Anemia refers to a common clinical symptom of human peripheral blood red blood cell volume, which is lower than the lower limit of the normal range. Because of the complexity of red blood cell volume measurement, clinical hemoglobin (Hb) concentration is often used instead. Chinese hematologists believe that in China's sea level areas, adult male Hb <120g / L, adult female (non-pregnant) Hb <110g / L, pregnant women Hb <100g / L there is anemia.
The etiology of anemia, the degree of blood oxygen carrying capacity decline, the degree of blood volume decline, the rate of anemia, and the ability to compensate and tolerate blood, circulation, and respiratory systems all affect the clinical manifestations of anemia. The earliest symptoms were dizziness, fatigue, and drowsiness; the most common and prominent signs were pale. The severity of symptoms depends on the speed of anemia, the degree of anemia, and the body's ability to compensate.
Iron deficiency and iron use disorders affect heme synthesis, and it is said that this type of anemia is an anemia of heme synthesis abnormality. This kind of anemic red blood cell morphology becomes smaller, the central light-stained area expands, belongs to small cell hypochromic anemia. Here's a specific introduction of what foods in patients with iron deficiency anemia will aggravate the symptoms of anemia, in daily life to avoid excessive food which food?
1, coffee
Coffee contains polyphenols and salts of iron. It inhibits the absorption of iron. It is very unsuitable for anemic people. Can not drink coffee for a long time, even if you do not drink too much anemia is also a problem, if you want to drink, you can change the coffee to juice.
2, tea
Modern medical research has found that tannic acid in tea will form insoluble precipitates with ferric iron, affecting the absorption of iron in the body. In particular, drinking tea after meals will cause iron in food to be excreted due to poor absorption and cause anemia.
The iron, protein, vitamins and other substances necessary for the human body are usually ingested in the daily diet. The tea contains a large amount of tannic acid. After drinking a large amount of tea, the tannic acid and iron combine to form an insoluble substance. The absorption of iron, if you often drink strong tea after a meal, can cause iron deficiency in the body, causing iron deficiency anemia.
3, garlic
Garlic contains more active substances, excessive consumption will inhibit the secretion of gastric juice, reduce hemoglobin, red blood cells, increase the symptoms of anemia.
4, milk
Milk contains very low iron content, but calcium and phosphorus are relatively high. The iron in the body is easily combined with calcium and phosphorus in milk to form insoluble iron-containing compounds.
5, fat-containing foods
Eating too much fat-containing foods will inhibit the body's hematopoietic function. At the same time, too much fat will also affect the digestion and absorption of anaemia patients. Daily intake of fat can not exceed 70 grams, generally 50 grams best, it is best to eat vegetable oils.
6, alkaline food
The alkaline environment is not suitable for the absorption of iron. The lack of stomach acid can also affect the free and transformation of iron in food, because patients with anemia should eat less alkaline foods, such as steamed bread, soba, and other foods.
7. Indigestible food.
Patients with anemia often have digestive disorders at the same time. Eat less of the food that is not easily digested. These include peanuts, walnuts, almonds, leeks, garlic sprouts, onions, and various types of meat that are not boiled.
8. Fried food
The gastrointestinal function of patients with anemia directly affects the recovery of the disease. On the one hand, the fried food has a large number of nutritional components destroyed. On the other hand, it also affects digestion and absorption and causes intestinal dysfunction, which affects the recovery of the disease.
