I don't know when, the iron wok has become a healthy choice for people.
Many people think that cooking is to use an iron pot, stir-fry the aroma, but also to replenish blood...
This kind of statement really makes me really can't listen to it.
Iron pot, really may play a role in tonifying blood?
If you can really replenish blood, then can't anemia patients buy a big iron pot to eat stir-fried vegetables without going to the hospital?
In fact, the iron pot stir-fry is indeed able to increase the iron content in the dish, the iron on the wall of the pot in the shovel rubbing, it is inevitable that there will be a trace amount of detritus falling into the dish, contact with acidic substances in the food, it will become iron ions, increase the content of iron.
However, this iron is mainly inorganic iron, and the iron that the human body is most easily absorbed and utilized is heme iron, so the iron in the iron pot is actually not of great significance for improving anemia and blood replenishment.
Stir-frying in an iron pot, the iron added in the dish is trivalent iron, this iron is not easy to be absorbed and used, so using an iron pot to supplement iron is not as effective as eating meat directly.
What symptoms occur when the body is deficient in iron?
Iron is very important in both the human body and plants, and plant iron deficiency will cause young shoots to lack green and yellow. Iron is more important to the human body, sometimes a little missing, there will be obvious symptoms in the body.
Iron deficiency can have many manifestations, such as waking up from sleep, anorexia, and dizziness. The most typical of these is iron deficiency anemia, which is a systemic nutritional deficiency disease.
Mild patients may experience symptoms such as inattention, dizziness and tinnitus, while children present with slow development.
More severe cases will also appear nausea and vomiting, heart failure and other symptoms. In addition to iron deficiency anemia, it may lead to dysphagia syndrome, which can manifest as dysphagia and abnormal sensations on the tongue.
Why does the human body have iron deficiency anemia?
1. Insufficient intake of iron
Insufficient intake of iron is a reason why people have a large proportion of deficiency anemia in their lives.
However, the lack of iron in people's bodies is mainly due to the lack of comprehensive intake of nutrients and the lack of diet diversification.
This situation occurs mostly in women who lose weight and adolescents who are picky eaters, so people need to eat iron-rich foods such as pork liver and beef appropriately in their lives, and long-term adherence can effectively alleviate the symptoms caused by iron deficiency anemia.
2. Pregnant women are not fully nourished
Pregnant women are a special group of people in iron deficiency anemia.
Pregnant women during pregnancy, the body to take double nutrition, on the one hand, so that the body can maintain normal life activities, on the other hand to provide nutrition for the fetus in the womb.
Once pregnant women do not adjust their diet in time according to their own situation, it will lead to insufficient nutrition in the body and cause iron deficiency anemia, which will have a certain impact on the fetus.
3. Women have too much menstruation
Too much blood lost in the body can also cause too much iron to be lost.
Under normal circumstances, a more serious accident or a situation in childbirth may cause heavy bleeding, and then the common is that women will lose blood every month during menstruation.
Normal women's menstrual flow is between 20ml and 60ml, but women may have excessive menstruation due to physical reasons or cysts inside the uterus.
Excessive menstrual flow will lead to the loss of iron too quickly, and in the long run, it will cause the body to aggravate iron deficiency anemia.
When a woman has menstrual problems, she needs to see a gynecologist in time.
4. Hemorrhagic urine or bloody stool
Abnormal bowel movements are also a sign of iron deficiency anemia.
If people excrete hematuria or bloody stools in their lives, it is likely that the digestive tract in the stomach and intestines is abnormal, resulting in the renal tubules not fully absorbing the elements in the blood.
At this time, people are eager to supplement iron, it is easy to increase the burden on the stomach and intestines, resulting in gastrointestinal dysfunction, and there may be ulcers, which can not play a role in improving anemia.
If you want to subsidize, you still have to start with diet
Iron is usually divided into heme iron and non-heme iron.
The heme iron comes from lean pork, beef, animal liver and other animal foods, and its absorption rate can reach 15%-35%, which is easily absorbed by the human body.
The iron in plant foods is mainly non-heme iron, and the absorption rate is relatively reduced, usually below 10%.
Therefore, if it is due to iron deficiency anemia, the better food choice should be red meat.
