What to know about nutrition during pregnancy

During pregnancy, the body's nutritional needs undergo significant changes to accommodate the growth of the baby and to support the mother's health. Adequate intake of various nutrients like folic acid, iron, calcium, and omega-3 fatty acids becomes crucial during this time. These nutrients play vital roles in the formation of the baby's organs and tissues, as well as in preventing birth defects and ensuring the overall health of the mother.

Individual dietary needs may vary during pregnancy due to factors like pre-existing health conditions, allergies, or cultural preferences. Consulting a St. Luke’s Health OB/GYN can help tailor a suitable and personalized nutrition plan for a healthy pregnancy. Ultimately, prioritizing nutrition during pregnancy significantly contributes to the well-being of both the mother and the baby.

What nutrient requirements do you need to watch during pregnancy?

During pregnancy, several key nutrients require attention to support the health and development of both the mother and the growing baby. These include:

  • Folic acid: Crucial for neural tube development in the early stages of pregnancy, reducing the risk of neural tube defects like spina bifida.

  • Iron: Essential for the production of red blood cells to prevent anemia in both the mother and baby. The body's need for iron increases during pregnancy to support the growing blood supply.

  • Calcium: Vital for the development of the baby's bones and teeth. Adequate calcium intake also supports the mother's bone health.

  • Omega-3 fatty acids: Important for the development of the baby's brain and eyes. Omega-3s like DHA are particularly crucial during the later stages of pregnancy.

  • Protein: Necessary for the growth of the baby's cells, including the brain, muscles, and organs.

  • Vitamin D: Essential for calcium absorption and bone development in both the mother and the baby.

  • Iodine: Critical for the development of the baby's brain and nervous system.

  • Vitamin B12: Important for the formation of red blood cells and the development of the nervous system.

  • Vitamin C: Helps with iron absorption and supports the body's immune system.

  • Zinc: Essential for normal growth and development during pregnancy.


Consult a St. Luke’s Health OB/GYN to determine the best diet plan and before starting any supplements for your individual needs.

Importance of prenatal vitamins

Prenatal vitamins play a crucial role in supporting the health of both the expectant mother and the developing baby during pregnancy. These specialized supplements are designed to provide essential nutrients that may be challenging to obtain through diet alone. Here's why they're important:

  • Nutrient support: Prenatal vitamins ensure that the mother receives adequate amounts of key nutrients like folic acid, iron, calcium, and various vitamins and minerals crucial for the baby's growth and development.

  • Filling nutritional gaps: Even with a well-balanced diet, pregnant women might not consistently meet their increased nutritional needs. Prenatal vitamins help bridge these gaps to ensure a steady supply of essential nutrients.

  • Preventing birth defects: Folic acid in prenatal vitamins significantly reduces the risk of neural tube defects such as spina bifida and anencephaly, supporting proper brain and spinal cord development in the baby.

  • Red blood cell production: Iron in prenatal vitamins helps prevent iron-deficiency anemia, a common condition during pregnancy. Anemia can lead to fatigue, weakness, and complications for both the mother and baby.

  • Bone development: Calcium and vitamin D in prenatal vitamins support the baby's bone development, helping to prevent issues like osteoporosis in the mother.

  • Healthy pregnancy: These supplements contribute to a healthy pregnancy by supporting the immune system, energy levels, and overall well-being of the mother.

  • Compensation for food aversions or restrictions: Some pregnant women experience food aversions or have dietary restrictions due to medical reasons. Prenatal vitamins ensure essential nutrients are still obtained even if certain foods cannot be consumed.

  • Postpartum health: Continuing prenatal vitamins during breastfeeding can support the mother's recovery and provide nutrients for both her and the nursing baby.
