Which nutrient is crucial for fetal development during pregnancy?

Folic acid is crucial for fetal development during pregnancy primarily because it plays a significant role in DNA synthesis and cell division. This nutrient is especially important in the early stages of pregnancy, as it helps prevent neural tube defects, which can occur when the neural tube, which develops into the baby's brain and spinal cord, does not close completely. Adequate folic acid intake is essential for forming the basic structures that will support the baby's neurological development.

In addition to its role in preventing defects, folic acid supports the growth of the placenta and helps ensure a healthy supply of nutrients to the developing fetus. Women who are planning to become pregnant or who are in their early pregnancy are often advised to take folic acid supplements to meet the increased demands for this nutrient during this critical time.

While nutrients such as calcium, iron, and protein are also important for overall health during pregnancy, and contribute to other aspects of fetal growth and maternal well-being, folic acid's specific role in preventing congenital issues makes it particularly vital during the early stages of fetal development.
