Sorry, it's not a site that's backed well. One peer-reviewed study is quoted (and the link doesn't even work so without looking for it, I can't even say what's true....and it's a partial quote at best). In addition, there are many partial quotes from sites that simply publish opinion and not fact. Many of the "source" links do not work. All in all it's hard to take any of it seriously simply because it's poorly researched with little credible support. Hell, they even quote a thread (that's a bad sign).
