Here's a news report that's bound to make guys eat their fruits and vegetables:
Forget the oysters. Texas A&M scientists say watermelon contains ingredients that deliver Viagra-like effects to the body's blood vessels and may even increase the libido.(via HotAir) But here's a drawback. Most of the citrulline is found in the rind, so you can just throw out that red stuff with the seeds and eat the green, bitter rind. Mm, mmm!

Watermelon and some other fruits and vegetables contain phyto-nutrients, including lycopene, beta carotene and citrulline, which are compounds that produce healthy reactions in the body, Patil said.
Specifically, scientists believe it's the citrulline that has the ability to relax blood vessels, much like Viagra does.
Oh, yes, one other thing. "Watermelon may not be as organ-specific as Viagra," says Patil. It can do its work throughout your body.
So you should call your doctor if you can't bend your limbs after more than four hours.
