what does red dye 40 cause

Red Dye 40 is a synthetic food dye made from petroleum and is approved by the U.S. Food and Drug Administration (FDA) for use in foods and drinks. However, some studies have linked artificial food dyes like Red Dye 40 to hyperactivity, including ADHD, allergies, immune disorders, mind-storms, and even inflammatory bowel diseases. Red Dye 40 contains benzene, a known cancer-causing substance, and has been found to be contaminated with benzidine or other carcinogens. Red 3, another food dye, causes cancer in animals, and there is evidence that several other dyes also are carcinogenic. At least four dyes, including Red Dye 40, cause hypersensitivity reactions. Some people are allergic to certain synthetic dyes, and in these cases, coming into contact with Red Dye 40 may cause an allergic reaction. Although the consensus from health organizations is that Red Dye 40 poses little health risk, the dye has been implicated in allergies and worsened behavior in children with ADHD. It is recommended to read labels to avoid food dyes and find healthy alternatives.
