In a randomized controlled trial, patients who ate at least an additional cup of legumes per day had a greater reduction in HbA1c than patients who increased their insoluble fiber consumption for 3 months as per David Jenkins, MD, PhD, of the University of Toronto in the Archives of Internal Medicine.The diet significantly lowered mean total cholesterol and triglycerides, without any changes in HDL cholesterol levels.
