Fresh green beans are very low in calories and contain no saturated fat. Nevertheless, the lean vegetables are a very good source of vitamins, minerals, and plant derived micronutrients.
Green beans are an excellent source of protein, complex carbohydrates and fiber. Their high fiber content aids digestion and the protein helps to regulate blood sugar levels.
They also contain good amounts of vitamin-B6 (pyridoxine), thiamin (vitamin B-1), and vitamin-C. Consumption of foods rich in vitamin C helps the body develop resistance against infectious agents and scavenge harmful oxygen-free radicals.
The folic acid and B6 in green beans make them a “heart healthy” vegetable as well because it lowers an amino acid called homocysteine, which is known to be high in people with heart disease.
In addition, beans contain healthy amounts of minerals like iron, calcium, magnesium, manganese, and potassium, which are very essential for body metabolism.
