(breast) where milk is synthesized and secreted for infant - ANS-mammary gland
1. hyperplasia (up cell multiplication)
2. hyperplasia + hypertrophy
3. hypertrophy (up cell growth)
4. maturation (stabilization of cell # + size --> anything that disrupts multiplication or eventual
size has unfavorable outcomes later) - ANS-four critical periods of growth and development
10 days after birth, milk composition is stable - ANS-lactogenesis 3
10-12 feedings/day. stomach empties ~1 1/2 hours - ANS-feeding frequency
2-5 days after birth, increased blood flow to breast, milk "comes in" + changes to mature milk -
ANS-lactogenesis 2
38-41 weeks (42 weeks likely induce, 37 or less = preterm, poor health) - ANS-optimal term
length
3rd trimester, milk formation begins - ANS-lactogenesis 1
40 weeks after last menstrual period - ANS-pregnancy term
66% of infant deaths caused by LBW - ANS-low birth weight issues
actual production of offspring - ANS-fertility
another highly sensitive period where nutrition and lifestyle of the mother matters -
ANS-periconceptional period
anovulation, amenorrhea, delayed conception, reduced response to fertility treatment -
ANS-obesity in females
appropriate for gestational age - ANS-AGA
beef, yogurt, pumpkin seeds, chickpeas - ANS-foods high in zinc
breasts overfilled with milk, supply-and-demand process not established yet, milk abundant -->
nurse frequently, cold compress to reduce discomfort - ANS-engorgement
builds the foundation of a child's ability to grow, learn and thrive - ANS-first 1000 days
, cell growth and differentiation - ANS-vitamin A
chemicals in soy with properties similar to estrogen, high intake may decrease sperm count and
fertility - ANS-isoflavones
close to exponential, rapid weight gain in third trimester (stores fat and glycogen) - ANS-fetal
growth
decreases fertility, critical body fat level needed for fertility (males - reduces sperm health),
decreases estrogen productions - ANS-undernutrition
diminish health and make it harder to reach full developmental potential - ANS-risk factors
disproportionately small for gestational age <10% w/ normal head circumference + length -->
post birth complications + increased risk for disease later - ANS-dSGA
do not restrict completely, limit processed foods - ANS-sodium
don't need to cut out soy but amount eaten should be moderate and minimize processed soy
products as they are more concentrated with isoflavones - ANS-soy foods affect on fertility
essential for cell division and DNA replication during fetal growth - ANS-vitamin B
essential oils in foods such as garlic and spices can pass into breastmilk + occasionally infant
may object to their presence - ANS-sensory qualities of BM
fatty acids DHA + trans fat, vitamin D, water soluble vitamins - ANS-nutrient levels that reflect
maternal diet
first 2 months - ANS-period of most rapid cell growth
first half, builds capacity to deliver bllod, oxygen + nutrients to fetus. fat + glycogen
accumulation, cardiac output increases --> exhaustion, appetite increases - ANS-anabolic
phase
first milk secreted during lactogenesis 2. high in proteins and vitamin A (beta carotene ~ yellow
color), lower in lactose. primes gut for all the nutrients to come - ANS-colostrum
fish, healthy diet + exercise - ANS-preterm protectives
foremilk: more water and carbs, lot of lactose
hindmilk: more protein and fats
