Thank you, thatbags, for that link.
For people who don't like links, here are a couple of quotes...
"Although the incidence of child obesity has fallen in the UK over the past few years, it is growing in low-income households."
"Shouldn’t a government that claims to care deeply about social justice be doing more to change this, to challenge businesses whose irresponsible practices tend to have a disproportionate impact on the poorest? True, the main front to act on is deprivation itself — the deprivation that drives such appetites. As George Orwell once suggested, “a millionaire may enjoy breakfasting off orange juice and Ryvita biscuits, but an unemployed man doesn’t . . . Unemployment is an endless misery that has got to be constantly palliated.”"
"And we must be honest that if you have less money — if you are less able to afford the consolations or the off-setting benefits of family days out, gym memberships, holidays — then you are inevitably more vulnerable to the temptations of cheap unhealthy food, cut-price booze or get-rich-quick gambling."
It's been mentioned somewhere on this thread that there's a strong correlation between obesity and deprivation, especially in certain areas. There was also a suggestion that poorer and unhappy people 'comfort eat'.
It should be blatantly obvious to politicians that there are an awful lot of people in the UK who feel 'out of control' (to borrow and adapt a famous slogan).
