Nutritionists plan food and nutrition programs and supervise
the preparation and serving of meals.
Nutritionists help to prevent and treat illnesses by
promoting healthy eating habits and recommending dietary
modifications, such as the use of less salt for those with high
blood pressure or the reduction of fat and sugar intake for
those who are overweight.
Nutritionists manage food service systems for institutions
such as hospitals and schools, promote sound eating habits
through education, and conduct research.
