Frequently Asked Questions about Pregnancy and a Healthy Diet Why is a healthy diet important before and during pregnancy? What you eat every day, even before you are pregnant, is important for your health as well as for the health of your baby. Your diet before pregnancy and while you are pregnant should contain the vitamins and nutrients that your body will need to help your baby develop and grow the way he or she should. Practice healthy eating and take a multivitamin each and every day. Start this good habit before you become pregnant and continue eating healthy and taking a prenatal multivitamin throughout your pregnancy. If you need help choosing healthy foods or have questions about how to improve your diet for your future baby, ask a health professional at your doctor’s office or at a local clinic.
