>Obesity is a particularly tough one, though. Generally, populations that eat less (and less unhealthy simple-carb-based-stuff) and walk more appear to have less obesity, but politically this isn't a big winner. The reason people are obese also has to do with many other factors. Fat food is very, very cheap in the US, especially compared to normal food and greens. one solution to this is to tax fat food and use this tax to lower the tax on healthier foods, thus subsidizing healthy behaviour. This makes healhy food available for the poor strata.
