What nutritious foods should be eaten at each stage of pregnancy? Pregnancy is a critical period for the growth and development of the baby, so the dietary nutrition of pregnant women is very important. Pregnancy is divided into three stages: early, middle and late. Each stage has specific nutritional needs and the intake of certain foods should be appropriately increased. The following are nutritional foods that should be paid attention to in the three stages. Pregnant women in the early stages need to supplement nutrients such as folic acid, niacin, vitamin B6, vitamin C and vitamin E. Folic acid is very important for the development of the baby\’s neural tube. If it is deficient, it can easily lead to fetal neural tube defects.
