Protein Sources: A common concern about vegetarian and vegan diets is that they might lack sufficient protein.
However, many experts agree that a well-planned vegetarian or vegan diet can provide you with all the nutrients you need (Trusted Source).
That said, certain plant foods contain significantly more protein than others.
And higher-protein diets can promote muscle strength, satiety and weight loss (Trusted Source).
Here are 17 plant foods that contain a high amount of protein per serving.
