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 prospective randomised trial to determine the efficacy of a low glycaemic index diet given in addition to healthy eating and weight loss advice in patients with coronary heart disease
Objective : Recent epidemiological and prospect i ve trial evidence suggests that consumption of a low glycaemic index ( LGI ) diet will reduce coronary risk . We hypothesise that introduction of an LGI diet will improve the metabolic profile of patients who have undergone coronary artery bypass grafting . Design : We conducted a r and omised parallel group trial comparing a  control group ( n=29 , age 61.8±9 y ) ,  who received currently advocated healthy eating dietary advice only , to an intervention group , who received healthy eating advice emphasising LGI carbohydrates ( n=26 , age 63.6±9.4 y ) over a 12-week period in free-living patients with coronary heart disease . Outcome measures included fasting glucose , insulin , total cholesterol , high-density lipoprotein cholesterol , very low-density lipoprotein cholesterol , low density lipoprotein cholesterol and triglycerides . Results : A significant lower dietary glycaemic index was achieved in the group assigned to an LGI diet compared to the healthy eating control group ( 71±1 vs 81±1 ) ; fibre intake was also higher in the LGI group ( 20±1 vs 15±1 g ) . All biochemical markers of glucose and lipid metabolism measured were similar after 12 weeks of the LGI diet or control diet . Discussion : The LGI group achieved a significant LGI and a higher dietary fibre intake . However , there was no measurable significant effect of either the LGI diet or the health eating diet on lipid levels ; this may have been hidden by concurrent drug therapy
