I came across an interesting podcast on food dyes and their possible association with neurobehavioral conditions like ADHD. Here is an excerpt from the official podcast transcript.
AHEARN: Do you think the rise in ADHD diagnoses since the ’70s might be related to the increased number of artificially colored foods and drinks that kids are consuming?
WEISS: To me the evidence implicating food colors as a provocative chemical is clear. [But] you have to remember that these kids are exposed to thousands of chemicals in the environment. We know that some of them, such as lead, are very powerful members of the class of chemicals we call neurotoxicants; that is, they are toxic to the nervous system, to the brain. Endocrine disruptors such as those that are found in plastics also have the ability to change behaviors of this kind. Pesticides are also found in most children’s bodies today, and they too have the ability to provoke these kinds of behaviors. Our children are really facing an assault of chemicals, many of which have the ability to change how the brain functions.
Give my ADHD kid some Froot Loops and you will see a distinct different in his behavior. We used to follow the Feingold plan pretty strictly but have loosened up a bit (still no Froot Loops, though!). Perhaps we should revisit a stricter approach to it again.
