Abstract
The ubiquity of television in American culture makes it a potential
contributor to the obesogenic (obesity-causing) environment. Televised food
advertisements, which encourage viewers to eat the foods promoted for sale,
constitute a de facto set of dietary endorsements. The purpose of this study
was to compare the nutritional content of food choices endorsed on television
to nutritional guidelines. Using a cross-sectional design, food advertisements
were observed during 84 hours of primetime and 12 hours of Saturday-morning
televised broadcast during the fall of 2004. One-sample t tests were used to
compare the food group servings of observed food items to the recommended daily
servings and to compare the nutrient content of observed food items to the
Daily Values. Results suggest that a diet consisting of observed food items
would provide 2,560% of the recommended daily servings for sugars, 2,080% of
the recommended daily servings for fat, 40% of the recommended daily servings
for vegetables, 32% of the recommended daily servings for dairy, and 27% of the
recommended daily servings for fruits. The same diet would substantially
oversupply protein, total fat, saturated fat, cholesterol, and sodium, while
substantially undersupplying carbohydrates, fiber, vitamins A, E, and D,
pantothenic acid, iron, phosphorous, calcium, magnesium, copper, and potassium.
Overall, the food choices endorsed on television fail to meet nutrition
guidelines and encourage nutritional imbalance. 2010 American Dietetic
