Brain food

The adage "you are what you eat" applies not just to heart, muscle and bones, but to the brain as well, says G. Harvey Anderson, a nutrition researcher at the University of Toronto. "Diet can have a profound effect on behavior," he said at the recent Bristol-Myers press symposium in Washington, D.C., on nutrition.

Working in his laboratory, Carol Leprohon-Greenwood found that rats fed a diet high in polyunsaturated fats learned more quickly than rats eating saturated fat.

Anderson speculates that when nerve cells use saturated fats in their membranes, the membranes become less flexible. The more rigid membranes may distort the receptors for the neurotransmitters that control cell-to-cell communication, making them less sensitive. Whether humans can improve their mental performance by cutting down on saturated fat "we just don't know," says Anderson.
