Walnuts come from trees in the Juglans genus, specifically Persian walnuts which are also referred to as Juglans regia. The seeds which walnuts form from are packed with all kinds of nutrients that are necessary for the body to get enough of, which is partially why they are considered to be so healthy and favored by vegetarians.

These seeds are also high in fatty acids that are great for the body along with protein and small amounts of potassium. It can be easy for walnuts to become infested with mold or have problems with final infestations if they are not stored properly.
