The reason why mung bean sprouts have higher purine than meat is that mung bean sprouts are legume products.
Mung bean sprouts are a high-purine food, because all soy products are high-purine foods. Purine mainly exists in the form of purine nucleotides, and both DNA and RNA contain purine nucleotides. DNA and RNA play key roles in living organisms, so purine is generally present in cells. Even if some viruses exist in the form of RNA, they also contain purine.
Foods high in purine include: liver, kidney, pancreas, heart, brain, minced meat, gravy, broth, mackerel, anchovy, sardines, fish eggs, shrimp, mussels, Goose, spotted chicken, pheasant, beans, yeast, mushrooms, seaweed, etc. Foods without purine or containing low purine include: refined flour, rice, soda crackers, steamed buns, bread, milk and milk products, eggs, various fats and oils, fruits, dried fruits, sugar and candies.
