Hello, this friend: First of all, I wish you good health and happiness. Tophus is a disorder of purine metabolism. The attack of gout is related to diet. Food contains purine. After purine enters the body, it will lead to purine metabolism disorder, renal excretion function decline, joint tissue damage and gout. Want to know which food contains the most purine? What food can be eaten and what food can't be eaten? Let me talk about foods containing trace amounts of purine, such as milk, cheese, eggs, vegetables, rice, millet, flour, potatoes, honey, tea, cocoa, coffee, pears, grapes, oranges and so on. Foods containing a moderate amount of purine include Gracilaria lemaneiformis, kidney beans, mushrooms, spinach, peas, winter bamboo shoots, tremella, cereals, peanuts, cashews, sesame seeds, chicken, mutton, eels, salmon, white fish, grass carp, tuna, crabs and lobsters. Foods with high purine content (try not to eat them) include beef, beef tongue, pork, mutton, turkey, duck, goose, chicken soup, lentils, mushrooms, laver and wine (especially beer). Viscera, roe, hot pot soup, thick juice, shellfish, shrimp, crab roe and bean products with extremely high purine content are forbidden.
