Red 40 food dye in Jell-O, Doritos, and more causes ‘striking and alarming’ disease: IBD Study


New research showed a common red food coloring is harming people’s gut health, increasing their risk of inflammatory bowel diseases.

The study, conducted by researchers out of McMaster University and published this week in the Nature Communications journal, found that the food coloring additive, known as Allura Red, FD&C Red 40, or Food Red 17, can raise the risk of inflammatory bowel disease, Crohn’s disease, and ulcerative colitis.

The red dye is often found in candies, soft drinks, dairy products, cereals, and snack foods, including Doritos, multiple brands of jello, and even chocolate pudding and some pickles.

This is interesting, although it should be noted this is a study in mice not humans. It should also be noted that the increase in bowel inflammation was observed in the mice that were fed a constant diet of the dye. The mice that got an occasional exposure, which more closely mimics human consumption of foods containing the dye, did not show an increase in bowel inflammation. Still, it's something to be aware of and perhaps something to look out for when reading the ingredient labels of processed foods.
And who knows what any normal human will consume on a regular basis though? we've got people who are vegetarians for decades, surely there are plenty of people drinking red kool aid 3 days a week for 10 years, and on the other days they are eating red tamales candy the other 3, thats probably pretty common, but may not be enough alone to cause IBD. Plenty of evidence now showing being a vegetarian is not all that healthy, cognitive decline happens sooner, and probably heart disease.
This is really interesting. There's definitely a possibility that this is a real problem for humans, too. The study also found that mice with the lack of a certain enzyme related to serotonin production didn't get colitis when exposed to the dye.
