Consumption of beef can supplement the body’s nutrients (such as iron, etc.), but eating beef does not have the effect of medication to replenish blood. The so-called blood replenishment, in fact, is to supplement the iron, protein, vitamin B₁₂, etc., which are the raw materials for blood production. Iron is an essential trace element, the main function is to participate in the synthesis of hemoglobin, participate in the body of oxygen transport and tissue respiratory process, to maintain normal hematopoietic function, to prevent iron deficiency anemia. The iron absorbed and utilized by the human body is divided into heme iron and non-heme iron. Among them, heme iron has a higher absorption rate and is less affected by digestive juices or other food factors. Beef contains 3.3mg/100g of heme iron, rich in protein, saturated fatty acids, linoleic acid, vitamin B₁₂ and other nutrients, which can provide raw materials for erythropoiesis, and promote the synthesis of hemoglobin, which is thus helpful to a certain extent for some anemic patients. It should be noted that food can not replace drug therapy, such as suffering from anemia and other diseases should be timely to the hospital, under the guidance of the doctor active treatment.
