Science and pseudoscience in adult nutrition research and practice

     The article is about how many nutritional claims are not proven scientifically. The speaker is Reynold Specter, a M.D. who also served as a professor of pharmacology, biochemistry, and medicine. He is writing this article because he views many "scientific" claims are false and possible harmful and he wants people to evaluate the credibility and accuracy of claims they see in order to be healthier. The article primarily relies on pathos in which he attacks the credibility of many nutritional claims and even states studies that show how excessive doses of certain vitamins are actually harmful to organisms. The article also used pathos because it does use words such as ludicrous, doomed, outrageous, etc. to create an emotional response against the lack of evidence in nutrition. The author does not refer to many of his own accomplishments in the field of medicine but he does make an appeal to ethos by aligning his beliefs in moderation with Aristotle, who is a respected philosopher( who ironically did not follow the scientific method at all). He often uses the rhetorical device of rhetorical questions by having his heading phrased as questions.
