Understanding Peanuts Nutrition
Peanuts are a nutrient-dense nut or seed rich in healthy fats, fiber and minerals. At 575 kcal per 100 g serving, they provide 26.1g of protein, 16.4g of carbohydrate and 50g of fat. Peanuts are particularly rich in magnesium, delivering 171mg — 39% of the daily value — in a single serving. They have modest fiber and 4.6g sugar.
For athletes and anyone tracking macros, peanuts are calorie-dense and work well for adding calories without added volume, thanks to their fat content. Because they're calorie-dense, they're easiest to track in small, pre-measured portions rather than free-pouring.
