Better Health with Budget-friendly Peanuts

ALBANY, Ga., Jan. 24, 2023 - With food costs on the rise, consumers are looking for meals and recipes that stretch their dollar. According to The Peanut Institute, peanuts and peanut butter are some of the most affordable, nutrient-dense sources of protein available.

A one-ounce serving of peanuts, which is about a handful, costs about 15 cents, delivers seven grams of plant-based protein plus 19 vitamins and minerals, heart-healthy fats and fiber.

"Research has shown that substituting plant protein for animal-based protein can help add years to your life1," says Dr. Samara Sterling, a nutrition scientist and research director for The Peanut Institute. "Making smart food choices each and every day adds up to a healthy lifestyle that's beneficial for you and your family."

Since they're packed with vitamins and minerals, peanuts and peanut butter deliver both short-term and long-term benefits that can have a positive impact on every stage of life.

Healthy development in children of the brain, bones, muscles and immune system. Peanuts also contain arginine, which is an amino acid associated with higher growth velocity.2
Healthy weight management in adults by delivering greater hunger satisfaction. A recent study found that participants who snacked on peanuts and peanut butter tended to consume fewer calories than those who ate other nuts, including almonds.3
Protection against certain cancers with antioxidants and phytosterols that have been shown to be beneficial against brain, skin, stomach, colon, breast, pancreatic and prostate cancers.
Keeping minds sharp during aging thanks to compounds that increase brain blood flow, protect against Alzheimer's disease and even fight anxiety and depression. Niacin in particular is associated with a reduced rate of cognitive decline.4
Good for the body and better for the planet

While the health benefits for peanuts stack up, they're also earth friendly.

Since peanuts are technically legumes, they're easier to grow and harvest than pricier tree nuts.

Peanuts require less water than tree nuts.5 Compared to almonds, peanuts need less than half the water to grow. (2,782 vs. 8,000 cubic meters per in-shell ton)
Peanuts enrich the soil with nitrogen to make the land more fertile. They produce 90% of their own nitrogen, which means they help create a more sustainable world.
Peanuts produce fewer greenhouse gasses. Peanut butter produces just 2.9 units of CO2 emissions, which is less than half that of eggs (4.8 units) and less than a quarter of cheese (13.5 units).
Those stats, combined with the long shelf life of peanuts and peanut butter, equal a convenient, sustainable, cost-efficient food that's great to keep on-hand.
