    Study Notes

    Pregnancy Nutrition

    • Prior to pregnancy: Optimal health and nutrition before conception are crucial for healthy fetal development. A healthy weight, physical activity, and balanced diet influence fertility and maternal health.
    • Healthy body weight: Preconception weight significantly impacts fetal growth and maternal and infant health. Underweight women are at increased risk of low-birth weight babies, preterm births, and developmental disabilities. Overweight or obese women face risks for maternal complications (hypertension, gestational diabetes), delivery complications, and infant complications (neural tube defects).
    • Physical activity: Regular physical activity before pregnancy benefits both mother and baby.
    • Adequate and balanced diet: A balanced diet is crucial for both the mother and the baby during pregnancy. Potential deficiencies must be accounted for and addressed.

    Fetal Development & Critical Periods

    • Critical periods: Fetal development has critical periods where it is most susceptible to nutritional influences. The embryonic period is especially vulnerable.
    • Folate: Crucial for protein metabolism, DNA synthesis, and prevention of neural tube defects. Adequate intake, preferably through supplementation throughout the first trimester, is critical.
    • Fetal programming: Maternal nutrients can affect gene expression in the fetus, influencing long-term health outcomes potentially.

    Nutrition During Pregnancy

    • Macronutrients: Increased energy needs to support maternal changes and fetal development. Protein requirements increase, but carbohydrate quality (complex carbohydrates) is more important for brain development.
    • Cell growth and blood production: Folate, vitamin B12, vitamin C, vitamin A, iron, zinc, and iodine needs increase during pregnancy, all crucial for rapid cell division and blood production.
    • Bone development: Vitamin D and calcium are critical for bone development; calcium absorption is aided by elevated vitamin D levels.

    Nutrition After Pregnancy and Lactation

    • Postpartum: The body needs to re-establish energy stores and recover, especially after childbirth.
    • Lactation: Energy and nutrient needs increase for milk production.
    • Nutrients during lactation: Energy, protein, carbohydrates, and lipids remain important, but folate, vitamin B12, vitamin C, calcium, and iron become more important as they may be lost or required for milk production.
    • Infant nutrition: Infants, especially during the first six months, have high energy and nutrient needs for rapid growth. Breast milk provides optimal support to ensure adequate nutrition during the first six months.

    Childhood Nutrition

    • Energy and Macronutrients: Energy needs are age-dependent and change over time. Carbohydrates remain important as fuel for cells. Fibre increases with age. Protein needs gradually increase. Lipids are important to neural development.
    • Vitamins and minerals: Fruit and vegetables provide vitamins A, C, and E. Calcium needs are supported by diary and alternatives. Iron deficiency anemia is common and requires attention.
    • Cow's milk: Cow's milk should typically not be introduced before one year of age due to its low iron content, higher calcium content, and potential impact on iron absorption, and impact on digestive and kidney health.
    • Malnutrition in childhood: Malnutrition during this period negatively impacts growth, physical, and cognitive development.

    Adolescent Nutrition

    • Energy needs: Energy requirements are high due to rapid growth and development. Macronutrient needs (with special care for iron, vitamin A, calcium, vitamin D) are similar to adults.
    • Bone health: Calcium and vitamin D are critical for bone growth and development during adolescence, and this is often targeted as part of youth developmental health.
    • Physical activity: Sufficient physical activity is crucial.

    Nutrition in Older Adults

    • Physiological changes: Aging is associated with declines in immune function, changes in organ systems, and body composition changes (e.g. muscle and bone loss).

    • Nutritional needs: Energy needs decrease moderately with age as does activity. Protein needs remain steady, aiding in immune response and against sarcopenia. Vitamins and minerals are as important but concerns about factors negatively affecting absorption in aging adults are important, particularly B12.

    • Longevity and healthy aging: Healthy aging can be achieved through proper habits (sleep, weight management, physical activity), but also focuses on balanced nutrition to maintain health.
