Hemoglobin is a special protein that gives blood its red color.
The main role of hemoglobin is to transport oxygen from the lungs to the peripheral tissues of the body, and then return carbon dioxide from the peripheral tissues to the lungs.
Low hemoglobin levels may lead to hypoxia of internal organs and tissues, causing symptoms such as dizziness, fatigue, weakness, pale complexion, difficulty concentrating, and memory loss.
Iron is a trace element in the human body, and most of the iron is found in hemoglobin. Iron deficiency is the main cause of low hemoglobin.
Regularly eating foods rich in iron, vitamin C and folic acid is the best way to replenish hemoglobin.
The best sources of iron are animal liver, blood, and red meat (beef, pork, lamb, chicken). The iron in these animal foods is heme iron, and the absorption rate is as high as 15% to 25%.
Vitamin C can promote the absorption of iron, eat more vegetables and fruits rich in vitamin C.
Vegetables and fruits rich in vitamin C include: spinach, lettuce, broccoli, peppers, tomatoes, carrots, lemons, oranges, apples, kiwi, and more.
In addition, folic acid is an important substance for the synthesis of hemoglobin, and a long-term lack of folic acid can also lead to low hemoglobin levels.
Foods with the highest levels of folic acid are broccoli, cabbage, spinach and squash.
