The skepticism over alternative (or natural) health is what primarily got my attention. Lately, I've gotten a bit fed up with so many on the leftwing sites exposing their lackadaisel knowledge in the area of health (alternet had an ill-thought out article on vitamins being a scam). Most people do not take nutritional medicine seriously. In my own life I've observed that they either ignore you, laugh at you, or listen in simple bemusement if you try to talk about potential nutritional cures though the field of orthomolecular medicine has been around even before modern medicine. And many scientists work in the field of nutrition (but the alternet article didn't care to interview any of them unfortunately).
Now the criticism of industrial agriculture is right on and all the more contributes to the necessity of nutritional medicine. As for the whole elitist thing that supposedly pits low-income food buyers against high-income food buyers: hey, thats only a further sign that theres something truly fucked-up about our food system and society as a whole. Your not suppose to want junkfood. Fast food should not exist. Massive confined lots of animals is a blight on the otherwise green Earth. Change your mindset.
Of course, the emotionally-illiterate, left-brainers the world over have to pick out and construct a rational side to every and any thing. While thats not entirely bad in itself still you must remember the baggage that comes with certain topics (parapsychology being amongst them). To add another thing, Grist like most of the environmental movement espouses vegetarianism. Anyone brought up on the idea of vegetarian diet being "healthy" could possibly face some real confusion as it pertains to nutritional information. Its not a healthy diet at all. Sorry, vegans! Truth hurts and worst than being told that artificial vitamins are useless.
