The desire to eat spicy and sour food after pregnancy may be due to the pregnant woman’s heavy personal taste. In addition, due to the change of human chorionic gonadotropin level in the blood during pregnancy, the level of hormone secretion increases, which will stimulate the secretion of gastric juice in the gastrointestinal tract of pregnant women and make them prone to early pregnancy reaction, resulting in some pregnant women changing their dietary preferences after pregnancy and preferring spicy and sour food. Because appropriate eating some sour and spicy food can play a role in relieving pregnant women’s pregnancy vomiting reaction, and can also increase appetite. However, you should not eat a lot of spicy and sour food frequently, because the gastrointestinal tract peristaltic function is weak during pregnancy, excessive intake will lead to bloating, constipation, and easily cause stomach cramps and intestinal cramps, affecting the health of pregnant women and fetuses. Pregnant women should eat more fresh vegetables and the right amount of high-quality protein foods, such as eggs, milk, lean meat, bean products, etc., to maintain a balanced, comprehensive and diversified diet and avoid partial diet. In addition, folic acid should be supplemented in time during the first 3 months of pregnancy and early 3 months of pregnancy to effectively prevent neural tube abnormalities in the fetus.
