A typical 1 cup cooked serving of rice noodles contains 3.2 grams of protein (1.79 g per 100 g), which makes it a moderate source of protein. That covers roughly 6% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 7% of the calories in rice noodles come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Among the 111 grains in the database, rice noodles ranks 77th by protein per serving, and 585th out of all 796 foods on the site. Set against dinner roll, another grain entry in the database, a serving carries about 0.5 g more protein (dinner roll has 2.7 g per 1 roll).
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 176 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Made from rice flour only, so noticeably lower in protein than wheat pasta.
