Learning Objectives
 Explain why a nutritionally adequate diet is
important long before a pregnancy is
established.
 Identify the special nutritional needs of a
pregnant teenager as compared to a

alcoholic beverage intake is safe or
advisable during pregnancy.”
Learning Objectives
 Describe the impacts of gestational
diabetes and preeclampsia on the health of
a mother and her unborn child.
 Discuss the nutrition and health benefits of
breastfeeding to both the mother and the
child.

Preparing for Pregnancy
 Healthy placenta and other organs

could affect her grandchildren and children
The Placenta

Development
