Nutrition Degree

If you earn a degree in nutrition, or if you already graduated and now has a career associated with a degree in nutrition, the advantages of it? And also, what are your reasons for choosing a career in teaching or nutrition? I ask only because I am looking to take power in college. It is good to go on to higher education as a dietitian. See link below for more information. Be careful that the word "nutritionist" is taken by altmed idiot. Only "Registered dietitians" has no credibility.
