Within one minute of eating a piece a cake, my son is hyper. This “sugar high” is expected, but what isn’t expected is an instant high from processed foods containing additives or food colorings. Foods with additives trigger hyperactivity in additive-sensitive children. It makes me wonder if changing my son’s diet may make a difference. Will this information change your shopping habits? Lots of foods for children have long shelf-lives—making the effort to avoid additives a tricky endeavor. What are your thoughts?
