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 .
A randomized clinical trial comparing low-glycemic index versus ADA dietary education among individuals with type 2 diabetes.
OBJECTIVE We compared the effects of a low glycemic index ( GI ) diet with the American Diabetes Association ( ADA ) diet on glycosylated hemoglobin ( HbA1c ) among individuals with type 2 diabetes . METHODS Forty individuals with poorly controlled type 2 diabetes were r and omized to a low-GI or an ADA diet . The intervention , consisting of eight educational sessions ( monthly for the first 6 mo and then at months 8 and 10 ) , focused on a low-GI or an ADA diet .  Data on demographics , diet , physical activity , psychosocial factors , and diabetes medication use were assessed at baseline and 6 and 12 mo . Generalized linear mixed models were used to compare the two groups on HbA1c , diabetic medication use , blood lipids , weight , diet , and physical activity .  RESULTS Participants ( 53 % female , mean age 53.5 y ) were predominantly white with a mean body mass index of 35.8 kg/m(2 ) . Although both interventions achieved similar reductions in mean HbA1c at 6 mo and 12 mo , the low-GI diet group was less likely to add or increase dosage of diabetic medications ( odds ratio 0.26 , P = 0.01 ) . Improvements in high-density lipoprotein cholesterol , triacylglycerols , and weight loss were similar between groups . CONCLUSION Compared with the ADA diet , the low-GI diet achieved equivalent control of HbA1c using less diabetic medication . Despite its limited size , this trial suggests that a low-GI diet is a viable alternative to the ADA diet . Findings should be evaluated in a larger r and omized controlled trial
