Proper nutrition is essential for the health and development of both the mother and the baby during pregnancy. A balanced and healthy diet that includes essential nutrients such as protein, folic acid, iron, and calcium, can help prevent complications such as gestational diabetes, pre-eclampsia, and low birth weight. Pregnant women should aim to consume a variety of foods from all food groups and should avoid certain foods that can be harmful to the developing baby, such as raw or undercooked meats, fish, and eggs. It is also important to limit caffeine intake and avoid alcohol and smoking. A prenatal vitamin supplement can also help ensure that the mother and baby are getting adequate nutrition.
