What Does a Nutritionist Do

A nutritionist is an expert in food science and human nutrition. Their main task is to assess the nutritional status of patients, develop personalized meal plans, and promote a healthy lifestyle based on scientific evidence.

The main duties of a nutritionist include:

  • Assessing individual energy and nutritional needs;

  • Analyzing eating habits and suggesting improvements;

  • Designing balanced diets for healthy individuals or those with specific needs;

  • Collaborating with doctors, dietitians, and psychologists in multidisciplinary teams;

  • Conducting nutrition education activities in schools, companies, or sports centers.

Contrary to popular belief, a nutritionist does not prescribe medication (unless they are also a medical doctor) but focuses instead on a preventive and behavioral approach to food.
