breastmilk composition -ANSWERS-human milk changes continually, makes it
impossible to obtain a single representative sample of milk
preterm milk -ANSWERS-appears to have a different composition for the first 5-7
weeks after delivery independent of gestational age at delivery
- appears to be higher in protein, fat, and electrolytes than term milk
- if baby is SGA, LGA, or AGA, does not make a difference in milk composition
after 1 year of lactation -ANSWERS-has significantly increased fat and energy
contents
fore vs hind milk -ANSWERS-foremilk is milk at the beginning of a feed, hindmilk is
at the end of a feed
- used to think that hindmilk contained more fat content but it is more complex
than originally described
- foremilk does not mean "low fat" and hindmilk is not always highest in fat
- sometimes foremilk and hindmilk have equal amounts of fat and we should not
give mothers tules based on the ideas of fore and hindmilk
breastmilk composition changes -ANSWERS-- over the course of lactation
- within the day
- within a feeding
,- between feedings
is also changes by the way it is taken
babyled feeding -ANSWERS-"the breast-fed baby can regulate his fat intake
quickly and thus mothers should be encouraged to practice baby-led feeding"
maximum fat levels -ANSWERS-obtained 30 mins post-feed
- mothers of male infants seem to produce milk that has 25% greater energy
content than mothers of female infants
milk composition, milk action -ANSWERS-milk composition is complex, milk action
is redundant
- milk is more than nutrition, bioavailability of nutrients is higher in human milk
than in other foods or supplements
less diarrhea -ANSWERS-most readily acknowledged advantage od breastfeeding,
ebf makes the biggest difference in rates and severity
- 86% of diarrhea-associated infant deaths occurred among LBW infants
- if breastfed baby does get diarrhea, keeping breastfeeding makes a difference in
maintaining the microbiota
mechanisms by which ebf protects from diarrhea -ANSWERS-1. ph of gut
2. low iron in gut
3. presence of bifidus factor
4. presence of hormones
, 5. antibodies such as SIgA
6. white blood cells
7. cell wall disrupters
8. B12 binding factor
9. lactoferrin
10. antimicrobial activity boosters
11. mucosal wall protectors
12. microbes
13. absence of exposure to contaminants
14. antibodies
15. synergistic effect
diarrhea mechanisms 1 - ph of the gut -ANSWERS-breastfed babies' gut is more
acidic while formula-fed babies' guts are more neutral/basic
gut bacterial colonies (the microbiome) of mixed fed babies are similar to
exclusively formula fed babies
diarrhea mechanisms 2 - low iron in the gut -ANSWERS-relatively low iron content
in human milk
diarrhea mechanisms 3 - presence of bifidus factor -ANSWERS-promotes
intestinal presence of lactobacillus bifidus that maintain the low pH and crowd
out pathogenic organisms
