These foods mainly include lean meat, eggs, animal liver, kidney, spinach, tomatoes, kelp, laver, fungus, jujube, beans and their products. In addition, we should eat more foods rich in vitamin C, which can reduce the permeability and brittleness of capillaries. Patients should eat more of these foods to help them recover. Foods rich in vitamin C include grapefruit, oranges, tangerines, apples, lemons, strawberries, kiwis, tomatoes and various green leafy vegetables. It is worth noting that the diet of patients with henoch-schonlein purpura should not only supplement various nutritious foods, but also try to make the food light.
