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.
Vitamin C: necessary for collagen production; 85 mg/day recommended during pregnancy.
Vitamin A: needs increase by 10% during pregnancy; supplementation is not recommended due to toxicity risks.
Vitamin D: adequate intake should be maintained; supplementation may be necessary depending on sunlight exposure and milk consumption.
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:
- Alcohol: Can be harmful to fetal development.
- Tobacco: Can harm fetal development.
- Toxic Agents: Including environmental pollutants.
