I think it is daft, they peddle all sorts of cheap sugar laden 'healthy breakfast cereals' and mountains of carby, fatty junk food, but ribena is the big bad guy responsible for obesity? ludicrous!

I have 3 DC aged 10,13,15, none of whom have any fillings at all and all who drink squash etc in moderation - water being the preferred choice at all meal times,they each get a carton of juice or smoothie in their lunch box but fizzy drinks and posh drinks like shloer, J2O are only for special occasions.
