TL;DR: Data indicate that the bioelectrical impedance technique is a reliable and valid approach for the estimation of human body composition and further validation of this method is recommended in subjects with abnormal body composition.

TL;DR: Plasma copper, RID Cp, and cytochrome oxidase in platelets and mononuclear cells were significantly affected by age, but superoxide dismutase (SOD) and in vitro 67Cu uptake by red blood cells did not differ.

TL;DR: Under controlled conditions, a high meat compared with a low meat diet for 8 wk did not affect calcium retention or biomarkers of bone metabolism in healthy postmenopausal women and calcium retention is not reduced when subjects consume a high protein diet from common dietary sources such as meat.

TL;DR: It is indicated that 0.8 g protein/kg body wt meets protein requirements in older women, and that high meat consumption increases zinc retention without compromising calcium status and may reduce indexes of iron status, in contrast with iron absorption results from studies with radiolabeled test meals.

TL;DR: In a controlled feeding study, the effects of substituting 25 g soy protein for meat on calcium retention and bone biomarkers were determined in postmenopausal women as discussed by the authors, and the results showed that the substitution of 25 g high isoflavonesoyprotein (SOY) for meat, in the presence of typical calcium intakes, did not improve orimpair calcium retention or indicator of bone and cardiovascular health.
