Table 3.
Number of servings (mean (SEM)) from food groups and selected foods within the groups. Only selected foods with at least 0.1 servings at any time period were included in the table. Comparisons were made between each time point using repeated measures of covariance. Values with different letters are statistically significantly different from each other (p<0.05).
