Typically, pregnant women eat sour taste in early pregnancy of food, which is a normal physiological phenomenon, but there are still many people worry about it. As to why pregnant women eat acid, from a series of physiological changes after pregnancy begins, the following three main reasons:
(1) early stages of pregnancy, significantly reduced gastric acid secretion, reducing the activity of digestive enzymes, so that pregnant women experience nausea, vomiting Zone 0, loss of appetite and other symptoms. Sour food can stimulate gastric acid secretion, increased the activity of digestive enzymes to promote gastrointestinal motility, is conducive to digestion and absorption of food, so pregnant women to eat acidic food, nausea, vomiting and other symptoms can be different degrees of ease, appetite increased significantly.
(2) 2 ~ 3 months of pregnancy, the fetal skeleton begins to form, constitute the main component of bone is calcium, but to make free calcium deposited calcium into bone formation, there must be involved in acidic foods, so pregnant women to eat acidic foods help fetal bone growth and development.
(3) pregnant women to eat acidic food is conducive to the absorption of iron, promoting the formation of hemoglobin. Vitamin C is necessary for maternal and fetal nutrition, fetal form of its matrix production of connective tissue cells, and hematopoietic growth and development of the cardiovascular system have an important role in the sound. Vitamin C can enhance the mother's immunity, and promote women on iron absorption and utilization, and food rich in vitamin C are mostly acidic, therefore, pregnant women eat sour food for themselves and the fetus can provide more vitamin C. In addition, iron is an essential trace element, is an indispensable raw material for manufacture of hemoglobin, and pregnant women tend to occur in iron deficiency anemia during pregnancy. Only in acidic conditions, ferric iron can be changed by the divalent iron is absorbed by the gastrointestinal. Therefore pregnant women to eat acidic foods help to correct iron deficiency anemia.
Hi pregnant women to eat acidic food, the best choice for both sour and nutritious foods such as tomatoes, cherries, grapes, red bayberry and other fresh fruit. This can improve gastrointestinal symptoms after pregnancy can also increase appetite, nutritional supplements.
Pregnant women addicted to food acid and fetal development of their own food needs, is self-protection, survival and development needs to adapt to a compensation, therefore, do not take it as a strange phenomenon.
