Protein: protein is the "building material" of all human tissues, and it is also the basic substance of hemoglobin and red blood cells. Normal adults need about 70- 100g protein every day. Give them a high-protein diet after blood donation, so that their daily intake of protein can reach 100- 120g. A high-protein diet does not need to be prepared separately, but only foods rich in protein, such as lean meat, eggs, milk, fish and beans. , should be added to the original normal diet, and this kind of substance is best added to breakfast or lunch. Friends who are used to eating snacks may wish to eat some egg products, roast fish fillets or drink some milk or soybean milk between meals. While adopting a high-protein diet, we should also appropriately increase the supply of staple food to ensure the utilization of protein.
Animal whole blood-increasing iron: iron is an essential trace element for human body, which mainly exists in hemoglobin. After donating blood, you can eat more iron-rich foods, such as animal liver, animal whole blood, livestock and poultry meat, fish and so on. The iron in these animal foods is heme iron, which has a high absorption rate after being ingested by human body, especially in animal blood, and its iron absorption rate can reach more than 22%. Moreover, animal blood is rich in sources and low in price, which is a good food supplement for blood donors. Plant food, such as auricularia auricula, kelp, sesame, etc. It has a high iron content, but the iron contained is non-heme iron, which mainly exists in the form of trivalent iron, and can only be absorbed if it is reduced to divalent iron. In addition, oxalic acid, tannic acid and other substances in plant foods can form insoluble precipitation with iron, which further affects the absorption of iron, so the absorption rate is low, mostly below 10%. Besides eating more foods rich in iron, it is also a good choice to stir-fry in an iron pan.
Intake of fruits, vegetables, liver and meat-folic acid and vitamin B 12: Although folic acid and vitamin B 12 are not raw materials for hematopoiesis, they are indispensable nutrients for red blood cell maturation. Therefore, blood donation should be supplemented appropriately. Fresh fruits and vegetables such as kiwi fruit, strawberry, spinach and lettuce are rich in folic acid. In addition, liver and meat foods are also rich in folic acid: vitamin B 12 is widely found in animal foods, especially in liver, kidney, heart, meat and eggs, dairy products and fresh mushrooms.
