MSG may promote weight gain?

"Research suggest that MSG(monosodium glutamate),flavor enhancer in some food,may be playing a role in obesity epidemic "reports The Washington Post.

International team of researchers gather some evidence from 750 middle-aged peasants in three rural villages in China,where most people prepare their own food at home,making it possible to tease out any possible effects of MSG.It's the first study to examine MSG and weight in humans.Researchers found out that heavy MSG users were nearly three times overweight than non-users.That's after the researchers took into account differences in physical activity and total caloric intake.

This research was led by Ka He ,an assistant professor of nutrition and epidemiology at the University of North Carolina School of Public Health.According to him, it still remains unclear how MSG might promote weight gain. But animal studies suggest that MSG might affect the hormones leptin and adipsin, which help regulate weight. Even though the new study involved only Chinese, he says there's no reason to think MSG would affect other ethnicities any differently.He cautions that more research is needed to establish whether there really is a cause-and-effect relationship between MSG and weight, but notes that the amount of MSG being used around the world has been increasing.
