    Study Notes

    Nutrition Before Conception

    • Folate deficiency during pregnancy can lead to neural tube defects.
    • Prenatal folate intake should be 400 µg daily.
    • Avoiding teratogens is crucial before conception (e.g., alcohol, drugs).
    • Maintaining a healthy BMI (19.8–26.0 kg/m2) is recommended.

    Nutrition During Pregnancy

    • Full-term pregnancy lasts 38-42 weeks.
    • First trimester is crucial for organ development and vulnerability to teratogens.
    • Second trimester involves continued organ development and fetal growth.
    • Third trimester is characterized by rapid growth, brain development, lung maturation, and weight gain.
    • Insufficient weight gain during pregnancy increases the risk of low birth weight.
    • Excessive weight gain is also associated with risks.
    • Dietary needs increase during pregnancy across all macronutrient and micronutrient categories.

    Macronutrients

    • Energy needs increase by 300-450 kcal/day during the second and third trimesters.
    • Protein requirement: 1.1 g/day/kg body weight.
    • Carbohydrate requirement: at least 175 g/day.
    • Fat intake percentage should remain consistent; limit saturated and trans fats.
    • DHA (docosahexaenoic acid) is an important omega-3 fatty acid for fetal development.

    Micronutrients

    • Folate: Crucial for cell division; deficiency associated with neural tube defects.
    • Vitamin B12: essential for folate activation; required at 2.6 ug/day during pregnancy.

    • Calcium: 1,000 mg/day recommended, absorption increases during pregnancy.
    • Zinc: essential for protein, DNA, and RNA synthesis; requirement increases 38% during pregnancy.
    • Iron: requirement increases by 50-80% due to increased red blood cell production; 27 mg/day recommended.
    • Sodium: no increase required during pregnancy, maintain 1,500 mg/day.
    • Iodine: requirement increases significantly; ensure adequate intake through iodized salt.

    Fluids During Pregnancy

    • Increased fluid needs: 3 L/day recommended.
    • Importance: blood volume increase, temperature regulation, amniotic fluid production, fluid retention prevention, and constipation reduction.
    • Morning sickness: nausea and vomiting common in early pregnancy.
    • Food cravings and aversions: often driven by hormonal fluctuations or cultural influences.
    • Gastroesophageal reflux (GER): common during pregnancy; managed by dietary adjustments and lifestyle modifications.
    • Constipation: frequent during pregnancy; can be reduced with dietary fiber and fluids.
    • Gestational diabetes: insulin resistance during pregnancy; requires careful blood glucose monitoring and management.
    • Preeclampsia: pregnancy-induced hypertension; potential complications can be fatal.

    Foodborne Illness

    • Pregnancy weakens the immune system, increasing susceptibility to foodborne illnesses.
    • Listeriosis: a serious infection particularly dangerous for pregnant women.

    Food Safety Recommendations

    • Avoid unpasteurized foods (milk, eggs, meat, fish, poultry, juices, sprouts).
    • Limit the consumption of large fish and canned albacore tuna due to mercury content.
    • Choose soft cheeses made with pasteurized milk.

    Adolescent Pregnancy

    • Nutritional needs are higher than adult women due to continued growth and development.

    Vegetarianism

    • Vegan women need to carefully monitor their intake of vitamin D, calcium, vitamin B6, vitamin B12, iron, and zinc.

    Exercise During Pregnancy

    • Benefits: reduced risk of gestational diabetes, preeclampsia, excessive weight gain, and preterm birth.
    • Improved overall health, mood, and physical endurance.

    Caffeine Consumption

    • Moderate intake (200-300 mg/day) is likely safe.
    • High intake may be associated with adverse pregnancy outcomes.

    Alcohol Consumption

    • Alcohol is a teratogen and should be avoided during pregnancy.
    • Fetal alcohol syndrome (FAS) is a serious condition resulting from alcohol exposure.

    Smoking and Drug Use

    • Risks: increased risk of miscarriage, stillbirth, preterm birth, and low birth weight.
    • Exposure to toxins harms fetal development.
    • Newborns may experience withdrawal symptoms due to drug exposure.

    Breastfeeding

    • Lactation is the production of breast milk stimulated by the hormone prolactin.
    • Colostrum is the first milk produced; highly nutritious and beneficial for newborns.
    • Milk let-down is triggered by oxytocin.
    • Increased caloric intake is required during breastfeeding.
    • Benefits of breastfeeding: high-quality nutrition, protection from infections, weight loss for the mother, and emotional bonding.

    Infant Nutrition

    • High energy needs: 40-50 kcal/lb/day.
    • Fat intake: 40-50% of calories.
    • Micronutrient needs: iron, vitamin D, zinc, fluoride, and iodine are of particular importance.
    • Introducing solid food: usually begins at 4-6 months of age.

    Supplements for Infants

    • Vitamin D: necessary for bone health, especially for exclusively breastfed infants.

    • Iron: needed to prevent iron-deficiency anemia as stores deplete around 6 months.

    • Fluoride: recommended if the water supply is not fluoridated.### Micronutrient Supplementation

    • Vitamin D: Infants may need supplementation due to limited sunlight exposure.

    • Iron: Iron stores deplete around six months of age, may need supplementation.

    • Fluoride: Supplementation is necessary for tooth development.

    • Vitamin B12: Vegan mothers may need to supplement their infants with Vitamin B12.

    • Water: Supplementation isn't typically required unless excessive fluid loss occurs (diarrhea, vomiting, fever, hot weather).

    Infant Formula

    • Federal government regulations dictate minimum and maximum standards for 29 nutrients in infant formulas.
    • Protein Source: Casein or whey from cow's milk.
    • Carbohydrate Source: Lactose and sucrose.
    • Fat Source: Vegetable oils or microbiologically produced lipids.
    • Specialized Formulas: Soy-based, predigested, and others for specific medical conditions are available.

    When to Introduce Solid Foods

    • Six Months: This is the ideal time to begin introducing solid foods.
    • Tongue Movement: At six months, infants have developed the ability to swallow.
    • Muscle Development: Infants can sit up independently by six months.
    • Digestive System & Kidneys: The digestive system and kidneys have matured by six months.
    • Food Allergies: Introducing solids later can increase the risk of food allergies.
    • Iron-Fortified Cereals: These are typically well tolerated by infants.

    Infant Nutrition Concerns

    • Choking Hazards: Avoid giving infants foods that could cause choking.
    • Corn Syrup & Honey: These should not be given to infants.
    • Goat's Milk: Not recommended for infants.
    • Cow's Milk: Not recommended for infants until after one year of age.
    • Salt & Sugar: Too much can be harmful to infants.
    • Allergies: Introduce solid foods one at a time to monitor for allergic reactions.
    • Dehydration: Extremely dangerous for infants, can be caused by diarrhea, vomiting, and inadequate fluid intake.
    • Colic: Uncontrollable crying that can last for hours, the cause is unknown.
    • Anemia: Infants are born with a six-month iron supply, iron supplementation may be necessary.
    • Nursing Bottle Syndrome: Frequent bottle use can lead to tooth decay and cavities.
    • Lead Poisoning: Toxic to infants, can hinder brain and nervous system development.

    The Fetal Environment

    • Fetal Origins Theory: The mother's prenatal nutrition can influence the infant's long-term risk of obesity and chronic diseases.

    Fetal Environmental Stressors

    • Famine: Exposure to famine in the first trimester can lead to increased obesity, coronary heart disease, abnormal lipid profiles, and metabolic syndrome.
    • Fetal Adaptation: In response to harmful elements, the fetus shifts hormones to promote energy storage, which impacts body organ size and function.
    • Nutrient Deficiencies: Maternal nutrient deficiencies can impact fetal development.
      • Calcium: Low intake can increase hypertension risk in offspring.
      • Folate: Low intake is linked to neural tube defects and atherosclerosis.
      • Zinc: Deficiencies can lead to later-life disorders like diabetes and atherosclerosis.
    • Dietary Excesses: Maternal dietary excesses increase the risk of health problems in offspring.
      • Obesity: Can affect fetal brain "programming" resulting in lifelong health consequences.
      • Diabetes: Can increase the risk of infant type 2 diabetes, overweight, and metabolic syndrome.
    • Fetal Exposure to:
