Nutritionists are mainly concerned with wellness and prevention of illness through healthy diet and nutrition. They also evaluate and help treat some medical disorders (obesity, hypertension, diabetes) by suggesting modifications of the patient's consumption of certain food items. Some food manufacturers, advertisers and marketers hire hutritionists to analyze, test and develop meals. Nutritionists also may work in schools, hospitals, clinics, nursing homes and prisons..
Community nutritionists sometimes advise people and groups on nutrition and health. They may recommend diet plans for families, including guides to preparation and shopping. Nutritionists may study dietitics, food and nutrition, or food service systems management, with courses in biology, microbiology, psychology, sociology, statistics and mathemetics.
