Some interesting facts about peanuts (Arachis hypogaea):
Technically not a nut:
Despite the name, peanuts are classified as legumes, along with peas, beans, and lentils. This is because they grow in pods underground and fix nitrogen in the soil through bacteria in their roots.
Underground trick:
Peanuts are unique legumes because their flowers develop above ground, but after fertilization, the flower stalk (peg) elongates and pushes the developing pod underground where the peanut matures. This is called geocarpy.
South American origins:
Peanuts originated in South America thousands of years ago and were cultivated by indigenous people there. Spanish explorers introduced them to Europe and Asia in the 16th century.
Powerhouse of nutrients:
Peanuts are a nutritional powerhouse, packed with protein, healthy fats, fiber, vitamins, and minerals. They are a valuable source of essential nutrients, especially for people in developing countries.
Double duty crop:
Peanuts are considered both a grain legume due to their high protein content and an oilseed crop because of their oil content. Peanut oil is a popular cooking oil around the world.
Global favorite:
China is the leading producer of peanuts worldwide, followed by India and the United States. Peanuts are a versatile food enjoyed in various forms, from peanut butter and roasted peanuts to snacks and peanut oil.
