Potatoes
It is fascinating to know that a single potato is high in potassium, iron, copper, magnesium, and manganese. Along with this, potatoes are also loaded with vitamin C and most B vitamins. However, potatoes contain a little bit of almost every nutrient you need. There is a large population living on nothing but potatoes for a long time.
