> You talk about poison, but that is pure lie
I think it's fairly well accepted that the high obesity rates are caused by the shifting American diet. Yes it's more available than the 1950s (although I suspect not terribly so), but the effect it has on public health has been a nightmare.
Fundamentally, obesity is caused by an excess of calories. The foods we eat today are more calorie-dense. Even an apple is sweeter and larger than it was in the 1950s. But bottom line people are obese because calories are cheaper and more readily available than they used to be.
Shifting diet, but poison is the wrong term.
You can just as readily find correlation with behavioral changes linked to a sedentary lifestyle driven by a firehouse of entertainment that first became available with cable television. That doesn't satisfy the orthorexic cause, so isn't discussed much.
