Nutritional Requirements During Pregnancy

  • Increase in Calories:

    • First Trimester: No added calories necessary.

    • Second Trimester: +340 calories per day.

    • Third Trimester: +452 calories per day.

Additional Supplements

  • Folic Acid: Vital for fetal development, reduces the risk of neural tube defects.

  • Iron: Supports increased blood volume and prevents anemia.

  • Calcium: Essential for fetal bone development.

  • Sodium/Water: Necessary for fluid balance and preventing dehydration.

Common Factors Influencing Nutritional Status and Choices

  • Various social, emotional, and physiological factors can affect a woman’s nutritional status and dietary choices during pregnancy.

  • Examples of risk factors for inappropriate nutrition include:

    • Pre-existing medical conditions (e.g., diabetes, anemia).

    • Cultural beliefs and practices regarding food.

    • Socioeconomic status affecting food access.

    • Personal preferences and aversions.

Food Precautions During Pregnancy

  • Foods to Avoid:

    • Shark, swordfish, king mackerel, or tilefish due to high mercury content.

    • Avoid raw or undercooked fish, meat, poultry, or eggs to prevent foodborne illness.

    • Luncheon meats and hot dogs should be consumed only when heated until steaming hot.

    • Soft cheeses or unpasteurized milk to avoid listeria contamination.

    • Refrigerated pate or meat spreads.

What Is Pica?

  • Pica is a psychological condition wherein individuals crave and consume non-food items such as:

    • Cigarette butts

    • Dirt

    • Paint

    • Soap

  • This condition can be indicative of mineral deficiencies or emotional stress.

Nutrition After Birth

  • Non-Lactating Mothers:

    • Dietary return to pre-pregnancy norms is recommended.

    • Expected weight loss dynamics are:

    • Birth: loss of 12 lb

    • At 2 weeks post-birth: additional 9 lb loss

    • By 6 months: a total of 5.5 lb loss, should retain only 3 lb of pregnancy weight.

  • Breastfeeding Mothers:

    • Additional caloric intake of:

    • Up to 6 months: +500 calories per day.

    • 6 months to 1 year: +400 calories per day.

    • Dieting is generally discouraged until at least 3 months postpartum.

    • Caffeine: Should be restricted to 2 cups per day.

    • Alcohol: Should not be consumed until at least 2 hours after feeding to prevent harm to the infant.

Comparison of Nutritional Needs

  • Nutritional needs differ significantly between breastfeeding and non-breastfeeding mothers, primarily regarding caloric intake, dietary quality, and timing of weight loss efforts.

  • Further considerations include the necessity for specific vitamins and minerals that support lactation and infant health.
