Consumption of vegetarian diets is associated with improved glycemic control in type 2 diabetes .
INTRODUCTION Previous studies have suggested an association between vegetarian diets and improvements in glycemic control in diabetes , although this relationship is not well established .
No meta- analysis of these studies has been performed .

Effectiveness of a low-fat vegetarian diet in altering serum lipids in healthy premenopausal women.
Few controlled trials have studied cholesterol-lowering diets in premenopausal women . None has examined the cholesterol-lowering effect of a low-fat vegetarian diet , which , in other population groups , leads to marked reductions in serum cholesterol concentrations and , in combination with other life-style changes , a regression of atherosclerosis . We tested the hypothesis that a low-fat , vegetarian diet significantly reduces serum total and low-density lipoprotein ( LDL ) cholesterol concentrations in premenopausal women . In a crossover design , 35 women , aged 22 to 48 , followed a low-fat vegetarian diet deriving approximately 10 % of energy from fat for 2 menstrual cycles . For 2 additional cycles , they followed their customary diet while also taking a " supplement " ( placebo ) pill .  Serum lipid concentrations were assessed at baseline and during each intervention phase . Mean serum LDL , high-density lipoprotein ( HDL ) , and total cholesterol concentrations decreased 16 . 9 % , 16.5 % , and 13.2 % , respectively , from baseline to the intervention diet phase ( p<0.001 ) , whereas mean serum triacylglycerol concentration increased 18.7 % ( p<0.01 ) . LDL/HDL ratio remained unchanged . Thus , in healthy premenopausal women , a low-fat vegetarian diet led to rapid and sizable reductions in serum total , LDL , and HDL cholesterol concentrations
