High glycemic foods are often are often lower in fiber and more highly refined and includes white bread, pasta made of white flour, doughnuts, ice cream and bananas. These have adverse effects on the heart health. High carbohydrate intake increases the levels of blood glucose and of harmful blood fats known as triglycerides.
