Watermelon a day keeps Viagra away

ERECTILE COCKTAIL - Scientists in Texas, where everything is bigger, suggest that eating watermelons can give you Viagra-style erections. PROS. You’ll be going strong all summer. CONS. Watermelon is a diuretic (though this may be a pro for water sports enthusiasts) and they’re high in sugar — a low carb no-no.

Watermelons contain an ingredient called citrulline that can trigger production of a compound that helps relax the body’s blood vessels, similar to what happens when a man takes Viagra. [Yahoo]
