Nutrient Requirements During Lactation Flashcards
is the protein content in human milk influenced by diet or body composition?
neither. if there’s insufficient intake, the body will take some from the mother’s muscles.
does the process of lactation affect protein turnover (protein lost on a daily basis)?
no
on average, how much more protein is needed during the first 6 months?
21 more grams per day
EAR of protein during lactation?
1.05 g/kg/day
RDA of protein during lactation?
1.24 g/kg/d
AI for N-6 (linoleic acid)?
13 g/d
AI for N-3 Fatty acid? what’s it based on?
1.3 g/d
based on median intakes
does CHO requirement change during lactation?
yes, we see a higher respiratory quotient (RQ). the mammary gland prefers to use glucose to supply lactose.
what is the EAR for CHO based on?
there’s 60 g CHO needed to supply the CHO equivalents secreted in breast milk
EAR of carbohydrate during lactation?
160 g/day
RDA of CHO during lactation?
210 g/day
AI for dietary fiber
14 g/1000 kcal x median energy intake
Thiamin EAR during lactation?
1.2 mg/d
what is the thiamin requirement based on?
loss of thiamin that’s transferred into the breastmilk, and increased energy needs
RDA of thiamin during lactation?
1.4 mg/d
EAR for riboflavin
1.3 mg/d
what is the riboflavin requirement based on?
0.3 mg/d is transferred to milk. only 70% of what is consumed in the diet is able to make it into the milk so you have to eat more.
RDA for riboflavin?
1.6 mg/d
what is the requirement for niacin based on?
secretion in milk and energy required for lactation
EAR for niacin?
13 mg/d
RDA for niacin?
17 mg/d
what is the requirement for biotin based on?
secretion
AI for biotin?
35 ug/d
what is the requirement for pantothenic acid based on?
secretion in milk.
note after 6 weeks post partum there is a drop in this blood concentration
AI for pantothenic acid?
7 mg/d
what is the requirement for b6 based on?
energy required for lactation and some secretion
EAR for vit b6?
1.7 mg/d
RDA for vit b6?
2.0 mg/d
what is the requirement for folate based on?
secretion in milk and bioavailability
what is the EAR for folate?
450 ug/day of DFE
what is the RDA for folate?
500 ug/d
what is the requirement for vit b12 based on?
amount secreted in milk (there’s more secreted in the first 6 months than the last six months)
EAR for vit B12?
2.4 ug/day
RDA for vit B12?
2.8 ug/d
what is the choline requirement based on?
secretion in milk
what is the AI for choline?
550 mg/d
what is the vit c requirement based on?
secretion in milk
what is the EAR for vit c?
100 mg/d
what is the RDA for vit c?
120 mg/d
what is the requirement for vit a based on?
secretion in milk
what is the EAR for vit A?
900 ug RAE/d
what is the RDA for vit A?
1300 ug RAE/d
what is the requirement for vit d based on?
there’s no evidence that an increase in vit D is necessary. there’s a small quantity secreted in the breast milk
what is the RDA for vit D?
15 ug/d
what is the requirement for vit E based on
secretion in milk
what is the EAR for vit E?
16 mg/d
what is the RDA for vit E?
19 mg/d
