Protein content
A 1 fruit serving of guava contains 1.4 g of protein - only a minor source of protein, about 3% of the 50 g Daily Value.
Share of this food's calories that come from protein - it is more of an energy food than a protein food.

A typical 1 fruit serving of guava contains 1.4 grams of protein (2.55 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.
Around 15% of the calories in guava come from protein, so it is more of an energy food than a protein food. 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 71 fruits in the database, guava 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 55 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
