Carrageenan is a natural carbohydrate obtained from edible red seaweeds. Carrageenan supposedly non-toxic is found in any kind of processed foods including infant formulas. Carrageenan is utilized in processed foods as a thickener and stabilizer. It render the food more palatable and appealing through interaction with other substances in the food.1 Scientists studied carrageenan for decades, and revealed that it could induce carcinogenic effects on health. The European Commissionâ€™s Scientific Committee on Food recommended that a safe level of carrageenan in foods should not exceed 5%, and reiterated the prohibition of this ingredient in infant formulas2. However, in the U.S, even after recognizing the potential harms of carrageenan, the FDA still authorizes its use in processed food and infant formulas. The FDA affirms that the amount use in foods is relatively safe.3 Sources: 1. Prajapat VD, Maheriya MP, Jani KG, Solanki. KH. Carrageenan: A natural seaweed polysaccharide and its applications.
