Eating Fish or Taking Fish Oils to Prevent Alzheimer’s Disease and Dementia
An Editorial in the AMA journal summarized the limited evidence and concluded that it is indeed beneficial to increase fish intake to slow the progression of various neurogenic diseases such as Alzheimer’s disease and Parkinson’s disease. The benefit exceeded the risk of eating fish, much of which is contaminated with mercury. My advice is to be as sure as possible that your source of fish oil has been tested for the absence of mercury. Further, a simple challenge test for mercury accumulating in the body should be done at least every 2-3 years for fish-eaters. If the level is high, chelation can bring much of the mercury out of the body and brain. This should increase the benefit of eating fish substantially.
