Effects of soy XXXX consumption on bone structure and milk mineral concentration in a @entity35 model of lactation-associated @entity604 .

BACKGROUND: Like menopause, during complete lactation, circulating @entity172 concentrations are markedly reduced, resulting in amplified bone resorption. AIM OF STUDY: To investigate the effects of soy @entity6400 , common dietary components used to mitigate the @entity604 of menopause, on the @entity604 associated with lactation. METHODS: Lactating @entity35 were randomized to one of four diets supplemented with different levels of soy @entity6400 (0, 2, 4, 8 mg aglycone @entity3093 /g protein). Milk was collected from all dams between days 12 and 15 of lactation and was analyzed for @entity460 , @entity3151 and @entity670 concentrations. Serum and bones from half of the animals from each diet group were taken at weaning and from the remaining half at 4 weeks post-weaning. Bones underwent histomorphometric analysis and serum was used for @entity670 determinations. RESULTS: Serum @entity670 and milk concentrations reflected dietary @entity3093 dose. @entity3093 intake had no effect on any of the bone changes associated with lactation or recovery. Milk @entity460 and mineral concentrations were unaffected by dietary @entity6400 . CONCLUSIONS: Consumption of soy @entity6400 , in levels that can be readily attained through soy foods, have neither protective effects on bone nor deleterious effects on milk quality or quantity during lactation.
