A sales tax is a poor solution though. You can eat unhealthy food, as long as you don't eat too much.1) Fat people do not necessarily die earlier. Being fat is not a quick death sentence, it only makes it more likely.
2) Currently, only one US state has an obesity rate under 20%. In other words, over one in five americans is obese. That is a drain on health care. IE- Diabetes.
You don't fix skyrocketing health care costs without making people have to be more personally accountable, and if you have do do that on the point of a sales tax, I'm all for it.
It would be like taxing bathing suits to pay for the costs of skin cancer.
