Pregnancy is one of the most critical times in a woman’s life when proper nutrition directly impacts both maternal health and fetal development. A well-balanced diet not only supports your baby’s growth but also helps reduce the risk of complications such as low birth weight, birth defects, and preterm labor. Knowing what to eat—and what to avoid—can make all the difference.
This guide outlines the essential nutrients, healthy food choices, and important restrictions every pregnant woman should know.
Why Nutrition Matters in Pregnancy
Your baby relies entirely on you for nutrients. Every bite you take fuels the development of the baby’s brain, bones, organs, and immune system. Meanwhile, your body needs additional energy to support increased blood volume, hormonal changes, and the placenta.
Failing to meet these nutritional demands can lead to deficiencies, fatigue, slow fetal growth, or pregnancy-related conditions like anemia or gestational diabetes.
