Human body needs to convert carbohydrates into glucose. Whole grains have rich carbohydrates, which is an important nutrition source. Whole grains also contain plenty fiber, vitamins and minerals (such as riboflavin, thiamin, niacin, phosphorus, magnesium, selenium, iron and zinc). These nutrients can help to reduce blood pressure and improve heart health. Whole grains also supply B vitamins and iron, as well as other beneficial phytonutrients. Your diet can add whole-wheat foods, such as high-fiber cereals.
Flaxseed can also be a healthy choice, it helps to reduce blood cholesterol because it contains high fiber and omega-3 fatty acids.
