It’s kind of a trick question because peanuts are a legume but considered a nut from a nutritional and culinary standpoint. With 9.5 grams of protein per 1/4 cup (37 grams), peanuts beat out all other nuts on the list in terms of protein content. They likewise provide a healthy dose of biotin and other nutrients.
Like most legumes, they provide a lot of plant-based protein. In fact, peanuts have the highest protein content out of all commonly consumed nuts.
Peanuts are also one of the best food sources of biotin, a vitamin that helps convert food into usable energy in the body. For a balanced snack that provides protein, fats, and carbs, combine peanut butter and bananas on their own, or assemble them on top of toast.
