A vegan diet improves beta-cell function, according to a study published in Nutrients. Researchers from the Physicians Committee assessed insulin resistance after a meal for 75 overweight participants without diabetes for 16 weeks, half of whom followed a low-fat, vegan diet. Those who consumed the vegan diet increased meal-stimulated insulin secretion and beta-cell glucose sensitivity and lowered their body weight, compared with the control group. Lower body fat increases beta-cells’ ability to regulate blood sugar. These results show that a vegan dietary intervention helps prevent diabetes.
