In the UK a Nutritionist will be registered with the Association of Nutrition which is a voluntary register of competent, qualified nutrition professionals who meet the rigorously applied standards for scientifically sound evidence-based nutrition and its use in practice.
All Registrants have a minimum of degree-level nutrition science and have committed to adhere to the Association for Nutrition Standards of Ethics, Conduct and Performance. They will also have to demonstrate that they are continuing their education to keep up with the latest research in science. They will also have insurance.
If you are looking for a qualified nutritionist, always check they have the quality mark post-nominal letters RNutr or ANutr after their name.
