Omega-3 Fatty Acids in Fish Oil May Fight Cancer and Improve Old Age Cognition
Published in the “Journal of Nutrition,” (December 2004 issue) the authors indicated their review showed that consumption of omega-3 fatty acids has been shown to slow progression of cancers of the lung, colon, breast and prostate….and in humans, omega-3 fatty acids have been used to suppress cancer-associated physical wasting and malnutrition and to improve quality of life. “The authors concluded that in combination with standard treatments, consumption of omega-3 fatty acids may provide a nontoxic means to improve cancer treatment outcomes and may slow or prevent recurrence of cancer; they added omega-3 supplementation may constitute a useful alternative therapy for patients who are not candidates for standards toxic cancer therapies.” (Journal of Nutrition (134, 12: 3427S-3430S, 2004)).
In another observational study published in the “American Journal of Clinical Nutrition,” (December 2004) scientists examined the effects of food supplement on cognitive aging on subjects born in 1936, were tested for mental ability in 1947. The same subjects were followed up in 2000 and 2001 at which time cognition, diet, food supplement use, and risk factors for vascular disease were assessed. Fish oil users were matched with nonusers, and cognitive function was related to erythrocyte omega-3 essential fatty acid (EFA) composition. The scientists found that the subjects, at the age of 64 years, had cognitive function higher in the food supplement users than in nonusers before adjustment for childhood IQ. After adjustment for childhood IQ, digit symbol (mental speed) test scores also were higher in food supplement users. Fish oil supplement users were also found to have consumed more vitamin C and vegetable and cereal fiber than did nonsupplement users. “The scientists concluded, omega-3 supplement use is associated with better cognitive aging. If associations with omega 3 content are causal, optimization of omega 3 and omega 6 fatty acid intakes could improve retention of cognitive function in old age.” (American Journal of Clinical Nutrition (80, 6:1650-1657, 2004))

Australian researchers reviewed 9 published studies and concluded that eating fish twice a week reduced the risk of early and late AMD – Age-related Macular Degeneration. The studies included over 3,000 people with AMD and found that a diet high in intake of omega-3 fatty acids was correlated with a 38% reduced risk of AMD.
Outer cells of the retina are continually shed and regenerated. With a sufficient dietary intake, the [long-chain] omega-3 fatty acids were found to be integral in the formation of the layer of nerve cells in the retina. The researchers tempered their results by stating the consumption of foods rich in omega-3 fatty acids may be associated with a lower risk of AMD, but there is currently insufficient literature, prospective studies and randomized trials to support an unqualified conclusion and recommendations.

So here’s to health.
There are 4 predominant factors that contribute to chronic and degenerative disease, esp. as we age: (1) Free Radical Damage; (2) Chronic Inflammation; (3) Hyperinsulemia; and, (4) Stress (excess or diminished cortisol). Optimal health is proactively working to prevent all four.
To maintain health and improve with age we focus on five areas: (1) The power of positive mental thinking and focus (there really is a power of attraction so be positive and attract the positive); (2) Regular exercise for all its’ known benefits; (3) A diet rich in whole foods (not processed) and especially dark-colored fruits and vegetables known to be rich in antioxidants; (4) Taking time to get your restorative sleep each day/night; and, (5) Supplements.
What supplements do you take? And how often?
