This small citrus fruit with origins in Asia packs a large nutritional punch. According to the United States Department of Agriculture (USDA), one lime with a 2-inch diameter contains just 20 calories.
The same size lime also contains the following nutrients:
- 22 milligrams (mg) calcium
- 12 mg phosphorus
- 68 mg potassium
- 19.5 mg vitamin C, which is about 20–25 percent of the daily value recommended for adults
In addition to the nutritional value of limes, lime water has the following benefits:
1. Promotes consumption of water
The Centers for Disease Control and Prevention (CDC) suggest that people who do not drink enough water could add a squeeze of lime to enhance the flavor, which may encourage them to drink more water.
2. Helps improve diet
A recent study in Nutritional Epidemiology showed that people who drank more water instead of sugary drinks, such as soda or juice, improved their diet.
People who drank water instead of sweetened drinks reduced the amount of sugar and fat they consumed on a daily basis.
3. May aid digestion
Adding lime to water can help aid digestion. Limes contain compounds that help stimulate digestive secretions in the stomach. Also, the acid in the lime juice helps the saliva break down food.
4. Reduces cancer chances
Several studies show a link between citrus fruit and a reduced risk of some types of cancer. A 2015 study in Medicine (Baltimore) showed a possible link between increased citrus fruit consumption and a diminished risk of esophageal cancer. However, more research is required.
5. Improves skin quality
Limes contain vitamin C and antioxidants, both of which are ingredients in many commercial skin products. When consumed with water, the natural ingredients in the lime juice can help improve the appearance of aging skin.
6. Promotes weight loss
Nutritionists often recommend drinking a glass of water with a meal to help prevent overeating.
Lime water has an additional benefit. The citric acid found in lime juice helps boost a person’s metabolism, helping them burn more calories and store less fat.
7. Improves immune system
The vitamin C combined with the antioxidants contained in limes provide support to the body’s immune system.
When drunk regularly, lime water might help prevent and shorten the lifespan of colds and cases of flu.
8. Reduces risk of heart disease
Limes contain high levels of magnesium and potassium.
Both of these elements help support the overall health of the heart. In particular, potassium can improve blood flow and reduce blood pressure.
9. Lowers blood sugar
According to some research, vitamin C can help lower morning and post-meal blood sugar changes. Though the study focused on people taking supplements of vitamin C, the conclusion indicated that vitamin C offers excellent potential for improving a person’s sugar levels.
10. Prevents the growth of micro-organisms
According to some research, the limonins found in limes can help prevent the accumulation of Streptococcus bacteria.
Streptococcus is a type of bacteria responsible for a variety of infections and health conditions, including respiratory and mouth infections.
Drinking lime water may help stop these harmful organisms from developing and prevent bacterial illnesses.
11. Has anti-inflammatory properties
Limes provide a good source of vitamin C. Among many other potential benefits, vitamin C acts as an anti-inflammatory agent in the body.
They concluded that the majority of studies indicated that the use of vitamin C showed favorable results in reducing inflammation.
12. Helps prevent kidney stones
Lime water is easy to make:
- Wash a fresh lime before cutting it.
- Fill a glass with water and squeeze the juice from a piece of the lime into the water.
- To make lime water ahead of time, fill a pitcher with water and squeeze in the juice of a whole lime.
- Add lime slices to the pitcher for added flavor.
- Drink the water within 1 day for best flavor.
For people who have trouble drinking the recommended amount of water each day, lime water may be a good alternative.
In addition to extra flavor, lime water also offers additional nutrients that may have a variety of health benefits.
Lime water is easy to prepare, and almost everyone can add it to their diet.
