(Celiac.com 04/10/2000) Spanish researchers, including Dr. Alicia Armentia Medina from the Hospital Rio Hortega in Valladolid, Spain, warn that people who have cereal allergies should exercise caution when drinking cola or cocoa products as these beverages may contain cereal proteins. These proteins could cause a severe asthmatic reaction in rare instances. Cereal allergies are very common throughout the world, and it is difficult to know the formulation of cola drinks. According to Dr. Medina: It is possible that they contain cereals. In their study, which was presented to the 16th World Congress of Asthma in Spain, Medinas team analyzed the allergic reactions of nine people who suffered severe asthmatic reactions after drinking cola. The researchers linked their allergic reactions to specific alpha-amylase inhibitor molecules that originate from wheat, rye and barley, and were found in their drink.
