Have you experienced flushing or hives after eating certain processed foods? Then may be allergic to food coloring. Other mild symptoms of a food coloring allergy include headaches and itchy skin. More severe allergic reactions are facial swelling, tightness in chest, difficulty breathing, and anaphylaxis. The major food dyes responsible for food coloring allergies are tartrazine (FD&C yellow #5), carmine (red #4), and annatto. Tartrazine is a synthetic food coloring used to imitate the color yellow. It causes the most allergic reactions of all the food coloring. Carmine gives food products their red color. It is the main dye found in red meat. Annatto gives food products their yellow or orange color. It is a natural food dye and not listed as a separate ingredient, but can still cause severe allergic reactions. It is difficult to diagnose a food coloring allergy, but an allergist can conduct provocation or elimination tests. Provocation allergy testing is exposing an individual to an allergen in a clinical setting to see if it evokes an allergic reaction. In contrast, elimination allergy testing is removing certain foods from an individual’s diet to see if allergy symptoms subside. While the best course of action is to visit an allergist, you should also avoid certain foods if you believe you have a food coloring allergy.
