A typical 1 cup cooked serving of beet greens contains 3.7 grams of protein (2.57 g per 100 g), which makes it a moderate source of protein. That covers roughly 7% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Protein accounts for roughly 38% of the calories in beet greens, making it very protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
