Chestnuts also contain comprehensive minerals, such as potassium, magnesium, iron, zinc and manganese. Although the content is not as high as hazelnut and melon seeds, it is still much higher than that of apples, pears and other ordinary fruits, especially the potassium content is outstanding, which is four times higher than that of apples which are said to be rich in potassium.
