Generally, an adult has 4000 ml of blood, and the amount of blood donated each time is only 200 ml, accounting for only 5% of the total blood volume. In addition, blood drawn from peripheral blood vessels will automatically release blood originally stored in internal organs such as spleen and liver into blood vessels to maintain a constant blood volume, so blood donation will not affect the health of blood donors.
After blood donation, the hematopoietic tissue of the human body will automatically accelerate hematopoiesis, and generally it will return to its original level after half a month. Within half a month after recovery, blood donors should appropriately increase nutrition to provide enough hematopoietic materials, with emphasis on protein, iron, vitamin B 12, folic acid, etc.
It is suggested that you eat 300-400g grain, 1-2 eggs, 50- 100g fish, shrimp, lean pork, 50g bean products, 50g pig blood (or chicken blood or duck blood), 200-250ml milk and 400-500g vegetables every day during the recovery period. While supplementing nutrition, we should also pay attention to maintaining a certain amount of activity and adequate sleep, so that the body can be adjusted to its original healthy state as soon as possible.
It is worth reminding that if you take a large amount of supplements and are inactive, it will be detrimental to the digestion and absorption of nutrients, cause gastrointestinal dysfunction, or gain weight due to excessive calories.
Scientific and reasonable blood donation is not only harmless to the body, but also beneficial to health. Blood donation can promote blood circulation, reduce blood lipid, dilute viscous blood and reduce the hidden danger of arteriosclerosis. However, after blood donation, it is necessary to supplement nutrition in time and restore health.
Healthy adults donate about 200 ml of blood at a time, which only accounts for about 5% of the whole body's blood volume and does not affect their health. As long as the nutrients needed for hematopoietic function are supplemented reasonably and timely, this 5% blood can be supplemented soon.
Blood consists of plasma, blood cells, etc. It contains thousands of red blood cells, white blood cells, platelets and various organic components. Hematopoietic raw materials mainly include protein, iron, copper, folic acid and multivitamins, which are widely found in food.
Protein: Pay attention to supplementing protein after blood drawing, especially some high-quality protein, such as milk, lean meat, mutton, eggs, fish and soybeans, which contain a lot of nutrients needed for hematopoiesis.
Folic acid and vitamin B 12: widely distributed in green leafy vegetables and coastal areas. What happened to mother? Diarrhea? Hey? Crabs can stimulate the hematopoietic function of bone marrow. Therefore, we should pay attention to the intake of these foods after donating blood.
Iron: Foods rich in iron include lean meat, animal liver, fish, bean products, red dates, laver and so on. It is worth mentioning that iron in animal food is more easily absorbed than that in plant food, especially in animal blood, where the iron absorption rate is as high as 22%. Animal blood is rich in resources, cheap and good, and it is a good product for enriching blood.
Don't overeat for a few days after blood donation, especially eating a lot of high-protein food and greasy food, which will not achieve the expected effect. Instead, we should pay attention to rest, supplement as needed, and gradually supplement. Chocolate is not a good medicine for enriching blood; Not suitable for eating more.
