David, I read the last stuff from Raisin Hell, and remembered the latest thing on our TV's from Eamonn Sullivan being used to promote the new CSR sugar, "with a touch of Stevia" as being good for you, etc etc.   I think you need to write another book, maybe in collaboration with an eminent Scientist, (eg) or some such person to get it through to these parents who just are being taken in by all the stuff put out by these companies, and marketed to children,  (sorry, pet hate is 'kids' a kid is a baby goat!).....
I feel very frustrated when I read about it, as I feel I can't do much, only try to spread the word myself when shopping.
A new book would get you on TV again, maybe when Mum's are watching, morning shows, or Dads, evening shows.
Since you've done it once, maybe it could be tweaked in such a way as to encourage parents to discuss it, maybe as a family thing, I don't know, only a suggestion. I'm floundering now, lol, so I'll stop now. sigh.

Keep up the good fight

Spread the Love
