Food dyes are best known for triggering behavior problems in sensitive children, but they have the potential to cause many other problems as well.
Depending on where one is most sensitive, dyes can impact any organ of the body. Humans were not designed to consume petro-chemicals.
“Artificial food color usually contains petroleum and is manufactured in a chemical process that includes formaldehyde, aniline, hydroxides, and sulfuric acids...Sometimes lead, arsenic, and mercury may be present as impurities.”

Many people now understand the connection between fake dyes and ADHD, but both research and practical experience has shown that it is likely a child with symptoms of ADHD will also suffer from additional problems. Such problems may include asthma, chronic ear infections, leg aches, migraines, sensory deficits, bedwetting, mood swings gastrointestinal problems, vision problems or tics, night terrors, excessive fearfulness, obsessive behaviors, eczema, among others. Some children have several of these issues.
The first dye to be linked to serious health problems was tartrazine (Yellow No. 5). Allergists were reporting that some of their patients were experiencing asthma or hives as a result of consuming the dye; many of these people were also unable to tolerate aspirin.
