In addition to the above nutrients, limes also contain a small amount of vitamin A, vitamin E, vitamin K, copper, magnesium and phosphorus.
1. May Improve Heart Health
Studies show that eating lime fruit could reduce several heart disease risk factors and may help give your heart health a boost. One animal study in Iran, for example, showed that treating rabbits with lime juice and lime peels helped slow the progression of atherosclerosis, the buildup of plaque on the artery walls.
Limes are also loaded with vitamin C, an important nutrient that may be protective against heart disease. A study published in the Annals of Internal Medicine looked at the diets of 126,399 adults over an eight- to 14-year period and found that each serving of fruits and vegetables was associated with a 4 percent decreased risk of coronary heart disease. Researchers also noted that leafy green vegetables and vitamin C-rich fruits and veggies, like limes, had the greatest impact.
For best results when it comes to heart health, include limes as part of a balanced diet, and combine with a healthy lifestyle and regular physical activity.
2. Help Fight Against Cancer
One of the most impressive lime health benefits is its ability to fight against cancer cells in the body. This is because limes are jam-packed with antioxidants, which are compounds that fight against the harmful free radicals that can cause cell damage and chronic disease.
Limes contain a concentrated dose of many powerful phytochemicals, including flavonoids, flavones, triterpenoid and limonoids.
Several of the compounds found in limes have been shown to have potent cancer-fighting properties. In a test-tube study published in Plant Medica, one particular compound was isolated from lime extract and was found to block the growth of colon cancer cells by 67 percent after just 72 hours.
Other test-tube studies have shown that lime may be effective against other types of cancer as well, including breast cancer and pancreatic cancer. Plus, a 2023 study found that lime peel extract displays anti-cancer effects against human hepatocellular carcinoma cells.
3. Can Enhance Weight Loss
Many people enjoy a cold glass of water with a spritz of lime or lemon as a refreshing alternative to regular water, but did you know that weight loss could be one of the health benefits of lime juice with water?
If you regularly drink soda or juice, trading it in for lime water may amp up weight loss. For example, a can of cola has 136 calories, 35 grams of carbohydrates and 33 grams of sugar, plus next to no nutritional value. On the other hand, water is free of calories, carbs and sugar, and there are only 20 calories and seven grams of carbs in an entire lime.
Limes have also been shown to have some beneficial weight-reducing properties. An animal study in Iran, for instance, found that essential oil from limes was able to reduce both body weight and food consumption in mice.
Pair limes with a nutritious diet full of fruits and vegetables, limit your intake of ultra-processed foods, and squeeze in some exercise a few times per week to see the most results when you step on the scale.
4. Help Boost Immunity
Limes are an excellent source of vitamin C. Getting enough vitamin C in your diet is important for many aspects of health, but it’s especially crucial when it comes to immunity.
One review published in the Annals of Nutrition & Metabolism found that meeting your vitamin C needs could help reduce the duration and severity of respiratory tract infections and could also help prevent and improve the outcomes for malaria, diarrhea and pneumonia.
A few other natural immune system boosters include elderberry, ginger, ginseng and oregano.
5. Aid in Kidney Stone Prevention
Including a few servings of lemons or limes in your diet is one of the easiest ways to kick kidney stones to the curb. Like lemons, limes contain a good amount of citric acid, a type of acid that can help prevent kidney stones by increasing urinary citrate and urine volume.
Although there is limited research looking at the effects of limes on kidney stones specifically, there are many studies showing that increasing your citric acid intake could be beneficial in kidney stone prevention. One study, for example, showed that treating patients with lemonade therapy for almost four years decreased kidney stone formation from an average of one stone per year down to just 0.13 per year.
There is some research specifically on limes and kidney stones, however. For instance, lime powder has been found to help prevent stones “by increasing urinary concentrations of citrate and uromodulin, both of which are the potent inhibitors of calcium stone formation.”
You can also help prevent kidney stones by increasing your fluid intake, eating plenty of magnesium-rich foods and following a plant-based diet.
6. Increase Iron Absorption
Iron is a very important mineral. It is involved in the production of blood and is one of the main components of hemoglobin, which helps provide the body with the oxygen that it needs.
There are several groups that are at a higher risk for developing anemia. Vegans and vegetarians, for example, consume a form of iron that is not well-absorbed by the body, putting them at an increased risk for iron deficiency. Additionally, women are also at a higher risk due to blood loss during menstruation.
The vitamin C found in limes can actually help increase iron absorption to prevent iron deficiency anemia. In fact, a study published in the American Journal of Clinical Nutrition even found that consuming 100 milligrams of vitamin C with a meal increased iron absorption by 67 percent.
Limes vs. Lemons
Given their similarities in taste and nutrition, it’s easy to understand why so many people mix up these two citrus fruits. They’re both packed with vitamin C and antioxidants, supply similar benefits to health, and are both used to bring a bit of flavor and zing to recipes.
However, there are also plenty of differences that set apart the lime vs. lemon, including some pretty notable differences in appearance. Limes tend to be smaller than lemons and have a vibrant green color while lemons are bright yellow. Additionally, limes are often less sour and have a smoother taste, though they can be used interchangeably in many recipes.
As far as nutrition, though, there are some noteworthy differences between the two. Lemons are incredibly high in vitamin C. In fact, the amount of vitamin C in lemon vs. orange is almost equal.
Limes, on the other hand, are slightly lower in vitamin C. Gram for gram, there is about half the amount of vitamin C in limes vs. lemons.
The lemon nutrition profile is also a bit more substantial, with higher amounts of several micronutrients, like vitamin B6 and folate.
Limes are grown year-round, primarily in warm, tropical and subtropical regions around the world, such as India, Mexico and Egypt, though location can vary based on the type of lime.
They are also widely available at most grocery stores and can be found in the produce aisle, usually right next to the lemons and other citrus fruits. Look for a fruit that feels heavy for its size and has the characteristic bright lime color with minimal discoloration.
In cooking, limes are usually used to add a bit of zest and complement the flavors of foods and drinks. They are considered a staple ingredient in Thai, Mexican and Vietnamese cuisine and are even used for pickling in some parts of the world.
Limes are also commonly used to add flavor to cocktails and drinks.
There are a myriad of potential lime uses that extend beyond the kitchen as well. For example, lime extract can be found in some cleaning products, perfumes and aromatherapy oils.
If you’re ready to mix it up and try out some new uses for this nutritious citrus fruit, have no fear. There are plenty of lime and lime juice recipe options available for you to start experimenting with. Here are a few to get started:
- Cauliflower Rice with Cilantro and Lime
- Salty Lime Roasted Nuts
- Avocado Lime Hummus
- Frozen Berries with Coconut and Lime
There are many different types of limes, and most are actually hybrids of different types of citrus fruits, produced primarily from the citron, the pomelo and the mandarin orange. In the United States, the Persian lime is the most common variety found at grocery stores, but other types include the key lime, kaffir lime and wild lime.
The exact origins of the lime fruit are unknown, but it’s believed to have grown originally in Southeast Asia or Indonesia before being imported to Africa and the Mediterranean region around 1,000 years ago.
The true scope of its medicinal properties has only come to light in the past few centuries, however, when it was used to treat scurvy. Scurvy is a condition caused by vitamin C deficiency, which can result in symptoms like bleeding gums, bruising and fatigue. By the 18th century, scurvy had become a huge problem and a major cause of death for British sailors.
In 1747, scientist James Lind began conducting experiments on board a naval ship and discovered that drinking lemon and lime juice could help ward off scurvy thanks to the high concentration of vitamin C.
Today, researchers are continuing to learn more about the benefits of limes and the multitude of ways that they may impact health.
Risks and Side Effects
Limes are generally safe for most people and pose minimal risks to health. Still, there are some precautions and side effects that need to be considered.
Although uncommon, citrus fruit allergies are can cause food allergy symptoms like hives, swelling, asthma and flushed skin. If you experience any negative symptoms after eating limes, be sure to discontinue use immediately and talk to your doctor.
Additionally, despite the long list of lime nutritional benefits, it’s best to keep your intake in moderation. Limes contain a high amount of citric acid, meaning that overdoing it can start to erode the enamel on your teeth and cause increased sensitivity.
Finally, you should not apply limes or lime juice directly to your skin. This can increase your skin’s sensitivity to ultraviolet light and result in a condition called phytophotodermatitis, which can severely burn your skin.
