Well, if that's what the medical data actually points to, while I don't think blame is really a useful concept, that would be the correct conclusion.

I don't know if that's actually the case, because I'm not a doctor, but I'll listen to them if they say it is.

Poor diet, alcohol abuse, and tobacco use can all certainly be attributed to corporate malfeasance in at least some part.

What did you read that made you think “This is blaming poor people!”?
