Because learning about nutrition is a topic that anyone can benefit from, you don't really need any special experience or skills to learn about it. However, if you're working towards a career in the field of nutrition or looking to advance your career, you may find that previous experience or classes in biology, psychology, anatomy, agriculture microbiology, biochemistry, or public health can be helpful. Previous work as a nurse, nursing assistant, fitness trainer, counselor, or other role that may involve teaching patients to eat a healthy diet can also help prepare you to study nutrition.
