Cashews are often referred to as a nut, but botanically they are classed as a seed, as they come from the cashew fruit (which is also known as a drupe). Drupes are fruits that are fleshy on the outside, but contain a shell with a seed on the inside.

Nutritionally, cashew nuts are a good source of protein and unsaturated fat. A 30g serving contains about 160 calories, but because they are rich in protein and unsaturated fat, they provide a greater satiety level.
