26 of the Best High Protein Foods

26. Broccoli, Spinach, and Kale

Leafy greens are full of key vitamins, minerals, and fiber that contribute to a healthy diet and body. Though they are not famous for their protein levels, they are not slacking in that area either. Each 100-gram serving of kale comes with nearly three grams of protein and only about 40 calories.

Broccoli and spinach both offer similar protein levels and calorie counts—though spinach has the fewest calories. It is best to eat these foods raw, as cooking them can impact their nutrient profiles.
