The assumption that the United States general population contains a majority of people who eat "wrong" is just that, an assumption.

I have read some studies that put the blame of shortened lifespan on stress...

There are very likely to be *many* factors involved.

Those who have an agenda will, of course, use whatever they can find to push the agenda forward.

Someone once said, "You are what you eat."

Someone else, perhaps much wiser, said, "All things in moderation."
