Fat is critical for this; therefore inadequate intake during pregnancy may impair fetal brain development.
Brain growth
Inadequate intake of vitamin C during pregnancy will adversely affect this and may result in preterm birth.
Collagen synthesis
Inadequate intake of zinc during pregnancy will adversely affect this and may lead to fetal malformations.
DNA, RNA, and protein synthesis
This may occur in the uterus due to malnutrition during pregnancy.
Decreased vasculature
The uterus, which carries this, may experience decreased vasculature if malnutrition occurs during pregnancy.
Developing fetus
Critical for brain growth and eye development, inadequate intake during pregnancy may impair fetal brain development.

Inadequate intake of fat during pregnancy may impair this.
Fetal brain development
Jana is a 24-year-old woman who recently got married. She and her husband would like to start a family within the first year of their marriage. Jana wanted to make sure she looked good for her wedding and has therefore been following the Atkins Diet strictly for the past year, eating primarily chicken, fish, and red meat.

Preterm birth
Lori is a vegan who believes she gets all the nutrients she needs from her diet. She has never taken supplements, even when she was pregnant. Her baby, Mason, was born full-term, but with a small portion of his spinal cord protruding through his vertebrae, resulting in partial paralysis of his legs. This neural tube defect, called _______ , may have been caused by Lori's insufficient intake of ________ during pregnancy. This micronutrient is necessary for regenerating the active form of _______ .
Spina bifida, vitamin B12, folate
Malnutrition during pregnancy may result in decreased vasculature of this organ that holds the developing fetus.
Uterus
Necessary for collagen synthesis, inadequate intake during pregnancy may result in preterm birth.
Vitamin C
Critical in DNA, RNA, and protein synthesis, zinc inadequacy during pregnancy may lead to this.
