Peanuts originated in South America and have been around for thousands of years. Peanuts are not a nut – they are a legume, related to beans, lentils, and peas.
They have a veined brown shell, or pod, that contains two or three peanut kernels. They have a hardy, buttery nut taste. The peanuts inside have a papery sheath that can be eaten or removed. The peanuts you purchase at your farmers' market are raw, so you will need to cook them either by boiling or roasting.
Peanuts are an excellent source of protein and dietary fiber. They also contain good amounts of copper and biotin, folate, vitamin B3, manganese, and heart-healthy monounsaturated fat.
