Health benefits of legume consumption analysed

23 October 2012

People who suffer from type-2 diabetes can improve their glycaemic control by taking up a low-glycaemic index diet that includes a cup of legumes once a day.

This is according to research backed by the Saskatchewan Pulse Growers, which also led to the suggestion that the diet could reduce the risk factors for coronary heart disease.

In order to reach such conclusions, the research team randomised 121 people with type-2 diabetes onto one of two diets.

One focussed on a low-glycaemic index (GI) being given to patients while the other involved an eating habit, which increased their consumption of soluble fibre by eating wholewheat products.

Following three months on either of these diets, people in the low-GI group recorded a higher fall in their glycosylated haemoglobin values when compared to those in the other cluster.

Furthermore, a 0.8 percentage point drop in those in the low-GI group's coronary heart disease risk score was recorded.

The study's authors commented: "Legume consumption of approximately 190g per day (1 cup) seems to contribute usefully to a low-GI diet and reduce coronary heart disease risk through a reduction in blood pressure."
