Common food ingredients like polysorbate 80, lecithin, and carrageenan interfere with microbes in the gastrointestinal tract, reports Elizabeth Grossman at Civil Eats:

Scan the fine print on almost any processed food in the grocery store and you’re likely to find emulsifiers: Ingredients such as polysorbate 80, lecithin, carrageenan, polyglycerols, and xanthan and other “gums,” all of which keep ingredients—often oils and fats—from separating. They are also used to improve the texture and shelf-life of many foods found in supermarkets, from ice cream and baked goods, to salad dressings, veggie burgers, non-dairy milks, and hamburger patties.
Now, a new study released today in the journal Nature suggests these ingredients may also be contributing to the rising incidence of obesity, metabolic syndrome, and inflammatory bowel disease by interfering with microbes in the gastrointestinal tract, known as “gut microbio.”
This news may surprise consumers, given the fact that emulsifiers are approved for use by the U.S. Food and Drug Administration (FDA), and appear in many foods otherwise considered “healthy,” including some in which their presence helps to reduce transfats and gluten, and many labeled organic and non-GMO.
