This past weekend, PepsiCo unveiled a fat-blocking drink that it is set to release in Japan. The new-beverage, Pepsi Special, contains a proven fat-fighting ingredient called dextrin and is primed to target the country’s lucrative market of “young, health-conscious men,” says Akito Fujita at ABC News. In the U.S. dextrin is sold as a supplement called Benefiber, which works by absorbing water as it moves through our intestines, says James Hamblin at The Atlantic. “That promotes movement of food through the bowel and contraction of the bowel wall itself (bowel movement, if you will.)” PepsiCo launched is product on Tuesday, as a fat-blocking health drink.
