Bananas instead of Sports Drinks
Gatorade for Athletes
Bananas are as effective as Gatorade in providing nutritional support and
hydration to athletes during prolonged and intensive exercise, according to a
study in the journal PLoS
Powerade is the official Olympic
sports drink. The bottles are everywhere, even in the hands of America's
biggest stars, from Michael Phelps to Chris Paul.
Besides the stars,
another essential part to marketing in the $7-billion worldwide sports drink
game is science. In the industry, Gatorade, made by Pepsi,
is the market leader by far.
But just as the
Olympics games began in London a group of researchers at England's Oxford
University published a study of the marketing claims and the science behind
them in BMJ, the British medical journal.
that much of the science has not been well done," Dr. Matthew Thompson,
senior clinical scientist at Oxford, told ABC News. "[It] could have
easily been done much more rigorously so we'd actually know whether or not
these products work."
researchers, independent M.D.'s and clinical scientists, looked at more than
400 advertising claims for sports drinks and could not find scientific backing
for more than half of them. They characterized many of the rest as flawed
a lot of industry sponsored scientists to do the research, which makes us
suspicious," said Thompson. "There's nothing wrong with having a
scientific study funded by a company, and this happens all the time with
pharmaceuticals and many products. I think what's key is that the science that
is done is of high quality."
