Adaptation in iron absorption: iron supplementation reduces nonheme-iron but not heme-iron absorption from food.
BACKGROUND Results of cross-sectional studies suggest that in healthy people, iron absorption adapts to meet physiologic needs and stabilize iron stores, but this has not been adequately tested in longitudinal studies. OBJECTIVE We tested whether heme- and nonheme-iron absorption decrease in response to increased iron intake and whether iron stores reach a steady state. DESIGN In a randomiz...
متن کاملA complete diet-based algorithm for predicting nonheme iron absorption in adults.
Many algorithms have been developed in the past few decades to estimate nonheme iron absorption from the diet based on single meal absorption studies. Yet single meal studies exaggerate the effect of diet and other factors on absorption. Here, we propose a new algorithm based on complete diets for estimating nonheme iron absorption. We used data from 4 complete diet studies each with 12-14 part...
متن کاملEffect of ascorbic acid intake on nonheme-iron absorption from a complete diet.
BACKGROUND Ascorbic acid has a pronounced enhancing effect on the absorption of dietary nonheme iron when assessed by feeding single meals to fasting subjects. This contrasts with the negligible effect on iron balance of long-term supplementation with vitamin C. OBJECTIVE Our goal was to examine the effect of vitamin C on nonheme-iron absorption from a complete diet rather than from single me...
متن کاملRegular Consumption of a High-Phytate Diet Reduces the Inhibitory Effect of Phytate on Nonheme-Iron Absorption in Women with Suboptimal Iron Stores.
BACKGROUND High phytate (HP) consumption is a concern in developing countries because of the high prevalence of iron deficiency in these countries. OBJECTIVE We investigated whether habitual consumption of an HP diet reduces the inhibitory effect of phytate on nonheme-iron absorption. METHODS Thirty-two nonanemic females, 18-35 y of age, with normal body mass index but with suboptimal iron ...
متن کاملInfluences on meat consumption in Australia.
In a study of influences on meat consumption, over 700 South Australians answered questions on frequency of meat consumption, beliefs about meat and nutrition, perceived difficulties with and benefits of vegetarian diets, personal values, number of vegetarian significant others, use in and trust of health/nutrition/food information sources, and demography. Perceived difficulties with vegetarian...
