Every 100 kcal of somen noodles brings 3.1 g of protein. On that measure it ranks 67th of the 111 grains in this database and 624th of all 796 foods on the site. Measured by weight instead, its 4 g per 100 g ranks 87th in its group.
Around 12% of the calories in somen noodles 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.
USDA lists 0.18 g of fat per 100 g of somen noodles, too little for a protein-to-fat ratio to mean much.
Set against wild rice, another grain entry in the database, a serving carries about 0.5 g more protein (wild rice has 6.5 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 quoted here is measured by volume at 176 g, and it covers about 14% of the 50 g FDA Daily Value for protein.

Per-100 g values are the amino acid analysis on the USDA record. The serving and per-gram-of-protein columns are arithmetic on those values; they are not a protein quality score.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
4 g. The 1 cup cooked serving used on this page weighs 176 g and so carries 7 g.
How much protein do you get per 100 calories of somen noodles?
3.1 g. That figure divides its 4 g of protein per 100 g by its 131 kcal per 100 g, so it does not depend on serving size.
Is the protein in somen noodles complete?
No. On its own, the protein in somen noodles is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of somen noodles?
About 14%. One 1 cup cooked serving has 7 g, and the FDA Daily Value for protein is 50 g.
