It's like all the stuff with cigarette packaging here in Australia. First they put gross pictures on. Did that stop people smoking? Well, no... apparently not. Did it stop teens taking up smoking? Well, if the teens I see around me are evidence... then again, evidently not (even though they're not legally old enough to buy them). Now there's a new law (coming into practice at the end of the year, I think) that all cigarettes must be packaged in plain packaging (I'm assuming the gross pictures will remain). Will that change anything? Again, probably now (who cares if you don't have a pretty packet?!). People will choose to harm their health if that's what they want to do. Trying to ban stuff doesn't help. People need to make their own decisions for their own health.
I think it's also stupid to assume that sugary drinks are the leading cause of obesity... sure they're a contributing factor, but really they're not the be all and end all.
Ooooh and I should add THIS: http://www.time.com/time/world/artic...096185,00.html
"Other countries have imposed tariffs on food and drink considered unhealthy, but Denmark is taking the "fat tax" appellation literally. In the name of reducing cardiovascular disease, obesity, and diabetes, the law that went into effect on Saturday specifically targets saturated fats — the fats found most commonly in animal products like butter, cream, and meat. But few outside the government seem to think it's a good idea — or even a healthy one."
