Red Algae and the Dairy Free Diet

Red algae, also known as red seaweed, encompasses a variety of edible seaweeds such as nori, dulse, and Irish moss. These seaweeds are rich in nutrients and are particularly noted for containing carrageenan, a polysaccharide used as a thickener and stabilizer in food products. Red algae are harvested worldwide and are integral to many traditional dishes, especially in Asian cuisines.
