Protein-packed and rich in fibre, researchers have found another reason to eat lentils

(Laura Brehaut/ The Province) — They’re high in fibre, full of complex carbohydrates and 25 per cent protein. As a pantry staple, they’re inexpensive and versatile. And new research out of the University of Guelph has found yet another compelling reason to eat lentils: they can significantly lower blood sugar levels.

In a study published in the Journal of Nutrition, researchers discovered that making a simple swap in familiar starchy side dishes could have profound effects. Substituting half a serving of rice with lentils resulted in a 20 per cent drop in blood glucose, while the same substitution with potatoes showed a 35 per cent decrease.

“Pulses are extremely nutrient-dense food that have the potential to reduce chronic diseases associated with mismanaged glucose levels,” said Prof. Alison Duncan of the Department of Human Health and Nutritional Sciences, explaining that they can decelerate digestion and help stabilize sugars in the bloodstream.

“This slower absorption means you don’t experience a spike in glucose. Having high levels over a period of time can lead to mismanagement of blood glucose, which is the hallmark of Type 2 diabetes. Essentially, eating lentils can lower that risk.” (…)
