The only way you can stop people from eating junk food is to stop selling it full stop. I'm as guilty as anyone, cooking and tidying up afterwards seems like an awful lot of effort for just me. I like vegetables, but i can't work up the enthusiasm to prepare or cook them. I work full time and i'm tired when i get home from work, it's much much easier for me to pick up a ready meal on the way home rather than cook food from scratch. I'm not alone, i bet there's lots of people out there who have the same routine. (I'd like to point out that i haven't been near McDonalds in months...i've missed my chip ration this week due to illness too, i'm also off chocolate bars thanks to this annoying problem i have with regulating my blood sugar...grrrr.) I'm not likely to change my habits drastically unless all the ready meals suddenly disappear off the shelves, or i win the lottery (which i'll have to enter first) and employ a chef/personal trainer.
But Northy's right (oh, how may times have i written that? 🙂) there isn't enough, free, accessible support for people who would like to have a healthier lifestyle. Weightwatchers and slimming world cost money, as doe gym memberships, as well as requiring the right kind of motivation, they're not for everyone. The supermarkets all have diet clubs/schemes too, but they take time and money and organisation to follow, as well as will power. Busy parents might not have the time for this when they've got kids to look after.
Even if you are cookery loving foodie it's not much better. Weirdly i quite like watching cookery shows on tv (after all, i don't have to do any work in preparation, clean up afterwards and i don't even have to eat the stuff!) and we've got a constant supply of cookbooks sold at work. It's all made with the best possible quality fat, sugar and god knows what else. Yes, Nigella, i'm talking to you, you're terribly glamourous and i admire your enthusiasm but you never cook with Splenda! Does Jamie Oliver ever break out a jar of Canderel? Does Gordon Ramsey ever use low fat spread when he could use butter? Ever seen semi-skimmed or skimmed milk on Delia Smith? I don't think so.
But if you ban junk food you're curtailing people's rights to eat what they like, and putting a heck of a lot of people out of jobs.
I think the best solution would be for somebody to create a chain of fast food take-aways which served healthy, fresh food. I don't care who, maybe Jamie Oliver's up for a challenge?
Incidentally i did "Home Economics" at school, as did the boys, but the healthiest thing i remember cooking was goulash.
