Do not believe anything from this site. They are largely not MDs but rather a vegetarian action group. There have been radio talk show "debates" over them in the DC area maybe 2 years ago.

For studies use MEDLINE the search engine for peer reviewed Medical studies. pcrm is more misinformation than anything good.

They are far more than a vegetarian action group. They're nothing more than a front for animal rights activism and have been tied financially to groups such as ALF, SHAQ and ELF as well as sharing executive staff with PETA. IMO, there is nothing 'balanced' about their views whatsoever and no more than 5% of their membership are actually doctors.
