"These synthetic chemicals do absolutely nothing to improve the nutritional quality or safety of foods, but trigger behavior problems in children and, possibly, cancer in anybody,” said CSPI executive director Michael F. Jacobson, co-author of the 58-page report, “Food Dyes: A Rainbow of Risks.” “The Food and Drug Administration should ban dyes, which would force industry to color foods with real food ingredients, not toxic petrochemicals.”
"Blue 1, Red 40, Yellow 5, and Yellow 6 have long been known to cause allergic reactions in some people. CSPI says that while those reactions are not common, they can be serious and provide reason enough to ban those dyes. Furthermore, numerous studies have demonstrated that dyes cause hyperactivity in children."
“Dyes add no benefits whatsoever to foods, other than making them more ‘eye-catching’ to increase sales,” said James Huff, the associate director for chemical carcinogenesis at the National Institute of Environmental Health Sciences’ National Toxicology Program. “CSPI’s scientifically detailed report on possible health effects of food dyes raises many questions about their safety. Some dyes have caused cancers in animals, contain cancer-causing contaminants, or have been inadequately tested for cancer or other problems. Their continued use presents unnecessary risks to humans, especially young children. It’s disappointing that the FDA has not addressed the toxic threat posed by food dyes.”
"Fortunately, says CSPI, many natural colorings are available to replace dyes. Beet juice, beta-carotene, blueberry juice concentrate, carrot juice, grape skin extract, paprika, purple sweet potato or corn, red cabbage, and turmeric are some of the substances that provide a vivid spectrum of colors. However, CSPI warns that “natural” does not always mean safe. Carmine and cochineal—colorings obtained from a bright red insect—can cause rare, but severe, anaphylactic reactions. Annatto, too, can cause allergic reactions."
