Every 100 kcal of french beans brings 5.5 g of protein. On that measure it ranks 36th of the 54 legumes in this database and 440th of all 796 foods on the site. Measured by weight instead, its 7.05 g per 100 g ranks 41st in its group.
Around 22% of the calories in french beans 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.
Weight for weight, french beans has 9.3 g of protein for each gram of fat (7.05 g against 0.76 g per 100 g).
Set against black-eyed peas, another legume entry in the database, a serving carries about 0.7 g less protein (black-eyed peas has 13.2 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 177 g, and it covers about 25% of the 50 g FDA Daily Value for protein.

How much protein do you get per 100 calories of french beans?
5.5 g. That figure divides its 7.05 g of protein per 100 g by its 129 kcal per 100 g, so it does not depend on serving size.
Is the protein in french beans complete?
No. On its own, the protein in french beans 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 french beans?
About 25%. One 1 cup cooked serving has 12.5 g, and the FDA Daily Value for protein is 50 g.
