In many parts of Africa, peanuts are usually known as groundnuts because the nut pods
grow underground. Peanuts play an important nutritional role in many parts of Africa, since they have good fats and contain 7 grams of protein which helps combat child malnutrition. They grow well in semi-arid regions and are a staple food as well as a revenue source for farmers. Although native to South America, the Portuguese introduced peanuts into their African enclaves, where they quickly spread throughout tropical Africa.
