Quick Answer: Carrageenan is approved by the FDA as a food additive, but research has raised concerns. Studies show degraded carrageenan (poligeenan) causes intestinal inflammation in animals. The EU banned carrageenan in infant formula in 2018. Many brands have voluntarily removed it.
Carrageenan is a thickener and emulsifier extracted from red seaweed. It's found in almond milk, ice cream, yogurt, deli meats, and infant formula. While food-grade carrageenan is considered safe by the FDA, concerns center on the fact that it can degrade into poligeenan during digestion or processing — and poligeenan is a known inflammatory agent used to induce intestinal inflammation in lab studies. The National Organic Standards Board voted to remove carrageenan from the list of approved organic ingredients in 2016. The EU specifically banned its use in infant formula. Many major brands (Silk, So Delicious, Stonyfield) have voluntarily reformulated to remove carrageenan.
