Red food coloring linked to inflammatory bowel disease (IBD)

Skittles, Doritos, Gatorade, Jell-O, Fruit Loops, and many other top-selling food products contain a synthetic dye called Allura Red AC, which, if consumed too often, can increase the likelihood of inflammatory bowel disease (IBD), including Crohn’s disease. disease and ulcerative colitis.

A small study involving lab mice suggests that frequent and long-term exposure to the dye (also called FD&C Red 40 and Food Red 17) damages gut health and promotes inflammation.

Recently published in The nature of communicationResearch has found that the additive directly disrupts the gut barrier (which helps prevent bacteria from entering) and increases the production of serotonin, a hormone and neurotransmitter found in the gut. This response alters the gut microbiome, leading to an increased susceptibility to inflammatory bowel disease, according to the report.

“What we found is surprising and alarming because this common synthetic food coloring is a possible dietary trigger of IBD,” said lead study author Waliul Khan, PhD, who researches gastrointestinal inflammation at McMaster University in Hamilton, Ontario.
