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.
