0-8 weeks folic acid supplement to prevent deformity;
Function: prevent fetal nerve organ defects.
Folic acid supplementation is an important means to prevent fetal neural tube malformation. Generally speaking, it is necessary to pay attention to folic acid supplementation during pregnancy. Experts suggest that folic acid tablets should be taken 3 months before pregnancy, and the best daily intake is 0.4 mg after 3 months of pregnancy.
Besides folic acid tablets, we can also eat more foods with high folic acid content every day. Folic acid is usually high in all kinds of fruits and fresh vegetables, such as lettuce, spinach, tomato, carrot, orange, strawberry, cherry, banana, etc. There are also animal livers, kidneys, poultry meat and eggs; Beans, nuts, etc. Usually pay attention to a balanced diet and eat more foods rich in folic acid, so you don't have to worry about hurting the baby who reported unexpectedly because of the lack of folic acid.
9- 12 weeks to supplement magnesium and vitamin a;
Function: promote the growth and development of the baby.
Magnesium is not only vital to the health of fetal muscles, but also contributes to the normal development of bones. The amount of magnesium intake in the first trimester of pregnancy is related to the height, weight and head circumference of the newborn.
At the same time, the whole process of fetal development needs vitamin A, which can especially ensure the health of fetal skin, gastrointestinal tract and lungs. In the first three months of pregnancy, the fetus does not store vitamin A itself, so it must be supplied adequately.
13- 16 weeks of iodine supplementation, which is needed for fetal thyroid work;
Function: to prevent the fetal baby from being stunted.
Iodine is a component of thyroxine and an important substance to maintain normal metabolism of human body. Lack of iodine in diet can reduce thyroxine secreted by thyroid gland and energy metabolism of the body. Maternal iodine deficiency during pregnancy can cause fetal thyroid hypoplasia, and children may suffer from developmental retardation, mental retardation or dementia. The daily iodine supply for adults is100-140 micrograms, and pregnant mothers and lactating mothers should increase it appropriately.
Seafood such as fish, shellfish and seaweed is the most abundant food source of iodine. Seafood such as cod, laver, mackerel, prawn, salmon, sardine, seaweed, trout and kelp is recommended for pregnant mothers to eat twice a week.
17-20 weeks vitamin d and calcium;
Function: Promote the development of fetal bones and teeth and prevent rickets.
Fetal rickets may also occur for many reasons:
First, pregnant mothers suffer from some chronic diseases, which affect the absorption of vitamin D.
Second, we don't pay attention to the nutritional balance, and the intake of vitamin D is insufficient.
Third, too little sun exposure during pregnancy.
The lack of vitamin D in pregnant mothers affects calcium metabolism and makes the maternal calcium balance unbalanced. Calcium deficiency in pregnant mothers not only affects their health, but also affects the development of fetal bones, resulting in congenital rickets. Therefore, preventing pregnant mothers from vitamin D deficiency can prevent fetal calcium deficiency. Pregnant mothers should get more sunshine, pay attention to increasing nutrition and actively treat chronic diseases.
Warm reminder:
Pregnant mothers should not take too much cod liver oil; Don't overeat longan litchi and other warm and hot products; Do not take ginseng, velvet antler, deer placenta cream, walnuts and other warm tonic things.
2 1-24 weeks iron supplement;
Function: prevent iron deficiency anemia.
If pregnant mothers are not anemic, they don't need special iron supplements. But you must eat food with high content of gooseberry, such as pig liver, fungus and dark green vegetables. It's best to drink milk every day, eat food high in tobacco once or twice a week, and eat more fruits.
Supplementing dietary fiber for 25-28 weeks;
Function: prevent constipation;
Fiber is very important to ensure the health of digestive system, and it can also reduce constipation. It also helps to maintain a stable blood sugar level. Food fiber can be divided into two types: soluble fiber and insoluble fiber. Soluble fiber can make you feel full for a longer time and let sugar enter the blood steadily. Insoluble fiber allows food to pass through the body faster, prevents constipation, and removes waste from the body by defecation. Soluble fiber mainly includes apples, beans, oats, pears and brown bread. Insoluble fiber mainly includes: fruits, green leafy vegetables, lentils and whole wheat cereals.
Eat more foods containing cellulose. If you usually eat few foods containing cellulose, you should gradually increase such high-fiber foods, otherwise your stomach will find it difficult to adapt. You can also spread the daily fiber intake on every meal you eat.
Warm reminder:
Although it is important to drink plenty of water during pregnancy, don't drink too many soft drinks, which will contain about 9 teaspoons of sugar every 340 grams.
Supplementing unsaturated fatty acids for 29-32 weeks;
Function: ensure the normal development of baby's brain and retina.
People need unsaturated fatty acids all their lives, especially during pregnancy. Omega3 and DHA in unsaturated fatty acids contribute to the development of children's eyes, brain, blood and nervous system. These elements are needed throughout pregnancy, especially in the last three months of pregnancy, when children's brains develop rapidly.
Fish is tender and easy to digest and absorb, and it is rich in phosphorus, protein and unsaturated fatty acids. Fish head is also rich in lecithin. Lecithin synthesizes acetylcholine in human body, which is a major "neurotransmitter" for transmitting information between brain neurons. So eat more fish to strengthen the brain, promote the development of fetal brain and enhance the memory of pregnant mothers.
Warm reminder:
Scientific research has confirmed that fatty acids necessary for human body, such as linoleic acid and linolenic acid, cannot be synthesized by human body itself and can only be supplied by food. These fatty acids mainly exist in vegetable oil, and the content in animal oil is very small. Lack of fatty acids in human body can cause rough skin, easily broken hair and increased dandruff, while infants are prone to eczema. In order to prevent infants from eczema, pregnant mothers should choose vegetable oil instead of animal oil.
33-36 weeks to supplement fruits and vegetables;
Function: Maintain the body's heat demand.
Vitamin B 12 and vitamin k should be supplemented in 37-40 weeks!
Function: prevent constipation and promote intestinal peristalsis.
In the last month, we must supplement all kinds of vitamins, enough iron, calcium and enough water-soluble vitamins, especially thiamine. If thiamine is insufficient, it is easy to cause vomiting, burnout and fatigue of expectant mothers, and it can also affect uterine contraction during delivery, prolong the labor process and make delivery difficult. Thiamine content in marine fish is relatively high.
