What Are Peanuts, Actually? The Answer Might Surprise You: They’re Beans!

Peanuts are a pantry staple, whether they’re roasted, turned into butter, or added to recipes. Despite their name and nut-like qualities, peanuts belong to the legume family, making them more closely related to beans and lentils than almonds or walnuts. A good understanding of what peanuts truly are can help us appreciate their unique qualities and how they differ from other "nuts."

Why Are Peanuts Considered Beans?

Peanuts grow underground, which is the first clue that they’re not nuts. Unlike tree nuts, such as almonds and hazelnuts, peanuts are legumes, meaning they are seeds that develop in pods.

• Botanical classification: Peanuts belong to the Fabaceae family, the same family as beans, peas, and lentils.
• Growth process: After flowering, peanut plants form pods that burrow into the soil, where the peanuts mature. This underground growth is a key characteristic of legumes.
• Nutritional similarity: Like beans, peanuts are rich in plant-based protein, fibre, and essential nutrients, which sets them apart from tree nuts that are higher in fats.

The History and Uses of Peanuts

Peanuts originated in South America and have been cultivated for thousands of years, gaining popularity for their incredible adaptability. They’ve become a staple in cuisines worldwide, featuring in everything from peanut butter and oil to boiled peanuts and desserts.

Today, peanuts are grown in warm climates across Asia, Africa, and the Americas, solidifying their status as a truly global crop. They play a starring role in dishes like satay sauce, peanut brittle, and hearty soups, showcasing their ability to improve both savory and sweet recipes. Peanuts are a nutritional powerhouse, packed with protein, healthy fats, and essential nutrients like magnesium and vitamin E, making them a valuable addition to any diet.

Are Peanuts Safe for Everyone?

While peanuts are nutrient-dense, they are also one of the most common allergens. For individuals with peanut allergies, even small traces can trigger severe reactions. However, for most people, peanuts are a healthy addition to the diet when consumed in moderation.

Overall, although peanuts may look and taste like nuts, they're firmly rooted in the legume family alongside beans and lentils. Whether enjoyed as a snack or applied in recipes, peanuts continue to be a favorite worldwide.
