What Is Carrageenan and Why Is It in Your Oat Milk
This seaweed-derived thickener is in hundreds of products and has been controversial for decades.
A natural ingredient with unnatural effects
Carrageenan is extracted from red seaweed and used as a thickener in dairy alternatives, deli meats, infant formula, and protein shakes. Researchers have studied it for decades because of its ability to trigger inflammatory responses in the gut.
The ongoing debate
The FDA considers carrageenan safe. The EU has banned it from infant formula. The concern is chronic low-level inflammation from daily exposure across multiple products. If you drink plant milk, eat deli meat, and have a protein shake, you could be consuming carrageenan three or more times per day.
