After a woman becomes pregnant, she often has "early pregnancy reactions" such as partial eating, loss of appetite, nausea, and vomiting.
Because sour food can stimulate the stomach to secrete gastric juice, is conducive to improving the appetite of pregnant women, but also improve the activity of digestive enzymes, promote gastrointestinal peristalsis, strengthen the digestion and absorption of food, so pregnant women as long as they eat some acid to make up for the lack of stomach acid, nausea, vomiting and other symptoms can also be alleviated.
The food preferences of pregnant women are not related to the sex of the fetus
Pregnant women's preference for acidic foods is in line with physiological and nutritional needs.
After a woman becomes pregnant, the placenta of the mother and fetus will secrete a substance called chorionic gonadotropin, which has the effect of inhibiting the secretion of gastric acid, reducing gastric acid and reducing the activity of digestive enzymes, thereby affecting the digestive and absorption function of the gastrointestinal tract, causing pregnant women to have nausea, vomiting, decreased appetite and other pregnancy reactions.
Because taste can stimulate the stomach to secrete gastric juice, and can improve the activity of digestive enzymes, promote gastrointestinal peristalsis, increase appetite, is conducive to the digestion and absorption of food, so most pregnant women love to eat sour food.
In addition, the taste of pregnant women is also related to the eating habits of different regions and different families. For example, the south is sweet and the north is salty, and the west is sour and spicy, but the sex ratio of newborns does not differ significantly between regions.
The sex of the fetus is determined by sex chromosomes, and there is no scientific basis for judging the sex of the fetus only based on changes in the taste of pregnant women.
Why do pregnant women love to eat acid
From a nutritional point of view, generally after 2 to 3 months of pregnancy, the fetal bone begins to form. The main component that makes up the bone is calcium, but for free calcium to form calcium salts deposited in the bone, acidic substances must participate.
Vitamin C is also an essential nutrient for pregnant women and fetuses, the formation of cell matrix, cardiovascular growth and development, the soundness of the hematopoietic system have an important role, vitamin C can also enhance the mother's resistance, promote the absorption of iron by pregnant women, and most of the foods rich in vitamin C are acidic.
However, although artificially pickled sauerkraut and vinegar products have a certain sour taste, vitamins, proteins and other nutrients are almost lost, and the carcinogen nitrite content in pickles is high, and excessive consumption is not beneficial to maternal and fetal health.
Therefore, pregnant women who like to eat sour food, it is best to choose fresh fruits such as tomatoes, cherries, bayberry, pomegranate, oranges, sour dates, grapes, green apples and other fresh fruits that are both sour and nutritious, which can not only improve the symptoms of gastrointestinal discomfort, but also enhance appetite, strengthen nutrition, and benefit the growth of the fetus.
What are the benefits of eating acid in pregnant women
1. Like to eat acid is good for digestion
After pregnancy, the placenta will secrete a substance called chorionic gonadotropin (HCG), which has the effect of inhibiting gastric acid secretion, which can significantly reduce gastric acid, reduce the activity of digestive enzymes, and affect the digestive and absorption function of the gastrointestinal tract, resulting in nausea, vomiting, decreased appetite, weakness of limbs and other symptoms.
Because the sour taste can stimulate the secretion of gastric juice, improve the activity of digestive enzymes, promote gastrointestinal peristalsis, increase appetite, and facilitate the digestion and absorption of food, most people like to eat sour foods to inhibit the weakening of digestion brought about by HCG secretion.
2. Like to eat acid is the need for nutrition
Eating acid can meet the nutritional needs of the mother and the fetus in the abdomen. Generally, after 2 to 3 months of pregnancy, the fetal bone begins to form. The main component that makes up the bone is calcium, but for free calcium to form calcium salts deposited in the bone, acidic substances must participate.
That is to say, acidic substances can improve the solubility of calcium in the diet, facilitate absorption, and contribute to the formation and development of fetal bones. Acids can also help the absorption of iron, convert trivalent iron into divalent iron, and promote the formation of hemoglobin.
3. Like to eat acid can increase the resistance of the mother
Can increase maternal resistance is vitamin C, vitamin C can promote the absorption of iron, and the formation of fetal cell matrix, connective tissue, cardiovascular growth and development, the soundness of the hematopoietic system have an important role, and many vitamin C-rich fruits are acidic, such as hawthorn, sea buckthorn, citrus and so on.
4. Eating sour foods during pregnancy should be avoided
Pregnant women should choose tomatoes, bayberry, cherry, orange, sweet orange, grape, green apple and other fresh fruits, which are not only sour, but also nutritious.
But we must remember not to eat pickled sauerkraut or vinegar products, artificially pickled sauerkraut, vinegar products although there is a certain sour taste, but vitamins, proteins, minerals, sugar and other nutrients are almost lost, and the carcinogens in pickles nitrite content is high, too much consumption is obviously not beneficial to maternal and fetal health.
In addition, for sour hawthorn, although it is rich in vitamin C, whether it is fresh fruit or dried tablets, pregnant women can not eat more. Because hawthorn or hawthorn tablets have components that stimulate uterine contractions, it may cause miscarriage and premature birth, especially early pregnant women within 3 months of pregnancy and pregnant women with a history of miscarriage and preterm birth should not eat hawthorn.
