Protein content
12.9 g of protein in 1 cup cooked (170 g) of fava beans, or 6.9 g for every 100 kcal it supplies.

One 1 cup cooked, 12.9 g protein.
Every 100 kcal of fava beans brings 6.9 g of protein. On that measure it ranks 11th of the 54 legumes in this database and 350th of all 796 foods on the site. Measured by weight instead, its 7.6 g per 100 g ranks 38th in its group.
Around 28% of the calories in fava 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.
USDA lists 0.4 g of fat per 100 g of fava beans, too little for a protein-to-fat ratio to mean much.
Set against black gram (urad dal), another legume entry in the database, a serving carries about 0.7 g less protein (black gram (urad dal) has 13.6 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 quoted here is measured by volume at 170 g, and it covers about 26% of the 50 g FDA Daily Value for protein.
Serving sizes
| Portion | Weight | Protein | Calories |
|---|---|---|---|
| 100 g | 100 g | 7.6 g | 110 kcal |
| 1 cup cooked (serving used here) | 170 g | 12.9 g | 187 kcal |
The USDA record lists no other household measure for this food; protein and calories scale from the per-100 g figures.
Amino acids
| Amino acid | Per 100 g | Per serving | mg per g protein |
|---|---|---|---|
| leucine | 0.572 g | 0.97 g | 75 |
| lysine | 0.486 g | 0.83 g | 64 |
| valine | 0.338 g | 0.57 g | 44 |
| isoleucine | 0.306 g | 0.52 g | 40 |
| threonine | 0.27 g | 0.46 g | 36 |
| phenylalanine | 0.321 g | 0.55 g | 42 |
| methionine | 0.062 g | 0.11 g | 8 |
| histidine | 0.193 g | 0.33 g | 25 |
| tryptophan | 0.072 g | 0.12 g | 9 |
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.

Quick answers
7.6 g. The 1 cup cooked serving used on this page weighs 170 g and so carries 12.9 g.
6.9 g. That figure divides its 7.6 g of protein per 100 g by its 110 kcal per 100 g, so it does not depend on serving size.
No. On its own, the protein in fava beans is short of at least one essential amino acid; other protein sources across the day fill the gap.
About 26%. One 1 cup cooked serving has 12.9 g, and the FDA Daily Value for protein is 50 g.
