Lentils significantly reduce blood glucose levels, study reveals


“Canada has a huge production of lentils, but we export most of it and only 13 per cent of Canadians eat them on any given day,” said Duncan. “We are hoping this research will make people more aware of the health benefits of eating pulses.”


Published and specially featured in the Journal of Nutrition, the study involved 24 healthy adults fed four dishes—white rice only, half white rice and half large green lentils, half white rice and half small green lentils, and half white rice and half split red lentils.


Researchers measured glucose levels in the participants’ blood before they ate and during two hours afterward. They repeated the process for white potatoes alone and the same combinations of potatoes and lentils.


“We mixed the lentils in with the potatoes and because people don’t typically eat pulses on their own, but rather consume them in combination with other starches as part of a larger meal, so we wanted the results to reflect that.”
