Yeah, that writeup actually has a few critical failures in logic in it. What do you expect though? It's a biased writeup from someone that doesn't mind playing fast and loose with facts to forward an agenda. Nothing new there though.
Example: High hip fracture rate, logic failure: Attributed to diet and not environment/ culture activities required.
After I saw the spelling of concrete though I wrote the whole thing off. The cool thing about the internet is that anyone can be an expert, and instantly get an audience.
