2007-04-26 Omega-3 may fight Alzheimer brain changes


(Reuters Health) - A fatty acid found in fish may help thwart the buildup of brain proteins linked to Alzheimer's disease, a study in mice suggests.

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.

DHA, short for docosahexaenoic acid, is a type of omega-3 fatty acid found mainly in fatty fish like salmon and mackerel, and to a lesser extent in seaweed, eggs, organ meats and DHA-fortified foods.(Read entire article)

2007-04-17 Omega-3 Fatty Acid May Thwart Alzheimer's Disease


A type of omega-3 fatty acid called docosahexaenoic acid (DHA) may help slow the growth of two kinds of brain lesions associated with Alzheimer's disease, a new study suggests.

The researchers at the University of California, Irvine, said their finding suggests that a diet rich in DHA -- found in fish, eggs, organ meats, micro-algae, fortified foods and food supplements -- may help prevent the development of Alzheimer's as people age.

In this study with genetically modified mice, the scientists found that DHA slowed accumulation of tau, a protein that leads to the development of neurofibrillary tangles, one of the two signature brain lesions of Alzheimer's. (Read entire article)
