There is a lot of overlap between the roles of nutritionists and dieticians, but there are some key distinctions. A dietician is a professional who is qualified to create meal plans and provide nutrition counselling to individuals and groups. They may also work in the food industry, developing and testing recipes. A nutritionist is typically someone who has studied nutrition and has a deep understanding of the role that food and nutrition play in health and wellbeing. They may provide advice on diet and nutrition, as well as on supplements and other forms of treatment. Some nutritionists also work as dieticians.
