Believed to be native to Northeastern India where it has been grown since ancient times, the mung bean is a small, ellipsoid or cube-shaped seed that is slightly sweet and usually green, although it can also be yellow, olive, brown, purplish brown or black, mottled and/or ridged. The mung bean is a major edible legume seed in Asia, not to mention that it is an invaluable source of digestible protein in places where meat is lacking or where people are mostly vegetarian. Nutritionally, mung beans pack a nice nutritional punch – they are high in potassium, fiber, magnesium, and B vitamins, and they are also a good source of vitamin C. In fact, these seeds are a good source of antioxidants, which may reduce your risk of chronic diseases, such as heart disease, diabetes and certain cancers
