Filling yet fattening: stereotypical beliefs about the weight gain potential and satiation of foods.

摘要

To what extent are stereotypes concerning the weight-gain potential and perceived hunger satisfaction of food names not congruent with views of the nutrient profiles of those same foods? Respondents rated the same 22 food names and descriptions in terms of weight-gain potential and hunger satisfaction. Half of the 22 snacks included foods from the lower two tiers of the USDA Food Guide Pyramid (fruits, vegetables, and grains: FV&G) and the other half from the upper two tiers (meats, dairy, fats, and sweets: MDF&S). FV&G and MDF&S snack names and descriptions were paired for data analyses based on energy content. Name and description ratings for weight-gain potential were not correlated, while these ratings for hunger satisfaction were strongly correlated. For weight-gain potential, fat and fiber content predicted snack-name ratings, while energy and sugar content predicted description ratings. For perceived hunger satisfaction, protein content predicted snack name ratings while energy and fat content predicted description ratings. The MDF&S snack named in each pair was always considered a greater weight gain promoter compared to its corresponding FV&G snack named. However, the description of the FV&G snack in each pair was often judged to promote greater weight-gain than the description of its corresponding MDF&S snack. Also, MDF&S names were generally judged as more filling than FV&G foods named with similar calorie content; however, a trend in the opposite direction was evident when rating the nutrient descriptions of these same foods. Apparently, food names have acquired reputation for promoting obesity and (to a lesser extent) hunger satisfaction that are not based on their nutrient profiles.
