maple syrup.

The worry here is that this “low glycemic index” likely indicates that coconut palm sugar contains a lot of fructose, a sugar that doesn’t raise glucose, is highly glycating (meaning it increases free radicals and inflammation) and doesn’t signal insulin release. Insulin is released by the pancreas in response to glucose consumption and helps trigger our sense of satiety so we know it’s time to quit eating. High fructose consumption from soda beverages is a strong candidate for explaining the direct relationship between drinking high fructose sweetened beverages and obesity.

If you’d like to learn more about how damaging fructose really is, I strongly recommend you watch Dr. Lustig’s video:

In trying to find out just how much fructose coconut palm sugar contains I was frustrated when the only reference was found on Wikipedia, and if you follow the link, it is information provided by the Philippine Coconut Authority.

The fructose content is worrisome indeed.

Beyond the fact that coconut palm sugar destroys the tree’s ability to produce coconuts (think coconut oil), we really need to recognize this sugar for what it is.

The best advice is to stop consuming foods that are sweetened, with anything. In the end, this will go a long way to helping you lose your desire for sweets in general.

    Hello Dr. Perlmutter. I am a 40 year old woman who has began a steady progression of painful idiopathic neuropathy over the past two years. After several misdiagnoses and a trip to Johns Hopkins, I am still at a complete loss as to what is causing my diseased state. A medical friend suggested reading Grain Brain and I just got it in the mail last week.

    I have been gluten free for a year now and have not noticed a significant difference, but it appears as if there are other tweaks you recommend that I am starting to incorporate as I delve deeper into the book. One of these changes is sugar intake. I gave up drinking wine as it seemed to exacerbate my symptoms and began craving sugar. I am very careful and usually use Stevia, however, there are certain items I like that contain sucralose or xylitol. What is your opinion on these alternative sweeteners?

    Thank you in advance for your kind attention.

    • David Perlmutter

      If someone is looking for a sweetener, I am okay with them using Stevia. I note the same in Grain Brain.

      • Cat1234

        Yes, I read that. But are the other alternatives damaging? For example, once in awhile I crave ice cream or an iced latte from the coffee store. My local specialty food store makes a sugar free gluten free gelato with xylitilol that is very yummy. Also, the coffee store has a sugar free peppermint mocha, and the syrup has sucralose in it. Of course these are processed/nutrient low and not optimal, but are they harmful?

        • Kristin Morrill

          yes they are harmful but if only a rare indulgence maybe you can tolerate them, try going without for a month then try it and see how you feel

        • Xylitol is a sugar alcohol which has gotten the green light from the like-minded Jonathan Bailor, but he warns that it causes upset stomachs in those not able to process it and to not use it in excess. Sucralose, aka Splenda, has recently (past year) been very highly correlated with diabetes though I don’t know the details of the study.

      • Lucy

        when i think of honey and maple syrup i can’t help but think there’s some goodness in there too. but oh to keep the portions tiny…so harm doesn’t offset the good…is there such a thing?

        • Lisbeth Laursen

          A good question. I too think there is something valuable in honey (good quality!) but wonder how much is healthy.

      • Sarah

        Dr. Perlmutter, I’m 51, female and also have suffered with very painful peripheral neuropathy for 5 years now. (Especially in the feet, which makes it really hard to walk). I have been strictly gluten-free and casein-free for 19 months now. My question is, after we reduce ALL carbs and sugars to the minimum possible, is it possible for the peripheral nerves to heal, and approximately how long will it take? I am also taking all the supplements that you recommend on page 224 of Grain Brain. Please, is there hope for us? Thanks so much, Sarah

  • ri

    funny i just came across coconut sugar the other day at the supermarket-i stopped to take a look at it since ive heard about it before from a raw vegan who consumes copious amounts of it and although i am in need of a non sugar sweetener without any kind of after taste i left it on the shelf and kept walking-first off its very expensive and second to me sugar is sugar-natural or not-i havent had a chance to try stevia so i occassionally use small amounts of honey if i must have a sweetener but im trying to get away from sweets other than the occassional dark chocolate that i like to indulge in. Im no doctor but i say stay away! no matter how you package it -its still sugar and your much better off without it! im sure its better than white sugar-but its like smoking a cigarette with a little less nicotine thinking its better for you..by the way Dr Perlmutter you discussed some wonderful supplements and i just wanted to mention that ive been feeling so much more mental clarity and calmness and focus drinking ginseng tea (no sweetener added) so i bought the supplement-would you recommend this supplement?

    • Lisa Valantine

      Dr. Perlmutter – On the subject of coconuts – do you recommend the thai green coconuts in your dietary approach?

  • Kristin Morrill

    What about lohan…monk fruit…brand name Nectresse?
    Is that OK I think it MAY be?

  • Maureen McKerracher

    Dr. Perlmutter:
    Great interview today! I always learn something new
    listening to your talks. You’ve made a difference in
    so many people’s lives!
    Thank You!

    • David Perlmutter

      Thanks for your kind words Maureen, and thanks for tuning in for my appearance!

  • Lynda Schwemmer

    Sounds like it’s on a par with agave nectar.

  • susannae

    Its not going to happen. I’ve tried many times to give up sugar, and the cravings NEVER go away!!!!! Im sick of hearing that the cravings go away!

    • tannngl

      They do. Worked for my husband and I. But you’ve got to get them out of the house. Obsess to eat onlylow carb, fats and proteins. Those foods leave you so full, you just quit thinking of sugar.

      • ri

        HELP!! what do you do when you have someone visit and they bring a box of sweets from the Italian bakery and they want you to try a sample of every sweet treat-cannoli and eclairs sighhhh-how do you ever so politely decline without hurting feelings???

        • Kemahsabe

          “Those really look great, and I appreciate your thoughtfulness, but for health reasons I don’t eat things like that any more.” Then change either change the subject or tell them about ‘Grain Brain’.

          • JC Rataushk

            My reasons are not only to drop some weight, which I’mdown about 15 lb but when I’m older would really like my brain to come along with me to the end of my trail, and stay as healthy as possible.

        • tannngl

          It’s a fact. You will have people try to derail your new life and health! Happens when you quit smoking too. Those who see you losing weight and in control of your eating with ease feel threatened. They don’t want to give up their sugar! And feel they should! So UNCONSCIOUSLY

          • tannngl

            they tempt you skillfully with the substance they are addicted to!

            What Kemahsabe said is right on. Even though those sweets look like heaven at the time, YOU should decide when to indulge in a treat and it’s not whenever your friend Jan comes over which might be with some frequency. Don’t let someone else control you! You are captain of your own ship. And you look so good!!!!!!!

            We, hubby and I, do have treats but we limit them to planned times like on Christmas day, on birthdays. Point is WE decide and it’s not often. We are both on the downward track! To perfect weights! He and I both have lost 25 pounds and it has not been difficult.

        • Lindsey Larkin

          I would just say, “Thank you for bringing those over and thinking of me! However, I have been cutting these foods out of my diet for health related reasons. I don’t mean to offend you, but I’ve come so far and don’t want to slip!”

        • ItalianScallion

          Hey, put on a pot of coffee and make sure you take a good jog the next morning.

        • jm

          Why would you care about “offending” them? *They’re* the ones being offensive by bringing that trash into your house when they know about your change in lifestyle. You can be polite when you say, “I don’t eat that stuff anymore, please don’t bring it over again.” But good lord, don’t worry about them being “offended” when you decline to eat it! I wouldn’t even SAY “sorry to offend you” or “I don’t mean to offend you,” as their feelings have nothing to do with it. In fact, a good friend of mine has a TERRIBLE habit of offering me junk all the time. I get downright *snippy* with my refusals (“C’mon, you know I don’t eat that s**t”) in the hopes that it’ll get her to stop… and she’s never been offended by it, lol!

          • health2share

            I would sure appreciate some suggestions on how to eat or order at a Chinese restaurant because I realize so many sauces and vegetable dishes have fair amounts of sugar in them. This would also apply to Thai food, which I love. I have been a vegetarian my whole life so please keep this in mind when making suggestions.

        • jake3_14

          “Thanks, but I’m on a diet. Please help yourself, though; they look delicious!”

    • Perlmutter fan

      I am really craving something sweet right now, but I’m having a glass of water and then…I’ll go to bed. Still craving….eat some nuts.

      • Amy Johnson

        Eat dates!

    • Victoria Murphy

      I know, I felt like you do when I started LCHF eating. Snack on three macadamia nuts or a small amount of at least 70% cocoa chocolate and that usually curbs the craving for something sweet. The more you adopt this way of eating the less are the cravings but it takes a couple of months for your body to adjust. One day you will be surprised by your lack of craving for something sweet or how eaily it is satisfied. Keep going, Victoria x

    • Pam Dorsey

      after realizing how much better I feel without the sugar the cravings do go away!! Mind over matter 🙂

      • David Perlmutter

        That’s great Pam!

    • jmo

      Odd, I’ve given up sweets and as long as I don’t “cheat” I don’t crave…

      • David Perlmutter

        The period that it takes for cravings to dissipate will differ person to person. Also, ask yourself what part of the craving is physical, and what part is psychological.

    • jake3_14

      Some people find that putting 1/4 t L-glutamine powder under the tongue when a sweets craving hits reduces or eliminates the craving. Chromium picolonate (capsules) also help reduce craving over a longer period.

    • connie

      You want something sweet and delicious youtube paleo brownies by squishymonster they are yummy and use honey and dates for sweeting. I put cashew butter on top sometimes to die for, and all natural.

    • Erica

      I gave up sugar on March 18th of this year. I now do not crave it. I still want it, sometimes, but I don’t crave it. I do add a little stevia or xylitol to tea, but drink my coffee unsweetened now. Takes very little sweetening to satisfy me and I used to put 1/4 cup of sugar in my tea and coffee!

    • chrysalid2000

      They do if you give up starch as well. All starches, even legumes and starchy vegetables. I have no cravings when I am being a purist. My hyperphagia leaves and does not come back unless I eat something sweet. Sometimes old habits die hard. But don’t mistake a habit for a craving. They are not the same, biochemically. Also, you have to drink a lot of water. I don’t even crave fruit.

  • Suzanne

    Water Kefir can be quite difficult to grow but since I changed to Coconut Palm Sugar with a pinch of bicarb it is growing like a crazy thing. The sugar is consumed by the Kefir. The result is not sweet but palatable enough to drink in order to get all those lovely little probiotics into my gut.

    • Lisbeth Laursen


  • Great post.

  • Madiha

    Amazing! Dr. Perlmutter, I’ve listened to, read and implementing all the things you have written in myself, my family and my patients for the last two years. I’m a holistic family physician in south bend Indiana (we actually have mutual patients), so thanks for being such an inspiration, and helping me bloom as a physician!

    • Barb Stults

      You say you are a holistic family physician in south bend Indiana, I live near there and would like to know where you are located so I could make an appointment.

  • HeidiMarie

    I recently read that taking a tablespoon or two of coconut oil will totally curb your sugar cravings

    • Lindsey Larkin

      I was eating cold coconut oil when I had sugar cravings, thought it was just myself! Now I’m going to look into that more 🙂

    • sluzen

      Coconut oil or MCT (medum chain triglycerides) oil is the fastest way, or so they have said, to put your body in ketosis. When in ketosis, you are not hungry. When I first started consuming these products in the morning and afternoon, I just had no desire to eat.

      These are non-inflammatory fats, perfect for healing. Incredible for you skin by taking internally. But you can also use it on your skin. My skin became almost pore-less, so to say.

      Most other commonly used fats, which are long chained, are inflammatory. I personally feel that all or most diseases are based upon inflammation. Knowing that, I try to stay away from ingesting substances considered inflammatory.

  • Bernadette

    I like sweets as much as anyone but it’s not worth the trade off to me. I now try and fast after dinner around 5:30 p.m.until I wake up in the morning around 5:00 a.m. for my morning coffee.

  • Scott

    I have found that an IR diet of not eating for 16 hours a day covers a multitude of sins when it comes to carbs, etc.

  • Bridget Burton

    Does this mean it’s extra virgin coconut oil is not good to use/eat?

    • David Perlmutter

      No, coconut oil is still part of my Anti-Alzheimer’s trio.

      • Maryann

        Thank you for all of your life changing work Doctor! I finished the book and want to begin daily coconut oil; should I wait until I am at my goal weight? 2 teaspoons per day (not to mention avocado and olive oil) adds up to a lot of additional calories. Thank you!

        • David Perlmutter

          No reason not to start now. Once your body is burning fat instead of carbs, it won’t matter.

          • Maryann

            Thank you very much!

  • Hill Perez

    Hello Dr. Perlmutter,

    Thank you for replying to my
    facebook comment I got so excited!! I read your book and I found it to be an
    eye opener. My grandmother past away last year because of diabetes and she was
    in the early stages of Alzheimer, it was really heartbreaking. We are Mexican
    and our diets are very high in carbs we love our Pan Dulce. I am so happy I
    found your book I have been recommending it to everyone. Also I have changed my lifestyle since pretty much all my family including my mom have diabetes and heart
    disease. I have slowly started to transition into a gluten free, high fat and low carb diet
    and it is amazing how I feel no more brain fog and I have energy every morning
    to get up and prepare my healthy meal and at night after work I am still
    energized enough to go workout. I am so happy I can concentrate at work now and
    not have to take energy drinks and pills!! Again thank you so much for all of your research and putting together this amazing book.

        Hi Everyone,
        What should vegetarians eat on this diet for protein? I do not want to support the cruelty and the negative environmental effects of factory farming.Is Tempeh ok?Any suggestions? Thx

        • chrysalid2000

          Nuts, seeds, kale, spinach, other dark leafy veggies, here is a link http://www.healthaliciousness.com/articles/vegetables-high-in-protein.php

          Also, never consume high protein veggies with tannin, caffeine, calcium or phytic acid (do some research) because these block absorption of the nutrients, particularly iron and if you can always eat these foods with a food containing a lot of VItamin C as this increases the absorption of the iron in the body. Make a salad with dark green leafy veggies and be sure to add some tomato and you will be good to go.

  • susan

    I’m totally amazed, but I do not have the sugar cravings anymore and I don’t get hungry anymore. But I only felt like this when I totally eliminated all potato/rice/tapioca/wheat starch. If you are using the other starches as replacement(as I did before I finished the book) to wheat you are not eliminating the sugar.

    • Cindy

      I am a few months into the WFGF lifestyle and want to share what happened today. I was meeting people at a mall. Called them upon my arrival and they were in the food court. As I rounded the corner, this sickenly sweet stench was overpowering – it was the smell of waffle cones being made at an ice cream establishment. I am totally amazed at my reaction! Wanted to gag from the overbearing sweetness. I’m guessing this means if I can rid myself of the desire for sugar, anyone can! I feel soooooo much better since reading Grain Brain. As a woman who recently lost her mom to Alzheimer’s, I am grateful for your work, Dr. Perlmutter.

      • Lisbeth Laursen


  • Trial Error

    Who cares if it’s 100% fructose if you are having a teaspoon or two – 10g of fructose, unless your liver glycogen is 100% full. And even then you’d end up with 4g fat perhaps.

    Personally I avoid empty calories as much as possible but am not against using a teaspoon of sugar, a half cup of ice cream, a fruit or a sweet potato, which also has fructose.

    • Runner52

      Using coconut palm or stevia sparingly 2-3x a week is not an issue for me either. I have cleaned up my diet quite well since reading Grain Brain, but I refuse to become obsessed with the new plan. Yes, my mom died of Alzheimer’s…I eliminated all gluten and bad fats plus markedly reduced sugar. I am feeling better and digestion continues to improve on Week 5.

    • sluzen

      o-o-oh Kay!

  • Sandra Clagett

    Do you know anything about Swerve? It has Erythritol, oligosaccharides and natural flavors. I’m suspicious about “natural flavors”.

    • sluzen

      Sandra, as you probably know, the term “natural flavors” is one of many terms a corporation can use to hide under (much like snakes hiding under a rock) to avoid transparency about their ingredients which the informed public might not agree to. Sounds like a good term, does it not?

      • JC Rataushk

        Yes natural flavor &natural color can literally be from anything under the sun. Example beadel shells for color!!

  • Linda Dye

    How do I find a doctor in the Asheville/Waynesville/Maggie Valley area of North Carolina who subscribes to the Perlmutter approach? I go to a cardiologist who is pushing statins and claims I have no diabetes in my genes or diagnosis, despite the fact that I had a diagnosis, went low carb and now it would only show up with the liquid glucose test. I have read that statins cause diabetes, and do not want mine to creep up again. Cholesterol does not scare me, but diabetes and Alzheimers do.

  • Ineka

    I am wondering if organic coconut nectar has the same result as coconut palm sugar???

  • BrianB

    I was curious if you have looked at the NHANES study that was published in Cell Metabolism? I would hope that their negative findings on the health benefits of a high protein diet can be attributed to a still high dietary carb content and resulting glycation of the proteins…?

  • Coco Bean

    Wow, this not a well-researched article at all! Before you go and blast a product you may want to pick up the phone and call a coconut sugar manufacturer and ask for a Certificate of Analysis and find out some of the true statistics on Coconut Sugar. If your argument is that people should consume ZERO sugar, then all sweeteners will have their flaws. But if you allow a little room for some sweeteners (most humans will not give up ALL sweets), let’s at least have a fair article on which ones of those are superior.

    As for your claim that coconut sugar production kills the ability of the tree to produce coconuts for coconut oil, that is completely unfounded and untrue and being propagated by ONE particular manufacturer of coconut oil. If you’d like, I can put you in touch with a woman who runs a coconut sugar business and is the daughter of a world-renowned coconut expert who travels the world showing people how to make the most of coconuts. A mature coconut palm has several flower stalks and can be used SIMULTANEOUSLY to produce coconut nectar on one side (by cutting into the flower stalk) and coconut oil on the other (by letting the flowers grow and produce mature coconuts). A coconut palm will consistently produce nectar that is dried into coconut sugar for up to 50 years, so the tree is not damaged either.

    If you’d like to point a finger at something that is decreasing the amount of mature coconuts for finished goods like coconut oil, then have a good look at the COCONUT WATER industry which is burgeoning out of control and tends to strip entire plantations of coconut palms of their fruits while still green (that’s when they’re best for drinking). When in this stage of growth, the coconut husk has not yet dried and can therefore not be used to produce a jute-like fiber that is commonly used in Asia to produce rope, rugs, and even large mats for erosion-control on hillsides. Additionally the meat is not yet mature so obviously no coconut oil can be extracted. The husks simply rot away in giant piles.

    • Sheridan Kennedy

      this is very interesting to hear Coco Bean. I hate seeing all those young coconuts in the rubbish because people just suck the juice out and throw them away. And talk about how healthy it is. While being completely ignorant of the impact this health fad is having on coconut palm communities. Sure, the plantations are making lots of money, but from what you say this fad for young coconuts also has a negative social and environmental impact.

    • sluzen


      Did you study Robert Lutzig’s info on the biochemistry of good and bad sugars? He shows that there is dangerous health concerns about certain sugars. He also explained how certain companies have refused to reveal the sugars and their amounts in there products. It would be great to know that the food processing industry which makes coconut palm sugar is more transparent. Do you know if they are?

      In my mind, much too often when we are dealing with many of the corporations, we are just dealing with folks who have chosen service to self, called greed, at the expense of public health.

      I would say the same for our corporate government who just take legislation written by the corporations and pass it into statutory law. Neither one of them have our best interests in mind.

    • Sterling Solomon

      Thanks for performing life-saving surgery on this MD’s botched operation.

  • Coco Bean

    Coconut Sugar = Around 75% Sucrose, 15% Glucose, 10% Fructose

    Though the sucrose can be said to convert to fructose and glucose during digestion, this is very different than comparing to agave or HFCS who both are around 50% fructose BEFORE entering the body.

  • Coco Bean

    My comments are erased just like that? That’s one way to win an argument. Well censor my comments Doc, but at least go do your research now. Thanks.

    • David Perlmutter

      Coco Bean: Please note that your comments have not been deleted, and are still visible here in the comments section.

      Thank you for contributing to this ongoing dialogue.

      • All Things Equal

        Dr. Perlmutter,
        Do you have a chart that shows the percentages of what each sugar type contains?

    • All Things Equal

      hi Coco Bean, Can you share with me the sugar breakdown for coconut nectar?

  • sluzen

    From listening to Robert Lustig, I assume all sugar alcohols (i.e. xylitol) are no-nos. On stevia or inulin fiber (combines very well with stevia to make the stevia taste better), I can find no where online info on it’s fructose content (measured n grams).

    I had liver problems with erythritol when I used to drink a lot of tea containing it. think I may of done some major and hopefully temporary damage to my liver. I assumed, at the time, it was something wrong with the erythritol itself. But now I think it was either the alcohol or fructose (extreme toxins/poisons) content that was causing the problem. If only there were someplace online that had a list of the kinds of sugars and alcohols contained in these low-caloric sweeteners then I would be able to ascertain what the problem with each is before consuming it at all. I have a deep desire to know so that I can explain it to others and if it is poison, I will not be tempted to consume even a little. Plus I need to know what to toss out in my kitchen.

    And BTW, I found Robert Lustig’s information quite informative. For those of you who are information junkies and just life-long consummate students, if you haven’t listened already, you will have many “a-ha!” moments with his info. (You mght have to take notes, though.)

    I am enjoying food that contains small amounts of grass-fed meat with larger amounts of cooked (in water, generous on butter) fresh veggies. I’m thinking this is a very simple and good way to go for both weight loss and health. You are seldom hungry, especially if you take doses of MCT oil in the morning.

    I purchased a head of cabbage and made 4 meals out of it. (Such a deal!) Cabbage has 1.8 grams fructose (evil sugar) and 2.0 grams glucose (good sugar) per 100 grams of cabbage and tastes very sweet. Compared to an apple or a mango, this is very low. And as David Perlmutter says, since it (cabbage) is bound to fiber and contains lots of water, digestion of the sugars are slowed down and you don’t have any sugar/insulin spikes (at all – ?).

    My thoughts are that the processed food industry (pick a corporation) has harmed me by hiding ingredients in their foods that if I knew what they were, it would have been against my will. I would not want to argue with them whether or not these hidden substances cause me harm physically. However, I would love someday to get in a lawful action with them about harming me by going against my free will choice. I delight in thinking about how exactly that could be done using contract law and the Uniform Commercial Code. Tee-Hee! It could put them in an untenable position.

    • sluzen

      Geez, darnit! thought the above comment was deleted by me. Sometimes I don’t get my thoughts through as well as other time. Now, too much time has passed and I cannot delete it again. It’s a little embarrassing.

  • sluzen

    I am in chapter 4 of Grain Brain, but have gone over the Robert Lutzig’s video (above).

    More than 6 months ago, I drank lots of tea sweetened with erythritol. After some time it dawned on me that my nausea, pain, etc., in my digestive area was caused by the erythritol. I assumed the erythritol had some kind of toxic chemical in it. That led to an impacted liver and other chronic digestive problems.

    After studying Robert Lutzig’s info it dawned on me that erythritol contained alcohol sugar (toxic) or fructose (toxic in a processed form, like erythritol, but not in, say, fresh strawberries because it is bound to cellulose fiber). Either one of those would cause an impacted liver. Isn’t it amazing what surprises the food processing industry provides us with (sar.)?

    It would be appropriate in this situation to put on our lawful (not legal, because you can have legal fraud, but can’t have lawful fraud) thinking caps on, and come up with a surprise the food processing industry just can’t resist. Think ye not?

    I don’t know whether my liver is permanently damaged or not. Time will tell.

    So let it be known what health challenges fructose or sugar alcohols can do to your quality of life.

      contained alcohol sugar (toxic) or fructose (toxic in a processed form,
      like erythritol, but not in, say, fresh strawberries because it is bound
      to cellulose fiber). Either one of those would cause an impacted
      liver. Isn’t it amazing what surprises the food processing industry
      provides us with (sar.)?

      It would be appropriate in such a situation to put on our lawful
      (not legal, because you can have legal fraud, but can’t have lawful
      fraud) thinking caps on, and come up with a surprise the food processing
      industry just can’t resist. Think ye not?

      I don’t know whether my liver is permanently damaged or not. Time will tell.

      So let it be known what health challenges fructose or sugar alcohols can do to your quality of life.

      Thank you for posting this. I was about to ask about Erythritol, and the next post down was yours. I agree with your points and am going to toss it in the trash.

    I’m thinking of all the times I’ve heard diet gurus say, when you crave sweets just eat a carrot or an apple and it will go away. People that tell you this are clueless. When I get a real honest to gosh craving it can go on for months. I’ve been wanting glazed donuts for about 6 months now. The thought of gaining weight is not enough to overcome it. BUT when I found out my intollerance for gluten was causing me to rock with excruciating stomach pain and cause violent vomiting for hours, that seemed to improve my ability to ignore my desires, but that pesky small voice in my head continues to whisper “Just this one time won’t hurt!”. I think the commercials on TV help keep one’s cravings alive. Watching videos and reading newsletters about how poisonous sugar and wheat are help to remind me. I also heard about a supplement on Dr. Oz’s show that seems to really curb my sweet addiction. N-acetyl L-tyrosine or NAC for short. I think it really does help. I admit I’m an addict. If I bring sweets into the house I am helpless to fight it. They cry out to me and there is no rest until I’ve hogged them all down. A drunk can’t keep beer in the fridge. A drug addict can’t keep pain pills in the medicine cabinet. I can’t have sweets in the house because I don’t act like normal people around them. That’s just the way it is.

    I am only one day into the grain brain lifestyle and I feel extremely hypoglycemic. Shaky, weak, light-headed…I am not diabetic (that I know of), but I feel terrible. I have felt this way in the past when I have skipped a meal and I usually eat something with sugar and feel better within minutes…I don’t want to eat sugar so what should I do to feel better?

  • JC Rataushk

    Well thats it then , I’ve always watched my intake of sugar , so this is definatly out. Thanks for the info

    Coconut palm sugar shouldn’t be demonized since refined whit sugar is processed more than the coconut sugar plus it has nutrients. Now granted as with all things this sugar should be used sparingly or in moderation.

    • David Perlmutter

      Yes, but when a “healthier” option might exist, we should look to that instead.

  • Ruth Griffith

    no one should eat sugar or any food with sugar in them sugar feeds cancer and there are so many great fruits to eat no salt either it breaks down in your body as sugar if u want salt eat sea salt

  • Chana

    Dr. What do you think about the “just like sugar ” that in opinion of Jane Barthelemy has no fructose ,and zero carbs. I really want to know your opinion, especially because she is the one that recommend to watch your video and opened my eyes to see that I was poisoning my family using coconut sugar ,thinking that was a healthy option.

  • Chana

    What about this one.
    Is this a healthy option ?


  • Sterling Solomon

    What a jackass article. MD? Seriously? and you can’t even research the fructose, sucrose, glucose content of palm sugar? It took me 1 minute. Less! The sad thing is you might have patients who rely on your integrity with knowledge because of those letters after your name, which in this case mean Most Disappointing.

    Glucose- 2.00%, Fructose- 2.90% and Sucrose- 84.98%

    Sugar Regulatory Administration (SRA) of Diliman, Quezon City on 02 November 2006 conducted an analysis of samples of coco sap sugar submitted by Philippine Coconut Authority, Diliman, Quezon City on 20 October 2006/ The Entry Number is 1394. Method used: HPIC, CarboPac, Amperometry. The results are: Glucose- 2.00%, Fructose- 2.90% and Sucrose- 84.98%. It was correctly certified by Flor S. Nepomuceno -OIC, Agro-based Materials Laboratory.

  • Great David Thanks for sharing the research experience with us. I always follow you with your blogs. I also read much about Coconut sugar from internet but I am still confused which sis best for a normal human being free from diseases so that it will remain free from sugar based diseases like Diabetes etc. Plz pay some attention in future blog.

  • Jim

    So David, what is the chemical composition of coconut sugar? Sucrose, dextrose, glucose, fructose or some other sugar? What other nutrients could or should it have in it. Once I know what is in it, I might be prepared to try more or less of it. More science please.

  • Claudia Benson

    doesn’t make sense to me ‘The worry here is that this “low glycemic index” likely indicates that coconut palm sugar contains a lot of fructose, a sugar that doesn’t raise glucose, is highly glycating (meaning it increases free radicals and inflammation) and doesn’t signal insulin release.’ So coconut is fructose? – good or bad?

  • Taz

    I’ve read a lot of negativity directed at sugar. GIVE UP SWEETS!!! Not no, but hell no!!! Get off your butt and exercise. I am 63 years old, have never been fat, I eat what I want and am in good health. Why because I exercise and stay fit. If i had health problems that dictated that I not consume sweets then it would be different. But most of the health problems I hear people complain about are due to them being couch potatoes. You simply want to exist longer because when you deprive yourself of what makes life rich and interesting you are not truly living.
