Green Beans
Green beans, while quite low in calories (just 43.75 calories in a whole cup), are loaded with nutrients — an excellent source of vitamin K, vitamin C, manganese, vitamin A, dietary fiber, potassium, folate, and iron. And, green beans are a good source of magnesium, thiamin, riboflavin, copper, calcium, phosphorus, protein, omega-3 fatty acids and niacin.
