How Fish Oil Fights Alzheimer's

There's no doubt fish oil -- chock full of omega-3 fatty acids -- is a highly effective weapon you can use to protect your health from the ravages of Alzheimer's disease. A new study by scientists at Louisiana State University (free text link below) has discovered how those omega-3 fats work to protect your brain from cognitive decline.

Docosahexaenoic acid (DHA) -- the most important of the omega-3 fats -- lowers the levels of a protein that creates damaging plaques in the brains of Alzheimer's patients.

Researchers compared the brains of Alzheimer's victims with those who didn't suffer from that mind-robbing disease, by testing postmortem tissue samples with tandem mass spectrometry that analyzed changes in brain cells.

Not only does the DHA you consume via fish oil protect your body from Alzheimer's by reducing amount of beta amyloids, scientists also discovered the presence of a natural substance made by the brain -- a DHA derivative called neuroprotectin D1 (NPD1) -- that prevents cell death. In fact, Alzheimer's patients were found to have 20-25 times less NPD1 in some areas of their brains than those not stricken with the disease.

By the way, consuming a high quality fish or cod liver oil daily is only one of many things you can do to lower your risk of Alzheimer's easily and inexpensively.
