In most cases, immune diseases do not require special dietary regimen, a healthy and balanced diet is sufficient. Eat more foods that improve immune function, such as lean meat, eggs, milk, etc., and foods rich in trace elements, such as yam, black sesame, ginkgo, tofu, etc., and drink more water to promote body metabolism. In case of gout and hyperuricemia patients, they need to have a low purine diet, no or less seafood and high cholesterol foods. If immune disease patients are accompanied by high blood sugar, they need to have a low sugar diet, control sugar intake, and eat less or no cakes, candies and other foods with high sugar content.
