The peanut (Arachis hypogaea), also known as the groundnut,goober (US),pindar (US) or monkey nut (UK), is a legume crop grown mainly for its edible seeds. The seeds are a nutritionally dense food, rich in protein and fat. Peanuts provide protein, vitamins, minerals, and antioxidants. They may have other health benefits, including promoting fullness and helping protect against heart disease. Peanuts are sold boiled or roasted and are commonly used to produce an edible oil with a high smoke point. In the United States the seeds are also ground into peanut butter and widely used in candy and bakery products. The peanut is used extensively as feed for livestock in some places. Other peanut products include peanut oil, flour, and protein. These goods are used in a variety of foods, such as desserts, cakes, confectionery, snacks, and sauces. It is classified as both a grain legume and, due to its high oil content, an oil crop. World annual production of shelled peanuts was 44 million tonnes in 2016, led by China with 38% of the world total.
