Conclusions : In summary , the use of ITF may have benefits for LDL-c reduction across all study population s , whereas HDL-c improvement and glucose control were demonstrated only in the T2DM subgroup .
Overall , ITF supplementation may provide a novel direction for improving the lipid profile and glucose metabolism
Addition of inulin to a moderately high-carbohydrate diet reduces hepatic lipogenesis and plasma triacylglycerol concentrations in humans.
BACKGROUND A high-carbohydrate , low-fat diet is recommended for the prevention of atherosclerosis , because it reduces plasma cholesterol concentrations . However , such a diet can increase plasma triacylglycerol concentrations -- an undesirable side effect . The addition of nondigestible carbohydrate could reduce the risk of elevated triacylglycerol concentrations . OBJECTIVE The objective was to determine whether the addition of a moderate dose of inulin to a moderately high-carbohydrate diet would decrease hepatic lipogenesis and plasma triacylglycerol concentrations and have a cholesterol-lowering action . DESIGN Eight healthy subjects were studied twice in a double-blind , r and omized , placebo-controlled crossover study after consuming for 3 wk a moderately high-carbohydrate , low-fat diet ( 55 % of total energy ) plus an oral placebo or 10 g high-performance inulin/d .  Hepatic lipogenesis and cholesterol synthesis ( deuterated water method ) , plasma lipid concentrations , fatty acid synthase , acetyl-CoA carboxylase 1 , and sterol responsive element binding protein 1c messenger RNA concentrations were measured in adipose tissue at the end of the 2 diet periods . RESULTS Plasma triacylglycerol concentrations and hepatic lipogenesis were lower after inulin than after placebo ingestion ( P < 0.05 ) , but cholesterol synthesis and plasma cholesterol concentrations were not significantly different between the 2 groups . None of the adipose tissue messenger RNA concentrations changed significantly after inulin ingestion . CONCLUSIONS The addition of high-performance inulin to a moderately high-carbohydrate , low-fat diet has a beneficial effect on plasma lipids by decreasing hepatic lipogenesis and plasma triacylglycerol concentrations . These results support the use of nondigestible carbohydrate for reducing risk factors for atherosclerosis
