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 .
Slow release dietary carbohydrate improves second meal tolerance.
Breakfasts of lentils or wholemeal bread of identical carbohydrate content were taken by seven healthy volunteers . The lentils produced a significant 71 % ( p less than 0.001 ) reduction in the blood glucose area and flattened the plasma insulin and gastric inhibitory polypeptide responses by comparison with the bread . In addition , the lentil breakfast was followed by a significantly flatter blood glucose response to the st and ard bread lunch which followed 4 h later ( by 38 % , p less than 0.01 ) . The blood glucose pattern was mimicked by feeding the bread breakfast slowly over the 4 h before lunch . Giving a bread breakfast containing a quarter of the carbohydrate reduced the breakfast glucose profile but result ed in a significantly impaired blood glucose response to lunch ( 168 % of control , p less than 0.01 ) . These results , together with breath hydrogen studies , performed on a separate group of four volunteers , indicate that the flattened response to lentils is not due to carbohydrate malabsorption . Slow release or " lente " carbohydrate foods such as lentils may form a useful part of the diets of those with impaired carbohydrate tolerance
