There is no relevant scientific evidence to prove that pig’s blood can lower uric acid. Most of the high uric acid is caused by diseases, excessive production of uric acid and drugs, etc. Patients with high uric acid should try to eat a low-purine diet in their daily life, avoiding animal offal, duck, seafood and other high-purine diets and limiting purine diets and increasing the daily water intake, and every 100g of pig’s blood contains only 11.8mg of purine, which is a low-purine food. Patients with high uric acid can consume pig’s blood appropriately, which generally does not cause fluctuations in blood uric acid concentration in the body, in addition to pig’s blood also contains iron, phosphorus, calcium, protein and other nutrients, which can effectively replenish the body’s required nutrients, therefore, patients with high uric acid can consume pig’s blood, but the consumption of pig’s blood can not play a role in lowering the concentration of blood uric acid level. It is recommended that patients with high uric acid should go to endocrinology, rheumatology and immunology, nutrition and other related departments in regular hospitals to get professional dietary advice or treatment advice, and should not listen to biased prescriptions for self-treatment.
