Nutrition Classes

I want to go to college in health and nutrition. When I say diet and health care, I do not talk about health and nutrition. I'm talking about diet in the sense of how the right diet, and maybe take that advise people on how to take care of their bodies or just something that has to do with the type of work. This type of diet and health. I do not care. I was wondering if anyone could tell me in the right direction of classes and schools in this profession points. Thanks!
