About lime nutrition
Limes are small, sharp green citrus fruits. Most recipes use only the juice and zest, but USDA also measures the whole fruit, which is what these figures describe.
- Vitamin C: 19 mg in 1 lime (2 inch diameter), about 22 percent of the Daily Value.
How preparation changes the numbers
- Whole limes are rarely eaten in quantity, so the practical numbers are the juice and zest you add. A squeeze changes a recipe by only a few calories.
- Vitamin C is sensitive to heat (NIH Office of Dietary Supplements), so add lime late in cooking or at the table.
