peanut butter

Peanut butter is a protein-rich spread made from ground, dry-roasted peanuts. While often categorized as a dietary staple or supplement for its nutrient density, it is technically a whole food. It provides a powerhouse combination of healthy monounsaturated fats, plant-based protein, and essential micronutrients like magnesium and niacin. Unlike synthetic supplements, peanut butter offers these nutrients in a complex food matrix that supports sustained energy, heart health, and muscle recovery. It is a calorie-dense food, making it an excellent tool for those looking to increase their caloric intake naturally.

Deep Dive

Peanut butter is more than just a tasty treat; it is a functional food. The primary fat it contains is oleic acid, the same healthy fat found in olive oil, which is linked to reduced inflammation. Regarding protein, it offers about 8 grams per serving, making it a vital tool for vegetarians or those on plant-forward diets. Furthermore, it contains resveratrol, an antioxidant also found in grapes, which supports cellular health. While it is energy-dense, the nutrients it provides help curb cravings and support metabolic health.
