It is difficult to increase the number of leukocytes in the body only by consuming a certain kind of food or several kinds of food, but increasing the intake of high protein food and vegetables appropriately can help the synthesis of leukocytes, and more importantly, it is necessary to deal with the etiology of leukocyte lowering. 1. Protein-rich foods. Protein is the material basis for leukocyte synthesis, so if you want to effectively increase the number of leukocytes, it is essential to maintain a sufficient amount of protein intake. In daily life, eggs, chicken and other foods are rich in high quality protein. 2. Fresh vegetables. Vegetables contain folic acid, which also plays an irreplaceable role in the synthesis of white blood cells, so it is also very important to supplement with appropriate vegetables such as spinach, green vegetables and so on. The above foods can help the body synthesize white blood cells to a certain extent, but if the patient’s white blood cells are seriously lower than normal or if the patient has related symptoms, it is recommended to consult a doctor in a timely manner to find out the cause of the disease and carry out the relevant diagnosis and treatment, and food can not replace the role of drugs.
