Why are fats important for breast milk?
Essential to brain development
Absorption of fat soluble vitamins
LCPs support nervous system development
How are vitamins and minerals acquire on formula?
Vitamins and minerals added to poweder
What do transfer factors do?
Enable effective absorption of nutrients in milk
Give an example of a transfer factor and its uses.
Lactoferrin
Assists in absorption of iron
Bactericidal
What does IgA do?
Protective coating for baby’s gut to prevent entry of pathogenic bacteria and enteroviruses and protect against inflammation
What is an indication of a stronger immune system in breast fed babies?
Higher IL-7 levels Larger thymus (Organ central to immune system)
What is colostrum?

What are some non-nutritional beneficial factors in breast milk?
Maternal antibodies and hormones kickstart baby’s endocrine system
Metabolites stimulate enzyme release
How do babies pick up familial microbiomes?
As they pass through vagina at birth
Through mother’s milk in postnatal period and beyond
How may the bacterial transfer shortcomings of a c section be compensated?
Prolonged skin-to-skin contact
Breastfeeding v important
How does the broncho-mammary pathway work?
Pathogens inhaled
Antibodies produced and sent to breasts
Antibodies incorporated into breast milk
Baby’s immune system updated
How does the entero-mammary pathway work?
Pathogen ingested
Antibodies produced and sent to breasts
Antibodies incorporated into breast milk
Baby’s immune system updated
What are the stages of lactation?
Lactogenesis 1, 2, and 3
Describe lactogenesis 1.
