It is surprising to me that the author, with all of her education and background never learned to write an objective piece. She also included resources such as Quackwatch which is a nonprofit which is owned by a person in the medical field which represents a conflict of interest. She should pull information which more adequately represents both sides of the coin; i.e., pull more data which includes some independent sources.

I thought it was very interesting, especially breaking down the types of quackery. I was made more aware of the danger of the supplements and vitamins, which are poorly regulated.
