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 .
Rate of digestion of foods and postprandial glycaemia in normal and diabetic subjects.
Carbohydrate portions ( 2 g ) of lentils , soya beans , and wholemeal bread were incubated for three hours with human digestive juices and the effect of digestibility on blood glucose examined . Lentils and soya beans released only 39 % and 8 % respectively of the sugars and oligosaccharides liberated from bread . In healthy volunteers 50 g carbohydrate portions of cooked lentils and soya beans raised blood glucose concentrations by only 42 % ( p < 0.001 ) and 14 % ( p < 0.001 ) of the bread value . There was a similar response in diabetics . These results suggest that rate of digestion might be a important factor determining the rise in blood glucose concentration after a meal and that supplementing chemical analysis with in-vitro and in-vivo food testing might permit identification of especially useful foods for diabetics
