Green beans are low in calories, high in fiber, and full of nutrients. They provide antioxidant vitamins A and C, as well as vitamin K and the B vitamins thiamine, niacin, riboflavin, and folate. Minerals found in green beans include manganese, potassium, iron, calcium, copper, and phosphorus. This wealth of nutrients gives green beans great potential in preventing cancers, heart disease, and other illnesses in which inflammation plays a role.
Green beans are, however, another food that has measurable amounts of oxalates, so over-consumption can cause problems for those with kidney disease, gout, vulvar pain, rheumatoid arthritis, or other conditions that may require a lowoxalate diet.Nutritional Facts
