Allergic purpura children during the onset of the body is in a highly sensitive state, the original non-allergic food (such as meat, milk, eggs, vegetables, soy products and fruits, etc.) and some items (such as flowers, new clothes, new books and newspapers, dust, chemicals, etc.), at this time can cause allergic reactions and thus aggravate the disease. Therefore, diet and life management are very important. Parents should give their children reasonable diet and life care under the guidance of doctors. 1. Add animal protein diet After the rash has subsided for 2 to 4 weeks, consider adjusting the diet and adding animal protein foods. The order of addition is divided into three stages: Stage 1 (meat, except lamb): the principle of adding variety and quantity of food is gradually increased. The order of species is pork → chicken → duck → beef, that is, species 1 (such as pork) added 5-7 days after no rash recurrence, then start adding species 2 (such as chicken), species 2 (such as chicken) added 5-7 days after no rash recurrence, then start adding species 3 (such as duck), and so on. The amount of food should be from a small amount → medium amount → random. After 1 month of adjustment in the first stage, if the disease is stable, you can enter the second stage. The second stage (eggs and milk): the principle of adding is mainly based on a gradual increase in food quantity, the order of varieties is eggs first, then milk, and the observation time is also 5-7 days. The third stage (fish and shrimp, mutton): the addition time should be considered at least 6 months to 1 year after the condition has stabilized. 2. Which vegetables, fruits and grains can be consumed? If there are no digestive symptoms, such as abdominal pain, blood in stool, vomiting, etc., most vegetables, fruits and grains can be eaten, but appropriate attention should be paid to the amount of vegetables such as cilantro, celery, garlic, etc. and southern fruits eaten. Encourage more tofu, soy milk, soy products, etc., to supplement vegetable protein. Seasonings such as onion, ginger and garlic can be cooked, but vegetable oil (such as peanut oil, corn oil, olive oil, etc.) must be used in the cooking process. 3. Try to eat semi-liquid food and easily digestible food, and control the amount of food appropriately. It is recommended to eat less and more meals to avoid abdominal pain and purpura recurrence due to indigestion.
