It is advisable to eat a high-protein, high-calorie diet, 1.5-20 grams of protein per kilogram of body weight per day, calories in the 2500 kilocalories, and pay attention to eat iron, copper-rich foods, such as animal liver, lean meat, egg yolks, spinach, celery, tomatoes, apricots, peaches, plums, jujubes, etc., containing more iron. Peanuts, walnuts, dry beans and poultry are rich in copper. Vitamin C can promote metabolism, help the absorption and utilization of iron, should be supplied sufficiently, eat more fresh vegetables and fruits. Roughage and vegetables contain more vitamin B and folic acid, which is beneficial to the improvement of hematopoietic function and should be eaten more. In short, after donating blood, you don't have to eat anything in particular, as long as you eat scientifically and reasonably, with nutritional value, delicious, comfortable, and in moderation, you will be able to recover the lost part of blood in a short period of time. Nutritional supplementation after donating blood is generally appropriate to increase the various nutrients necessary for hematopoiesis. The main raw materials for blood production include: protein, iron, folic acid and vitamin B12. Foods containing high quality proteins include: milk, lean meat, eggs and soy products. Foods containing more iron include: animal liver, jellyfish, shrimp, sesame, kelp, black fungus, seaweed, shiitake mushrooms, peas, jujubes, cinnamon and so on. Also, use an iron skillet for stir-frying. Foods that contain more folic acid include pork liver, kidney and beef. Foods that contain more vitamin B12 include: animal liver, pig or goat kidneys, and curd. In short, you don't have to eat anything special after donating blood. As long as you eat scientifically, rationally, nutritiously, deliciously, comfortably, and in the right amount, you will be able to regain the lost blood in a short period of time. How to move or exercise after blood donation? Do not participate in strenuous exercise or overnight recreational activities on the day after blood donation. Generally, you are supposed to donate 200cc, 400cc means you are healthier and more caring, but you need to pay more attention to rest and nutritional supplements. After donating blood one or two big should be appropriate rest, do not carry out strenuous exercise, overeating and drinking. On the basis of the usual diet can be appropriate to supplement some protein and vegetables and fruits, but do not overdo it. In recent years, hospital blood supply tension, insufficient blood source, to the surgical operation, anemic patients with blood supply to bring certain difficulties. Blood donation can save many dying patients and is a kind of public morality behavior, gratuitous blood donation is a sign of social progress and personal health. Perhaps, you have just donated blood, or are about to become a blood donor, at this time, it is very necessary to understand how to carry out dietary regimen after blood donation to better promote blood regeneration and physical health. Self-regulation of the human body after blood donation: Blood consists of plasma, blood cells, etc. It contains thousands of red blood cells, white blood cells, platelets, and a variety of electrolytes. Normal adult blood accounts for about 7% -8% of body weight, that is, about 70-80 ml of blood per kilogram of body weight, most of the blood in the cardiovascular rapid circulation flow, this part of the blood is called circulating blood volume, a small part of the blood retained in the liver, spleen, lungs and subcutaneous and other reservoirs of blood sinusoids, capillaries and venous plexus, the flow of the slow, this part of the blood is called the volume of stored blood. When strenuous exercise, emotional excitement or more blood loss, the blood in the reservoir can be released to supplement the circulating blood volume to maintain the body's needs. Under normal circumstances, the human body has its own compensatory regulation function, such as a blood loss of not more than 10% of the total body blood volume, through the body's own compensation to maintain the normal state of function and metabolism. The amount of blood donated by a healthy adult is about 200-400 milliliters, which is only equivalent to about 5%-8% of the total body blood volume, and will not affect the health of the body. Water and electrolytes in the blood can be replenished through the tissue fluids penetrating into the blood vessels after blood donation, and the liquid beverages consumed after blood donation can also play a supplementary role, so water and electrolytes can often be restored to the normal level within 1-2 hours. Donating 200-400 ml of blood can reduce plasma protein by 11-29 grams, at which time it can be compensated for in about 1 week through accelerated synthesis by the liver. After blood donation, due to the increase of erythropoietin production in the body, it stimulates the proliferation and differentiation of bone marrow hematopoietic tissues, thus accelerating the production and release of red blood cells, which can be restored in about 1 month. As the white blood cells and platelets themselves have a short survival period in the body and are rapidly renewed, they can be restored to their original level in a few days after blood donation. Dietary principles after blood donation: As can be seen from the above analysis, in addition to drinking more water, especially more electrolyte-rich beverages, it is also very necessary to replenish the nutrients needed for hematopoiesis during the short period of blood regeneration after blood donation in order to speed up the recovery of red blood cells and hemoglobin in the blood. Specifically, the following principles should be followed in the daily diet: meat, eggs, fish and milk - supplemental protein: protein is the "building material" of all human tissues, and is also the basic material that constitutes hemoglobin and red blood cells. Normal adults need about 70-100 grams of protein per day, and after donating blood, they should be provided with high-protein diets so that their daily protein intake reaches 100-120 grams. High-protein diets do not need to be prepared separately, but only need to add protein-rich foods, such as lean meat, eggs, milk, fish, beans, etc., to the original normal diet, and it is best to add such substances to breakfast or lunch. For those who are used to snacking may want to eat some egg products, grilled fish fillets or drink some milk, soy milk, etc. between meals. While consuming high-protein meals, the supply of staple foods should also be increased appropriately to ensure the utilization of protein. Animal Whole Blood - Increase Iron: Iron is an essential trace element, mainly found in hemoglobin. After blood donation, you can take in more iron-rich food as appropriate, such as animal liver, animal whole blood, livestock and poultry meat and fish. The iron in these animal foods is heme iron, which has a high absorption rate after being ingested by the human body, especially animal blood, whose iron absorption rate can reach more than 22%. And animal blood is rich in sources, low price, is a good food supplement for blood donors. Plant foods such as black fungus, kelp, sesame, etc., although the amount of iron is also high, but the iron contained in the non-heme iron, mainly in the form of trivalent iron, need to be reduced to divalent iron to be absorbed, coupled with the presence of oxalic acid, tannic acid and other substances in plant foods can be formed with the formation of insoluble precipitate of iron, further affecting the absorption of iron, so the rate of absorption is relatively low, more than 10%, therefore, the effect of iron supplementation is worse than the Therefore, the effectiveness of iron supplementation is inferior to that of animal foods. In addition to more intake of some iron-rich foods, stir-fry with an iron pan is also a good choice. Vegetables, fruits, liver and meat - intake of folic acid and vitamin B12: Although folic acid and vitamin B12 are not the raw materials for blood production, they are indispensable nutrients for the maturation of red blood cells, so they should be supplemented appropriately after blood donation. Folic acid is abundant in fresh fruits and vegetables such as kiwifruit, strawberries, spinach, lettuce, etc. In addition, liver and meat foods are also rich in folic acid: Vitamin B12 is widely found in animal foods, especially in liver, kidney, heart, meat and eggs, dairy products and fresh mushrooms. The medicinal diet after blood donation: normal people in the blood donation, in general, will not cause the symptoms of qi deficiency, blood deficiency, but appropriate to take some of the spleen, beneficial to qi, nourish the blood of the medicinal diet, for the promotion of blood regeneration is still very beneficial. The following is a list of several commonly used medicinal diets, and those who have just finished donating blood may wish to choose to eat according to their own tastes. Pork liver soup with ginseng and jujube: 15-20 grams of ginseng, 20 jujube, 50-100 grams of pork liver.
