Impaired glucose intolerance
- In 2012 Diabetologia published an animal study which found that mice given carrageenan in their drinking water had impaired glucose tolerance and increased insulin resistance which may contribute to the development of diabetes.
- In 2003 the Asian Pacific Journal of Nutrition published a study in which carrageenan was incorporated into 4 food items and given to volunteers for an 8-week period. Compared to a controlled period where subjects consumed their normal diet, carrageenan was associated with a decrease in triglycerides and an increase in HDL cholesterol.
- In 2016 BMC Complementary and Alternative Medicine published an in vitro study which found that carrageenan slowed the progression of cervical cancer cells.
