Study conducted in the University of Toronto has found out that eating pistachio could help you in lowering your blood sugar. Pistachio, when taken with high carbohydrate food items like white bread, slows down the absorption of carbohydrate in the body. It works towards prevention and control of diabetes by suppressing the glycemic (blood sugar) response of high carbohydrate foods. The mono-unsaturated fat in pistachio has been scientifically proven to help lower the bad cholesterol (LDL) and increase the good cholesterol (HDL) which protects the heart.
