In Brazil, we have a law: who has not a nutrition degree, after 4 or 5 years in university, can not prescribe a diet. That┬┤s because nutrition envolves a lot of nuances, begining by biochemistry (in all situations!) and the knowledge about physiology in each time of life and in all the patholgical situations, in which we must use nutrition for controlling diseases or disfunctions. I believe that in USA must be the same. Usually, I work together with Exercise┬┤s and Sport┬┤s Professsionals. It┬┤s better for the clients and for us, of course.
