Here is a fun quiz from Nutrition Journal from a few months ago. It’s only 14 questions, so it won’t take long. You can pit yourself against medical students and practicing cardiologists, internists, and family practitioners. (Since the Nutrition Journal is open source, you can pull down the full quiz in pdf format if you like.)
Unless I miss my bet, most readers of this blog and certainly most readers of Protein Power and/or the Protein Power LifePlan will do better on this quiz than most of the above professionals.
