A dietary aide, also called a dietary or dietician assistant, makes sure a person is provided with the necessary nutrition to restore or maintain health and well-being. He assists dietitians in planning and executing programs highlighting necessary vitamins and nutritional elements. These programs may be prescribed by a physician for a patient who has undergone medical or surgical procedures and requires dietary restrictions. The plan may also be established for people interested in promoting healthier eating habits for better living and increased longevity.
