Food Additive Might Disrupt Gut Health
Carrageenan, a common food additive used as an emulsifier and thickener, has already been linked to chronic inflammatory bowel disease, ulcers, and increased blood sugar levels in animal studies. Now, a clinical study by German researchers reveals more about its effects on the human intestine and sugar metabolism. The study involved 20 healthy young men who consumed carrageenan at levels two to three times the average U.S. intake for two weeks.
Results showed increased small intestine permeability and reduced insulin sensitivity in participants with higher body weight. Markers of inflammation were also observed in volunteers who were overweight. The researchers highlight the need for further studies, particularly in older or overweight people, to assess all the potential health risks of carrageenan consumption.
