Watermelon is a fruit full of many important nutrients. Many may not realize, however, that is it completely safe to eat the rind, which is the green skin that keeps all that water-logged delicious fruit safe.

Watermelon may be one of the most appropriately named fruits. It’s a melon that’s 92 percent water. It’s also got a healthy amount of vitamins A and C, potassium, magnesium, and other important nutrients.

The most popular part of the watermelon is the pink flesh, but like its cousin, the cucumber, the whole thing is edible. This includes the green scraps that usually end up in the compost bin.

Here are just a few reasons why you should consider not throwing it out.

No, watermelon rind isn’t nature-powered Viagra, but some research shows that it may help men with mild to moderate erectile dysfunction. Its libido-boosting powers come from the amino acid citrulline, which is concentrated in the rind.

One study showed that taking L-citrulline supplements can improve erections without many of the potential side effects associated with Viagra.

Try spritzing your watermelon rind with lemon juice and sprinkling some chili powder on it. Both additives also are good for your heart, and your, ahem, other love organ.

Besides improving your performance in bed, citrulline might improve your next athletic performance as well. However, most evidence for this is anecdotal.

Citrulline promotes the dilation of blood vessels. One study suggests that citrulline supplements improve oxygen delivery to muscles, potentially improving exercise performance.

To get it naturally, try pickled watermelon rinds, an old-fashioned treat in the southern states.

If your doctor instructed you to lower your blood pressure, try eating watermelon — rind and all. Some research has shown that watermelon extract supplements are able to help obese adults control their blood pressure.

However, citrulline supplements are likely more effective. Most studies suggest citrulline supplements reduce blood pressure in people with hypertension.

Watermelon is also a potential diuretic, which often is prescribed for people with high blood pressure. Try freezing whole watermelon slices for a nice treat on a summer’s day.

Another benefit of watermelon rind is that it’s a rich source of fiber. A diet high in fiber has a whole host of health benefits, including the following:

  • Fiber helps maintain regular bowel movements and may help reduce the risk of developing diseases of the colon.
  • Fiber can help lower cholesterol and blood sugar levels.
  • Foods with fiber fill you up faster, helping achieve and maintain a healthy weight.

Only about 5 percent of adults in the United States get the recommended daily value of fiber. Consider eating the rind to boost your fiber levels!

Next time you slice into a watermelon, consider keeping the rind. It’s a quick and tasty way to improve your overall health.
