161 calories per ounce


Calories are a measure of the amount of energy in a particular item of food or beverage. And exerting energy in direct balance with caloric intake is key to maintaining a healthy weight. Peanuts and peanut butter are nutrient-dense foods which are an important factor in weight management. In just one serving (160 calories of peanuts, or about 190 calories for peanut butter), they provide hard-to-get nutrients such as dietary fiber, potassium, folate, vitamin E, thiamin, and magnesium. Furthermore, there are numerous studies showing that peanuts help manage weight because of their high satiety value, and because consumers don’t tire of their flavor, texture or versatility.
7.3g protein per ounce


A one-ounce serving of peanuts—about a handful—is considered a good source of protein based on the United States Department of Agriculture Nutrient Database. Although the nutrition data of peanuts and peanut butter can differ slightly, a serving of each provides 7 grams of high quality, plant-based protein to your diet. Since the protein in peanuts is plant-based, it carries with it additional components promoting positive health benefits like fiber and unique bioactives, unlike animal protein.
4.6g carbohydrates per ounce


Carbohydrates (or ‘carbs’) are an important part of a healthy diet; they supply the body with glucose which ultimately supports physical activity and bodily functions. Peanuts can be an ideal factor in this equation, as they are quick to enter the bloodstream and result in energy. But how many carbs are in a serving of peanuts? Well, as peanuts are high in protein, fat and fiber, they are low in carbohydrates – which means they have a low glycemic index. As such, foods containing a low amount of carbohydrates, such as peanuts, are also critical to those trying to lose weight, lower blood sugars and treat certain health conditions.
14g fat per ounce

Healthy Fat

The 2020-2025 Dietary Guidelines for Americans suggest cooking and purchasing products made with oils higher in polyunsaturated and monounsaturated fat rather than butter, shortening, or coconut or palm oils.

Scientific studies show that when healthy fats replace bad fats in our diets, it lowers inflammation and risk of cardiovascular disease.
