Omega 3 oils prevent Alzheimer’s plaques
New research of 1,219 cognitively healthy elderly (age >65 years) has shown consumption of Omega 3 oils is associated with a reduction of plasma beta amyloid plaques (Y. Gu). The protein, plasma beta amyloid plaques, have been associated with Alzheimer’s disease. The study reported that one gram increase of Omega 3 oils above the normal consumption was associated with a reduction of 20-30% of the plasma beta amyloid plaques.
This builds on a comprehensive list of both animal and human studies which show a reduction of Alzheimer’s with increased omega 3 consumption. According to a 2005 U.S. Department of Health and Human Services meta‑analysis that reviewed 497 studies, high EPA and DHA consumption may help ward off Alzheimer's disease and dementia. In another study of adults aged 65-94, those who ate fish at least once a week had a 60 per cent lower risk of developing the disease compared to those who never or rarely ate fish. A series of studies with biotech mice with Alzheimer disease indicated that deficiency in the omega-3 DHA hastened the development and severity of Alzheimer disease in these mice.
From these and many more studies researchers believe that a critical period of two years or more before the onset of dementia may therefore be critical for the anti-inflammatory effects of the omega-3s, a suggestion that boosts dietary guidelines to increase omega-3 fatty acid intake from dietary or supplemental sources. But don’t wait till you have the disease already as the Omega 3 oils have many, many other benefits
Recently I blogged on the benefits of Vitamin D for reducing Alzheimer’s and other work that shows Tumeric to also be effective in prevention. This calls for more Omega 3, Tumeric and more sunlight if you want to reduce your risk of Alzheimer’s.
