Why, exactly, does Allura Red AC (Red Dye #40) exacerbate attention deficit symptoms, or lower IQ?
What exact mechanism does this "artificial color" trigger in the brain that produces such pronounced symptoms in some people? Does it cause permanent, lasting damage, or is it a transient thing, like the effects from caffeine?

I don’t think the exact mechanism is known. Even the correlation is somewhat controversial still.
