COMPLAIN COMPLAIN COMPLAIN!! I’m guilty of it. We are all guilty of it at some point but we have to when it’s the right time to complain or not. But you know what’s better than complaining? THE TRUTH! Spreading fact-based truths about things rather complaining is more helpful than… you know… complaining! Let’s talk the TRUTH about CARRAGEENAN! And lets do it with some facts! Let’s dive in and I’ll see you in the COMMENTS!!

A lot of the controversy surrounding carrageenan has actually come from poligeenan, but has been mistaken for carrageenan (carrageenan still isn’t off the hook, though)

Carrageenan is a natural substance found in, and extracted from, seaweed, whereas poligeenan is made via a chemical process using high temperatures (used in medical imaging)

Poligeenan used to be referred to as “degraded carrageenan,” hence the confusion

Carrageenan Studies

A review of carrageenan in Critical Reviews in Toxicology, entitled, “A Critical Review of the Toxicological Effects of Carrageenan and Processed Eucheuma Seaweed on the Gastrointestinal Tract” found that Carrageenan is not degraded to any extent in the gastrointestinal tract and is not absorbed from it in species examined, such as rodents, dogs, and non-human primates.

And has also been found to NOT be carcinogenic (which is what a lot of the claims surrounding it are)

https://pubmed.ncbi.nlm.nih.gov/12389870/

Carrageenan & Gut Health

A study from Food and Cosmetics Toxicology found that poligeenan does induce diarrhea, hemorrhage, and ulcerations (in monkeys)

https://www.sciencedirect.com/science/article/abs/pii/S001562647380327X

However, the review of carrageenan from Critical Reviews in Toxicology, mentioned above, stated that carrageenan has produced intestinal damage in some animal studies

Human Studies

A study published in The Journal of Nutrition found that human epithelial cells that were exposed to carrageenan experienced increased cell death and reduced cell proliferation

https://academic.oup.com/jn/article/138/3/469/4670224

Another study, published in Biochimica et Biophysica Acta, found that when intestinal epithelial tissue were exposed to carrageenan it resulted in activation of NF-κB

https://pubmed.ncbi.nlm.nih.gov/22579587/

This study, from Nutrition and Healthy Aging, looked at the effects of the no-carrageenan diet on ulcerative colitis disease activity (ulcerative colitis is an inflammatory bowel disease (IBD) that causes long-lasting inflammation and ulcers (sores) in your digestive tract)

Three patients who received carrageenan-containing capsules relapsed, and none of the patients who received placebo-containing capsules relapsed

Lab tests showed increases in Interleukin-6 between the beginning and the end of study participation in the carrageenan-exposed group, but not in the placebo-group

Researchers concluded that carrageenan intake contributed to earlier relapse in patients with ulcerative colitis in remission and that restriction of dietary carrageenan may benefit patients with ulcerative colitis

So those with stomach issues are seemingly more susceptible
