Among the 105 vegetables in the database, enoki mushrooms ranks 62nd by protein per serving, and 673rd out of all 796 foods on the site. Set against cooked carrots, another vegetable entry in the database, a serving carries about 0.5 g more protein (cooked carrots has 1.2 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 65 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
