A typical 1 cup cooked serving of wild rice contains 6.5 grams of protein (3.99 g per 100 g), which makes it a moderate source of protein. That covers roughly 13% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 16% of the calories in wild rice come from protein, so it is more of an energy food than a protein food. 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 111 grains in the database, wild rice ranks 23rd by protein per serving, and 408th out of all 796 foods on the site. Set against couscous, another grain entry in the database, a serving carries about 0.5 g more protein (couscous has 6 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 164 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
A grass seed rather than true rice, with more protein than white rice.
