8 Foods Linked to Inflammation
What's in it: Monosodium glutamate, or MSG
The science: When mice were injected with MSG, they developed inflammation throughout their bodies along with increased abdominal fat and type 2 diabetes. Those are dramatic results, and, of course, this study, published in the Journal of Autoimmunity, wasn't done on humans, but the researchers concluded that their findings should prompt a reexamination of whether it's really safe for MSG to be in our food supply.
One more thing: MSG can be found in chips, in addition to some broths. The FDA mandates that any added MSG has to be included on a product's ingredient list as monosodium glutamate. The bad news is that MSG also occurs naturally in ingredients like protein isolate and soy extract, and since the list of foods with natural MSG is long, it can be difficult to do a thorough check of the label before you buy something. Your safest bet when buying foods that might have MSG is to look for "No MSG" on the packaging.
