A dietitian teaches people how to be more healthy. This is by looking at their diet and getting them to eat healthy foods.
Seeing a dietitian can stop people from having problems caused by poor nutrition.
Dietitians treat diseases like obesity. They also work with people who have had to change their diet because of illness. This could be diabetes or kidney disease.
They often work in hospitals but sometimes you’ll find them in other places. These might be in areas where food is made or sport is played. Some dietitians even work at the zoo!
