The diet of patients with tuberculous pleural fluid is not very different from that of patients with tuberculosis. Because TB, regardless of its location, is a wasting disease that draws nutrients from the body, supplementation is important. The dietary principle is a high-protein, high-vitamin diet. A high-protein diet includes all kinds of meat, such as chicken, fish and pork, as well as milk and eggs. A high vitamin diet includes a variety of fresh vegetables and fruits. Patients with tuberculous pleurisy are prone to hyperuricemia when taking anti-tuberculosis drugs, so patients are advised to minimize the intake of animal offal, seafood and soy products. Patients with allergies should try to avoid taking foods that they have not eaten before, and try to avoid the appearance of food allergies that can lead to interruptions in the use of anti-tuberculosis drugs. Patients should be careful not to take anti-tuberculosis drugs with milk, which can be taken at intervals. Patients should try not to eat spicy, stimulating, or greasy foods. Because tuberculosis is usually considered a “poor disease”, that is, the less developed the economy, the lower the standard of living of the people, so the less nutrition, the lower the resistance, the higher the incidence of tuberculosis. Therefore, with the gradual development of our economy, there will be fewer and fewer people suffering from TB in the future.
