WEDNESDAY JUNLY 2, 2008 (foodconsumer.org) -- Texas A&M University researchers suggested that eating watermelon may have some viagra-like effect to the body's blood vessels and may even increase libido.

The active ingredient in watermelon which is responsible for the effect is citrulline. The phytochemical can be converted in the body into an amino acid known as arginine, which is known to relax blood vessels much like viagra does.

“Arginine boosts nitric oxide, which relaxes blood vessels, the same basic effect that Viagra has, to treat erectile dysfunction and maybe even prevent it,” said Dr. Bhimu Patil, director of Texas A&M’s Fruit and Vegetable Improvement Center in College Station.

Another beneficial ingredient in watermelon is lycopene, an anti-oxidant that protects the human heart, prostate and skin health.   But without much fat in the melon, adsorption is not expected to be good.

Arginine is found high in peanuts. Vitamin C also helps generate nitric oxide.   So men who desire to have a boost in their performance in the bedroom should not restrict themselves to eating water melon only. Instead, they should eat lots of raw peanuts and vitamin C. Viagra should be the last resort.
