This research compared nutrient intake data with blood lipids and anthropometric data. Height, weight, and seven skinfolds were collected 3 days prior to competition at the official weigh-in. The lipids measured were total cholesterol (TC), HDL-cholesterol (HDL-C), and the HDL2 and HDL3 cholesterol subfractions. The subjects were 17 males and 17 females. Descriptive data are presented as means and standard deviations of the means. Protein, fat, and carbohydrate provided about 40, 12, and 48%, respectively, of total energy intake; vitamin C was >200 mgfday. Only dietary fat was significantly (p < 0.05) associated with TC for females. Fiber was significantly associated with HDL-C and HDL2-C for males and with HDL-C for females. Vitamin C was significantly associated with HDL-C, HDL2-C, and HDL3-C for males, and with HDL-C and HDL3-C for females. These findings are consistent with those reported by Bazzarre et al. in farmers and suggest that vitamin C may favorably influence HDL-C metabolism.
