(NewsUSA) - With food costs on the rise, many people 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 approximately 35 nuts, 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 life,” said 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.

• For children, healthy development of the brain, bones, muscles and immune system. Peanuts also contain arginine, which is an amino acid associated with higher growth velocity.

• In adults, healthy weight management 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. 

• In older adults, 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.

• For everyone, 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.

Peanuts and peanut butter are great any time of day.
