Both lemon juice and lime juice add a tart, zesty flavor to smoothies, marinades or other recipes, but lemons contain a bit more vitamin C than limes. Even though they differ in the color of their rind and the way they taste, there are only small differences in nutritional content between the two citrus fruits. Their nutritional benefits provide plenty of reasons to add more lemons and limes to your grocery list.
Nutrient Content of Limes and Lemons
One-fourth cup of lemon or lime juice contains 13 to 15 calories and 4 to 5 grams of carbohydrate, making them very low-calorie fruit juices. The whole fruits are similar in fiber content, offering approximately 2 grams of fiber, which is 8 percent of your Daily Value, in one whole peeled and sliced lime or lemon.
On the other hand, whereas 1/4 cup of lime juice contains 20 to 24 percent of your daily vitamin C needs, lemon juice has a little more of this detoxifying and immunity-enhancing vitamin, with 26 to 31 percent.
Compared to limes, lemons are also slightly higher in flavonoids, a phytochemical that helps prevent cancer and diabetes, stimulates your digestive system, has anti-congestive benefits and contributes to blood and skin health. Both citrus fruits also contain bitter compounds known as limonoids, which contribute antioxidant, anti-cancer, cholesterol-lowering and antiviral properties.
