Calories in a Lime: Full Nutrition Breakdown

Limes are small, tart citrus fruits widely used for their juice and zest in cooking, beverages, and cocktails. Like lemons, they are extremely low in calories while providing a good dose of vitamin C and beneficial plant compounds. Limes also contain unique flavonoids with antioxidant and anti-inflammatory properties.

Calories by serving size:

Limes are about 88% water and contain citric acid, which gives them their characteristic sour taste. The citric acid content also helps enhance iron absorption from plant-based foods when limes are consumed alongside meals.

Frequently Asked Questions (FAQ)

How many calories are in lime juice?

The juice of one lime (about 44 ml) contains approximately 11 calories, with 4 grams of carbohydrates and only 1 gram of sugar. Lime juice is one of the lowest-calorie ways to add bold flavor to food, drinks, and marinades. A squeeze of lime over a dish adds virtually no calories.

Are limes as nutritious as lemons?

Limes and lemons are very similar nutritionally, but lemons contain slightly more vitamin C (53 mg vs. 29 mg per 100 g). Limes contain slightly more vitamin A. Both are excellent low-calorie sources of vitamin C and citric acid, and both provide similar flavonoids. The choice between them is largely a matter of flavor preference and recipe requirements.

Does lime juice help with iron absorption?

Yes. The vitamin C and citric acid in lime juice significantly enhance the absorption of non-heme iron (the type found in plant foods like beans, spinach, and fortified cereals). Squeezing lime juice over iron-rich foods or eating lime alongside them can increase iron absorption by 2–3 times, making it a simple strategy for people at risk of iron deficiency.

Is lime water good for you?

Lime water is an excellent zero- to low-calorie beverage. Adding the juice of half a lime to a glass of water adds about 5 calories while providing vitamin C, citric acid, and a pleasant flavor that encourages hydration. The citric acid may also help prevent kidney stones by increasing urinary citrate levels. It is a healthier alternative to soda, juice, or flavored drinks.

Can lime juice damage tooth enamel?

Yes, like all citrus juices, lime juice is acidic (pH around 2–2.5) and can erode tooth enamel with prolonged exposure. To minimize damage, drink lime water through a straw, avoid swishing acidic drinks around your mouth, rinse with plain water afterward, and wait at least 30 minutes before brushing your teeth. Occasional use in cooking and moderate lime water consumption pose minimal risk.
