How are reactions to food additives diagnosed?
Today, scientists would demand stricter control of the process reported in 1959 to diagnose tartrazine as the cause of the hives. They question if other claims of adverse reactions to food additives are based on properly controlled studies showing a relationship. You may have reason to believe that you have adverse reactions to certain food additives. If you do, remove the additives from your diet for a few days. Your symptoms should promptly go away if the additive is the cause.
