The site offers the opportunity for individuals or groups to register to receive health tips and motivational information.

Nurses' Health Study

A study based on a survey of nurses that was started in 1976, by Dr. Frank Speizer. The second phase was founded in 1989 by Dr. Walter Willett of the Harvard School of Nutrition. The study tracks the health and dietary intake of its participants, and it is one of the only long-term studies that examines the connection between diet and health.

Analysis

Rebuilding the Food Pyramid

Harvard School of Public Health professors Walter Willett and Meir J. Stampfer explain why they feel the USDA's current food pyramid is flawed. They offer a revised pyramid, and write that "studies indicate that adherence to the recommendations in the revised pyramid can significantly reduce the risk of cardiovascular disease for both men and women." Their pyramid is also the basis for Willett's book, Eat, Drink, and Be Healthy. (Scientific American, Dec. 17, 2002)

"What If It's All Been a Big Fat Lie?"

Science writer Gary Taubes wrote this controversial story for New York Times Magazine, in which he explains why a diet that is high in fat and low in carbohydrates might be the answer to the nation's obesity problem. In response to public health recommendations he argues "We ate more fat-free carbohydrates, which, in turn, made us hungrier and then heavier. Put simply, if the alternative hypothesis is right, then a low-fat diet is not by definition a healthy diet. In practice, such a diet cannot help being high in carbohydrates, and that can lead to obesity, and perhaps even heart disease." (July 7, 2002)
