A new study advises against following the recommendations of television commercials when it comes to deciding what to eat.

The study published in the June issue of the Journal of the American Dietetic Association found that a 2,000-calorie diet consisting entirely of advertised foods would contain 25 times the recommended servings of sugars and 20 times the recommended servings of fat, but less than half of the recommended servings of vegetables, dairy, and fruits.

Researchers analyzed 96 hours of television programming to identify food advertisements and specific food items being promoted. Each food item advertised was then analyzed for nutritional content.

The findings indicated that the featured items fail to comply with Food Guide Pyramid recommendations in every food group except grains. The average observed food item contained excessive servings of sugars, fat, and meat and inadequate servings of dairy, fruit and vegetables.

Lead researcher Michael Mink, Ph.D. said that the results suggest the foods advertised on television tend to oversupply nutrients associated with chronic illness such as saturated fat, cholesterol, and sodium and undersupply nutrients that help protect against illness such as fiber, vitamins A, E, and D, calcium, and potassium.
