Pulmonary solidification refers to a lesion caused by the accumulation of plasma, fibrin and cellular components in the alveolar cavity for any reason, resulting in a decrease in alveolar air content and densification of the lung texture. It is often accompanied by sputum and cough, shortness of breath and chest pain, etc. It is a strict diet for patients. A good diet ensures that the patient consumes enough fluids and calories to help with treatment. So, what dietary principles should be followed by patients with solid lung changes? Dietary principles: 1, the patient’s daily diet, more high-quality protein-rich foods, such as: lean meat, crabs, sea fish, dairy products, soy products, eggs, etc., to improve immunity from the attack of foreign pathogens. 2.Patients with solid lung change often have water, electrolyte and acid-base balance imbalance in their bodies, so they should eat foods rich in iron, such as animal liver, egg yolk, etc.; and foods with high copper content, such as beef liver, sesame paste, pork, etc. High-calcium foods such as shrimp and dairy products can also be given. 3. For patients with solid lung, it is recommended that they should eat more vitamin A foods in their daily life, and animal liver and egg yolk are good choices. At the same time, these foods have a very good conditioning effect on the integrity of the respiratory tract of patients with pneumonia, which is very helpful for the patient’s condition.
