A typical 1 cup cooked serving of swiss chard contains 3.3 grams of protein (1.88 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 swiss chard, 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.
Among the 105 vegetables in the database, swiss chard ranks 30th by protein per serving, and 584th out of all 796 foods on the site. Set against oyster mushrooms, another vegetable entry in the database, a serving carries about 0.5 g more protein (oyster mushrooms has 2.8 g per 1 cup sliced).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by volume at 175 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
