One 1 cup cooked, 17.3 g protein.
Every 100 kcal of adzuki beans brings 5.9 g of protein. On that measure it ranks 33rd of the 54 legumes in this database and 417th of all 796 foods on the site. Measured by weight instead, its 7.52 g per 100 g ranks 40th in its group.
Around 24% of the calories in adzuki 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 0.1 g of fat per 100 g of adzuki beans, too little for a protein-to-fat ratio to mean much.
Set against lentils, another legume entry in the database, a serving carries about 0.6 g less protein (lentils has 17.9 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 230 g, and it covers about 35% of the 50 g FDA Daily Value for protein.
Serving sizes
| Portion | Weight | Protein | Calories |
|---|---|---|---|
| 100 g | 100 g | 7.52 g | 128 kcal |
| 1 cup cooked (serving used here) | 230 g | 17.3 g | 294 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 | 0.632 g | 1.45 g | 84 |
| lysine | 0.567 g | 1.3 g | 75 |
| valine | 0.387 g | 0.89 g | 51 |
| isoleucine | 0.3 g | 0.69 g | 40 |
| threonine | 0.255 g | 0.59 g | 34 |
| phenylalanine | 0.398 g | 0.92 g | 53 |
| methionine | 0.079 g | 0.18 g | 11 |
| histidine | 0.198 g | 0.46 g | 26 |
| tryptophan | 0.072 g | 0.17 g | 10 |
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
7.52 g. The 1 cup cooked serving used on this page weighs 230 g and so carries 17.3 g.
5.9 g. That figure divides its 7.52 g of protein per 100 g by its 128 kcal per 100 g, so it does not depend on serving size.
No. On its own, the protein in adzuki beans is short of at least one essential amino acid; other protein sources across the day fill the gap.
About 35%. One 1 cup cooked serving has 17.3 g, and the FDA Daily Value for protein is 50 g.
