Green Beans are full of fiber, which is an important nutrient for many reasons. Soluble fiber, in particular, may help to improve the health of your heart by lowering your LDL cholesterol (bad cholesterol) levels. The fiber in green beans helps to keep your digestive system healthy and running smoothly. Many studies have suggested that including more plant foods, such as green beans, in the diet decreases the risk of obesity, diabetes, heart disease, and overall mortality. Consumption of fruit and vegetables also promotes a healthy complexion, increased energy, and overall lower weight.
