The Surprising Health Benefits of Lemon

The Top Benefits of Lemon Nutrition (Plus How to Use Lemons)

Lemon 

A lot of people think of lemon as nothing more than a simple garnish served alongside water at restaurants or a popular flavor for candies and desserts. Did you know that the lemon is actually loaded with vitamin C, antioxidants and health benefits?

It’s true — lemon nutrition benefits range from reducing the risk of kidney stones to killing off cancer cells, whether we’re talking lemon water, lemon essential oil or just the tart fruit itself.

Plus, the potential uses for lemons extend way beyond the kitchen. Lemons can be used for just about everything, from polishing furniture to adding extra shine to hair and improving skin health.

Although it’s unclear where lemons actually originated from, it’s believed that they are native to India, China or Burma.

They entered Ancient Rome by the second century A.D. but were still not widely used or cultivated in Europe until later. In fact, it wasn’t until around 1000 A.D. that lemons actually began to spread to the Mediterranean region.

In the 18th century, scurvy became a major cause of death for British sailors. Scurvy, a condition caused by vitamin C deficiency, can lead to symptoms like bruising, bleeding gums and fatigue.

Scientist James Lind is credited with conducting experiments on board a naval ship in 1747, demonstrating that lemon nutrition could help ward off scurvy.

Today, lemons are widely used around the world to add a zip of flavor to recipes and are loved for their delicious fragrance and aroma. Although they can be found in most corners of the globe, India, Mexico and China are leaders in lemon production.

Benefits

1. Enhances Immunity

Lemons are a good source of vitamin C, an important nutrient that’s been linked to increased immune health. In fact, gram for gram, there is about the same amount of vitamin C in lemon vs. orange nutrition.

Not only that, but lemons are also loaded with antioxidants that can help fight inflammation and promote improved immunity.

A review in the Annals of Nutrition & Metabolism noted that getting enough vitamin C could help reduce the duration and severity of respiratory tract infections. Vitamin C may also help prevent malaria, diarrhea and pneumonia, and it could even improve the outcomes for those suffering from these conditions.

Lemons are also high in antioxidants. Antioxidants have been shown to protect your immune cells by neutralizing harmful free radicals and keeping your body free of infections caused by bacteria or viruses.

2. Promotes Heart Health

Heart disease is the leading cause of death in the United States, and it’s estimated that 92.1 million Americans have some form of heart disease.

One of the most impressive lemon nutrition benefits is its effect on heart health. Thanks to its high vitamin C content, including a few servings of this sour fruit in your diet per week could help keep your heart healthy and strong.

For instance, one study from the Harvard School of Public Health in Boston looked at the diets of 126,399 adults over a period of eight to 14 years and found that each serving of fruits and vegetables was associated with a 4 percent decreased risk of coronary heart disease. Interestingly enough, leafy green vegetables and vitamin C fruits and veggies, like lemons, had the greatest impact.

Another study published in the Journal of Nutrition and Metabolism in 2014 indicates that both walking and eating lemons every day were associated with a decrease in blood pressure.

To really optimize heart health, include a good variety of fruits and vegetables in your diet, including lemons, and pair with a healthy and active lifestyle.

3. Helps Fight Cancer

Lemons are packed with antioxidants and cancer-fighting compounds, so it’s no wonder that a slew of studies have found that lemons may be effective in killing off cancer cells.

A test-tube study in Saudi Arabia, for example, showed that lemon fruit extract helped kill breast cancer cells. Similarly, another test-tube study in 2015 indicated that the components in lemon juice successfully inhibited the growth of several types of cancer cells.

Lemons also contain compounds like hesperidin and d-limonene. These have both been shown to have cancer-preventing properties.

Thanks to all these powerful properties in lemon nutrition, lemons are among the top cancer-fighting foods around.

4. Prevents Kidney Stones

If you suffer from kidney stones, incorporating a serving or two of lemons into your diet may be able to help. This is because lemons contain citric acid. Citric acid has been proven to increase urine volume and aid in kidney stone prevention.

One small study published in the Journal of Urology treated 11 participants with lemonade therapy for nearly four years. Researchers found that stone formation dropped significantly, from an average of one kidney stone per year down to just 0.13 per year.

Another study showed that treating kidney stone patients with lemon juice increased urinary citrate levels and decreased the amount of calcium in the urine. This suggests that lemon juice may be a potential alternative treatment for relieving kidney stone symptoms.

5. Increases Iron Absorption

Iron is an incredibly important mineral for your body. It is one of the main components of hemoglobin, which is found in the red blood cells and helps provide the body with the oxygen that it needs.

There are many groups of people at risk for iron deficiency. Vegans and vegetarians, for example, consume a type of iron that is not as well-absorbed by the body. Additionally, women of reproductive age are at a higher risk due to blood loss through menstruation.

Research shows that vitamin C, which is plentiful in lemons, can help enhance iron absorption to prevent conditions like iron-deficiency anemia. One study even showed that taking 100 milligrams of vitamin C with a meal increased iron absorption by 67 percent.

Limes, oranges, peppers, berries and broccoli are some additional vitamin C foods that you can include in your diet to boost iron absorption.

6. Improves Skin Health

Lemons may act as an anti-aging food and be able to help keep your skin healthy and glowing thanks to their antioxidant content. Antioxidants help fight off free radicals and prevent oxidative damage, which accounts for the many benefits of lemon water for skin.

The buildup of free radicals contributes to the aging process, resulting in changes like wrinkles, age spots, dryness and decreased elasticity. Researchers believe that antioxidants could be an effective way to slow aging and improve skin health.

One study in Turkey found that patients with acne have increased levels of oxidative stress. Researchers suggested that using antioxidants could be beneficial in combination with traditional treatment.

For best results, try applying a bit of lemon juice to your skin or mixing with your favorite skin care products. Besides lemons, other ingredients that should be staples in your natural skin care routine include tea tree oil, coconut oil and avocado.

7. Boosts Weight Loss

Swapping your soda or juice for a glass of cold lemon water benefits weight loss by helping you cut calories without sacrificing flavor.

To compare, one cup of orange juice contains 112 calories and nearly 26 grams of carbs. On the other hand, there are just six calories in lemon water without sugar.

Plus, while there are a good amount of carbs in lemon juice, diluting it with water significantly slashes the carbs in lemon water, dropping it down to just two grams per serving.

Theoretically, if you traded one cup of juice or soda for one cup of lemon water every day for a year, you would save nearly 39,000 calories. That means that you could lose up to 11 pounds even without making any other changes in your diet.

While lemon benefits weight loss, it should be combined with a nutritious diet and healthy lifestyle to really get the results that you want in terms of weight loss.

8. Antioxidant Powerhouse

Not only do the antioxidants present in lemon help improve skin health and support healthy aging, but they have exhibited radical scavenging activity and protection for the body from DNA mutations that lead to disease.

Lemon contains powerful flavonoids, including quercetin, luteolin, apigenin and hesperidin. Quercetin, for example, helps reduce damaging inflammation, may work to relieve allergy symptoms and helps fight pain.

Lemon Nutrition Facts

Lemons contain a good amount of fiber and vitamin C — plus lemon nutrition has a few other micronutrients as well.

One large lemon without the peel contains approximately:

• 24 calories
• 8 grams carbohydrates
• 0.9 gram protein
• 0.3 gram fat
• 2.4 grams dietary fiber
• 44.5 milligrams vitamin C (74 percent DV)
• 116 milligrams potassium (3 percent DV)
• 0.5 milligram iron (3 percent DV)
• 0.1 milligram vitamin B6 (3 percent DV)

Additionally, lemons also contain a small amount of thiamin, folate, pantothenic acid, calcium, magnesium and copper.

Lemons vs. Limes

Lemons and limes are used interchangeably in many instances, and when it comes to taste, it’s easy to get these two fruits mixed up. Both have a sour and tart flavor that adds the perfect amount of zing to drinks and recipes.

However, there are quite a few differences between the two fruits, starting with their appearance. Limes are bright green while lemons are vibrant yellow.

Additionally, limes are typically slightly smaller than lemons. Limes tend to be less sour and have a smoother taste as well.

Both are used similarly, though, and can often be swapped in many recipes.

When it comes to nutrition, the benefits of lime are not quite as impressive as those of lemons. Lime nutrition contains just over half of the amount of vitamin C and contains slightly more carbs and less protein per gram.

The lemon nutrition profile is also a bit more extensive, boasting a higher amount of many nutrients, such as folate and vitamin B6.

Uses/Recipes

Lemons are grown in areas with warmer climates and can be picked once they are firm, yellow or yellow-green and two to three inches in size.

You can also find lemons at most grocery stores in the produce aisle. Look for lemons that are bright, heavy and free of wrinkles on the skin.

Once you stock up on this tasty fruit, there are a wide range of potential lemon uses for you to enjoy. Add lemons to drinks or water to amp up the flavor, use them in desserts or baked goods, or even kick up your next main course, like a fish entree, with a squeeze of fresh lemon.

Pair with some health-promoting herbs like thyme, rosemary or lemon balm for even more flavor and health benefits.

Lemon can be used outside of the kitchen as well. It can be added to laundry to whiten and brighten clothing, used as a natural home cleaner and polish, or even applied to the hair to add extra shine.

You can also try adding a few drops of lemon oil to your laundry or diffuser for a fresh scent.

Risks and Side Effects

For most people, lemons can be consumed and enjoyed with minimal risk of side effects. However, some people may want to consider limiting their intake.

Citrus fruit allergies are uncommon but have been reported and can cause food allergy symptoms like hives, swelling, asthma and flushed skin. If you experience any negative symptoms after eating lemons, be sure to discontinue use immediately and talk to your doctor.

Plus, although the lemon nutrition profile is pretty impressive, it is definitely possible to overdo it. Because of the citric acid found in lemons, eating too many can cause the enamel on your teeth to erode, resulting in increased sensitivity.

Finally, applying lemon directly to your skin can increase sensitivity to UV rays, so be sure to wear sunscreen or keep sun exposure in moderation to avoid a sunburn.
