Feingold Diet books at the library

I forgot to mention this.  There are books you can read, obviously, for free. One of the original books is 'Why your child is hyperactive,' by Ben Feingold.  I'm sure that hundreds of other books have been written.  Anyway, that book also contains some lists of particular foods, but I'm sure a lot has been added to those lists since then, especially because new foods have been 'invented' or 'discovered' over time.
