Doctor's Note

If the title of this video made no sense to you, make sure you see the first half of Flaxseed vs. Prostate Cancer.

This reminds me of the experiment described in Is It the Diet, the Exercise, or Both? in which researchers try to tease out the individual effects of a similar composite treatment—a plant-based diet and walking—on the growth of prostate cancer cells in vitro.

The difference between what researchers say they're testing and what actually gets tested (like the "low" fat diet here) comes up over and over (for example in EPIC Study). The new Mediterranean diet study is another good example.

In the next video Flaxseed vs. Diabetes we'll see what hope our 7th leading killer has against the humble flax seed.

    What’s the percentage of a real low fat diet?

    • http://twitter.com/usefulDesign Useful Design

      @GENBL ^ 5-10% according to Doug Graham Author of The 80/10/10 Diet (80% carbs, 10% proteins, 10% fats/lipids). His rationale is that’s the ratio by calories that our closest primate consume. And that’s fats found in fruits and plants that you’ll get if you are consuming a high enough calorie diet to be getting the fuel your body needs to stay away from ketosis. I know plenty of peak athletes pro and amateur supervised by Dr Graham target 5-10% by calorie.

        Thanks! I’m eating more a 17-20% fat diet. I’ll have to stop eating nuts because they’re my only high fat food (no oil or prepared meal).

          As Dr Greger has observed while nuts are mainly made of lipids, they don’t seem to result in body fat increases the way other oils/fats do. I think the good Dr discusses in in one of his videos.

            agree with wideEyed, Nuts provide many benefits for our body. check more video study about nuts GENBL

    So, how much flaxseed should a man consume daily? Thank you

    • http://www.facebook.com/kathy.cultice Kathy Cultice

      The study was based on 30g/day which is about 3 tablespoons.

        Thank you

    Flaxseed, or ground flaxseed? Any difference?

    • http://twitter.com/dbark13 Dave Barker

      From the Flax Council of Canada – “Ground flax seed provides more nutritional benefits than does whole seed. That’s because flax seeds are very hard, making them difficult to crack, even with careful chewing. Grinding flax seeds breaks them up, making them easier to digest when eaten. Then the body can profit from all that flax goodness.

      If whole flax seeds remain unbroken, they may pass undigested through the body, reducing the nutritional advantage of eating flax seed in the first place.”

    I wonder how flax oil versus seeds would compare. i.e used in both the gerson and budwig protocols.

  • http://twitter.com/gkrall Gary Krall

    What is the recommend daily amount of flaxseed? Further how does that compare to the group in the study?

  • R. Ian Flett

    If you are grinding up flaxseed (removing the naturally protective shell’s integrity) , then you may as well add some ground sesame seed also as both contain valuable lignans. As the polyunsaturated oil in the ground seed is now vulnerable to light, heat and oxygen, you should store it in the freezer, or it will go rancid quickly producing harmful trans fats.

    • Derby City Vegan

      Trans fats are unintentional byproducts of the partial hydrogenation process. The oxidation process that causes rancidity will not cause the formation of trans fats.

    These videos about inhibiting growth of prostate cancer are important, because regarding prostate cancer the most important issue could very well be to inhibit growth, because it seems that the easiest way to get prostate cancer, is just to be screened for it !! Or could it be intirely preventable through a low fat vegan diet (with flaxseeds) ?

    • Thea

      I really like your point and think it applies to any cancer for any gender. Modern humans are exposed to so many carcinogens, we can’t truly live a clean life. Our cells are going to mutate. The only question (in my opinion) is, “Are we going to do what we can so that our bodies can fight the cancer?”

      It seems clear that a plant-based diet goes a long way to meeting this goal. I find it very empowering that there is something I can do to help myself. I am not helpless in the face of cancer.

      • Plantstrongdoc

        Thea, good point. You can`t do anything about your genetic makeup (early cancer, heartdisease or diabetes in the family), single handedly it is difficult to do anything about the pollution of our invironment, BUT that doesnt leave you powerless – eat mostly low in the foodchain, remember that fish is not a healthfood (unless you think mercury, dioxin, PCB og Prozac will do you good :-) ). The foodchain is now so polluted that flame retardants have been found in milk !! So in my opinion the best you can do, is to base your diet mostly on plants – that said, I don`t think that an occasional (rarely) pice of chesse, an egg, a fish or a piece of meat will kill you. Hence I prefere the term plant strong (plant based) instead of vegan – but thats a detail.

    Flaxseed diet results in – protective – high eicosapentaenoic acid (EPA) levels – not high prostatic Alpha-linolenic acid (ALA), associated with DOUBLE prostate cancer risk, OPEN ACCESS PEER-REVIEWED Article, December 28, 2012: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3532426/

    How much fat in the food is required for the fat soluble vitamins to be absorbed? Will enough vitamin K from for example kale be absorbed when only eating lentils or other practically fat free food?
