Carrageenan not toxic to intestinal cells: study

Carrageenan is a common food additive used for its gelling and thickening properties. It has become a controversial ingredient over the last five years.

A study in the upcoming October issue of Food and Chemical Toxicity examined the effects of carrageenan on cell permeability, cytotoxicity, and cytokine gene expression in human intestinal and hepatic cell lines.

Three common forms of the food additive carrageenan were tested in vitro.

The carrageenan tested were subjected to advanced identity and purity testing.

Carrageenan was evaluated in three human intestinal cell lines.

Endpoints included permeability, cytotoxicity, and induction of cytokines.

Carrageenan was negative in all endpoints evaluated.

In conclusion, carrageenan was not absorbed, and was not cytotoxic. It did not induce oxidative stress, and did not induce proinflammatory proteins.

Thank you for posting this as I was wondering with all the controversy that it could be a problem. I now will not worry about the small quantities in my favorite coconut ice cream.
