Explain how breast milk is formed in the mammary glands and the physiology of breast milk
Include two 2030 National Health Goals related to newborn nutrition to support breast feeding as the best choice. See the links below:

Discuss the advantages of breastfeeding related to immunities transferred to the newborn
Describe three additional benefits of breast feeding with supporting rationales
Breastfeeding Trifold
Full Answer Section
- Estrogen and Progesterone: During pregnancy, estrogen and progesterone stimulate the growth of milk ducts and prepare the mammary glands for lactation.
- Prolactin: After birth, with the decline of placental hormones, prolactin takes center stage. It signals the alveoli (milk-producing sacs) to begin milk production.
- Oxytocin: This "love hormone" is released during breastfeeding. It triggers the contraction of myoepithelial cells surrounding the alveoli, propelling milk towards the nipple for easy feeding.
- Carbohydrates: Lactose, the primary sugar in breast milk, provides energy for growth and brain development.
- Fats: Provide essential fatty acids for brain and nervous system development, and fat-soluble vitamins (A, D, E, and K).
- Proteins: Whey protein promotes growth and development, while lactoferrin helps fight infections.
- Vitamins and Minerals: Breast milk provides a readily absorbable source of vitamins and minerals crucial for infant health.
- Antibodies: Breast milk is a treasure trove of antibodies passed from mother to baby, boosting the infant's immune system and protecting them from infections.
- Healthy People 2030 - MICH-15: Increase the proportion of infants who are breastfed exclusively through 6 months of age to 42.4%.
- Healthy People 2030 - MICH-16: Increase the proportion of infants who are breastfed at 1 year to 54.1%.
- Immunoglobulins (IgA): This antibody protects the baby's gut lining from harmful pathogens.
- Leukocytes: White blood cells in breast milk help fight infections.
- Antimicrobial factors: Lysozyme and lactoferrin directly inhibit the growth of bacteria and viruses.
- Respiratory infections: Ear infections, pneumonia, and bronchitis.
- Gastrointestinal infections: Diarrhea and vomiting caused by viruses and bacteria.
- Atopic diseases: Eczema, asthma, and allergies.
- Optimal Nutrition: Breast milk is perfectly tailored to meet a baby's nutritional needs, promoting healthy weight gain and development. It's easily digestible and readily absorbed by the infant's immature digestive system.
- Emotional Bonding: The skin-to-skin contact during breastfeeding fosters a strong emotional bond between mother and baby, promoting emotional well-being and secure attachment.
- Long-Term Health Benefits: Breastfeeding has been linked to reduced risks of obesity, type 2 diabetes, and certain childhood cancers in babies. Mothers who breastfeed also experience health benefits like a reduced risk of breast and ovarian cancers and postpartum depression.
Sample Answer
Breast milk, a liquid gold for newborns, is a complex and dynamic substance specifically designed to meet the unique nutritional and immunological needs of an infant. Understanding its formation and benefits highlights its irreplaceable role in a baby's development.
Formation of Breast Milk: A Symphony of Hormones
The mammary glands, responsible for breast milk production, undergo dramatic changes during pregnancy and lactation (breastfeeding) driven by a symphony of hormones.
