Yeah… seeing stuff like this only confirms my mounting suspicions over the years. We are being massively sold out by our food system. It has gotten worse every decade due to

a) increasing centralization, so produce has to be picked earlier and transported farther
b) increasing use of pesticides and fertilizers tailored to make produce big and pretty, but not nutritious
c) genetic modification, all aimed at making food easier to transport, more impervious to pesticides and pests, and of course prettier, but who cares about nutrition?
d) A huge industry dedicated to convincing people that their nutritional requirements can be met in pill form. We know that most vitamins cannot really be used by the body sans their natural environment. A vitamin is not just a substance, but a biological mechanism. Just extracting a substance from that mechanism does not provide the same benefit.
e) An even huger industry selling "replacement foods". If it is processed and in a box, what's the likelihood that it has anywhere near the vitamin capability of the produce it was derived from?

The way I see it, the only supermarket food that has any redeeming quality might be the frozen vegetable section. At least some companies work hard to freeze the produce within hours of picking, to lock in the nutrition. I'm sure the act of freezing probably reduces the vitamin efficacy somewhat, though.
