When is the best time to start preparing for pregnancy? Three months in advance is the best

　　I believe many young people are preparing to become pregnant female I don’t quite understand how far in advance I need to prepare for pregnancy. In fact, there is a best time to prepare for pregnancy, so when is the best time to start preparing for pregnancy? Let’s take a look.

　　It is recommended that it is more appropriate to prepare for pregnancy three months in advance. This is supported by certain scientific evidence for the following reasons:

　　1. Because of eggs

　　A woman usually only releases one mature egg in a month. An egg can survive for about 48 hours after being released. During these 48 hours, it is waiting to be with the egg. sperm Encounter, combine. However, many people don’t know that before the egg is released, it has to go through a long growth and development process: a healthy High-quality eggs require an 85-day growth cycle.

　　There are 3-11 eggs that mature together. However, during this process, after layers of selection, one or more dominant follicles will eventually be discharged, and the rest will undergo apoptosis and degenerate on their own. This growth cycle requires 3 menstrual cycles. Therefore, during the competition for the growth of these follicles, women preparing for pregnancy need to carry out all-round physical conditioning.

　　2. Because of sperm

　　The egg needs an 85-day growth cycle, but what about the sperm? male Sperm is produced in the testicles. It develops from spermatogonia into spermatocytes and then into real sperm. The whole process requires a growth cycle of 72-90 days. That is to say, when the sperm enters the female body, it is actually sperm that began to develop 90 days ago. It is not difficult to explain why men should prepare for pregnancy three months in advance, stay away from tobacco and alcohol, and exercise more.

　　3. Because cells metabolize harmful substances in the body

　　Three months is also a cycle for cells to metabolize harmful substances in the body. Any drugs, toxic substances, adverse factors, etc. that have an impact on reproductive cells should be completely eliminated and disappeared from the body before recreating a human in nearly 3 months. For example: Conceiving after 3 months of quitting smoking and drinking, etc.

　　Non-smokers have a greater chance of conceiving than smokers. Smoking not only affects physical health, but also affects fertility. Therefore, men and women who are preparing for pregnancy should quit smoking.

　　4. Because of folic acid

　　As we all know, the standard dose of 0.4mg folic acid is preventive fetus nerve The role of tube deformity. However, due to Chinese people’s eating habits, Chinese women generally lack folic acid, and changing this folic acid deficiency cannot be effective in a day or two. Moreover, in real life, most women know that they are pregnant after more than 30 days of pregnancy. If they supplement folic acid at this time, they have missed the critical period for preventing neural tube defects.

　　Therefore, the Chinese Nutrition Society recommends starting to take it 2 to 3 months before pregnancy and continuing to take it until the third month of pregnancy or throughout the pregnancy. In addition to preventing neural tube defects, it also helps reduce the risk of hyperlipidemia in pregnancy. In addition, insufficient folic acid will reduce the concentration of semen and may also cause abnormal chromosome segregation in sperm, which will cause serious diseases to future babies. disease possibility. Therefore, it is best for men and women preparing for pregnancy to start supplementing with folic acid 3 months before pregnancy.

　　What foods should not be eaten before pregnancy?

　　1. Spicy food

　　This type of food can cause digestive disorders in normal people, such as stomach discomfort, indigestion, constipate , and even hemorrhoids occur. In the three months before pregnancy, both expectant mothers and expectant fathers should stop eating spicy food.

　　2. High-sugar foods

　　During pregnancy preparation, try to avoid eating high-sugar foods to avoid causing sugar metabolism disorders and even becoming a potential diabetic patient. After pregnancy, if pregnant women continue to maintain the habit of eating high-sugar foods, it will lead to gestational diabetes.

　　3. Pickled foods

　　Pickled foods contain large amounts of nitrite, phenylpyrene, etc., which are very harmful to the body. Especially pregnant women with allergies should avoid eating such foods to avoid irreversible effects on the fetus.

　　4、coffee due to food

　　Women must pay attention to avoid eating foods containing caffeine while preparing for pregnancy. Excessive consumption of coffee, tea, and other caffeinated beverages and foods will affect women's physical health.

　　5. Canned food

　　A large number of additives are usually added to canned food during the production process. Although these additives have little effect on the human body, if they are eaten regularly by pregnant women, they will affect the fetus's absorption of nutrients. Therefore, canned food is also something that women need to avoid during pregnancy.

　　6. Alcoholic drinks

　　drinking causes baby An important cause of malformation and mental retardation. Alcohol can pass through the placenta and enter the fetus without any hindrance, making the alcohol concentration in the fetus the same as that in the mother. And alcohol is very harmful to the brain and heart. (Reference website: Qili Fashion Network)
