Document Summary
Chapter 10- nutrition through the life span: pregnancy and lactation. Pregnancy: the impact of nutrition on the future. Adequate nutrition before pregnancy establishes physical readiness and nutrient stores to support fetal growth. Both underweight and overweight women should strive for appropriate body weights before pregnancy. Newborns who weigh less than 5 pounds face greater health risks than normal-weight infants. The healthy development of the placenta depends on adequate nutrition before pregnancy. Placental development, implantation, and early critical periods of embryonic and fetal development depend on maternal nutrition before and during pregnancy. The effects of malnutrition during critical periods are irreversible. A balanced diet that includes more nutrient-dense foods from each of the five food groups can help to meet the increased nutrient demands of pregnancy. Due to their key roles in cell reproduction, folate and vitamin b12 are needed in large amounts during pregnancy. Folate plays an important role in preventing neural tube defects.
