• Every year, food manufacturers pour 15 million pounds of artificial food dyes into U.S. foods. That amount only factors in eight different varieties, according to the Center for Science in the Public Interest (CSPI).
  • As of July 2010, most foods in the European Union that contain artificial food dyes come with warning labels, and the British government has also asked that food manufacturers remove most artificial colors from foods. In the United States, however, a similar measure has not been made.
  • According to a CSPI report, some of the most commonly used food dyes may be linked to numerous forms of cancer, along with hyperactivity and other behavioral problems in children.
  • Stick to whole fresh foods and avoid processed foods to steer clear of these artificial food dyes.


Food dyes are one of the most widely used and dangerous additives. While the European Union has recently placed regulations on labeling food dyes to inform consumers of the health risks, the United States has no such requirement.

Here are some of the most common food dyes used today, according to the Food Freedom Network:

  • Blue #1 (Brilliant Blue)

    An unpublished study suggested the possibility that Blue 1 caused kidney tumors in mice. What it's in: Baked goods, beverages, desert powders, candies, cereal, drugs, and other products.

  • Blue #2 (Indigo Carmine)

    Causes a statistically significant incidence of tumors, particularly brain gliomas, in male rats. What it's in: Colored beverages, candies, pet food, & other food and drugs.

  • Citrus Red #2

    It's toxic to rodents at modest levels and caused tumors of the urinary bladder and possibly other organs. What it's in: Skins of Florida oranges.

  • Red #40 (Allura Red)

    This is the most-widely used and consumed dye. It may accelerate the appearance of immune system tumors in mice.
