What is fun to eat, oh-so-tasty, but sometimes gets a bad rap and is actually healthy? Environmental Health looks at peanuts as a nutritional powerhouse – and not just for kids.

The peanut is not just an American tradition at baseball games, pubs, and as part of the iconic peanut butter and jelly sandwich, it’s also a global culinary superstar and a nutrient powerhouse.

The folklore to the future

Native to South America, this dietary staple dates back thousands of years. Aztecs also used peanuts medicinally to cure fever and soothe sore gums. Today, every part of the peanut is put to good use.

The facts of this not-a-nut

Nut-like, but not a nut, the peanut (Arachis hypogaea) is a legume in the same family as peas, lentils, and beans. Each brown veined pod, or shell, houses two or three “nuts,” or kernels, encased in a reddish papery skin. A one-ounce serving, about a handful, packs a filling 13% DV (Daily Value, based on 2,000 calories/day) of protein, 29% DV of bone-building manganese, a healthy dose of monounsaturated fatty acids, and antioxidant plant compounds.

The findings on peanuts as a nutritional powerhouse

Tree nuts and peanuts, which are protein- and energy-rich and contain several health-enhancing plant compounds, including resveratrol, have been associated with improving several risk factors related to age-related diseases, such as heart disease, cancers, and brain disorders, due to antioxidant and anti-inflammatory effects (Antioxidants, 2019).

Peanuts have also shown potential in help manage Type 2 diabetes. Patients with Type 2 diabetes who ate a low-carb diet that replaced part of a starchy carbohydrate food item with peanuts lowered their fasting blood glucose and blood sugar after a meal (Nutrients, 2018).

The finer points of everyday use

Peanuts come in options: peanut butter, peanut oil, peanut flour, and flakes, raw or roasted, shelled or unshelled, plain, or a variety of flavors. Store whole in-shell peanuts in a cool, dry place or refrigerated for longer freshness. Shelled and raw peanuts should be refrigerated or frozen, where they’ll keep up to six months.

Snacking on peanuts out of the shell is hard to beat, but try tossing roughly chopped peanuts into a stir-fry, over roasted vegetables, onto salads, or layered in a yogurt parfait. Blend them into a smooth butter that promises to make veggies, whole grain crackers, sauces, and dressings even tastier.
