Pleanty of evidence already out there on the benefits of eating oily fish and using Omega-3 Supplements. Another story out this week says:
"In Alzheimer's disease, lesions known as "plaques" and "tangles" form in the brain, due to the abnormal clumping of two proteins called beta-amyloid and tau. The mouse study found that a diet rich in the fatty acid DHA might interfere with this process"
"The researchers also discovered that DHA may confer its benefit by lowering levels of an enzyme needed to generate beta-amyloid."
I have always been a big believer in fish oils and offer several molecularly distilled products:
EPA/DHA w/Olive and Sesame Lignans (LEF)
Nordic Naturals Ultimate Omega
Nordic Naturals EPA
Max DHA (AOR)
Salmon Essentials with Astaxanthin (Mera Pharmaceuticals, one of my favorites)
