St. Louis, MO, June 1, 2010 Making food choices based on television advertising results in a very imbalanced diet according to a new study comparing the nutritional content of food choices influenced by television to nutritional guidelines published in the June issue of the Journal of the American Dietetic Association.
Investigators 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. In fact, the excess of servings in sugars and fat is so large that, on average, eating just one of the observed food items would provide more than three times the recommended daily servings (RDS) for sugars and two and a half times the RDS for fat for the entire day.
"The results of this study suggest the foods advertised on television tend to oversupply nutrients associated with chronic illness (eg, saturated fat, cholesterol, and sodium) and undersupply nutrients that help protect against illness (eg, fiber, vitamins A, E, and D, calcium, and potassium)," according to lead investigator Michael Mink, PhD, Assistant Professor and MPH Program Coordinator, Armstrong Atlantic State University, Savannah, GA.
Researchers analyzed 84 hours of primetime and 12 hours of Saturday morning broadcast television over a 28-day period in 2004. ABC, CBS, Fox and NBC were sampled on a rotating basis to develop a complete profile of each network. The Saturday-morning cartoon segment (from 8:00 am to 11:00 am) was included to capture food advertisements marketed primarily to children.
All 96 hours of observations were videotaped and reviewed later to identify food advertisements and specific food items being promoted. Only food items that were clearly promoted for sale during an advertisement were recorded. Each food item was then analyzed for nutritiona
