Zinc absorption and intestinal losses of endogenous zinc in young Chinese women with marginal zinc intakes.
The objective of this study was to determine fractional absorption of exogenous zinc and intestinal excretion of endogenous zinc in women of childbearing age whose habitual dietary zinc intake was marginal. The target population (L group) comprised residents of a remote farming village in northeast China and the control subjects (M group) were residents of Beijing. Mean (+/-SE) calculated dieta...
متن کاملINTESTINAL ZINC ABSORPTION IN DESFERROXAMINE-TREATED RATS
Desferroxamine (Desferal) is used tochelate iron in thalassemia, a disease of very high prevalence in various parts of lran. We have investigated intestinal zinc absorption in Desferal-treated rats which, in pilot experiments, showed low serum levels of both iron and zinc. Intraperitoneal administration of ten 0.5 g doses of Desferal (one injection every other day) to male rats produced sev...
متن کاملZinc absorption adapts to zinc supplementation in postmenopausal women.
OBJECTIVE To determine if human Zn absorption adapts to chronic high Zn intakes. METHODS Zn absorption was measured at 0, 8, and 16 wk in healthy postmenopausal women who consumed controlled diets with approximately 5 mg Zn from food, supplemented to 14 (n = 6), 32 (n = 3), or 47 (n = 3) mg Zn/d for 22 wk. Zn absorption for 1 day was determined by (65)Zn-labeling of meals and whole body scint...
متن کاملZinc supplementation reduces fractional zinc absorption in young and elderly korean women.
BACKGROUND Adjustments in zinc losses and absorption are thought to maintain zinc homeostasis with changes in intake, but the capacity to make these adjustments appears to be affected by aging. Zinc status of the individual may also influence adjustments in fractional zinc absorption. OBJECTIVE The purpose of this study was to compare the effects of changes in zinc status due to zinc suppleme...
متن کاملAssociations between Dietary Iron and Zinc Intakes, and between Biochemical Iron and Zinc Status in Women
Iron and zinc are found in similar foods and absorption of both may be affected by food compounds, thus biochemical iron and zinc status may be related. This cross-sectional study aimed to: (1) describe dietary intakes and biochemical status of iron and zinc; (2) investigate associations between dietary iron and zinc intakes; and (3) investigate associations between biochemical iron and zinc st...
