As the medical model gradually shifts toward the bio-psycho-social medical model, the role of nutrition in disease prevention, treatment, rehabilitation, and health care has become increasingly prominent. The saying "three parts treatment, seven parts nourishment" highlights that scientific, timely, and rational nutrition not only aids clinical treatment but is also key to "preventing disease before it occurs" and "treating pre-disease." Clinical nutrition is an important subspecialty within hospital clinical disciplines. It aims to enhance immune function and improve disease outcomes by controlling the intake of three major nutrients, as well as minerals and vitamins, thereby shortening hospital stays and promoting early recovery. Our hospital currently has five dietitians, including one senior dietitian, three supervising dietitians, one master's degree holder, and three with national registered dietitian qualifications. They are responsible for nutritional screening, assessment, consultation, and education for inpatients, providing nutritional support for various lung diseases such as tuberculosis, tumors, pulmonary hypertension, and perioperative pulmonary conditions, as well as nutritional guidance and intervention for metabolic and chronic diseases including diabetes, gout, chronic kidney disease, and cardiovascular diseases. They also develop individualized dietary plans for critically ill patients and operate specialized nutrition clinics to offer nutritional guidance and consultation for various patient groups. In 2020, 95,006 nutritional screenings, 814 nutritional assessments, 3,253 nutritional education sessions, 37 nutrition clinic visits, 30,885 therapeutic diet orders, 997 oral nutritional supplementations, 2,753 enteral nutrition interventions, and 8,662 accelerated rehabilitation nutritional support cases through MDT participation were conducted. Currently, the Nutrition Department of Shanghai Pulmonary Hospital is equipped with advanced instruments such as body composition analyzers, handgrip dynamometers, and skinfold calipers, enabling precise nutritional assessments and the provision of relevant nutritional treatment plans and recommendations. Additionally, the department has launched online nutritional education via the WeChat platform, allowing real-time interaction with patients and timely responses to their inquiries. The Nutrition Department has completed one hospital-level research project and participated in one Shanghai Science and Technology Commission project. It has published one SCI paper and over ten papers in core journals, delivered one conference presentation, and participated in multiple poster exchanges. The department has also been involved in television health promotion programs such as "Health Lecture Hall," "Live to 100," and "Famous Doctors' Consultation." For several consecutive years, the Nutrition Department has ranked among the top third in the specialized hospital assessments conducted by the Shanghai Clinical Nutrition Quality Control Center. It has received the China Medical Promotion Association's Smart Hospital Project: Huatuo Engineering Public Welfare Initiative—Innovation Unit for Hospital Smart Nutrition Education and Service Development. In 2021, it was awarded the China Rehabilitation Medicine Association's Popular Science Advanced Individual Award. In terms of academic appointments, the department has one standing committee member of the Nutrition Academic Department of the Tuberculosis Prevention Branch of the China Medical Promotion Association, one deputy secretary-general of the Nutrition Branch of the Chinese Antituberculosis Association, and one secretary of the Nutrition Academic Department of the Tuberculosis Prevention Branch of the China Medical Promotion Association. The department also undertakes teaching responsibilities for advanced trainees and interns. In party building efforts, the department has one outstanding Communist Party member from Shanghai Pulmonary Hospital and received the "United with the Party, Unchanged Medical Heart—Excellent Interview and Essay Award for My Experience of Shanghai's Health Stories in the Centenary of the Party." The Nutrition Department is dedicated to serving all patients, striving to be advocates of healthy living, and actively responding to and implementing the policies of the "Healthy China Initiative (2019–2030)" and the "National Nutrition Plan (2017–2030)." Healthy China begins with nutrition. Let us all enjoy good nutrition every day and a lifetime of health.
