Six hundred years ago, people living along the coast of Carragheen County, Ireland started using a red algae, which became known as Irish moss, to make a jellied dessert, now the source of carrageenan, a food additive used as a thickener in dairy and nondairy products, as well as a fat substitute—perhaps most famously in the failed McLean Deluxe.

In 2008, I raised a concern about it. We had known for decades that carrageenan had harmful effects on laboratory animals, but this was the first study done on human cells to “suggest that [carrageenan] exposure may have a role in development of human intestinal pathology.”

But, that was all five years ago, though. What’s the update? Well, after the activation of inflammatory pathways was demonstrated in actual human colon tissue samples, Europe pulled it from infant formula, out of an abundance of caution.

The latest suggests carrageenan consumption could possibly lead to a leaky gut, by disrupting the integrity of the tight junctions that form around the cells lining our intestine, which form the barrier between the outside world and our bloodstream. This was an in vitro study, though, in a petri dish. We still don’t know what effects, carrageenan has, if any, in whole human beings. Some researchers advise consumers to err on the side of caution, and select food products without carrageenan, accusing the FDA of ignoring its “harmful potential.”

Personally, after having reviewed the available evidence, I continue to view carrageenan the way I view acrylamide, another potential, but not proven hazard. Acrylamide is a chemical formed by cooking carbs at high temperatures. So, should we avoid eating a lot of these foods, like the EPA suggests? Well, “Food safety concerns must also be considered…[in the context of dietary] consequences.”

Where’s it found the most? Already unhealthy foods. So, sure; use your concern about the probable carcinogen acrylamide as just another reason to avoid potato chips and French fries. But, until we know more, I wouldn’t cut out healthful foods, like whole-grain bread.

Similarly, I’d use potential concerns about carrageenan as additional motivation to avoid unhealthy foods. But, until we know more, I wouldn’t cut out more healthful foods—though I would suggest those with inflammatory bowel disease, or other gastrointestinal problems, try cutting out carrageenan, at least temporarily, to see if your symptoms improve.

  1. I’ve been wondering about this, especially since two of my favorite vegan products — a creamer and a candy bar — contain it. They both do qualify as junk food, so given the emerging evidence, perhaps it’s time to seek out new delights ….

      1. Dr. Greger,
        I have only found ONE omega-3 (EPA/DHA) vegetarian capsule that does not contain carrageenan!!! It is WAY expensive. I bought a 60 capsule container of it but I am sadly thinking of having to go back to Nordic Naturals brand recommended by Dr. Weil which is expensive too but not as much for the dosage one gets. I don’t want to use fish sources anymore if I can help it, for ethical, environmental, and potential toxic compounds that can be in them. Should I just give up and accept the cheaper vegan algal sources that all contain carrageenan? Do you have any suggestions?




        1
        1. VeganMujer: My understanding is that the carrageenan is in the container, not the oil itself. So, IF the carrageenan bothers you, you can simply cut a slit in the capsule and suck out the oil. Or some people just bite down. You have to hold your lips together pretty tight so the oil doesn’t go spurting out. :-) But from what people report, it works. Note that you can buy algae based omega 3s in dropper form and avoid the container completely. That’s just another option for you in the future.




          1
          1. Thanks for these tips. Since there is a strong “repeat” from the Pure Encapsulations brand anyway, I might as well graduate to the pure oil and just down it like you suggest! I didn’t realize the carrageenan was in the waxy capsule portion so that is really important to know, and I may try the squeeze method if the daily dose Dr. Greger recommends is cheaper than an oil dropper version.




            0
          2. What brand do you buy in a dropper? I’m having a really hard time finding algae oil in a liquid form. I found one marketed for kids by Nordic Naturals but costs $25 for a 1oz bottle which would just be a 15 day supply for an adult.




            0
            1. Alison: Someone recommended to me: Deva. I never actually used it though. I can’t say anything about it. The most economical thing is to probably just get the pills and suck out the oil — if you are really that concerned about the carrageenan. Personally, I’m not that concerned, especially just the little bit from some pills. Good luck.

        2. Thanks for writing, VM. Carageenan has only been found to be problematic in animal models of inflammatory bowel disease; it may or may not affect humans the same way (see https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5410598/ for more info). Or see Dr. G’s video at: https://nutritionfacts.org/video/is-carrageenan-safe/. If you have a family or other history of gut diseases, you may want to avoid it; however, the amount you’d be taking in a supplement will be very low, and the anti-inflammatory effect of the fatty acids should make it safe.




          0
          1. Thank you for the response. I wonder if there is more to this than one NIH article though, since I understand carrageenan has been banned throughout Europe now, and Calista products company worked for a year to delete it from its soy and almond milk products.




            0
  2. Suggestion to all: email and call the vegan companies that add carrageenan to their products……vegan ice creams, almond milks, soy milks, treats, etc….and tell them you are no longer going to be a customer until they remove the carrageenan from the said products. The companies will listen.

    1. Also, many canned dog foods have carrageenan. I expect cat foods as well. The poor animals have no say in what’s in their food. I wrote one company about licorice root in their dog food with possible links to kidney failure as it is harmful for humans; they said their diet experts were not concerned even with animals consuming it every meal.

      1. It’s true too for cat foods. When choosing food for my cat, I read labels on every brand in the pet store. Majority of them do contain carrageenan along with other fillers. I wound up finding a limited ingredient gluten and grain free brand of food, Simply Nourish, that is just water, tuna, potato, tapioca starch, sunflower oil and added nutrients. Before, my cat was throwing up her food with alarming regularity. In the two weeks since I switched her diet to include both wet and dry forms of Simply Nourish, she hasn’t thrown up once. :)




        2
        1. A regular diet of Tuna is extemely dangerous for cats and commonly leads to thyroid issues later in life ..it is extremely high in murcury and other contaminants and is so palatable that once cats are hooked on tuna/fish its very hard to get them off anything else.

          Skip the tuna. Really, ..not good at all. A raw diet is ideal, but if you cant find/make a good one with all essential enzymes etc, look for a LID (limited ingredient) wet food ..one protein source and one carb (not the same as grain) can be potato etc




          1
          1. Instinct canned, Weruva Cats in the Kitchen canned, and Fancy Feast classic formulas do not contain carrageenan. Raw food is the best, but you’ll need to experiment. My cat does fine on Primal raw, but throws up the Instinct raw (though he’s fine with canned, go figure?) Like with human food, you have to read the labels on everything, and avoid the bad stuff.




            0
          2. I’m guessing canned salmon would be a better diet for Kitty. Way more omega-3 and less contaminants than tuna, AFAIK. My Dad told me that back in the -twenties and -thirties in rural Oklahoma canned salmon was considered fit _only_ as pet food. It was a heck of a lot cheaper then; British Columbia was a seemingly bottomless well of salmon then. Now, even here in BC it’s typically up to $5/can.

    2. Elsie, I wrote to Turtle Mountain Foods back in May, and asked them to remove carrageenan from their So Delicious Coconut Milk products (I love the creamer, beverage, yogurt and frozen dessert, which all contain it). I was told that they are reformulating these products and will be removing the carrageenan sometime in the future. In the meantime, I am making do with Organic Valley Soy Creamer (no carrageenan, but doesn’t taste as good) and Whole Foods Organic Almond Milk, one of the few non-dairy mylks that doesn’t contain carrageenan. The stuff is in everything!




      0
          1. I’m sorry. Silk AlmondMilk is actually the one without carrageenan (although most of their other non-dairy products include it.) I wish this weren’t the case because I’d much rather support Turtle Mountain over Dean Foods.




            0
  3. I’ve always wondered what your take on this was because of the reliability with which carrageenan causes inflammation. It is used very successfully and frequently to induce inflammation in rats and mice to test the efficacy of anti-inflammatory products, foods and medicines. And a search on pubmed ( http://www.ncbi.nlm.nih.gov/pubmed/?term=carrageenan+and+inflammation ) yields greater than 3500 hits for Carrageenan and Inflammation.

    So for my patients that have severe inflammatory issues (fibromyalgia, Rheumatoid arthritis, Lupus, Crohns Disease etc.) I do warn against this additive as well.
    So who carries carrageenan free almond milk?
    Whole Foods Market used to have a store brand Organic Almond Milk that didn’t contain carrageenan but it was pulled from the shelves because it was found to not be organic.
    So I direct these patients that like almond milk to Trader Joe’s because their store brand of almond milk is Carrageenan free.
    Thanks for the update!

    1. I buy Whole Foods 365 Organic Almond milk unsweetened & it doesn’t have carrageenan. Ingredients: organic almondmilk (filtered water, organic almonds), tricalcium phosphate, sea salt, potassium citrate, organic locust bean gum, gellan gum, organic sunflower lecithin, vit A palmitate, ergocalciferol (vit D2), DL-alpha tocopherol acetate (Vit E).

      I knew about carrageenan for years and avoid it. Always read labels even with prepared foods. I noticed Costco’s prepared foods contain carrageenan.

      If you’re buying canned dog food, read the label. Chances are carrageenan is in it.

      Toothpaste from health food markets also may contain carrageenan. Read the label.

    2. Whole Foods brand, 365, has organic almond milk without carrageenan and it is the only brand w/o it that I have been able to find in NYC. Trader Joe’s organic brand, in fact, does contain carrageenan.




      0
      1. Interesting about your Trader Joe’s Brand. I buy their Almond milk (it doesn’t say Organic) and I just read the label again and there is no Carrageenan. Maybe NYC gets their Almond milk from a different manufacturer.

    3. Great point! I have mild osteoarthritis (self-diagnosed), so I will try to avoid this for a while. Such a shame that seaweed could be inflammatory. I guess pharmaceutical researchers use it because it is cheaper than meat.




      0
        1. I suppose that is a fair point. I’m not an MD, but I am a healthcare professional and have studied basic pathology, so I’m not likely as far off as many of my patients are at times. I base the diagnosis on the history (repetitive stress to the joints from work), location of pain, and characteristics of the pain. In my humble opinion, it is probably a reasonable self-diagnosis for me to make.

  4. Thanks for this great video! It confirms what I already know to be true…I have Crohn’s disease and through the elimination of some foods, I realized that carageenan was a common denominator in an increase in my symptoms. I avoid it like the plague, but it is frustrating to find it in many organic versions of foods (whipping cream, non-dairy milks, etc).

  5. Just another nail in the coffin of processed foods – vegan or not. Eat food that look like food – avoid food with a long ingredient list. Broccoli contains broccoli !




    1
  6. Wow, I’m glad to finally have that question answered! I’ve wondered. My husband recently found a soy milk at walmart with pretty simple ingredients and minus the carageenan. Guess we’ll be sticking with that from now on :)




    0
        1. Same here. In fact, all of the tofu and tempeh at my local grocery stores is organic (with most being specifically non-gmo project certified), and the soy milks are about half organic and half non. When buying specifically soy foods, I don’t think finding organic is a problem. People that eat processed foods with soy *in* them are probably consuming a lot more non-organic/gmo soy.

  7. Interesting blogs this week for me as an Ulcerative Colitis sufferer. I have been avoiding carrageenan for years since I heard it was used to induce UC in lab mice. Always keeping my ears pricked for a potential silver bullet, I recently came across something suggesting an intolerance of dietary sulfur as a potential contributor for IBD, particularly in encouraging already active disease, as I recall. Interestingly, carrageenan was cited from at least one source as a food extremely high in sulfur. Suspecting a possible correlation, I just had to try a low-/high-sulfur diet comparison to see if I could tell a difference from one week to the next. Unfortunately, there was no revelation to be had for me regarding dietary sulfur restriction. Still, thought some might find it worth hearing.

  8. This video is so disappointing to me. One of the things I like to make is vegan cheeses made out of nuts. My favorite vegan cheese cookbook is called Artisan Vegan Cheeses. Many of the recipes are carageenan-free, but the *meltable*!!! ones, which make *awesome* cheeses, use carageenan. Plus, I hate the texture that agar produces and love the texture that cargeenan produces.

    The one glimmer of light I take from this is the sentence about putting carageenan risk in the context of the whole diet. I assume that some carageenan nut cheese is probably OK. The problem is that I just don’t know how much is OK and I do drink a lot of almond milk and sometimes soy milk. I do try to get Trader Joes brand, but they don’t always have it in.

    Thanks for this video. I’ve been waiting with bated breath to see what you had to say. I was just hoping for a different outcome. ;-(




    0
    1. A related ingredient used by many of the nut cheeses in the book I mentioned above is xathan gum. If you have any information on xathan gum, I’d appreciate learning about it in the future.




      0
      1. I did a “Google Scholar” search using keywords “xanthan gum” & “human health;” i could not find anything negative regarding xanthan gum.




        0
      2. Xanthan gum has been studied far less than carageenan, and for every paper looking at it specifically there appear to be hundreds that mention its use as an “inactive” ingredient in controlled release drug formulations. A tough slog.

        There are no concerns with toxicity in long term xanthan gum feeding experiments, and xanthan gum has been injected in arthritic joints with no ill effect, perhaps some improvement.

        This study found xanthan gum induced interleukin-12 and tumor necrosis factor-alpha production in mice, which I believe might be considered signs of inflammation, but in this case also happened to stimulate immune responses to cancer and retarded tumor growth.




        0
        1. Darryl: Wow. That’s great info. And a very good point in regards to: no information does not necessarily mean no bad effects.

          I really appreciate you posting this info. If nothing else, while my brand of almond milk does not have carrageenan in it, it DOES have xathan gum.

          Thank you too for taking the time to check this out. I bet lots of people (not just me) will really appreciate it.




          0
      1. Yes!!! I’ve enjoyed being an artisan cheese maker. :-) And really, you could skip the recipes with carrageenan in them. But my thought is: If I get carrageenan out of my diet most other ways, then sometimes having it in my nut cheese might not be so bad. That’s the story I’m telling myself right now anyway. If nothing else, I still have a very expensive container of carrageenan sitting in my cupboard. Can’t let that go to waste, now can I? ;-)




        0
        1. That’s my hope. Since I have soymilk at least once a day, I’m hoping that even if I have it in my occasional meltable cheese, getting it out of my daily soymilk to good enough….? :-)

          1. I emailed Miyoko about this video. She’s great at returning emails (which makes her 1000x more fantastic in my mind), so we’ll she what she says. :-(

            I also started buying WestSoy and EdenSoy unsweetened shelf stable soy milk since I don’t like almond or rice milk, etc. I emailed Silk and put a comment on 365 Soymilk page about it. I think this video has caused quite a stir in the vegan community, so hopefully we can cause some change with our dollars.




            1
    2. Yes my sentiments too– i was quite disappointed because up until now i preferred the non-dairy drinks that had carrageenan, owing to the creamier consistency. My taste buds are capable of adapting however; the science leads the way.




      0
      1. gb: On the topic of adapting taste buds: That’s a good point. Though I think there is a genetic limit to how much we can adapt, it is wonderful that humans have this capability. It makes it possible to eat healthy AND happy.

  9. For those who use soy milk and wish to avoid carrageenan and other suspect ingredients–buy a quality soy milk maker and select your own high quality ingredients. Making soy milk is easy and the cost savings will pay for the machine in short order.




    0
      1. I’m using the SoyaJoy G4 to good effect.

        Here’s my process: soak or sprout 3/4 cup dry organic soybeans, then add to the machine with 1/4 cup dry organic brown rice or oats (for creaminess), fill water to the 1700ml line; you’ve got about six cups of sprouted soymilk less than thirty minutes later.

        Pour it through a nut milk bag–I find bags to be far better at filtering out pulp than included strainers–then whisk in 1/4 tsp sea salt (I use pink Himalayan), 2.5 tsp of calcium carbonate (provides ~500mg calcium per cup, all which your body probably won’t absorb, but I’ve accounted for that), 1 drop of 1000IU liquid vitamin d2 or half of a pulverized 2400IU vitamin d2 pill (120-200IU vitamin d per cup), and just enough vanilla extract to subtly change the flavor, maybe 1 tsp, without making it taste of vanilla.

        The final cost depends heavily on what you can get everything for, but I calculated the cost at $2/lb for the soybeans, and altogether it comes out to less than eighty cents per half gallon for unsweetened, sprouted, organic, calcium and vitamin d-fortified soymilk, as opposed to $3+ retail.




        0
        1. Thanks Kyle! SoyaJoy G4. I think I can find that one easily around here. Those are great tips, too, especially about oats for creaminess! I’m also thinking of a vitamix or alternative, and I’ve heard they do soymilk, too. Decisions, decisions…




          0
          1. A Vitamix could easily make soy or nut/grain milks as well, the only difference is that you’d have to cook the soybeans separately first to remove more of the phytic acid, whereas a dedicated milk maker will do the cooking for you. And the milk maker is a lot cheaper. But if you have the money, I’d just say go for the blender since it can do more.




            0
  10. Our family drinks a mix of soymilks and nut/rice milks, all without carageenan. For almond milk we use the Pacific Foods brand — Organic Original Almond. For Soymilk we use the Organic Original soymilk from WestSoy (we mix the sweetened and unsweetened versions to bring down the overall sugar levels). For rice milk we’ve been blending our own in a Vitamix from organic brown rice and mixing with Rice Dream – Original, which has no carageenan.




    0
    1. Thanks for the brand recommendations. Looks like i’ll be switching to these. The preponderance of research indicates that carrageenan be omitted from the diet (sigh).

  11. I have Crohns disease and avoid gluten and milk (I’m vegan). I’ve noticed that I don’t react well to vegan cheeses which probably contain carrageenan. So this may be a link. Also, I’ve noticed a sensitivity to soy, but seem to do well when I culture unsweetened soy milk into a kefir. So, this is great stuff to experiment with and I think I’ll try and make my own nut milks–that way I can control the processes and the cooking process, which seems to be linked to inflammatory issues. By the way, I seem to do better with the Crohns when I exercise regularly. Do you have some links to managing Crohns disease? Thanks!




    0
    1. re: “…I think I’ll try and make my own nut milks–that way I can control the processes and the cooking process…”

      For almond milk, the recipe that I have used in the past involved grinding up soaked, raw almonds. No cooking at all. :-)

  12. Umm, soymilk isn’t healthy…. did you seriously just say in this video soymilk is a health food??! I am amazed. It’s all kinds of harmful.




    0
    1. Emm: If you watch other videos on this site, you will see why soy milk is healthy. I know there is a lot of negative information out there about soy, but as you know, just because something is on the internet does not make it true.

      Here at NutrtionFacts, you can learn about what the science has to say about various subjects, including soy. Sources are sited under each video and Dr. Greger reviews literally thousands of studies every year in order to present an accurate big picture of what the studies tell us. What this means is that while you can no doubt find a study to tell you anything you want to hear, the key is to find out what the “body of evidence” tells us . The key is to find out if there is overwhelming evidence one way or another on a particular subject. Luckily our scientists have created a body of evidence which do give us relatively clear, overwhelming information on a wide range of nutritional subjects.

      Good luck.




      0
      1. Again, my sentiments. You beat me to the punch. People need to cite studies if they want to make (controversial) claims. This is obviously a pro-vegan website, so no need to provide citations for avoiding animal products, but if you are going to counter Doctor G’s statements– back it up with studies from peer-reviewed journals!




        0
        1. I view this site as a pro-healthy-eating website, not pro-vegan. If meat, eggs, dairy and fish where health-foods, then the topics would be about that. The bulk of evidence just happens to tells us to avoid (or seriously limit) animal-products. It is always OK to counter everything with reasonable arguments. Peer-review does not necessarily mean that it is the truth – it is often more complicated than that.

  13. My mother suffers from Lupus, I somehow managed to stop her having dairy and we are on soya milk, the alpro make. Anyone know if that is bad too? and where I could find soy milk or almond without Carrageenan? Thanks

  14. Hey, Thank you for this video. Where can I buy soy milk or almond milk without carrageenan from in the UK?? please.

    My mother suffers from lupus and I somehow managed to get her to drink soy instead of dairy, we are drinking the Alpro make. Not sure if thats bad too??

    Thank you!!

  15. Very good point that carrageenan is mostly found in foods that shouldn’t be part of a regular healthy diet. The only item I regularly consume that may contain carrageenan is non dairy milk. After reading labels on all the milk varieties available at my local supermarkets, I chose to stick with oat milk because it had the purest ingredient list next to rice milk. I prefer oat milk for it’s overall mouthfeel and flavor for use in teas and coffee, but I use rice milk when I need a large amount in recipes.

    I’ve also found that carrageenan is added to toothpaste. Old habits die hard, and I prefer a tooth paste over a gel. Since I’m spitting it out, I don’t concern myself with the carrageenan.




    0
  16. Man, this was not the result I was hoping for. And I noticed that all three carrageenan types were shown in that graph. Now I have to find a soy milk that’s non-GMO, unsweetened, and without carrageenan. (I don’t like the other non-dairy milks.) Any suggestions?!




    0
        1. Soy milk is actually one of the easiest non-dairy milks, especially if you use one of the dozens of automatic soymilk makers. These can also be used for making tofu at home, as tofu is a pressed coagulate of soymilk protein made using gypsum or nigari

          That said, Asian soymilk has a very different flavor from the kind adapted for Western tastes, much closer to liquid edamane than dairy milk. This is one reason for all the sweeteners and flavor additives. I personally couldn’t stomach it.




          0
          1. Yeah though if I make my own, that wouldn’t be fortified either. I guess I have to choose which is more important. Hopefully if I eat enough leafy greens and such, non fortified soy milk is okay?

            1. You will need a vegan B12 supplement, but if you eat your rainbow, you should be otherwise fine. If you live in a cloudy or northern area, especially if over 50, a vitamin D would be great. I use D2, which is vegan, but is less effective or at least not well absorbed. I have seen ads for a vegan D3, but you may have to order it online.

          2. Darryl, are all commercial nut milks likely equally bad for endotoxemia, even if there isn’t an emulsifier in the ingredients? For instance, TJ’s soy milk made from only soybeans and water…or Elmhurst brand nut milks with just almonds and water? Can you emulsify without an emulsifier?

            Thanks, always enjoy searching out your valuable input, here and on longecity.

  17. I caught wind of this ingredient after looking into the Dairy Queen Blizzard (which, unfortunately, I thoroughly enjoy no more). I appreciate your insight on this as I was curious about knowing more as well. Seems that the jury is still deliberating, but you are absolutely right that the food where we find Carrageenan is typically unhealthy anyway so we should avoid it as a precaution.

    By the way, love your site and the topics.

  18. Dr Greger, my question is this. What is the relation to carrageenan and Irish Moss in it’s natural state. As a raw foodist i find that Irish Moss is a wonderful component to making certain desserts such as raw cheesecakes. is there a difference>? I am hesitant to throw out the Irish Moss because I believe that the information you present is more for “processed” and “heated” forms of these certain drinks on the market that are mass produced for consumption. -thank you, Dart

  19. I am a bit confused…several people posted their chosen brands of almond milk stating that they are carrageenan free. I was just at Trader Joe’s a few days ago to check and both Trader Joe’s brand almond milk and the Pacific brand both contain carrageenan. I only buy regular, non sweetened, organic almond milk so what’s the deal? I am in the U.S., is it possible these companies sell carrageenan-free almond milk in some places but not others?

    1. Donna I know what you mean. What I do is stand in front of the alternative milk and search the labels. I have not found it at TJs either. Takes time doesn’t it?




      0
    2. Donna: That’s so interesting. Because of the discussion on this site, I checked my TJ’s almond milk ingredients just this morning – and no carragenan. I don’t know if it’s relevant or not, but I get the one that is unsweetened, but with vanilla added.

      So, either you are using a different version or TJ’s has different formulas in different parts of the country. The latter would be concerning to me.

  20. I wrote to Silk and their PR response was rather disappointing. They belittled a researcher who studies this, Dr. Tobacman, and rationalized its use by referring to in an industry sponsored review paper.

    1. Here is their response:

      Thank you for your recent e-mail to Silk®. We appreciate your interest in our products.

      When developing new products, we look for nutritional, ingredient, and flavor profiles that have a broad appeal to a wide variety of consumer tastes and preferences.

      Carrageenan is a naturally occurring thickener derived from red seaweed. It is also known as chondrus extract or Irish moss. There are two different types of carrageenan, food-grade and degraded. Silk® Soymilk uses only food-grade carrageenan as a natural thickening agent. It is used in many other food products such as cottage and cream cheeses, pie fillings, chocolate products, ice cream and salad dressings, among others. Degraded carrageenanis never used as a food ingredient.

      Recently there has been some negative press on the safety of carrageenan. An article published in 2001 by Joanne Tobacman, a researcher at the University of Iowa, claimed that carrageenan may cause lesions or cancer in the gastro intestinal tract (Tobacman: Env. Health Per., Vol. 109, No. 10, Oct 2001). However, the Tobacman study was performed using only degraded carrageenan, not food-grade carrageenan, an entirely different substance.

      Many consumers express concern that stomach acid could turn food-grade carrageenan into degraded carrageenan during the digestion process. However numerous studies on the digestion of food-grade carrageenan have shown that “it is either not degraded, not degraded to the same molecular weight, or not degraded in the same way” as the degraded form, and that the limited degradation that has been detected, has had “no effect on the gut wall”
      (Sept., 2003 http://www.inchem.org/documents/jecfa/jecmono/v19je05.htm).

      The safety of food-grade carrageenan was substantiated at a joint meeting of the FAO/WHO (United Nations Food and Agriculture Organization and the World Health Organization) Joint Expert Committee on Food Additives (JECFA) in June 2001. JECFA recommended an Acceptable Daily Intake of “not specified”, the most favorable ADI a food additive can receive. The JECFA review was based on extensive safety studies of food-grade carrageenan, including evaluation of such matters as degradation and carcinogenicity.

      Additionally, a review paper by Samuel Cohen, M.D., Ph.D and Dr. Nobuyuki Ito, adopted by the JEFCA in their deliberations, evaluated and rebutted the evidence of claims of carcinogenity. The paper states, “In long term bioassays, carrageenan has not been found to be carcinogenic, and there is no credible evidence supporting a carcinogenic effect or a tumor-promoting effect on the colon in rodents.” Drs. Cohen and Ito are well-known and respected cancer researchers.

      A review of existing scientific literature indicates that food-grade carrageenan is safe for all food uses. It is neither toxic nor carcinogenic. Silk products contain only the highest quality food-grade carrageenan available. We will continue to use only natural and safe ingredients in all of our products.

      Although we regret that Silk® products do not meet your specific needs, we hope you give one of our many different products a try.

      We hope this information is helpful.

  21. I emailed Silk and shared the link to above video. I asked them if they had any plans to remove carrageenan or had any products without it. This is their response…basically they are saying that food grade carrageenan is safe and that the studies showing it was harmful were done with degraded carrageenan. Is food grade carrageenan safe?

    Thank you for your

    1. Hi, Nan,
      I sent a copy of this letter to Carrageenan Researcher Joann Tobacman, M.D., at the Univ. of Iowa. Here is her reply:

      “In our published experiments, we have almost always used undegraded, high molecular weight carrageenan. In a few experiments, we used low molecular weight carrageenan, and clearly stated when this was used. Undegraded carrageenan is composed of the same fundamental, immunogenic, chemical structure as low molecular weight carrageenan. Undegraded, food-grade carrageenan contains more disaccharide units than degraded carrageenan.

      Industry studies of food-grade carrageenan have shown that food-grade carrageenan consistently contains low molecular weight, degraded carrageenan. Lower molecular weight carrageenan arises from exposure to acid, heating, and mechanical disruption.

      Joanne Tobacman, MD”

      My interpretation:
      1. The Silk rep was incorrect. Most of Tobacman’s studies used food grade (“undegraded”) carrageenan.
      2. According to her research, carrageenan used and labeled as “food grade” can still turn into degraded when exposed to acid, heat and “mechanical disruption.” Low-weight, the bad kind, was apparently found in “industry studies of food-grade carrageenan.”
      3. Either type of carrageenan is ultimately not healthy for the intestinal tract.

  22. Thanks so much for this! Like Jessica, I have been wondering about this ingredient for years. I believe my almond milk is the only product I have with it but I recently started making my own milk so that eliminates that!




    0
    1. Zuri: I wouldn’t mind making my own almond milk, but I have three issues with it. I’m curious if any of these issues bother you:

      1) Calcium. I could get all the calcium I need from greens, but I’m not very good yet about eating a steady amount of say kale. So, I rely on the solid 1 to 1.5 cups of almond milk that I drink every day to supplement the calcium I get from my food. If I drank the almond milk I made myself, I wouldn’t have the added calcium I get from store products. Does this concern you?

      2) Grit. I use a fine strainer, but the home-made I have tried to make always comes out (while of superior! taste) a bit gritty. I am very sensitive to texture. Do you have this problem? (I have made my almond milk in a commercial blender. I try not to go at full strength so that the pieces are big enough to catch in the strainer. But it never fully works out.)

      3) Storage. I don’t want to be making individual portions of milk every time I want some. So, I would want to make a big batch which I store in an air tight container. I don’t want to store in plastic and most of the available glass pitchers are pretty small. I did actually find one glass pitcher on Amazon that was a) big enough and b) had a good lid, but it was a hard find. And I wonder if there is something better out there. I’m curious what you do for storage.

      Just wondering. I would understand of course if you don’t have time to reply. And I would be interested if anyone else wants to comment on these issues.

      1. Hey Thea!

        Very valid concerns. I can offer some suggestions…

        1) Calcium. In all honesty, I do not pay enough attention to calcium as I probably should/probably will a bit later in life. I would however look at the amount of calcium present in almonds (or any other nuts you may add to the mix–I love cashew milk and I’m going to start mixing some nuts together to make milks and also “cheese” spreads). Also, look into what source is used to add calcium to the milk you consume. Maybe a simple calcium supplement would be equivalent?

        2) Straining. I know the grit you are referring to :) Throw some cheese cloth on top of the strainer before straining the mixture and reap the glorious benefits of using cheese cloth (a nice food quality brand–not a cleaning brand because it is much more permeable)! Feel free to blend the nuts as finely as you like–the cheese cloth will catch everything and you can wring it out to squeeze all the “milk” out. The remaining nut pulp can apparently be dried out and used as flour but I have yet to take that next step. I get my cheese cloth at Bed Bath & Beyond. I think It’s the only brand they sell–comes in a clear bag with a natural, cardboard label with black font.

        ALSO, I just got hip to a recipe that may change your life! I haven’t done this yet but apparently you can make your nut milks by blending NUT BUTTER with water, vanilla, sea salt, etc. I personally use dates to sweeten practically everything and they make the milk delicious (the longer the dates are in your liquid being sweetened, the sweeter it gets just FYI). If this works out, it will cut out some time consuming steps and leave more time to experiment with ingredients.

        3) Storage. I honestly recycle old glass bottles of all sizes and hope I have a future use for them. I put a batch of milk in an old rum bottle…then I started playing around with rum milk…lol yeah. But I typically do not consume the milk after 3-5 days (the new recipe may help extend that shelf life a few days tho). As far as sealing off some milk in an airtight container I have not done this but I’m sure you can find some info out there on how to preserve things that way.

        I hope this helps!!




        0
        1. Zuri: Awesome reply! Thanks for taking the time write out your response. I particularly like the cheese cloth idea. I also have a nut milk bag, but I haven’t tried using it yet. I sort of figured it wouldn’t necessarily be any better than the fine strainer.

          Also, the calcium issue is still a big one for me. I hate to take supplements if I can avoid it and I don’t want to get too much calcium.

          I really like that idea of starting out with a nut butter. I’m going to look into that.

          Thanks!!!

  23. Can you PLEASE tell me if using Irish moss (preparing it from the seaweed itself) is better for you than Carrageenan ? I have used and like the irish moss you soak or boil to make a gell like substance, I would hope that it not being processed makes it a better alternative.

  24. Dr. Greger: Would you please comment on this research as I cannot understand it. I have CLL and have kept it controlled with a vegan diet. Once had total white cell count of 90,000; now over 20 years later: 24,000. I use Silk Soy with carrageenan. Should I stop?

  26. Is there any research on the use of Irish Moss as a whole food used infrequently in small quantities (raw vegan treats), not just the isolated component (carageenan) like in store bought almond milk or in daily food items (quantity/frequency of ingestion). Does this make a difference whether whole or processed form or is the Irish Moss something to completely eradicate from the diet? Seems the Irish folks who used the whole food didn’t have leaky gut or colon cancer concerns..

    Weren’t the human studies on cadaver colon? Living humans have a variety of immune, metabolic, digestive pathways that really cannot be compared to a dead one when doing these type of tests.

  29. I love gelatin, but the problem is all jelly in this stupid bad country is made of carageenan, many foods are mix with that. I notice I get stomach bloating and pain when I eat gelatin. I can’t find gelatin that is made of animal collagen.

    1. AMee: Some people use “agar” (or agar agar) to make a fruit “jello”. It works pretty well and allows you to avoid both animal products (like gelatin) and carageenan. You might want to look into it.

      Good luck.

  30. Dr Andrew Weil published an A in a Q&A on his site that included research by Dr. Joanne Tobacman that discussed the previous assertion that undegraded carrageenan was ok but degraded carrageenan was not. Her study concluded that all forms of carrageenan are capable of causing inflammation. This article was from Oct 1 2012 and I’m shocked that so many products, including Orgain, use it still.

  31. I have a real problem with carageenan. I break out in painful, itchy blisters when I consume it. It took me over a decade to discover the culprit.

    I could scream every time I read a comment about how safe carrageenan is. The authors must work as P.R. reps for the big food companies.

  32. The scientific community at large continues affirmation that carrageenan is safe for even the most vulnerable populations. The esteemed and independent scientific body that reviews food additives for the World Health Organization, the Joint Expert Committee on Food Additives (JECFA), announced this June a scientific review finding carrageenan safe even for use in infant formula.

    The International Agency for Research on Cancer is the body which advises the World Health Organization on cancer risks for substances and their findings for carrageenan clearly state that “Native (undegraded) carrageenan was tested for carcinogenicity in rats and hamsters by administration in the diet; no evidence of carcinogenicity was found”

    JECFA’s thorough review considered the entire body of available scientific research on carrageenan safety for all population,
    incorporating the most relevant research into its final decision.

    All dietary studies intended to simulate the conditions of actual human consumption of carrageenan have found carrageenan to be safe,
    including a recent study of neonatal pigs that replicated the conditions of human infants consuming carrageenan in infant formula and found no safety concerns even in this most vulnerable population.

    Long-term studies of rodents and primates fed carrageenan
    (including infant baboons) have also found no indication of harm,
    carcinogenicity, or negative effects from carrageenan on the intestinal tract or other organ systems in test animals.

    There is no lack of information on the safety of carrageenan. There is simply continued mischaracterization and misapplication of science regarding this important additive.




    0
    1. Ingredients Solutions: I wonder why you call it an important additive. To me, important additive would be one that prevents disease because people can’t get that substance naturally and they need it. Even if you were right, and I’m not saying one way or the other, but even if you were right that carrageenenan is safe in amounts eaten normally by most humans, I don’t see how that makes it an “important additive.” What is your definition of an important additive? Note that this site promotes whole plant food based eating as the diet that optimizes nutrition and health.

      Your name, “Ingredients Solutions” is interesting. Where does that come from?

  33. I’ve got rid of it from my diet, not because it’s proven bad for humans, but because the animal studies showed it to be bad both in the food grade and the degraded forms. The degraded form was found to be carcinogenic, and the food grade co-carcinogenic. There is some breakdown of the food grade into the degraded form in digestion and food processing, as well.

    I know human studies are not done yet, but that isn’t a reason to go ahead and consume this thinking an absence of evidence is absence of harm. Tolerating it without symptoms also does not answer. Asbestos probably doesn’t cause symptoms when inhaled, just decades later, etc.

  34. I’m a bit confused here because there is a difference between degraded and undegraded Carrageenan. If there is one thing I don’t like it’s a bunch of chicken littles running around telling people not to use something based on anecdotal evidence. Where are the studies linking undegraded Carrageenan to harmful effects?

    Comments like these below: “Suggestion to all: email and call the vegan companies that add carrageenan to their products”

    Are asinine. And what scientific basis are you going to tell them to stop using it? Really, I mean now more than ever you have these trendy hipster food snobs who think they are on the cutting edge of health and nutrition but don’t have the science to back it up, or misinterpret already existing studies, looking for pieces of a study they can understand and pulling it apart, or my favorite, quote mining.

    This new chicken little phenomenon seriously needs to stop, it is harmful.

  35. Dr. Greger – While I’m less concerned about dietary carrageenan than most in this feed, I must applaud your moderate comments regarding research into carrageenan as well as acrylamide in the diet, in that it just doesn’t point in one clear direction yet. However, based on the information I was able to find, Carrageenan has been found safe for use in food by government regulatory bodies not only in the United States (U.S. Food & Drug Administration, and the U.S. Department of Agriculture), but also the Joint WHO/FAO Expert Committee on Food Additives (JECFA), and the International Agency for Research on Cancer (IARC). According to the World Health Organization (http://www.inchem.org/documents/jecfa/jecmono/v042je08.htm) and the European Commission on Health and Consumer Protection (http://ec.europa.eu/food/fs/sc/scf/out164_en.pdf), “…intakes of carrageenan and processed Eucheuma seaweed from their use as food additives were of no concern.” A recent review of available research (http://www.ncbi.nlm.nih.gov/pubmed/12389870) into carrageenans supported the WHO conclusion. But again, as you said, a wise approach is to limit intake as much as possible until more is known.

  44. HELP! I have looked for hours for a VEGAN ALGAE supplement for EPA-DHA as Dr. Greger suggests to take here: http://nutritionfacts.org/video/algae-based-dha-vs-flax-2/ … but I can’t seem to find one that does NOT have carrageenan in the ingredients. All the ones he listed have carrageenan in them that I could find… they also contain small amounts of sunflower oil or rice barn oil (maybe around 25mg) … does anyone have a solution to this? as brain health is important for vegans we need the omega 3!

    Maybe could make another video on this to update as the supplements were mentioned in 2008. Not sure what supplement the good doctor uses if any. Thanks!

    1. Jared Chan: The carrageenan in supplements is found in the outer shell. If you want, you can do what others do an slit the pill and suck out the oil. Another option is to get the algae based DHA drops.
      .
      As for the other oils that you will find in the supplements, those are usually there as preservatives as I understand it. Further, they are there in such small amounts as to not be a problem.
      .
      Does that help?

      1. This helps a lot! Thank you.

        I have two more questions though… I have read that all of the Algae supplements come with Vitamin E (tocopherols) and I have read that Vitamin E in supplement form can increase mortality… ( http://jamanetwork.com/journals/jama/article-abstract/205797 )

        My second concern is I’ve read that many Algae supplements have been made by using harsh chemicals such as hexane, in particular by the company Martek ( https://www.cornucopia.org/what-are-marteks-dha-and-ara-oils/ ) … and I’ve heard that the company Martek makes almost all of the Algae supplements from Dr. Greger on one of his replies to someone’s question.

        I’m just playing things very safe and don’t want to take something that could potentially harm me in the long run.




        0
        1. Jared Chan: I’ve never heard about algae supplements coming from a process that uses hexane. I don’t know enough to say how much of a problem that would be if it were true, but that would be a concern for me. I personally don’t think there would be enough vitamin E in the algae supplements to cause harm.
          .
          I want to be clear that after seeing the evidence, Dr. Greger took the position of generally recommending algae based DHA supplements. That said, I thought I would offer my own non-expert perspective in the hopes that it would help. The evidence for taking DHA supplements is not nearly as strong in my opinion as the evidence for taking vitamin B12 and vitamin D (if one is not getting enough sunshine). There is no 100% guaranteed safe way forward. You are taking some (trivial?) risk if you take the supplement and you are taking some risk if you do not take the supplement. You just have to make a decision or a plan and then go forward without stressing about it.
          .
          I’m getting the idea that you would prefer not to supplement. Here’s a potential plan: One option you have is to get your blood tested and if you have enough DHA, you don’t need the supplement. Dilemma solved. Even if your levels are low, you could first work to change your diet in ways likely to improve your DHA levels if you want to avoid supplementation. Then, after you have given that time to work, you could get tested again. It’s not like anything bad is going to happen over night if you take the time to try other options before supplementing. The one drawback with this plan is some uncertainty in the accuracy of the labs on this test. But it seems a reasonable plan to me.
          .
          I hope those thoughts give you a framework for thinking about the issue that you can use with your own values to make a decision. Good luck.

          1. Thea: Thank you very much for your comments. This has helps me out a lot. I still need some time to think about what I’m going to do… but I feel more comfortable now in making that decision. All the best!

  45. I understand there are three types of carrageenan – lambda, kappa and iota – and that they are molecularly different. I purchased the kappa carrageenan to use as a firming agent in making non-dairy cheese as was recommended. Is there a difference in health concerns particular to the type of carrageenan? Thank you.

  46. I use wild Irish moss, which is where carrageenan comes from, in my smoothies. I’ve read that the moss is not a problem. Does anyone know differently?

  47. When I consume soymilk or other soy products that contain carrageenan (different brand soy milk and polsoja sausages) i get sore bumps (inflammation) under my skin on my face, head, shoulders or back. My younger brother had a similar problem when he would use my soy milk (not that he’s vegan, but he’s had the same symptoms and in general does not eat tofu, plant milk or mock meat). I don’t have a problem with tofu, tempeh etc. so I don’t think it’s the soy itself.

  48. Hey Jeremy, thanks fror writing.
    There is data, nearly exclusively from animal studies, hinting at a harmful effect on the gut of carageeenan (see The Role of Carrageenan and Carboxymethylcellulose in the Development of Intestinal Inflammation, at: https://www.ncbi.nlm.nih.gov/pubmed/28507982). I would avoid foods made with this additive if you have concerns about developing inflammatory bowel disease (e.g., Crohn’s.) I don’t see any other evidence of harm at this point.
