A typical 1 cup cooked serving of lima beans contains 14.7 grams of protein (7.8 g per 100 g), which makes it a good source of protein. That covers roughly 29% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 27% of the calories in lima 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.
Among the 54 legumes in the database, lima beans ranks 22nd by protein per serving, and 255th out of all 796 foods on the site. Set against canned lentils, another legume entry in the database, a serving carries about 0.8 g less protein (canned lentils has 15.5 g per 1 cup).
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 188 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
