Is a cashew nut or fruit?

The cashew (Anacardium occidentale) is a tree in the Anacardiaceae family. The fruit of the cashew is an edible seed, commonly referred to as a "cashew nut". The seed is surrounded by a hard, kidney-shaped shell. The shell contains a caustic, oily liquid called cardol. This must be removed before the nut can be consumed.

The cashew tree is native to northeastern Brazil. However, it is now cultivated in many tropical regions of the world. Cashews are a popular ingredient in many cuisines, and they are often used in snack mixes, desserts, and curries.

The cashew seed is a good source of protein, fiber, and vitamins and minerals. It is also a good source of antioxidants, which can help to protect the body from damage.
