Food for thought: The relationship between eating behaviors and brain responses to food presentation
Because diet and nutrition are vital aspects of healthy human beings, scientists have begun studying the brain's potential influence and role in formulating a healthy diet and curbing obesity. In a study from the U.S. Department of Energy's Brookhaven National Laboratory in Upton, N.Y., researchers assessed the effects of food presentation on the brain. The study could help researchers assess the root, chemical causes of eating disorders and obesity. more
