If the nutrition course was based on biochemistry and physiology, then it absolutely counts towards your BCPM. AMCAS provides GUIDELINES, but they say clearly that course classification is NOT based on the department, it is based on COURSE CONTENT. If the words "biochemistry" or "physiology" are anywhere in the title, you are not going to have a problem. I think AMCAS is only going to give you a hard time when it is CLEAR that the course is classified wrong. I took a class that sounds similar and checked before taking it that it would count towards BCPM. In fact, it is an advanced biochemistry course...just because it is offered through the Nutritional Science department does preclude it from being categorized as a BCPM course.
