A nutrition counselor educates patients about food nutrition and how it affects quality of life and health care issues. In this career, your duties include meeting with clients, assessing their current nutritional habits and comprehension, and helping them to understand how healthy eating and diet play roles in their overall health. In some cases, you may simply provide more information for your clients, while other times a nutritionist works with the patient to develop health and nutrient goals and a new meal plan that contributes to the patients reaching their goals.
