And share this powerful quote from the American Academy of Pediatrics (AAP):

The American Academy of Pediatrics has issued a statement in 2008 in response to the Lancet study:

“Although quite complicated, this was a carefully conducted study in which the investigators went to great lengths to eliminate bias and to rigorously measure outcomes. The results are hard to follow and somewhat inconsistent. For many of the assessments there were small but statistically significant differences of measured behaviors in children who consumed the food additives compared with those who did not. In each case increased hyperactive behaviors were associated with consuming the additives. For those comparisons in which no statistically significant differences were found, there was a trend for more hyperactive behaviors associated with the food additive drink in virtually every assessment. Thus, the overall findings of the study are clear and require that even we skeptics, who have long doubted parental claims of the effects of various foods on the behavior of their children, admit we might have been wrong.”

Please share this information with everyone.  And remember to vote with your dollars to influence what food is offered in the US – We have all the power to change our families’ food!
