Watermelon is not only a staple food but it also the juicy fruit has ingredients that deliver Viagra-like effects to the body’s blood vessels and may even increase libido. Watermelon may not be as organ specific as Viagra but it’s a great way to relax blood vessels without any drug side-effects.”

It provides natural enhancers to the human body. List of its very important healthful benefits grows longer with each study. It helps in relaxing blood vessels, much like Viagra does.

Scientists know that when watermelon is consumed, citrulline is converted to arginine through certain enzymes. Arginine is an amino acid that works wonders on the heart and circulation system and maintains a good immune system.

“The citrulline-arginine relationship helps heart health, the immune system and may prove to be very helpful for those who suffer from obesity and type 2 diabetes. Arginine boosts nitric oxide, which relaxes blood vessels, the same basic effect that Viagra has, to treat erectile dysfunction and maybe even prevent it.”

While there are many psychological and physiological problems that can cause impotence, extra nitric oxide could help those who need increased blood flow, which would also help treat angina, high blood pressure and other cardiovascular problems.

The benefits of watermelon don’t end there, Arginine also helps the urea cycle by removing ammonia and other toxic compounds from our bodies.
Citrulline, the precursor to arginine, is found in higher concentrations in the rind of watermelons than the flesh. As the rind is not commonly eaten.

Deep red varieties of watermelon have displaced the tomato as the lycopene king. Almost 92 percent of watermelon is water, but the remaining 8 percent is loaded with lycopene, an anti-oxidant that protects the human heart, prostate and skin health.

“Lycopene was historically thought to exist only in tomatoes but now we know, it’s found in higher concentrations in red watermelon varieties.”

“They store much better uncut if you leave them at room temperature. Lycopene levels can be maintained even as it sits on your kitchen floor.

Once you cut it, refrigerate. And enjoy.”
