Though my line of work is not nutrition or nutrology, most of that info is hogwash. No, I'm not going to prove you why it's hogwash; it took me 6 years in med school plus 3 years in a residency program plus I don't know how many hundreds of hours reading medical journals to be able to say with conviction that most of that info is hogwash. It would take a LOT of time to hunt down over the web all the info and data I would need to make a case on what I'm saying. But by no means you should take my word for it, so if you want proof, talk to a doctor or nutritionist you trust and I'm positive they can give you a lot of info - it's way easier to explain all this talking instead of writing. Typing all that is needed here would be a huge chore and a big drag for everyone - specially me .
Simply because you can't prove it.

And maybe just a little common sense.
1,000's of grazing animals forced together in a feed lot and fed corn vs grazing animals allowed to actually graze on pasture.
Which is a healthier system?
Remember...these are "grazing" animals, and have been for 1,000's of years.
Healthy animals produce healthy meat.
I stand by common sense
