Conclusions /interpretationPooled analyses demonstrated that pulses , alone or in low-GI or high-fibre diets , improve markers of longer term glycaemic control in humans , with the extent of the improvements subject to significant inter- study heterogeneity .
Aims /hypothesisDietary non-oil-seed pulses ( chickpeas , beans , peas , lentils , etc . )
are a good source of slowly digestible carbohydrate , fibre and vegetable protein and a valuable means of lowering the glycaemic-index ( GI ) of the diet .
To assess the evidence that dietary pulses may benefit glycaemic control , we conducted a systematic review and meta- analysis of r and omised controlled experimental trials investigating the effect of pulses , alone or as part of low-GI or high-fibre diets , on markers of glycaemic control in people with and without diabetes .
Effects of long-term consumption and single meals of chickpeas on plasma glucose, insulin, and triacylglycerol concentrations.
BACKGROUND Legumes are recommended for better glucose control in persons with diabetes . Whether subjects with normal insulin sensitivity would also benefit from legume consumption is not clear . OBJECTIVE Our goal was to compare the effects on insulin sensitivity of chickpea-based and wheat-based foods when eaten as single meals or over 6 wk . DESIGN Acute and long-term studies were conducted in healthy middle-aged men and women . In the acute study ( n = 19 ) , plasma glucose , insulin , and calculated homeostasis model assessment ( HOMA ; an index of insulin sensitivity ) were measured on 3 separated days over 3 h after the subjects consumed 50-g available carbohydrate loads from either chickpeas , wheat-based foods , or white bread . The long-term comparison ( n = 20 ) was a r and omized , crossover study in which chickpea-based and wheat-based foods were eaten for 6 wk each . Plasma glucose , insulin , and HOMA were measured in the fasting state and 2 h after a 75-g glucose load . RESULTS After single meals , plasma glucose was substantially lower 30 and 60 min after the chickpea meal than after the other 2 meals ( P < 0.05 ) , and plasma insulin and HOMA were lower at 120 min ( P < 0.05 for both ) . Despite this , the long-term study failed to show significant differences in plasma glucose , insulin , or HOMA either in the fasting state or after a glucose load . CONCLUSION Compared with a wheat-based meal , a single chickpea-based meal led to a lesser response in plasma glucose and insulin concentrations , but this was not translated into long-term improvement in insulin sensitivity over 6 wk , at least in healthy subjects
