Pooled analyses showed that oat β-glucan has a lowering effect on LDL-cholesterol , non-HDL-cholesterol and apoB. Inclusion of oat-containing foods may be a strategy for achieving targets in CVD reduction
Oats are a rich source of β-glucan , a viscous , soluble fibre recognised for its cholesterol-lowering properties , and are associated with reduced risk of CVD .
Our objective was to conduct a systematic review and meta- analysis of r and omised-controlled trials ( RCT ) investigating the cholesterol-lowering potential of oat β-glucan on LDL-cholesterol , non-HDL-cholesterol and apoB for the risk reduction of CVD .
Four-week low-glycemic index breakfast with a modest amount of soluble fibers in type 2 diabetic men.
Low-glycemic index diets are associated with a wide range of benefits when followed on a chronic basis . The chronic effects , however , of the substitution of 1 meal per day are not well known in diabetic subjects . Therefore , we aim ed to evaluate whether the chronic use of a low-glycemic index breakfast ( low-GIB ) rich in low-GI carbohydrates and a modest amount of soluble fibers could have an effect on lipemia at a subsequent lunch , and improve glucose and lipid metabolism in men with type 2 diabetes . A total of 13 men with type 2 diabetes were r and omly allocated in a double-blind cross-over design to a 4-week daily intake of a low-GI versus a high-GI breakfast separated by a 15-day washout interval . The low-GI breakfast was composed of whole grain bread and muesli containing 3 g beta-glucan from oats . Low-GIB induced lower postpr and ial plasma glucose peaks than the high-GIB at the beginning ( baseline , P < .001 ) and after the 4-week intake ( P < .001 ) . The incremental area under the plasma glucose curve was also lower ( P < .001 , P < .01 , baseline , and 4 weeks , respectively ) . There was no effect on fasting plasma glucose , insulin , fructosamine , or glycosylated hemoglobin ( HbA(1c ) ) . Fasting plasma cholesterol , as well as the incremental area under the cholesterol curve , were lower ( P < .03 , P < .02 ) after the 4-week low-GIB period than after the high-GIB period . Apolipoprotein B ( apo B ) was also decreased by the 4-week low-GIB . There was no effect of the low-GI breakfast on triacylglycerol excursions or glucose and insulin responses at the second meal . The high-GIB , however , tended to decrease the amount of mRNA of leptin in abdominal adipose tissue , but had no effect on peroxisome proliferator-activated receptor gamma ( PPARgamma ) and cholesterylester transfer protein ( CETP ) mRNA amounts . In conclusion , the intake of a low-GI breakfast containing a modest amount ( 3 g ) of beta-glucan for 4 weeks allowed good glycemic control and induced low plasma cholesterol levels in men with type 2 diabetes . The decrease in plasma cholesterol associated with low-GI breakfast intake may reduce the risk of developing cardiovascular complications in subjects with type 2 diabetes
