Subsequently, the researchers moved on to human trials. The experiment involved 20 men, with an average age of 27 years. For two weeks, half of them were given carrageenan in the morning and evening at a dosage of 250 mg, while the other group received a placebo.
The results showed that the intake of carrageenan resulted in increased permeability of the small intestine due to inflammation. Experts also noted that the worst outcomes were observed in individuals with a high BMI. They also exhibited reduced insulin sensitivity, as well as increased indicators of inflammation in the blood and brain.
“The results of the clinical observations are similar to what we observed in animals. In the long term, this may have negative health consequences and increase the risks of various inflammatory diseases. Given the widespread use of carrageenan in food products, we should take potential health risks seriously,” concluded the study's author, Robert Wagner.
His team will continue research in this area.
