DHA and EPA generally modulated different sets of genes, although a few common effects were noted. In our approach, we used preneoplastic adenoma cells which are a relevant model for target cells of chemoprevention. If verified with real time PCR, these results identify genes and targets for chemoprevention of colon cancer.

Our findings suggest that administration of n-3 FA (EPA and DHA) in doses of at least 1.5 g/day for a prolonged period of time to patients with advanced cancer is associated with an improvement in clinical, biological and QoL parameters. N-3 fatty acids, cancer and cachexia: a systematic review of the literature.

ScienceDaily (Apr. 5, 2009) - Docosahexanoic acid (DHA), an omega-3 fatty acid found in fish oils, has been shown to reduce the size of tumours and enhance the positive effects of the chemotherapy drug cisplatin, while limiting its harmful side effects. The rat experiments provide some support for the plethora of health benefits often ascribed to omega-3 acids.

Mercury, fish oils, and the risk of myocardial infarction. Guallar E, Sanz-Gallardo MI, van't Veer P, Bode P, Aro A, Gómez-Aracena J, Kark JD, Riemersma RA, Martín-Moreno JM, Kok FJ; Heavy Metals and Myocardial Infarction Study Group. N Engl J Med. 2002 Nov 28;347(22):1747-54. PMID: 12456850 Conclusions The toenail mercury level was directly associated with the risk of myocardial infarction, and the adipose-tissue DHA level was inversely associated with the risk. High mercury content may diminish the cardioprotective effect of fish intake.

Omega 3 fatty acids and the brain: review of studies in depression. Sinclair AJ, Begg D, Mathai M, Weisinger RS. Asia Pac J Clin Nutr. 2007;16 Suppl 1:391-7. Review. PMID: 17392137 This paper discusses the clinical studies conducted in the area of depression and omega 3 PUFA and the possible mechanisms of action of these PUFA. It is clear from the literature that DHA is involved in a variety of processes in neural cells and that its role is far more complex than simply influencing cell membrane properties.

Omega-3 augmentation of sertraline in treatment of depression in patients with coronary heart disease: a randomized controlled trial. Carney RM, Freedland KE, Rubin EH, Rich MW, Steinmeyer BC, Harris WS. JAMA. 2009 Oct 21;302(15):1651-7. PMID: 19843899 Conclusions Treatment of patients with CHD and major depression with sertraline and omega-3 fatty acids did not result in superior depression outcomes at 10 weeks, compared with sertraline and placebo. Whether higher doses of omega-3 or sertraline, a different ratio of EPA to DHA, longer treatment, or omega-3 monotherapy can improve depression in patients with CHD remains to be determined

"The results of the uniquely-constructed ERA JUMP Study were just released, a fascinating study of the relationship of omega-3 fatty acids to coronary and carotid plaque. The study adds insight into why the Japanese experience only one third of the heart attacks of Americans, and why Japan occupies the bottom of the list for least heart attacks among all developed countries. The Electron-Beam Tomography, Risk Factor Assessment Among Japanese and U.S. Men in the Post-World War II Birth Cohort Study (ERA JUMP), a collaborative U.S.-Japanese effort, compared three groups of men: -- 281 Japanese men living in Japan -- 306 non-Japanese men living in the U.S. (Pittsburgh, Pennsylvania) -- 303 Japanese Americans (having both parents Japanese without "ethnic admixture") living in Hawaii. The last group represents a group that is genetically similar to the group in Japan, but exposed to an American diet and lifestyle. Three main measures were compared: -- Blood levels of omega-3 fatty acids, EPA and DHA) -- Carotid intimal-medial thickness (CIMT, the thickness of the carotid artery lining that can serve as an index of body-wide atherosclerosis) -- Coronary calcium (heart scan) scores."

The effect of omega-3 FAs on tumour angiogenesis and their therapeutic potential. Spencer L, Mann C, Metcalfe M, Webb M, Pollard C, Spencer D, Berry D, Steward W, Dennison A. Eur J Cancer. 2009 Aug;45(12):2077-86. Epub 2009 Jun 1. Review. PMID: 19493674 Omega-3 fatty acid (omega-3 FA) consumption has long been associated with a lower incidence of colon, breast and prostate cancers in many human populations. Human trials have demonstrated omega-3 FA to have profound anti-inflammatory effects in those with cancer. In vitro and small animal studies have yielded a strong body of evidence establishing omega-3 FA as having anti-inflammatory, anti-apoptotic, anti-proliferative and anti-angiogenic effects. This review explores the evidence and the mechanisms by which omega-3 FA may act as angiogenesis inhibitors and identifies opportunities for original research trialling omega-3 FAs as anti-cancer agents in humans. The conclusions drawn from this review suggest that omega-3 FAs in particular eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) found principally in oily fish have potent anti-angiogenic effects inhibiting production of many important angiogenic mediators namely; Vascular Endothelial Growth Factor (VEGF), Platelet-Derived Growth Factor (PDGF), Platelet-Derived Endothelial Cell Growth Factor (PDECGF), cyclo-oxygenase 2 (COX-2), prostaglandin-E2 (PGE2), nitric oxide, Nuclear Factor Kappa Beta (NFKB), matrix metalloproteinases and beta-catenin

Because of their health-promoting abilities, omega-3 fatty acids have received recognition from some of the top medical organizations in the world including, the American Heart Association, American Diabetes Association, World Health Organization, United Kingdom Scientific Advisory Committee on Nutrition, European Society for Cardiology, and The British Nutrition Foundation.

Benefits of Krill oil. It contains DHA, EPA, omega-3 fatty acids. Reduces risk of high blood pressure, heart attack, blood sugar levels and cardiovascular diseases

Children need omega-3 fatty acids (eicosapentaenoic acid/EPA and docosahexaenoic acid / DHA) for their brain development. Here is list of foods that act as brain foods

Does having enough sunlight and vitamin D give us more power to tolerate gluten and not develop damaging self-destructive auto-antibodies? It's unlikely we'll know in any good RCT (randomized controlled trials). No drug company will put up lettuce $$ to determine that good ol' cheap FREE UVB unblocked-sunshine is going to trump their $2-3/day drug (or super-sized vitamin D analogue) in a head-to-head trial. That's just absurd. And they're not stupid... because they pay staticians a lot of lettuce to figure that out for them.

"July 9, 2008 | Michael O'Riordan Boston, MA - The consumption of a diet containing vegetable oils rich in alpha-linolenic acid (ALA) is associated with significant reductions in the risk of nonfatal MI, a new study has shown [1]. Investigators say the protective effect of ALA is evident among individuals with low intakes, suggesting the greatest benefit might be in developing countries, where fatty-acid consumption is limited. "The potential for benefit is great when the baseline intake is low," said lead investigator Dr Hannia Campos (Harvard Medical School, Boston, MA). "In countries where people eat very little fish-and some of these countries have almost no sources of omega-3 fatty acids because they cook with corn or sunflower oils-the consumption of vegetable oils with ALA could have a major impact on heart disease." In an editorial accompanying the published study [2], Dr William Harris (University of South Dakota, Sioux Falls) said that the data are suggestive and would be good news for individuals who will not or cannot eat fish, but more studies are still needed. "If ALA were able to do the same 'heavy lifting' that [eicosapentaenoic acid] EPA and [docosahexaenoic acid] DHA do, this would be welcomed news, because the capacity to produce ALA is essentially limitless, whereas there are only so many fish in the sea," he writes.
