SFA, saturated fatty acid; PUFA, polyunsaturated fatty acid; MUFA, monounsaturated fatty acids. The data have been expressed as mean ± SD. P1: between-group comparison of the variables; independent sample t-test (for energy and dietary protein, fat, PUFA, MUFA, and SFA) and Mann–Whitney U test (for dietary carbohydrate). P2: within-group comparison of the variables; paired sample t-test (for energy and dietary protein, fat, PUFA, MUFA, and SFA intake) and Wilcoxon signed-rank test (for dietary carbohydrate)
