Question Answer
The AI for lactation is _____ compared to that of non-lactating increased
True or False: maternal dietary intervention with n-6 fatty acids effects growth and development in the infact False, there is no evidence of this
AI of n-6 fatty acids is based on the median linoleic acid intake of lactating women where a deficiency is basically nonexistent
n-3 fatty acids secreted in milk during lactation is met by n-3 fatty acids from maternal tissues or through dietary intake
lactating women present ______ plasma and RBC lipid DHA levels lower
Lower plasma DHA may be due to - inadequate n-3 fatty acid intakes - changes in maternal DHA levels are normal physiological responses to the changes in endocrine status, lipoprotein and lipid metabolism, or nutrient transfer that accompany pregnancy and lactation
DHA levels in both the mother and the newborn infant can be increased by supplementation with fish oil during pregnancy
DHA supplementation during lactation increases the concentration of DHA in the mother's milk and in the infant's blood
True or False: increasing intakes of DHA in pregnant and lactating women consuming diets that meet n-6 and n-3 requirements have no physiologically significant benefit to the infant True, there is no evidence available to state otherwise
Lipoprotein lipase activity is _____ increased
Lipoprotein lipase increase is induced on the level of the _________ under ______ stimulus - mammary tissue - prolactin
Increases in lipoprotein lipase mobilize.. Fat reserves to come into the mother's mammary gland as opposed to in fat stores
AI for lactation is _____ from that in nonlactating, but _____ from that in pregnancy - increased - decreased
______ contributes towards reversing n-3 fatty acid deficiency small amounts of EPA and DHA
lower n-3 and n-6 fatty acids are seen because.. there is less fish consumption during pregnancy
