Yeah I think it has to do with the advanced medical care. Also, despite having processed foods, we simply dont have worry about not having food. Also I think the widespread availability of vitamin/mineral supplements and fortified foods goes a long way to help offset the processed food problem. I am not sure processing itself is a bad thing, it just has to be done in the right way. The processing involved in making extra virgin olive oil does no damage to the product, but when you start hydrogenating vegetable oils using high heat, solvents, and transition metals it becomes a problem.
