Nutritional support for critically ill patients with neoconiosis is beneficial for recovery. If the patient is able to eat, consider small and frequent meals, 6-7 times a day, with liquid food that is easy to swallow and digest. The main ingredients are eggs, soy and its products, milk and its products, fruit juices, vegetable juices, rice flour, etc. Pay attention to the priority of supplementing adequate amount of food containing high quality protein. In the process of gradual remission, semi-liquid food that is easy to chew and digest can be consumed, and gradually transition to ordinary meals as the condition improves. If the nutritional needs cannot be met by food alone, enteral nutrition preparations can be used again.
