Eat Fish? There's a catch...

Eat more fish! But not too much fish. And not the wrong kind of fish.

Eating plenty of fish, nuts and oil-based salad dressings that contain polyunsaturated fatty acids cuts the risk of developing Alzheimer's disease, researchers said on Monday.

A seven-year study of 815 nursing home residents -- 131 of whom developed the brain-robbing disease -- found those who reported eating fish at least once a week had a 60 percent lower risk of Alzheimer's compared to those who rarely or never ate fish.

But be wary.... too much of the wrong kind of fish can lead to memory loss and other health problems! Large predator fish (some of the tastiest fish) such as tuna, halibut, swordfish, red snapper, flounder, and freshwater bass, have on occasion shown unsafe levels of mercury. Dr. Jane Hightower, an internal medicine specialist in San Francisco, found that eating 'too much of the wrong kind of fish can give you a nasty case of mercury poisoning".

Dr. Hightower's conclusions are discussed in the August issue of Reader's Digest and the April issue of ELLE Magazine (summarized at HealthNewsDigest.com) and elsewhere (MSNBC News, LA Times article, SF Chronicle article).

The Reader's Digest article (August 2003 issue) recommends no more than 2 meals per month of the worst offenders; pregnant women, nursing mothers, and children under 8 should avoid these fish altogether.
