The independent report actually says that at places like the Subway chain, a cheap five-dollar offer on foot-longs has them flying out the door, and raising the unhealth index around the city. Actually, the City was cheating; while the independent study looked at what happened in poor neighborhoods, the city has been trying to look at what happens in the rich neighborhoods, mainly. Of course the neighborhoods with better access to healthier foods, would try those. There's hardly anything of intellectual worth in the City's report. The middle class, is going to be able to pay a premium on healthier low calorie food. The poor just tend to buy whatever comes in at under a dollar. And fast food calories tend to really add up in that price range.
But any way you look at it, New York certainly was the first city in the country to ask restaurants to post the energy content next to the prices of orders. Everyone else came after. Most states in the country still haven't caught up. The City tries to put a good face on it any way it can; for instance, they report that the fast food calories ordered at coffee shops are down 10%. How much the city can take credit for this is kind of up in the air, as customers at coffee shops pay no attention to calorie labeling. Only about one in ten customers actually even knows that they need to pay attention to this. However, one in ten isn't that bad. Food habits are about the hardest to change,and this does make for good start.
