Low doses of two commonly used dietary emulsifiers—carboxymethylcellulose and polysorbate-80—are reported to induce low-grade inflammation, metabolic disorders and increases in body weight in mice. These emulsifiers also promote colitis in mice that are susceptible to this disorder. Interestingly, changes in the gut microbiota were both necessary and sufficient to induce the metabolic alterations.
