Bottom Line: Artificial food dyes are petroleum-derived substances that give color to food. Artificial Dyes Currently Used in Food.

Red No. Yellow No. Blue No. Bottom Line: Studies suggest there is a small but significant association between artificial food dyes and hyperactivity in children. Do Food Dyes Cause Cancer? The safety of artificial food dyes is highly controversial. However, the studies that have evaluated the safety of food dyes are long-term animal studies. Nevertheless, other dyes may be more concerning. Concerns About Blue 2 and Red 3 An animal study on Blue 2 found a statistically significant increase in brain tumors in the high-dose group compared to the control groups, but the researchers concluded there was not enough evidence to determine whether Blue 2 caused the tumors Some Dyes May Contain Cancer-Causing Contaminants While most food dyes did not cause any adverse effects in toxicity studies, there is some concern about possible contaminants in the dyes More Research is Needed Artificial food dye consumption is on the rise, especially among children.

Bottom Line: With the exception of Red 3, there is currently no conclusive evidence that artificial food dyes cause cancer. Do Food Dyes Cause Allergies? Bottom Line: Some artificial food dyes, particularly Blue 1, Red 40, Yellow 5 and Yellow 6, may cause allergic reactions in sensitive individuals. Should You Avoid Food Dyes? The most concerning claim about artificial food dyes is that they cause cancer.

It's safe to eat, but do you really want to be eating bugs? In some ways it's better to go artificial with food coloring, but not just to avoid eating bugs. One big reason to go artificial is because it is more cost-effective. Synthetic dyes can be mass-produced at a fraction of the cost of gathering and processing the organic material used to make natural colorings.

Artificial dyes often last longer than natural colors, so they can stay on your shelf for years. Plus there is no limit to the variety of colors that can be artificially produced in a lab. There is some controversy, though, behind artificial food coloring, as their use has been linked to obesity, cancer, and hyperactivity. However, many artificial dyes are FDA-approved and are completely safe to eat.

Lakes for food use must be made from certified batches of straight colors. One exception is carmine, which is a lake made from cochineal extract. Lakes for food use are made with aluminum cation as the precipitant and aluminum hydroxide as the substratum. Mixtures are color additives formed by mixing one color additive with one or more other color additives or non-colored diluents, without a chemical reaction for example, food inks used to mark confectionery.

In addition, any chemical that reacts with another substance and causes formation of a color may be a color additive. For example, dihydroxyacetone DHA , when applied to the skin, reacts with the protein of the skin to impart color. Even though DHA is colorless, it acts as a color additive when used for this purpose and is regulated as a color additive. There is no "generally recognized as safe" GRAS exemption to the definition of a color additive. Naturally occurring color additives from vegetable and mineral sources were used to color foods, drugs, and cosmetics in ancient times.

Paprika, turmeric, saffron, iron and lead oxides, and copper sulfate are some examples. The early Egyptians used artificial colors in cosmetics and hair dyes. Wine was artificially colored beginning in at least BC. In , William Henry Perkin discovered the first synthetic organic dye, called mauve. Discoveries of similar dyes soon followed and they quickly became used to color foods, drugs, and cosmetics.

Because these dyes were first produced from by-products of coal processing, they were known as "coal-tar colors. Federal oversight of color additives began in thes. The assessment of color-imparting ingredients in foods was among the first public initiatives undertaken by the U. Butter and cheese were the first foods for which the federal government authorized the use of artificial coloring. By , many foods, drugs, and cosmetics available in the U. However, not all of the coloring agents were harmless and some were being used to hide inferior or defective foods.

A careful assessment of the chemicals used for coloring foods at the time found many blatantly poisonous materials such as lead, arsenic, and mercury being added. In many cases, the toxicities of the starting materials for synthesizing coloring agents were well known and could be toxins, irritants, sensitizers, or carcinogens.

Food and Drugs Act. In , Congress passed the Food and Drugs Act, which prohibited the use of poisonous or deleterious colors in confectionery and the coloring or staining of food to conceal damage or inferiority.

The USDA had initial enforcement authority for this act. Subsequent F. The agency was first called the Food, Drug, and Insecticide Administration and was given its current name in Federal Food, Drug, and Cosmetic Act of In the s and s, it became clear that the Food and Drugs Act of did not go far enough to protect the public health from misbranded, adulterated, and even toxic products, including an eyelash dye that blinded some women.

The Federal Food, Drug, and Cosmetic Act of further increased government oversight of food and drugs and, for the first time, passed legislation for the regulation of cosmetics and medical devices.

In addition, the act: contained adulteration and misbranding provisions for the use of coal-tar colors in foods, drugs, and cosmetics; required the listing of new colors; and made mandatory the previously voluntary certification program for batches of listed colors, with associated fees.

The initial listing of lakes for food use under the act restricted their use to coloring shell eggs egg dyeing.

FDA also established labeling and recordkeeping provisions, identified diluents that could be added to color additives, and established procedures for requesting certification of color additives and adding new color additives to the permitted list. Color Additive Amendments of That same year, U.

House Representative James Delaney began holding hearings on the possible carcinogenicity of pesticide residues and food additives. Orange B is used only for hot dog and sausage casings. Citrus Red 2 is used only to color orange peels.
