The food additive monosodium glutamate (MSG) could lead to obesity. Recent research found that people who eat more MSG are more likely to be overweight or obese. What’s more, the link between high MSG intake and being overweight held even after accounting for the total number of calories people ate.

MSG is a widely used food additives. It is often present in processed foods although it is frequently not clearly labeled. MSG is frequently seen hiding behind such innocent-sounding names as hydrolyzed protein,
vegetable protein, soy protein isolate, soy protein concentrate, whey protein, and natural flavoring, spices, enzymes, autolyzed yeast extract, stock, broth and carrageenan. If MSG was as benign as the food industry says it is, why do they have to disguise the name.

Reuters reports:

“In the latest research, published in the American Journal of Clinical Nutrition, He and his colleagues followed more than 10,000 adults in China for about 5.5 years on average.

The researchers measured MSG intake directly by before-and-after weighing of products, such as bottles of soy sauce, to see how much people ate. They also asked people to estimate their intake over three 24-hour periods.

Men and women who ate the most MSG (a median of 5 grams a day) were about 30 percent more likely to become overweight by the end of the study than those who ate the least amount of the flavoring (less than a half-gram a day), the researchers found. After excluding people who were overweight at the start of the study, the risk rose to 33 percent.”
