A healthy diet in pregnancy is needed to help the baby develop and grow.

Here's why:

1. Prevent miscarriage: While a healthy diet is important for overall health and wellness, it's not directly linked to preventing miscarriages. Miscarriages are often caused by chromosomal abnormalities, not diet.

2. Prevent birth defects: Certain nutrients like folic acid can help prevent certain birth defects like neural tube defects. However, a healthy diet alone cannot prevent all types of birth defects as they can be caused by a variety of genetic and environmental factors.

3. Help the baby develop and grow: This is the most accurate answer. A healthy diet provides the necessary nutrients for the baby's development and growth. This includes proteins for growth, calcium for bone development, and iron for blood supply.

4. Preserve the baby: This statement is a bit vague, but a healthy diet can certainly contribute to the overall health and well-being of the baby. However, it's not the only factor. Regular prenatal care, avoiding harmful substances like alcohol and drugs, and managing chronic conditions are also important.
