Around 27% of the calories in sugar snap peas 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 105 vegetables in the database, sugar snap peas ranks 57th by protein per serving, and 666th out of all 796 foods on the site. Set against alfalfa sprouts, another vegetable entry in the database, a serving carries about 0.5 g more protein (alfalfa sprouts has 1.3 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 63 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
