I am thinking about something here...
Many parents will not allow their precious darlings to have sugar because it makes them "hyperactive".
To me, that means a bit of sugar is doing what nature intended it to do, and giving the kid some energy.
That is why, 35 or so years ago, kids set off to school after a nicely sugar laden bowl of cereal. They walked (yes!!!! walked!!!!) to school and were awake and alert at their desks..
By lunchtime the sugar had worn off a bit, they were getting tired.. so they had a lovely stodgy dinner in the school canteen, with an equally stodgy pudding.. and then ran around the playground until the bell went.
At the end of the school day, the kids piled into the sweet shop and raided the penny tray for shrimps, mice, and chocolate spanners.... and then (shock horror!) went out to play again... more running around.
So my theory is, nowadays, in this immobile generation that we have produced, who get a lift to school, nibble on a bit of mushroom hummous at lunchtime, then get picked up and go to play on their DS once they get home... their parents dont want them to have any sugar, just in case the little buggers actually want to move around.. (and if they happen to lapse and their offspring get some sugar down their neck and become a bit lively, we hear the cries of "oooh but he is hyperactive"...)
Thats all. :)
