Doctor's Note

For those unfamiliar with that landmark Ornish study, see Cancer Reversal Through Diet?, which the Pritikin Foundation followed up on with Ex Vivo Cancer Proliferation Bioassay.

What else might help men with prostate cancer? See Flaxseed vs. Prostate Cancer and Saturated Fat & Cancer Progression. What about preventing it in the first place? See:

 Poultry and eggs may be related to cancer risk in a variety of ways:

Crucifers may also help with other cancers. See:

I’m going to highlight it in the next video Breast Cancer Survival Vegetable.

    Vegan means no animal products and is not open to interpretation.
    Thus, I disagree with the narrator’s claim that the Ornish prostate cancer study used a vegan diet or a “strictly plant-based diet”. You can at best call it near vegan.

    The error can be found on page 2 where you see that fish oil was consumed in addition to several other lifestyle changes:

    “Experimental group patients were prescribed an intensive lifestyle program that included a vegan diet supplemented with soy (1 daily serving of tofu plus 58 gm of a fortified soy protein powdered beverage), fish oil (3 gm daily), vitamin E (400 IU daily), selenium (200 mcg daily) and vitamin C (2 gm daily), moderate aerobic exercise (walking 30 minutes 6 days weekly), stress management techniques (gentle yoga based stretching, breathing, meditation, imagery and progressive relaxation for a total of 60 minutes daily) and participation in a 1-hour support group once weekly to enhance adherence to the intervention.10 The diet was predominantly fruits, vegetables, whole grains (complex carbohydrates), legumes and soy products, low in simple carbohydrates and with approximately 10% of calories from fat.11 The diet is intensive but palatable and practical. In earlier studies most patients were able to adhere to this diet for at least 5 years.”

      Has anyone found a vegan food option yet that has a source of DHA/EPA and astaxanthin in it? I still have a serving of salmon once a week and would like to cut it out of my diet if I could replace it with another wholefood that were plant based.

      • Cara

        Algael DHA suppliments are vegan,
        not sure about astaxanthin

      • Toxins

        There is no plant food that exists that has preformed DHA/EPA unless you get algae oil supplements which is not technically a plant.

        There is no need to consume preformed DHA and EPA. If you consume omega 3 in plant foods in the form of ALA your body will convert it to DHA and EPA if your omega 6:3 ratio is adequate, adequate being 4:1. The best way to do this is to eat plenty of fruits and veggies and minimize nuts and seeds. What nuts and seeds you could eat that have plenty of omega 3 are Flax, walnuts and chia seeds. Other nuts and seeds have very poor omega 6:3 ratios and should be eaten more in moderation.

        The National Academy of Sciences does not recognize EPA and DHA as essential. This means there is enough evidence for them to conclude that we can make enough of it without eating it in its preformed state.

        “Comparison of the PLLC n23 PUFAs:DALA ratio between dietary-habit groups showed that it was 209% higher in vegan men and 184% higher in vegan women than in fish-eaters, was 14% higher in vegetarian men and 6% higher in vegetarian women than in fish-eaters, and was 17% and 18% higher in male and female meat-eaters, respectively, than in fish-eaters This suggests that the statistically estimated conversion may be higher in non-fish-eaters than in fish-eaters.”

        http://www.ncbi.nlm.nih.gov/pubmed/20861171

        In addition, another study showed that despise this “theoretical” low conversion rate, there is no evidence of any harm so, the problem may not be in the conversion rate, but in the assumption that it is low.

        “There is no evidence of adverse effects on health or cognitive function with lower DHA intake in vegetarians”

        “In the absence of convincing evidence for the deleterious effects resulting from the lack of DHA from the diet of vegetarians, it must be concluded that needs for omega-3 fatty acids can be met by dietary ALA. ”

          This is informative thank you.

        • VegAtHeart

          Interesting arguments suggesting that taking algae oil supplements may be superfluous for vegetarians/vegans.

          They may even turn out to be worse than useless. In ‘Becoming Raw’ (2010), Davis and Melina argued on page 127-128:

          “DHA is the most highly unsaturated fat in the diet and also the most unstable (meaning it is easily oxidized by free radicals in the blood). Oxidized fats are bad news; they contribute to all sorts of disease processes, including cardiovascular disease. It’s possible that our bodies are smart enough not to bother making DHA when it’s not needed. In addition, it’s possible that when DHA is in our bloodstream, it’s rapidly transported to locations where it’s needed and incorporated into tissues, such as the brain and the retina of the eyes.”

          As you probably know, the supporting articles for algae DHA sources are often financially supported by algae oil manufacturers such as Martek Biosciences. I doubt authors of such articles would be objective. Until more thorough research on long-term effects is done, I would not favour consuming algae oil.

        Sorry Brandon for my repetitive information regarding the ratio, I forget that I already discussed this with you. Either way, I am sure others who have not seen this information will appreciate it.

        • elsie blanche

          Yes, I do appreciate it. Thanks.

        This is a DHA/EPA supplement sold by Dr. Joel Fuhrman. It is completely vegan and clean, if you feel that you need to supplement.

        The red stains on the bottom of dried out birdbaths are the astaxanthin-rich cysts of the green algae
        Haematococcus pluvialis. They’re also the source of astaxanthin supplements. Astaxanthin also appears in trace amounts in krill oil, shrimp, flamingo feathers etc.

        • Joe

          Just a note on the Nutrex – they have two types of capsules. One is gelatin, and the other is vegan..the vegetarian one is called MD formulas Bio Astin

  • rick

    Anyone know if Dr. Ornish eliminated all dairy in his cancer/diet study?
    I am writing an article for my local newspaper and don’t want to state that unless I am 100% certain.
