If I were a psychiatrist, I would not be allowed to practice nutrition just as a dietitian could not practice psychiatry without the corresponding degrees. Dr. Barrett is not qualified to make professional judgments about the nutrition industry short of pointing out research. Even giving his personal view on research data is biased information, which amounts to nothing without a strong nutrition education. Couple that with the lack of dissenting research to his views (of which there are infinite examples), this site is misleading and quackery itself. It's like going to FoxNews for complete unbiased political news or MLB.com for news about all sports.
