Ingredient Information

Function

Red 40 is one of two red food dyes that are considered safe by the Food and Drug Administration (FDA). Food colorings are used to complement the natural color of foods; create fun foods, such as children’s foods; or offset color loss that results from exposure to light, air, temperature, or moisture. Red 40 is common in soda, candy, gelatin desserts, pastries, cherries and sausage.

Other Use and Industries

Red 40 is commonly used in drugs, cosmetics and pet foods.

Health Effects

The most common negative health effect resulting from Red 40 consumption is allergic reaction. There has been evidence implicating Red 40 in causing cancer in test rats, however, such evidence has been deemed inconclusive and non-substantial. Other results, like lower reproductive success, weight, and survival of offspring, as well as behavioral changes in animals, have also been determined inconclusive.

There has been public debate surrounding food dyes since the 1970s. There has always been a theoretical link between food coloring and the rise of Attention Deficit Hyperactivity Disorder (ADHD) in children. The link has not been proven, however, many parents who have eliminated foods with artificial coloring claim that the results have been positive. Many of the foods that contain food coloring are "junk foods," foods that have calories yet little to no vitamins or minerals. Eliminating these foods would very likely have the positive effect of also increasing a child's intake of vitamins and minerals.

Despite federal and industry claims that Red 40 is safe, it is recommended that pregnant women in particular limit their intake of this food additive. Red 40 can also cause allergies in some individuals, though is not related to other food allergies.

Origins

Red 40 is made from petroleum and is artificially synthesized in a laboratory.
