SUNDAY July 6, 2008 (foodconsumer.org) -- Researchers from
the Texas A&M University have done a great PR stunt and drawn an unusually
tense attention from the media to the possible benefits of watermelon to men's
What the researchers touted is the presence of a precursor
called citrulline of arginine, a common natural amino acid, in watermelon.
Arginine has a range of physiologic functions
in the body and some help maintain sexual health and promote sexual
Citrulline is abundantly found in the rind of watermelon.
Unfortunately many people do not eat that part of watermelon and it's unlikely
they get the amount of citrulline to have an effect.
In the body citrulline is converted into arginine.
One significant function of the amino acid is
to act as a precursor in the body for nitric oxide, a gas molecule that relaxes
arteries, small blood vessels and ease blood flow, which is known to be
important for sexual performance.
According to media reports, six or seven slices of
watermelon need to be consumed to have enough citrulline to result in an
Plus, the rind needs to be eaten
to have the highest intake of citrulline.
In reality, the amount of watermelon needed to have an effect is so much
that men would be busier in bathroom than bedroom.
Arginine is a powerful compound though.
Studies have suggested that taking an arginine
supplement for weeks or months would significantly increase the production of
sperm and drastically improve erection.
The effective doses range from 2 to 5 grams per day, as studies have
Arginine is present naturally in wheat germ and flour,
buckwheat, granola, oatmeal, nuts (coconut, pecans, cashews, walnuts, almonds,
Brazil nuts, hazel nuts, pine nuts, and peanuts), seeds (pumpkin, sesame,
sunflower), chick peas, cooked soybeans and chocolate, according to Wikipedia.
A scientist affiliated with foodconsumer.org suggested that
instead of eating watermelon, those who want to have a boost in their bedroom performance
may consider eating peanuts and other foods that contain high levels of
In the meantime, they should
also eat high amounts of vitamin C and if possible some omega-3 fat.
