Dear Mark: Is Flax Bad?

503074250 6992bbbb6fDear Mark,

I’ve been researching flax and am ready to pull the plug on my dedicated flaxseed grinder. The kicker was seeing flaxseeds associated with prostate cancer. What’s your take?

Thanks to reader Clare for the thoughtful correspondence on flax. This is exactly why I love doing this blog. Research continues to unfold, and the conversation never fails to engage and inspire me.

As Apples know, I’ve been a flax supporter. Lately, I’ve been mulling that position. While I don’t think a single study’s results should rewrite the book on any issue, when a number of studies suggest that it may be linked to serious illness in some people, that’s enough to give me pause. And, well, it’s enough to incite me to do some digging – and pondering. Flax is one of those cases lately.

The deal is this. Flax seed is rich in a form of omega-3 fatty acids called ALA (alpha-linolenic acid). Omega-3 fatty acids as a whole (group) are especially vital for the development and ongoing well-being of the nervous system and for the health of the cardiovascular system. They improve lipid profiles, thin blood, and combat inflammation like nobody’s business. (You know how I feel about that one, eh?) They can also help curb insulin resistance.

Research time and again supports the role of omega-3s (again, as a group) in overall health; however, some studies and reviews over the last few years have linked high ALA intake (from both flax oil and milled seed) with higher incidence of prostate cancer. ALA blood levels are higher in response to flax oil intake than they are with milled seed intake. (Eating whole seeds isn’t recommended unless you’re looking for some serious abdominal havoc.)

I’ve always maintained that other animal-based forms of DHA and EPA offer more health-related bang for your buck, and I stand by that point. The preponderance of research supports the particular power of EPA and DHA in the omega-3 fatty acids. One study suggests that fish intake (rich in both DHA and EPA) actually reduces the risk for prostate cancer.

The bottom line is ALA doesn’t do much that DHA and/or EPA can’t do and probably do better. As avid Apples know, I suggest that everyone take a fish supplement. In the past I’ve seen ALA as a decent secondary choice for vegetarians and as a useful addition to a healthy Primal eating strategy (e.g. a bit of ground flax seed on some berries). The human body isn’t terribly effective at converting ALA to either DHA or EPA, hence the need for added dietary intake or supplementation. (An interesting side nugget: women’s bodies are a little better at this conversion. Research has shown that young women convert 21% of ALA to EPA (compared to 8% in men) and 9% to DHA (compared to 0-4% in men). The difference, apparently, is linked to estrogen levels.)

So, what’s my current suggestion in light of the potential prostate cancer link? If you’re a woman, the obvious point of the research isn’t relevant. Nonetheless, the underlying role of phytoestrogens in flax is nonetheless an important one. I’d say that healthy women can consume low to moderate amounts of flax without concern. Sure, a large amount of research suggests the protective effect of phytoestrogens against breast cancer (in healthy women), and this research includes flax. Nonetheless, a lot of a seemingly good thing isn’t necessarily better or even safe. My advice would be to use fish oil as your primary omega-3 source and keep the ALA on the lower side.

If you’re a man? Particularly an older man? I’d definitely suggest you make fish oil your principal source of omega-3s. Is it time to chuck the flax grinder all together? Based on the research, I’d at least put it into semi-retirement. (I’d suggest forgoing flax oil entirely.) In the meantime, we’ll stay on top of this one and let you know about any new developments on this front.

As always, thanks for your questions and comments. Keep ‘em coming!

  1. These are some comments about flaxseed oil that I have read that are quite interesting:

    Comments:
    “Have you seen this paper on ALA to DHA and EPA conversion?

    http://www.ajcn.org/cgi/content/abstract/88/3/801

    They claim that ALA from flax seeds is as effective as fish oil, while some previous studies questioned it’s effectiveness. If you have an access to the full text of the paper, could you comment on that? Thanks,

    (Name)

    Just peeked at the full text. The abstract is really incomplete!

    First of all, they gave flax at doses up to 3X the fish oil. Despite that, after 12 weeks they saw no increase in total erythrocyte n-3 with flax, while they did with fish oil. The flax actually caused a decrease in erythrocyte DHA, while the fish oil caused an increase. The flax did cause an increase in EPA and DPA.

    Well that pretty much removes any reservations I had about trashing flax oil as a supplement.”

  3. Here’s the way I look at this flax seed issue and herbivory more generally. Evolutionary thinking should lead us to look at things from the plant’s perspective. Specifically, does the plant want its foliage or seeds to be eaten or not? If the answer is yes, it wants to be eaten, then it’s unlikely that natural selection would favor plant genes that sequester toxins to repel or injure foragers like Grok and others. Such plants can probably be eaten by us in large quantity without concern for toxicity.

    In contrast, if the plant does *not* want to be eaten, then selection is likely to equip the plant with defense like spines, resins, and other phytotoxins to repel or injure foragers. It is this latter type of plant, the type that is by far in the majority among all plant species, that we should be concerned about. In fact, much of plant breeding has focused on breeding out these nasty wild type traits and replacing them with more benign (and tasty) qualities.

    Only through study of plant natural history and biochemistry can we determine which plants are safe to eat in quantity. But since such work is not always feasible then the safest policy is to only eat lesser-known plant varieties in moderation, if at all. As far as flax goes, why take the risk considering that there are other Omega-3 sources available that we are pretty certain do not poison us?

  4. I take as little PUFA as possible. They are way too vulnerable for radical oxygen damage. I take a tablespoon of cod liver oil in the morning for the fish oils and vit A+D and use coconut oil for mostly anything else (and some butter for the K2).

    Would paleolithic man have eaten flax? I don’t think so. He would have eaten fat fish.

    Just remember that flax oil goes rancid very quickly when you don’t keep it refridgerated. You wil need lots of vit E to keep it fresh in your body.

    My guess is that the walls of my bodycells will be more resistant to ROS (radical oxygen species) if they contain more staturated fat.

  5. Worried about flax seed and cancer risks? Specific to this article, check out http://www.beckwithfamily.com. Cliff Beckwith details his experience with an existing prostate cancer, and how he addressed it with the use of flax seed and flax oil. Better yet, check out http://www.healingcancernaturally.com or preform a google search for “Johanna Budwig”. This 7 Time Nobel Prize Nominee was responsible for developing an alternative cancer therapy that is based largely around flax oil and cottage cheese consumption, most people include the seeds in their regimen for a good lignan source. PS, lignans are incredibly concentrated in flax seed and have AMAZING anticancerous benefits. My opinion, the study that site the “possible” increase in prostate cancer risks was poorly performed, poorly cited, and leaves much to be desired in order to carry any real weight. No question about it, EVERYONE should take fish oil daily! That said, flax has a whole host of benefits on it’s own (fiber, protein, lignans, EFA’s) and should be used daily as well!

  6. Flax seeds are an incredibly healthy food. In science, the burden of proof always lays with the person making the claim. For example, I can say that water is not beneficial, but the burden of proving that claim lays with me.

    Now there are two groups of people concerning flax, the large scientific and nutritional community that supports flax as a healthy food, and the newer studies suggesting that flax can increase the chances of cancer.

    Those who believe flax is healthy can easily prove their claim, there are basic nutritional standards flax meets and excels at. However, those suggesting flax can cause cancer have only the results of ambiguous studies on their side.

    Should this be an issue for further research, sure.

    Should someone stop eating flax, throw away their grinder, reach around and up, grab their prostrate and run away?

    I doubt it.

  10. I think people should just use common sense on this one. Just think primal if anything. How many flaxseeds do you think you are going to be able find/pick in the wild?…probably not that many. I would just do a little in the morning or on a salad ground up. I personally have stopped using the oil many months ago because of the same reasons mark explained…DHA and EPA simply have more benefits per calories and dollar amount.

  12. what about the budwig diet and use of flax?

    joe wrote on February 15th, 2010
  13. If you don’t want to use flax, use chia. It’s better for you anyway. Just shop around – as it gets trendy it’s also getting expensive. Costco sells the exact same brand as Shopper’s Drug Mart for exactly half the price. (Weber’s). Also don’t be fooled by the folks who tell you the white seeds are better for you than the dark ones. Not true.

    I use ground flax now and then to make a “muffin in a minute”, which has egg, oil (any kind) and baking powder and is great for sandwiches. bp may not be primal but on the rare occasions when I really want a big old ham and cheese with the trimmings, or chicken salad, it more than satisfies for practically no carbs.

  15. I’m so confused now. It seems like the more I try to eat a healthier diet, the more I hear things like this that contradict what I originally thought. I eat 3/4 cup to 1 1/2 cups of flaxseed almost every day (as a pizza dough). Am I going overboard with the flaxseed? (I really hope not!)

  17. When I started putting flax seeds in my diet, I knew that it was a replacement for the traditional role of cod liver oil in the diet – I just didn’t want to eat cod liver oil! FF a few years, and I became absolutely convinced I needed fermented CLO for other benefits, not just the omega 3’s, and went that way, letting go of the flax.

    I think the heavy push for flax comes from the vegan contingent, just like the push for agave (although clearly agave syrup is far more processed than flax seeds). Before considering a return to flax, I’d want to know whether they were consumed the way we’re told to now (via oil or fresh crushed seeds, in daily sizeable amounts) by any traditional society. If the answer is no, I don’t need to go any further. If yes, I’d then start looking for the body of research on the matter.

    I thin kthere’s probably a reason why I can think of many references to the usefulness of flax (for linen) & linseed oil in history, but cannot ever think of a mention of anyone consuming flax seeds or flax seed oil, just off the top of my head.

    MamaGrok wrote on July 22nd, 2010
    • Not a vegetarian, but regarding flax not being in history: as far as I know, that’s right. But chia, that someone recommended a few posts back? That was historically eaten all over Central and South America. Besides the Omega 3’s, it also has a decent amount of protein, and the fact that it turns gelatinous in the presence of water is why the various peoples would use it as a trail food. It holds the water in your system and gradually releases it, keeping you hydrated. The Aztecs used it for sure. The traditional method is to soak it in lemon or lime juice with a lot of water, and then stir the resulting gel into a glass of water and drink it. My own experience is that if I drink a large glass early in the day, several hours later I really have to go, but I don’t feel dehydrated in between.

  18. I began using flax seed oil as an alternaive to fish oil. The main reason was to avoid MERCURY poisoning. Many cheaper fish oils can have traces of mercury, which btw, is cumulative in our bodies. There are some “mercury-free” fish oils. If making the switch back to fish oil, I would definitely recommend Mercury-free.

  19. I’m a vegetarian and I buy crushed flax seed from whole foods. I really will never believe that it has a connection to PC.

    In fact I read in a magazine that phytoestrogen does not make you into a woman. It does not give you man boobs. It has no feminizing effect at all.

    The phytoestrogens in soy was what they were talking about. The whole thing about soy giving you estrogen is a myth.

    “Phytoestrogen has no effect on estrogen levels or hormone levels or even testosterone.”

    Case in point: these scientists or researchers are making up things, and lying, in order to encourage a diet of flesh.

    Sounds gross right? Well just try to not dance to their tune. Be yourself and don’t be so easily influenced.

  20. I appreciate the vegetarians and vegans who posted here. Here’s a little bit on the vile lying meat industry:

    “The meat industry spends hundreds of millions of dollars lying to the public about their product. But no amount of false propaganda can sanitize meat. The facts are absolutely clear: Eating meat is bad for human health, catastrophic for the environment, and a living nightmare for animals” – Chrissie Hynde from The Pretenders, in the PETA website

    “You can’t tear flesh by hand, you can’t tear hide by hand. Our anterior teeth are not suited for tearing flesh or hide. We don’t have large canine teeth, and we wouldn’t have been able to deal with food sources that require those large canines” – Dr. Richard Leakey

    “Nothing will benefit human health and increase chances for survival of life on Earth as much as the evolution to a vegetarian diet.” – Albert Einstein

    ” [A]lthough we think we are one and we act as if we are one, human beings are not natural carnivores. When we kill animals to eat them, they end up killing us because their flesh, which contains cholesterol and saturated fat, was never intended for human beings, who are natural herbivores.” – Dr. William C. Roberts, M.D., editor of the authoritative American Journal of Cardiology

    “Since I stopped eating meat, I have noticed that my digestion is better, my thoughts are better, and I run instead of walking. […] I eat vegetables and all kinds of vegetarian food. I am a vegetarian. I am not a meat-eater.” – Vaslav Nijinsky, The Diary of Vaslav Nijinsky

    • Chrissie Hynde: That’s why we buy grass-fed meat — great for the environment, happy animals. This meat is also absolutely superb for human health.

      Dr. Richard Leakey: Stone knives have been around long enough for us to evolve around them. Eating raw and cooked meat drove our evolution to acquire our big brains.

      Albert Einstein: Brilliant guy but he’s a physicist, not a biologist. Plus, what is his reasoning for that statement?

      Dr. William C Roberts: Where’s the evidence that we are “natural herbivores”? Is it our lack of a four-part stomach that would allow us to efficiently digest cellulose for energy as well as micro-nutrients? How about the very few molars we have? Indeed, why do we have canines at all? A small stomach like we have necessitates a calorically-dense diet, which plants don’t provide. Besides, the argument is that humans are *omnivores*, not carnivores. Cholesterol? Our liver makes much more than we eat. Eat less, the liver makes more. Eat more, the liver makes less. Homeostasis!

      Vaslav Nijinsky: Greatly depends on total diet before and after the change. It’s very unlikely that the only change made was to cut out meat, so there’s no way to say that the absence of meat was the cause. Post hoc, propter hoc.

      I eat meat as well as massive amounts of vegetables, and I have never felt better since re-introducing meat. I’m not bashing vegetarianism, but the biological evidence points to modest consumption of meat as very beneficial.

  26. Hi there. I’m doing research on flax seed and its benefits when I came across your article.

    Let me just state here: There is no clinical study up-to-date that proves flax seed consumption to cause prostate cancer or any cancer for that matter.

    The research, done by Harvard showed that a diet high in ALA derived from ANIMAL sources was associated with a higher incidence of cancer.

    As Flax seed is high in ALA an assumption was made that the consumption of flax seed would lead to a higher incidence in prostate cancer. It was not part of the experiment nor was it proven to be so. On the contrary there are studies that proves the opposite.

    Have a look at this article.

  29. DHA and EPA: One of the many proofs that humans need to eat primal meat in order to remain healthy.

    DHA and EPA are the only forms of omega-3 that the body can use efficiently. These two forms are also found only in – MEAT. Plants have omega-3 but only in the ALA form, which the body cannot use well enough. Yes the body can convert ALA to EPA and DHA, but at too little amounts.

    It is essential to have a 1:1 ratio of omega 3 to omega 6. Plant foods are high in omega 6 and high in the useless omega 3. So if someone is eating a plant based diet, this person is basically only getting omega 6 fatty acids, which is pro-inflammatory.

    Humans are by nature, meat-eaters. Not herbivores, vegetarians or vegans.

    Peter wrote on November 23rd, 2011
    • DHA and EPA are synthesized by algae, not animals, and their dietary necessity compared to ALA is not at all clear, e.g.
      http://www.ajcn.org/content/92/5/1040

      “Substantial differences in intakes and in sources of Omega-3 polyunsaturated fatty acids existed between the dietary-habit groups, but the differences in status were smaller than expected, possibly because the precursor-product ratio was greater in non-fish-eaters than in fish-eaters, potentially indicating increased estimated conversion of ALA. If intervention studies were to confirm these findings, it could have implications for fish requirements.”

      And more to the point, if any of this was significant, we would see increased mortality for vegans/vegetarians, which isn’t borne out by real-world experience.

    ‘ asked on Just the Flax, Ma’am: There are a lot discussions and articles online about the supposed connection between flax seeds (ALA) and prostate cancer – suggesting that more flax consumed = increase chance of prostate cancer. I haven’t found this issue addressed on your website (sorry if I missed it). Can you comment? Thanks!

    The latest meta-analysis of prospective studies found that, if anything, alpha-linolenic acid (ALA, the omega-3 fat in flax) was protective against prostate cancer. Men consuming more than 1.5 g/day appeared to have significantly lower risk (the amount found in about a tablespoon of ground flax seeds).

    One of the reasons there’s been so much conflicting data is that ALA is found in great foods (dark green leafies) and less than great foods (meat), and so ALA intake is not necessarily a marker of healthy eating. What you want is a randomized controlled study of men with prostate cancer. Give half of them flax and see what happens. And that was done! (full text here)

    Researchers at the University of Texas Anderson Cancer Center took a bunch of men with prostate cancer about a month before they were to go into surgery. Half were put on a few tablespoons of ground flax a day and after surgery their cancerous prostates were examined. The proliferation rates of the cancer in the flax-eaters were only half that of the controls, confirming the test-tube studies done on prostate cancer cells suggesting that flax can indeed slow prostate tumor growth.’

  32. My understanding of ground flaxseeds is that they contain lignan phytoestrogens, which are very different from phytoestrogens. On top of that, Flax Oil is very different from ground flax seeds in that it doesn’t have the lignan content that makes flax so beneficial.

    there’s an article here from Cornell University about phytoestrogens (and flax) and breast cancer and prostate is mentioned towards the end.

  35. I’m a physician, and looking at the article you referenced, the studies were observational studies, and even as such, the data did not represent a strong link between flaxseed intake and prostate cancer.

    From the article:

    “It is quite uncertain at present whether the effect on prostate cancer is real. Even if it were real, the protective effect on fatal coronary heart disease would probably outweigh these possible negative effects, especially for men with an increased risk of heart disease.

    “In the United States, 6 times more men are diagnosed with coronary heart disease than with prostate cancer, and almost 8 times more men die of coronary heart disease than of prostate cancer (CDC/NCHS, http://www.cdc.gov).

    “Furthermore, prostate cancer occurs at an older age: >40% of coronary heart disease patients are 50% of prostate cancer patients are >75 y old when diagnosed. “

I was severely depressed for about 15 hours; it was the most frightening experience of my life, I felt truly awful. It was only when it was over that I thought it might be connected to the supplement I had taken that morning. Has anyone else had a reaction like this? I’m just curious.

  37. I would say this is a double edge sword.

    The positive side: studies show reduced risk of prostate, ovarian and breast cancer in people with high levels of lignans in the the body. This is because, Lignans bind testosterone which has potential to speed up tumor growth.

    The negative side: many men can not convert the ALA in flax seeds to EPA and DHA. Since a high ALA content is linked to prostate cancer, this is reason for concern.

    My understanding is that high insulin levels inhibits the conversion of ALA to EPA and DHA. Unfortunately over half of our population has high insulin levels. If you are overweight it’s a safe bet you have high insulin levels.

  38. Dr. Gerson realized the need for the right type of essential fatty acids. He experimented with many types of oils and found that in all cases, fats other than flax seed oil stimulated tumor growth and even the regrowth of tumors that had resolved.
    Flax seed oil is an omega 3 fatty acid containing linolenic and linoleic acids that inhibit the production of pro-inflammatory cytokines and lipid mediators and thus reduces inflammatory responses in the body. It attracts oxygen at the cell membrane assisting in transport of oxygen into the cell. It also helps carry vitamin A through the blood stream. Lignans come from part of the fiber of the seed and are high in protein. Although they can provide health benefits for certain conditions, high lignan flax oil is not allowed on the Gerson Therapy as it introduces too much protein.
    Seeds, including flax seeds, have an important substance in them called an enzyme inhibitor that keeps them dormant until they are in the right environment to sprout. This enzyme inhibitor can also inhibit human digestive enzymes and interfere with good digestion.

  40. OK, Flax is safe when combined with cottage cheese (A Sulfurous Protein). Flax is not safe and may be harmful if you eat it alone. All this was discovered quite a while ago by a renowned German biochemist called Dr Johanna Budwig.

    The key is the cottage cheese. With it you have a very safe statin and anti-cancer causing product. Without it you have a loaded gun.

    1/4 cup cottage cheese mixed with 2 TBsp ground flaxseed (kept in the refrigerator after grounding) Ground Flax loses its effectiveness quickly if not refrigerated.

    Google the free PDF “DIRECTIONS FOR BUDWIG’S WELLNESS PROGRAM” . It’s all spelled out there along with her statement on pg 2, “Such oils should be consumed together with foods containing the right proteins, otherwise the oils will have the opposite effect, causing more harm than good.”

    Look for Budwig’s books on Amazon, and also read the testimonials there as well. ’nuff said.
