Food for Thought

From the many studies in recent years that have linked diet to cognitive function, scientists are slowly putting together a list of foods that seem to have particular influence on the health of the brain.

Studies have shown improvements in memory, IQ, concentration and mood; others have shown a reduced risk of cognitive decline, dementia and Alzheimer's disease. Remember to eat these foods and you'll be more likely to remember everything else.

blueberries

strawberries

canola oil

wheat germ

Whole grains:

barley

Foods rich in folic acid:

One-Two Punch for Alzheimer's

A recent study of 4,740 elderly people linked the combination of vitamin C and E supplements with a 60 percent reduced risk of Alzheimer's disease. The benefits appeared in people who were taking daily supplements containing about 400 IU of vitamin E and 500 mg of vitamin C.

Why would these two work only in combination? Epidemiologist Peter Zandi at the Johns Hopkins Bloomberg School of Public Health says that fat-soluble vitamin E "stays around in the body for a relatively long time," while water-soluble vitamin C is rapidly excreted. Zandi speculates that "vitamin C may serve primarily to recharge the antioxidant capacities of the vitamin E that is in the body."
