Anecdotal evidence is not as reliable as scientific evidence. It's too subjective -- usually coming from parents' observations. But the quantity of anecdotes against artificial food coloring is growing too large to ignore. Below are a few on the Internet. For more stories, click the source links.
On a side note: Some people are allergic to food colors, and some people are sensitive to them. As Jane Hersey, author of Why Can't My Child Behave?, explains "What we deal with in most people is not an allergic response but a sensitivity," says Hersey. "If your family moved to a city that was very polluted, different family members would react differently. One might have an asthmatic attack. Another would get a headache, but you wouldn't say you're allergic to pollution."
Please remember that not all aggressive or hyperactive behaviors can be eliminated by removing artificial food colors and preservatives from the diet. However, these parents show that it can help many children.
