Are Peanuts Nuts?

When it comes to categorizing food, things can get quite confusing. Take the example of tomatoes and avocados, which grow like fruit but taste like vegetables. Similarly, a watermelon is actually a berry, and so is an eggplant. But what about peanuts? Are they really nuts?

Contrary to popular belief, peanuts are not nuts; they are legumes. Like soybeans and lentils, peanuts are edible seeds that grow in pods. Despite this, most people tend to think of them as nuts, along with tree nuts such as walnuts, almonds, and hazelnuts. Unlike other legumes that grow on vines or shrubs, peanuts grow underground.

The Nutritional Similarities

In terms of nutrition, peanuts and tree nuts share several similarities. They are all rich in healthy unsaturated fats and fiber, as well as various vitamins and minerals. Numerous studies have indicated that individuals who consume peanuts or tree nuts regularly have lower rates of heart disease compared to those who rarely include them in their diet. Additionally, peanuts are a more affordable option than tree nuts, making them an accessible addition to daily meals.

Healthy Ways to Enjoy Peanuts

For those who enjoy peanut butter, opting for a brand that contains 100% peanuts without added sugar or salt is recommended. It can be spread on whole-grain bread and topped with thinly sliced apple or banana instead of jelly or jam. Peanut butter can also be used to create peanut sauce for drizzling over steamed broccoli or other vegetables. Chopped, roasted peanuts can be added to a stir-fry, or a small handful of unsalted peanuts can be enjoyed as a snack.

Understanding the Botanical Classification

From a botanical perspective, the confusion arises due to the difference in how consumers and botanists categorize nuts. While consumers base their classification on the appearance and texture of the food found on grocery shelves, botanists consider the entire plant. A true botanical nut is a dry fruit with a single seed encased in a hard, nonsplitting ovary wall. Examples of true nuts include walnuts, chestnuts, hazelnuts, and acorns. On the other hand, peanuts, almonds, cashews, and pecans do not meet the botanical criteria for nuts.

Botanical Misnomers

Almonds, cashews, and pecans are actually seeds inside a drupe, which is a type of stone fruit. Unlike the hard outer shell of a true nut, a drupe has a fleshy outer layer surrounding a pit that contains the seed. Brazil nuts, on the other hand, are disqualified from being true nuts because they grow inside a pod, with 10 to 25 nuts in a single pod. This places them in a category distinct from true nuts, legumes, or drupes.

FAQs

Are peanuts safe for individuals with nut allergies?

Despite the name, peanuts are not true nuts, and individuals with nut allergies may not necessarily be allergic to peanuts. However, cross-reactivity between peanuts and tree nuts is possible, so it is essential for individuals with nut allergies to consult an allergist for personalized advice.

Can peanuts be included in a weight loss diet?

When consumed in moderation, peanuts can be a part of a weight loss diet due to their satiating effect and nutrient density. However, portion control is crucial, as peanuts are calorie-dense.

Do peanuts provide any health benefits?

Yes, peanuts offer various health benefits, including being a good source of healthy fats, protein, fiber, and essential nutrients such as vitamin E, magnesium, and potassium. Regular consumption of peanuts has been associated with a reduced risk of heart disease and improved overall health.
