There is no scientific basis for the claim that oxtail soup replenishes white blood cells. Oxtail soup belongs to the Cantonese cuisine Guangfu soup, is a traditional local delicacy in Guangdong Province. The main ingredient of oxtail soup is oxtail, which has no special effect on elevating white blood cells, but can supplement the nutrients needed by the human body. The nutrients of oxtail mainly include protein, fat, carbohydrates and various trace elements and vitamins, etc. Taking canned oxtail soup as an example, every 100 grams of oxtail soup contains 44 calories, of which 2.4 grams of protein, 1.7 grams of fat, 5.1 grams of carbohydrates and 40 milligrams of calcium. Appropriate consumption of oxtail soup is beneficial to one’s health, but as a food, oxtail is no medicinal effect, much less a substitute for medicine. General healthy people do not need to supplement white blood cells, but if it is a blood disease or after chemotherapy and other patients with the need to elevate white blood cells, should go to the hospital, under the guidance of specialists to take relevant drugs for treatment.
