Lemons – A Brief

Lemons are the fruits of a small evergreen tree native to South Asia. They are a cross between lime and citron and are thought to have originated at the base of the Himalayas.

These yellow fruits are used the world over for culinary purposes and otherwise. The juice of a lemon contains 5% to 6% citric acid and has a pH of 2.2. This is what is responsible for its distinctive sour taste, making it a hit in food preparations.

But that’s not all – lemon has been used as extensively for its beneficial properties as for its taste. In this post, we will discuss the various ways this ellipsoidal fruit can better your health and, as a consequence, your life.

How Can Lemons Benefit Your Health?

1. Lemons Boost Your Heart Health

Lemons are among the richest sources of vitamin C (1). Studies show us that fruits and vegetables, especially those rich in vitamin C, can prevent coronary heart disease (2).

Studies also found that lemon ingestion and walking lowered blood pressure levels (3).

Citrus fruits, including lemons, contain essential flavonoids that help in the treatment of atherosclerosis. These compounds blunt the inflammatory responses in the body that can lead to cardiovascular disease (4).

2. May Help Control Weight

Some research shows that the polyphenols in lemons help suppress diet-induced obesity (5). These polyphenols were shown to suppress body weight gain and body fat accumulation.

Another study found that the lemon detox diet (organic maple and palm syrups, and lemon juice) helped reduce body fat – thereby reducing body weight and cutting the risk of cardiovascular disease (6).

Some theories also suggest that drinking hot lemon water right in the morning can boost weight loss.

However, most studies in this regard have been performed on animals. More research on humans is warranted.

3. Help Treat Kidney Stones

Lemons contain citrate, a chemical that prevents the formation of kidney stones (7). Citrate also breaks down bigger stones, allowing them to pass easily through urine.

In a study, drinking four ounces of reconstituted lemon juice in two liters of water every day decreased the rate of stone formation (8). Citrate achieves this by binding to calcium and blocking stone formation (9).

4. Can Treat Anemia

The vitamin C in lemons promotes the absorption of iron from plant foods, thereby treating anemia (10).

Your gut absorbs the iron from animal sources more easily as compared to plant sources. The vitamin C in lemons can help in improving overall iron absorption.

5. Aid Cancer Treatment

Some observational studies found that individuals consuming citrus fruits, like lemons, had a lower risk of pancreatic cancer (11).

Similar findings have been observed in the case of stomach cancer(12).

Some experts hypothesize that the anticancer properties of lemons can be attributed to their flavonoids (13).

Certain animal studies found that D-limonene, a compound in lemon oil, may have anticancer properties (14).

6. May Boost Digestive Health

Some theories suggest that drinking lemon water in the morning can aid digestion and relieve constipation.

Drinking lemon water when you wake up may keep your digestive system moving.

We need more research on this, though. Some also claim that the detoxifying properties of lemons can boost digestion.

7. Lemons Promote Immunity

The vitamin C in lemons can promote immunity in humans. Studies show that this vitamin can reduce the duration of a cold, an ailment that occurs due to a weak immune system (15).

Lemons can also have protective effects against asthma. One study shows that individuals with asthma and other bronchial issues benefited from the consumption of vitamin C (16).

Mixing lemon with honey may also help treat cough.

8. Enhances Liver Health

Lemons possess antioxidant properties that may enhance liver health. In one study, lemon juice showed protective effects on mice with alcohol-induced liver injury (17).

In another study, citrus fruit oil was found to improve hepatotoxicity in chickens fed with a diet containing aflatoxin (a potent hepatocarcinogen) (18).

9. May Help Fight Acne

Theories suggest that the citric acid in lemons can have a drying effect on the skin, reducing surface sebum levels. The citric acid may also have antiseptic properties, which may eliminate the acne-causing bacteria.

Studies show that vitamin C has anti-inflammatory properties and can be used for treating conditions like acne vulgaris (19).

Conversely, lemons may also cause side effects in some individuals. These include issues like burning, stinging, itching, and redness. Hence, use lemons with care. Do a patch test before use. Also, check with your doctor.

These are the ways lemons can benefit you. Lemons have also been used in a few other ways, though there is no concrete research to support their use. Anecdotal evidence supports these benefits – which we shall cover now.

10. Lemons May Reduce Wrinkles

This may have to do with the vitamin C in lemons. The nutrient boosts collagen and may help reduce wrinkles.

11. May Help Lighten Underarms

Though we don’t know how lemons can help achieve this, some anecdotal evidence suggests it works.

Cut thick slices of lemon and rub them on your underarms. Leave the juice on for 10 minutes and then wash your underarms with cool water. Pat them dry and apply moisturizer.

12. May Lighten Stretch Marks

There is very little information on how lemons can help lighten stretch marks. But anecdotal proof tells us they may work.

You can slice open a lemon and add the juice to a bowl. Apply this juice, in circular motions, on your stretch marks. Ensure the juice soaks into your skin. This may take about 5 to 10 minutes. You can then wipe it off.

Some theories suggest that the fruit acids in lemons can bleach the skin and reduce the appearance of stretch marks.

After wiping off the lemon juice, you can apply an emollient (like cocoa butter) to the stretch marks. This can soothe and soften the skin and reduce their appearance.

13. May Aid Eczema Treatment

Applying lemon juice to the affected regions may offer some relief. Apply it twice to thrice a day, allowing it to stay for 10 to 15 minutes each time.

But since there is very little information regarding this aspect, we suggest you speak to your doctor.

These are the various benefits lemons have in store for you. Yes, we know lemons are one of the richest sources of vitamin C. But there are other nutrients these fruits contain that can contribute to your health. What are they?
