Understanding how much protein asparagus contains is essential for those monitoring their dietary intake, especially in plant-based or vegetarian diets.
This article will explore how much protein is in asparagus, what contributes to its nutritional profile, and why incorporating asparagus into your meals may be beneficial. We will break it down by serving sizes, discuss its other nutritional benefits, and provide cooking methods to enjoy this delicious vegetable.
How Much Protein in Asparagus?
Asparagus contains approximately 2 to 3 grams of protein per 100 grams (about 3.5 ounces) when cooked. Raw asparagus has slightly less protein, at about 2.2 grams per 100 grams.
