A nutritionist helps people with special dietary needs, such as food allergies, or who want to decrease their weight. Nutritionists can be trained, have a degree, and in some states, be licensed. In other states, anyone can use the title “nutritionist” and not be trained or licensed.

Licensing has been under discussion by nutritionists for some time. The American College of Nutrition, the association for nutritionists, had developed the Certification Board of Nutrition Specialists, or CBNS. As of 2010, the CBNS became an entity of its own. CBNS has rigorous qualifications for those wishing to be certified. Only 24 of the 50 states require nutritionists to be licensed, according to the Commission on Dietetic Registration.
Traditional training programs usually take the form of attending college, taking courses, doing an internship, and often getting a master’s degree or even a Ph.D. Online programs in nutrition are also available with the same requirements. You may want a different approach to nutritional training, particularly if your state does not require licensing. You may want additional training in different aspects of nutrition you didn’t have time for in the past. Or you may not have the money to spend on a more traditional approach. There are a wide variety of options, and they’re all free.
Basic nutrition courses from reputable schools are available for free. Johns Hopkins offers Principals of Human Nutrition.
