My wife is now in the seventh week of pregnancy. Does it have to be supplemented with folic acid? Is folic acid supplementation better by taking medicine or food (which foods contain more folic acid?), and how to control the amount of supplementation?

Answer: Insufficient folic acid intake has many adverse effects on pregnancy, such as low birth weight, placental abruption and neural tube malformations. In developing countries, there are also pregnant women with giant cell anemia. About 80,000 to 100,000 children with neural tube defects are born in the United States each year. Among them, the north is higher than the south, the rural areas are higher than the cities, and the summer and autumn are higher than winter and spring. Folic acid supplementation should be started before pregnancy is planned or possible. The 2000 "Reference Intake of Dietary Nutrients for US Residents" recommended that peri-pregnancy women should consume more foods rich in folic acid. The recommended intake of folic acid during pregnancy is 600 micrograms per day. . Folic acid can be derived from liver, beans and dark green leafy vegetables, but the bioavailability of food folic acid is only 50% of supplements, so it is more effective to supplement 400 micrograms/day with beans or eat folic acid fortified foods.
