CHO requirements ______ during lactation | increases |
Increases in CHO requirements are seen during lactation because.. | there is a higher respiratory quotient and rates of CHO utilization |
The increase in glucose utilization is under _____ sensitivity | hormonal |
Increased sensitivity to ____ under hormonal influence of lactation of _______ to _____ | - insulin - mammary gland - glucose |
The increased sensitivity may be a protective mechanism for | insulin resistance |
insulin resistance is protected by increased insulin sensitivity because.. | the sensitivity on the mammary gland are much increased relative to adipose tissue and other tissues, therefore the mammary gland gets more of the glucose load |
insulin secretion at the pancreatic level is increased by | prolactin |
The level of sensitivity of the receptors at the _______ level and the ability to secrete insulin at the _______ level are enhanced | - mammary gland - pancreatic |
the lactose content of human milk is approximately | 74 g/L |
lactose concentration changes __________ during the nursing period | very little |
precursors for lactose synthesis are ______ and must be _____ | - glucose - increased |
Increase in CHO must be obtained from | ingested CHO or an increased supply of AA to prevent utilization of lactating woman's endogenous proteins for glucose production |
Glycerol derived from endogenous or exogenous fat may contribute to ____ production of ______ through ________ | - increased - glucose - gluconeogenesis |
amount of fat that can be oxidized daily greatly _____ the contribution of glycerol to _____ production and thus _____ formation | - limits - glucose - lactose |
To lose weight during pregnancy, _____ have to be considered and ensured that they are met during this period | macronutrients |
Inadequate ____ or ____ can lead to alterations in body composition | - CHO - protein |
During lactation, dietary regimen should be | a mild caloric restriction, in concert with an exercise program |
True or False: fibre intake reducing effects on the risk of CHD in lactating is different from nonpregnant | False, there is no evidence of this |
Fibre requirements in lactating are ________ compared to non-pregnant, non-lactating | increased |
True or False: Thiamin is transferred to daily milk and therefore additional thiamin is needed | True |
Women who are breastfeeding older infants may need slightly less thiamin because | there is less milk production since the infants are also eating solid food |
True or False: Riboflavin is transferred to the mother's milk each day and therefore additional riboflavin is needed | True |
Women who are breastfeeding older infants need ________ riboflavin, in proportion to lower milk volume production | slightly less |
The use of riboflavin for ilk production is assumed to be ____% efficient | 70% |
those breastfeeding more than one infant may need _____ riboflavin | increased |
True or False: Niacin is secreted into the mothers milk and therefore additional amounts are needed | True |
Women breastfeeding more than one infant need ______ niacin | additional |
Converting tryptophan to niacin may contribute to | the large apparent variation in niacin requirements |
Biotin is ______ during lactational period | increased |
True or False: Distinctions are made for biotin requirements for the stage of lactation | False, no distinction is made |
Pantothenic acid content of milk _____ with intake of vitamin | increases |
Blood pantothenic acid levels are _____ in lactating women at ______ postpartum and ______ postpartum | - lower - 6 weeks - 3 months |
True or False: pantothenic acid intakes are inadequate to support function during lactation | False, there is no evidence of this |
Pantothenic acid requirements are ______ during lactation | increased |
