11 Nuts That Pack the Most Protein

|Updated Dec 13, 2022

Nuts are some of the healthiest foods on the planet — especially if you're looking for a protein-filled snack in a nutrient-dense package. While they're high in fat (nuts are about 80 percent fat), it's unsaturated fat, which is considered heart-healthy because it's thought to lower your overall cholesterol.

Are Nuts Good for You?

Nuts also contain fiber, Omega-3 fatty acids (the anti-inflammatory kind also found in fish), and vitamin E, which is good for your heart and your skin. Nuts contain powerful elements like L-arginine which some take to improve circulation and erectile dysfunction, and plant sterols, which are added to foods like orange juice to make them heart-healthier. Basically, nuts are superfoods.

The only downside to nuts is that they can be little calorie bombs. The American Heart Association recommends eating only four servings of unsalted nuts a week. It's also recommended to eat raw or dry-roasted nuts, not the oily, greasy or sugary ones. And note that a serving is a small handful (1.5 ounces) of whole nuts or 2 tablespoons of nut butter.
For the best choices when it comes to maximizing the protein content in your nut choice, we went to the USDA to find out which nuts pack the biggest protein punch.

11 Nuts With the Most Protein

Peanuts have 7.31 grams per ounce or 37.7 grams of protein per cup.

Crazy stunt: Scientists have made diamonds out of peanuts by putting them under enormous pressure. 1 ounce equals Protein - 7.31 g Calories - 161 Carbs - 4.57 g Fiber - 2.41 g Calcium - 26.1 mg


Almonds have 6 grams per ounce or 30.2 grams of protein per cup.
