Final answer:
To ensure well-being during pregnancy, a diet rich in folic acid, iron, calcium, and vitamin D is crucial, along with prenatal care and avoidance of toxins. So, the correct answer includes all the options.
Step-by-step explanation:
To ensure Caitlin's well-being during pregnancy, it is essential that her diet includes critical nutrients such as folic acid, iron, calcium, and vitamin D. Folic acid, or vitamin B9, is recommended at a minimum intake of 400 µg/day to prevent neurological defects in the developing fetus, such as spina bifida.
Iron is crucial to prevent anemia and to help increase the blood's capacity to carry oxygen, which is vital for both the mother's and baby's health. Calcium is necessary for the development of a strong skeletal system in the growing fetus, and vitamin D ensures proper calcium absorption and bone growth.
During pregnancy, the mother's role includes providing essential nutrients and avoiding exposure to toxic substances like alcohol, especially during the first eight weeks when major organs are forming. A combination of a healthy diet and prenatal vitamin supplements is recommended for the best pregnancy outcome. Finally, regular prenatal care with health professionals is crucial to monitor the health of both mother and fetus and reduce the risk of complications.
