ADVISORY/Debate Over Food Guidelines Heats Up

(BUSINESS WIRE)--July 26, 2001--

TOPIC: The chairman of the department of nutrition at Harvard School of Public Health, Walter Willet, has written a new book called ``Eat, Drink and Be Healthy: The Harvard Medical School Guide to Healthy Eating,'' that reportedly criticizes the USDA food pyramid and has ignited another flare up in the debate over American nutritional guidelines. According to a story by USA Today, opponents of the food pyramid -- which advises eating six to 11 servings of bread, cereal, rice and pasta a day; two to three servings of meat, poultry, fish, dry beans, eggs and nuts; and fats, oils and sweets sparingly -- claim it is too general, puts too much stress on carbohydrates and may contribute to obesity and poor health. Proponents of the pyramid cited in the story say that the general guidelines are simple enough for everyone to use and understand, work better than a completely unrestricted diet, and serve the population better than other untested fads and guidelines.
