Health benefits of eating Watermelon

Loaded with potassium, magnesium, lycopene and amino acids, watermelon is one of the most nutritious summer fruits. In fact, it’s often referred to as “natural Viagra.” Some studies suggest that it may help with erectile dysfunction and boost sexual health.

 

1. It soothes sore muscles.

According to research, drinking watermelon juice before a hard workout helped reduce athletes’ heart rate and next-day muscle soreness. That’s because watermelon is rich in an amino acid called L-citrulline, which the body converts to L-arginine, an essential amino acid that helps relax blood vessels and improve circulation.

The study’s seven participants, all men, were given 17 ounces (500 mL) of either natural watermelon juice, watermelon juice enriched with additional citrulline, or a placebo drink an hour before their workouts. Interestingly, the natural juice was just as effective as the enriched juice. The researchers also determined that intestinal cells can absorb more citrulline from watermelon juice than from citrulline supplements, especially when the juice is unpasteurized.




2. It helps heart health.

Postmenopausal women experienced improved cardiovascular health after six weeks of taking commercially available watermelon extract supplements containing citrulline and arginine, according to a study published earlier this year by Florida State University physiologist Arturo Figueroa.

And in a 2012 study—also led by Figueroa—such supplements helped alleviate high blood pressure in obese, middle-aged adults. (Not surprisingly, he’s received two grants from the Watermelon Promotion Board.)

3. It could be a natural Viagra.

Improved circulation can benefit more than just the heart, as at least one watermelon researcher has pointed out. But you’d probably have to eat an awful lot to achieve the desired effect–and eating too much could cause unfortunate side effects, since watermelon has long had a reputation as a natural diuretic.

This summer fruit is a powerhouse of nutrition. Some studies point out that watermelon benefits for men may include a better sex life and improved prostate health. These effects may be due to its high content of citrulline, arginine and lycopene.

According to a January 2017 review published in Current Opinion in Clinical Nutrition and Metabolic Care, watermelon may help increase arginine levels in the bloodstream and reduce blood pressure in adults with prehypertension or hypertension. Researchers attribute these benefits to l-citrulline, a non-essential amino acid that is converted to arginine in the body.

Citrulline increases vasodilatation and may improve cardiometabolic health, as reported in a July 2018 research paper featured in the journal Nutrients. Furthermore, it may protect against endothelial damage, reduce inflammation and decrease arterial stiffness.

A February 2017 study published in the journal Andrology suggests that l-citrulline may play a role in men’s sexual health. Male subjects with erectile dysfunction (ED) had lower levels of citrulline, arginine or both. These findings indicate that increasing levels of these amino acids may help improve ED symptoms.




Another study, which had only 20 participants, supports this theory. Researchers have found that combining L-citrulline and trans-resveratrol may improve erection firmness, sexual satisfaction and the ability to maintain erections in men with ED. The results were published in the December 2018 issue of Sexual Medicine. The study was small, though, so further investigation is needed.

Based on the current evidence, it’s fair to say that watermelon won’t replace Viagra anytime soon. However, it may improve men’s sexual health, among other benefits. Lycopene, one of its key antioxidants, helps reduce oxidative stress and lipid peroxidation, which in turn, may boost male fertility.

4. It’s rich in vitamins and minerals, but low in calories.

Given its name, you might assume the fruit has little nutritional value—and it is more than 90 percent water. But a 10-ounce (300-mL) wedge of watermelon packs in about one-third of the recommended daily value of vitamins A and C, as well as a modest amount of potassium.

5. It could even combat cancer.

Watermelon is among the best dietary sources of lycopene, an antioxidant linked to both the prevention and treatment of prostate cancer, although scientists are still investigating the details of that connection.
