Those studie are more than likely meant to decieve ! The study on beta carotine was definately brought to the public eye in this manpulated manner ! What is ommitted in these studies or what they dont tell, often is enought to camoflage the real outcome of them! In the beta carotine study what they dont tell you and is typicle of how the establishment decieves, is the important yet ommitted fact that those who actually did worse had also been previously diagnosed with asbestos poisoning!
With that in mind you can obviously concur that the rest of these studies have been falsified in one way or another!
You should alway look at who performed these studies and ask yourself ,what do they have to lose or gain by them!
The National Cancer Institution being one of the more notorious in th industry for there deceptive studies with the obvious goals of protecting there billion dollar industry!
