Effect of oats, tartary buckwheat, and foxtail millet supplementation on serum TG (A), TC (B), HDL-C (C), LDL-C (D), and FFA (E) in high-fat diet fed rats. Con group, a basal diet group; HFD group, a high-fat diet group; Oat group, HFD containing 22% oat group; Buc group, HFD containing 22% tartary buckwheat group; Mil group, HFD containing 22% foxtail millet group; TG, total triglyceride; TC, total cholesterol; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; FFA, free fatty acid. Data are presented as the mean ± SD (n = 12). # p < 0.05, compared to Con group, * p < 0.05, compared to HFD group.
