Thank you for your thoughtful comments.

I'm not trying to cover all aspects of obesity in the US. Just one angle. The angle of healthy food being more expensive than cheap food, and the reason for that. That is all. Nothing more.

Anyone, regardless of socioeconomic status, can have emotional problems that lead to unhealthy eating. Rich people also have eating disorders. But they have access to gyms and good doctors, too.

The point is that we often blame poor people for eating crappy food, when in fact, it's simply cheaper to eat really awful food. In a way, they are making an efficient and frugal choice, albeit with terrible consequences.

I don't think that emotional eating alone can explain the obesity epidemic that we face. So much more factors in: our sedentary lifestyles, our instant-gratification culture, the sheer size of our country (which makes is easier to drive around than to walk or ride a bike). The issue is too big to grapple with in a blog. I'm merely touching on one little section.
