The problem is that they don't know where to draw the line. They become believers in this business that everything is caused by diet and diet changes can cure everything etc. It's simply not true and gives level-headed health conscious people a bad name. They are extremists with their anti-doctor and medication comments. The reality is that not everyone will stay healthy and make it to 80. Follow the no-brainer advice but stop buying things from these people who are full of shit! They see their willingness to try anything as being open-minded when in fact they are suckers.
