No, it's not a difficult special—you just have a lot of science courses you need to take, such as microbiology, biochemistry, biology, and chemistry—before you start taking higher-level nutrition courses. Nutrition and Dietetics is an incredibly difficult, science-based title. Specializing in nutrition isn't as difficult as most. Some of the science classes are difficult, but many of the upper division nutrition classes are easier because the concepts are applicable to daily life.
I'm starting college studying nutrition (taking basic classes) but I don't like chemistry or laboratories, but I chose the specialty because nutrition is very interesting. If a nutrition student asked me for an interview or someone at a cocktail party asked me a question about nutrition, I would use it as an opportunity to practice my media skills. In addition, the food industry, nutrition consulting groups, industrial bodies and nutrition companies are also feasible. If you're thinking about studying nutrition or starting a career in nutrition, get ready to run a business.
