Yes. On their nutrient profile, limes are a healthy choice: grade A on the open 2023 Nutri-Score algorithm, the top grade.
For
- Low in calories: 30 kcal per 100 g, so a serving (one, 70 g) is 21 kcal.
- Counts toward your fruit and vegetables: a 70 g serving is 18% of the 400 g a day the WHO advises.
A typical serving (one, 70 g) has 21 kcal, 0.5 g protein, 0.1 g fat and 7.4 g carbs. Other weights in the table.
How we judge this, and the sources
The answer comes from the food's composition, not from opinion: its Nutri-Score grade on the open 2023 algorithm, a traffic light for sugar, salt, saturated fat and fiber per 100 g, and the share of daily reference amounts in a typical serving (for salt, sugar, fiber and vegetables, those of the WHO). It rates the food's nutrient profile; it is not medical advice. Formulas, thresholds and every source are on the methodology page; last checked against the sources on September 30, 2026. The short food description was written by our language model (AI) — how we check the text.
A whole lime has about 20 calories and some vitamin C. Most limes end up squeezed: one gives about 2 tablespoons of juice.

*Where the numbers come from
Values per 100 g come from a single record of an open food composition table: USDA FoodData Central, FDC ID 168155, “Limes, raw” — the measured composition of this exact food, not an average across tables. Rounded. Carbohydrates are total carbohydrate, fiber included, as on a US Nutrition Facts label; salt is sodium × 2.5. Table licenses are on the data sources page.

*Where the vitamin numbers come from
Vitamins and minerals come from the USDA FoodData Central record “Limes, raw” (FDC ID 168155, SR Legacy; public domain), checked October 14, 2026; the record was matched to this food by calories, protein and fat. % DV is per serving, against the FDA Daily Values used on Nutrition Facts labels (2,000-calorie diet). The table lists nutrients that reach at least 2% DV per 100 g; the rest are absent or trace. Varieties, seasons and brands differ, and cooking in water leaches some vitamin C and B vitamins.

Limes: swaps and alternatives
No need to swap: limes already get grade A, the top of the scale, and nothing is in the red on the per-100 g traffic light: sugar 1.7 g (red is over 22.5 g), saturated fat 0 g (over 5 g) and salt 0 g (over 1.5 g). We only suggest a swap when it fixes a real problem. How we pick swaps.
