A typical 1 cup cooked serving of cabbage contains 1.9 grams of protein (1.27 g per 100 g), which makes it only a minor source of protein. That covers roughly 4% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 22% of the calories in cabbage come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 105 vegetables in the database, cabbage ranks 55th by protein per serving, and 660th out of all 796 foods on the site. Set against green beans, another vegetable entry in the database, a serving carries about 0.5 g less protein (green beans has 2.4 g per 1 cup cooked).
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 150 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
