Abstract

A 2 x 2 factorial arrangement of treatments was used to test the hypothesis that inclusion of a novel P-glucan extract (GlucagelTM) in cholesterol-free synthetic diets containing coconut oil or flax oil would lower circulating total cholesterol (TC) and triglyceride (TG) levels in growing rats. Inclusion of Glucagel™ (100 g/kg) tended to decrease TC levels (P=0.07), however TC level was not influenced by oil type (P>0.05). A significant interaction (P<0.05) occurred for TG levels, with the addition of p-glucan to diets containing coconut oil and flax oil decreasing TG levels by 40% (P<0.01) and 13% (P>0.05), respectively. Faecal digestibility of fat was reduced by 7% (P=0.08) in rats fed coconut oil plus P-glucan. These data suggest that reduced TG levels caused by addition of p-glucan may be mediated in part by reduced fat digestion in the small intestine, an effect most likely caused by the unique gel-forming properties of Glucagel™
