We also know that the vast majority of the "experts" who write these articles are those in the health and weight loss industry, such as nutritionists, health program supervisors, weight loss counselors, and lay people with an extreme interest in health and fitness. While I am certainly not suggesting that anyone is fabricating evidence or creating thought processes that are not accurate, I am however, indicating that when a person is educated to see things in one specific manner, it can be very difficult for them to see the same principles in a varying manner.

For example, if a dietician goes to college and is taught that green beans cause cancer, that dietician will graduate believing that green beans cause cancer. If the same dietician returns for occasional classes to keep her education current, and over the course of the next ten years, the dietician is once again taught that green beans cause cancer, then the dietician will continue to believe this and teach her clients this as well. Fifteen years later someone comes along and points out to the dietician that green beans don't cause cancer, how likely is the dietician to believe that green beans don't cause cancer?

This phenomenon is not solely related to dieticians and health related fields. This phenomenon actual relates to every field. As a writer I was taught that you never speak in double negatives. It's a basic principle I apply every day. If someone tried to convince me that the rules had suddenly changed, right or wrong, it has already been ingrained in me that double negatives are inappropriate and you shouldn't use them. Thus, if I criticize this new theory without completely re-educating myself on the basic rules of English and grammar, then I am relying solely on my previous knowledge to dispute this issue.
