Carrageenan: Unveiling Potential Health Risks in the Human Body

**Carrageenan (E 407)**, widely used in the food industry as an emulsifier and thickening agent, is under scrutiny for its potential health impacts. Research led by DZD investigators, Prof. Dr. med. Robert Wagner and Prof. Dr. med. Norbert Stefan, focused on young, healthy men consuming carrageenan at doses two to three times the average US intake. Over two weeks, the study documented an increase in small intestine permeability, likely due to inflammation. Findings parallel animal studies where carrageenan promoted chronic inflammatory bowel disease, ulcers, and elevated blood sugar levels. Although insulin sensitivity—critical before type 2 diabetes—wasn't significantly impacted in the study participants, those with higher body weight showed a decline in insulin effectiveness, particularly affecting liver function. Notably, overweight participants displayed elevated inflammation markers and hypothalamus inflammation, a brain area crucial for sugar regulation and appetite. Prof. Stefan suggests that the impacts could be pronounced in older or overweight individuals, urging further research into this demographic. Prof. Wagner underscores the necessity to comprehend how carrageenan and similar additives influence human health, emphasizing informed consumption advice.
