Red dates and donkey-hide gelatin do not replenish blood! Reminder: These 3 kinds of foods that really nourish blood, don't waste money
Since October last year, Ms. Yang found that her hands and feet were weak, and the initial examination by the hospital was caused by anemia . But after more than half a year of conditioning, Ms. Yang's fatigue still hasn't improved. She even felt laborious when she climbed the stairs recently.
Due to shortness of breath, Ms. Yang went to the hospital again for examination and found that Ms. Yang's hemoglobin was only 41 grams per liter, which was a severe anemia .
The doctor suspected that her fecal occult blood was positive, so she arranged a colonoscopy, and it was found that there was indeed a tumor in the intestinal lumen. Behind the anemia, colon cancer was actually at work.
Many people are familiar with "anemia", and they think it is a trivial matter and normal. For example, I often hear "I just squatted for a while and felt dizzy, this must be anemia."
1. After squatting down, I get dizzy again, is it anemia?
Many people will have this experience, squatting for a long time, or sitting in one position for a long time, suddenly get up, or feel a burst of dizziness.
Although the symptoms of dizziness do appear in anemia, generally speaking, there is not much change with the change of body position . It is often accompanied by fatigue, drowsiness, and the most prominent sign is pallor.
Dizziness caused by this condition may be related to these two diseases:
· Otolithiasis
"Small stones" appear in the ear, known as otolithiasis. The otolith is a very small structure. Normally, the otolith is located in the utricle in the upper and posterior part of the vestibule of the inner ear. When stimulated by certain factors, the otolith will break away from its original position and roll into the semicircular canal.
The semicircular canal mainly manages the balance of the body. When the otolith falls off, it will directly affect the flow of ear fluid and provide wrong information to the balance nerve, which may cause dizziness, which generally lasts no more than 1 minute .
· Orthostatic hypotension
Mainly due to people squatting or sitting, the waist and legs are bent for a long time, the blood vessels are compressed, and the blood is not smooth. When a person suddenly stands up, the pressure is relieved, and the blood flows to the waist and legs. Temporary insufficiency of blood supply to the brain, resulting in a feeling of dizziness.
2. 5 symptoms or suggest anemia
Living conditions are getting better and better, but more and more people are anemia. About one-fifth of the patients in the world belong to iron-deficiency anemia, which is recognized by the World Health Organization as one of the four major nutritional deficiencies.
Most of the causes of anemia are malnutrition . When the body lacks a certain nutrient element, it may face anemia. However, the occurrence of anemia may also be related to cancers such as gastric cancer, colon cancer, multiple myeloma, lymphoma, and lung cancer. According to statistics, when these cancers occur, the incidence of anemia can reach 50%-60%.
For anemia caused by tumors, it is often impossible to find the relevant cause. Because the spread of cancer cells requires a lot of blood support, the degree of anemia is often very high. If the anemia is accompanied by other symptoms, such as epigastric discomfort, yellowing, itching, difficulty swallowing, fecal occult blood, etc., the possibility of pointing to the tumor may be high.
According to He Zhiying, an attending physician in the Clinical Nutrition Department of the Third Affiliated Hospital of Guangzhou Medical University, anemia is a common health problem for infants, children, pregnant women, the elderly, thin people, vegetarians and patients with digestive system diseases.
When anemia occurs, the hemoglobin decreases and the whole body is deprived of oxygen to varying degrees. Therefore, the most common symptom is "pale skin" . The early subjective symptoms include fatigue, weakness, dizziness, memory loss, etc. Severe anemia can also cause symptoms of shortness of breath and heart palpitations. .
When the harm of chronic severe anemia is serious, it may cause heart enlargement and heart failure, as well as nausea, anorexia, abdominal distension, menstrual disorders, amenorrhea, nausea and other symptoms.
The severity of anemia symptoms is closely related to the speed of anemia. If the process is slow and the symptoms are mild, most of them are mild anemia. However, since most of the anemia is secondary to other diseases, the patient will also show the symptoms of the primary disease. Therefore, the above symptoms cannot be used to determine whether the anemia is anemia, but also the hemoglobin concentration.
The measured value of hemoglobin: less than 120g/L for adult men and less than 110g/L for adult women, and the hematocrit is less than 0.42 and 0.37, respectively, which can be diagnosed as anemia.
3. Can eating brown sugar and donkey-hide gelatin nourish blood?
Anemia is not an independent disease, but a clinical syndrome composed of a group of symptoms, which needs attention. Anemia occurs and needs to be remedied for the cause.
Among the anemias, the most common is iron deficiency anemia, and the main method of treatment is to take iron supplements. In the diet, eat more foods containing heme iron, followed by foods rich in plant-based iron and vitamin C.
Does eating brown sugar and donkey-hide gelatin really nourish blood?
Brown sugar is refined sugar, 96.6% of which is sugar , and contains very little iron. Drinking brown sugar water will only add sugar, but not blood.
Ejiao is made from donkey skin, and its main ingredient is collagen . The collagen contained in it cannot meet the amino acid needs of the human body. Eating Ejiao can only satisfy the taste and cannot achieve blood replenishment.
The most important thing for blood supplementation is iron supplementation . There are two rules for iron supplementation: the ease of iron absorption by the human body is animal>plant, and the degree of iron supplementation effect of animal food is red>white, that is, these foods are more suitable for blood supplementation.
Red meat: including pork, beef, and mutton, are rich in hemoglobin;
Animal blood : All kinds of animal blood contain a high amount of blood red unilateral iron, which is also beneficial to the human body to absorb;
Animal offal : For example, pig liver, the iron content reaches 22.6 mg per 100 grams. A small amount of animal offal can also help nourish blood.
Anemia is not exclusive to "thin people". There are many reasons for anemia, and it may also be the manifestation of some tumors. Therefore, when anemia occurs, do not take it lightly and find out the cause. For the general population, iron-containing foods should be eaten daily to prevent anemia.
