For urban it’s over a mile away, for rural it’s 10miles away. There are some other factors that go into it as well but that’s the distance you were looking for. I think around 20 million people are considered to be in a food desert so certainly it doesn’t explain the obesity epidemic.I need some information to determine what classifies as a "food desert." As in something quantifiable.
How many blocks does a person need to travel to get to a place with reasonable food, or to a bus stop that will get them close to one?
You are also correct on the big gulp analogy, however from talking with thousands of patients many people have no idea just how bad it is until it’s a problem. The way people cook also is something that many don’t have an understanding of. Their are societal and cultural issues as well in many cases. The food/reward cycle is hard to break.
