I am a nutritionist in Mexico and I have a bachelor's degree.(I studied for four years at a university) In mexico my bussiness card says L.N. which means licenciada en Nutricion. I don't know how to translate that.
There are several ways this can be translated. Some of which I have seen are:
- Licensed Dietitian
- Licensed Nutritionist
- Has a BSc in Nutrition
To my knowledge, there is no legal requirement in the United States that one of these be chosen over the others and in my personal opinion either of the first two are sufficient. In the United Kingdom though, a Dietitian is someone who advises someone on their personal diet and diagnoses issues related to malnutrition while a Nutritionist gives general advice on how to eat.
