A typical 1 medium serving of peach contains 1.4 grams of protein (0.91 g per 100 g), which makes it only a minor source of protein. That covers roughly 3% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 9% of the calories in peach come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Among the 71 fruits in the database, peach ranks 25th by protein per serving, and 697th out of all 796 foods on the site. Set against plantain, another fruit entry in the database, a serving carries about 0.5 g less protein (plantain has 1.9 g per 1 cup sliced raw).
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 counted by piece at 150 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
