Nutrition knowledge among adolescent high school female athletes.

The purpose of this study is to evaluate the effectiveness of an original sports nutrition education program in changing the nutrition behavior of the female high school varsity football teams of the Baseline League of Southern California. A total of 72 subjects from eight teams were randomly divided into two groups, control and experimental. Only the experimental group received nutrition education. Dietary habits of the athletes were studied through a pre- and post- 24-hour recall. A comparison of pretest scores of both groups showed no significant difference in level of nutrition knowledge. The posttest scores obtained after nutrition education showed a significant difference in nutrition knowledge for the experimental group. However, there was no significant improvement in dietary intake and food choices due to the limited duration of the study.

Color preference and food choice among children.

The effects of color on children's food choices were investigated. Subjects were 120 children who were equally distributed among each of the combinations of age (5 vs. 9 years old), sex (male vs. female), food type (3 types of candies), and color (red, green, yellow, and orange) in a counterbalanced, factorial, analysis-of-variance design with repeated measures on subjects. A significant main effect for color indicated that children preferred foods that were red, green, orange, and yellow, in that order. Interpretation of this main effect was not interfered with by main effects or interaction terms involving age, sex, or food type, which served as alternative rival hypotheses.
