Did you know the most popular nut in the world isn’t actually a nut?
In fact, the peanut (Arachis hypogaea) is more closely related to peas than nuts.
As well as being enjoyed as a snack, peanuts are packed with proteins, healthy fats, vitamins and minerals.
When a peanut flower is pollinated, the stalk elongates to bury itself in the soil where the seed develops, pre-planted, in a process known as 'geocarpy'.
Peanut plants grow as a bush up to 50cm tall and wide. The leaves are made of four smaller leaflets, which are oval shaped and between 1 to 7cm long. The flowers are small, loosely resemble butterflies, and can be red to orange to yellow. The seeds grow underground, surrounded by an outer pod.
Beauty and cosmetics
Peanut oil is used in the production of some soaps and cosmetics.
Food and drink
Peanuts are commonly eaten as a snack, either raw, roasted or boiled.
Peanut butter is made from dry roasted peanuts sometimes mixed with fats and sugars.
Peanuts are used in savoury dishes, often to make a sauce served with meat.
Peanuts are also processed to produce peanut oil, which is commonly used for cooking, and peanut milk.
Peanuts are an excellent source of protein, monounsaturated fats and multiple vitamins and minerals.
Materials and fuels
The leftover material from creating peanut oil can be used as animal feed.
