Protein content
0.5 g of protein in 1 fruit (67 g) of lime, or 2.3 g for every 100 kcal it supplies.
Share of this food's calories that come from protein - it is more of an energy food than a protein food.
| Protein per 100 kcal | 2.3 g |

One 1 fruit, 0.5 g protein.
Every 100 kcal of lime brings 2.3 g of protein. On that measure it ranks 11th of the 71 fruits in this database and 667th of all 796 foods on the site. Measured by weight instead, its 0.7 g per 100 g ranks 46th in its group.
Only about 9% of the calories in lime 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.
USDA lists 0.2 g of fat per 100 g of lime, too little for a protein-to-fat ratio to mean much.
Set against canned pineapple, another fruit entry in the database, a serving carries about 0.5 g less protein (canned pineapple has 1 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 quoted here is counted by piece at 67 g, and it covers about 1% of the 50 g FDA Daily Value for protein.
Serving sizes

Quick answers
0.7 g. The 1 fruit serving used on this page weighs 67 g and so carries 0.5 g.
2.3 g. That figure divides its 0.7 g of protein per 100 g by its 30 kcal per 100 g, so it does not depend on serving size.
No. On its own, the protein in lime is short of at least one essential amino acid; other protein sources across the day fill the gap.
About 1%. One 1 fruit serving has 0.5 g, and the FDA Daily Value for protein is 50 g.
