Walnut

The history of walnuts dates back to 10,000 BCE. Walnuts are rich in nutrients, and they are the oldest tree food in the world. They are incredibly health-beneficial sources and are high in nutrients, antioxidants, and minerals. Walnuts are used to make various foods, pastries, cookies, cakes, etc. China and United States are the largest producers of walnut worldwide, and the Middle East is also known to produce this highly consumed trail mix ingredient. Iran accounts for the highest consumption of walnut around the world, after China and United States. The edible, wrinkled, brown-colored nuts that are covered in a brown seed coat are known as walnut kernels. They come from walnut trees in the genus Juglan, which are members of the Juglandaceae family. Two bumpy lobes on the kernels resemble abstract butterflies.
