ABSTRACT
As a result of iron and zinc generally coexist in meals, marginal iron and zinc standing are often related, significantly in creating nations (4,5) by which diets often present restricted quantities of meat, a supply of extremely out there iron and zinc. Due to this fact, the aim of our examine was to judge the impact of zinc or iron supplementation taken at bedtime with out meals on zinc and iron metabolism and absorption in younger girls with low iron reserves. As a result of zinc and iron work together throughout absorption and, probably additionally throughout metabolism (7,8), supplementation of solely one of many two might have an effect on the standing of the opposite nutrient.
SUBJECTS AND METHODS
Knowledge have been examined for normality and log-transformed for plasma ferritin, plasma transferrin saturation, EZP and iron absorption earlier than statistical analyses. The impact of zinc or iron supplementation was investigated by paired t check inside the corresponding group. Variations have been thought of important at P < 0.05.
RESULTS
Within the zinc-supplemented girls, zinc absorption decreased (P < 0.001) after supplementation to about half the worth at baseline, whereas iron absorption virtually doubled (P < 0.01). The odds of iron and zinc absorption measured at baseline and after the 6 wk supplementation with both zinc or iron have been low (Desk 3) as beforehand noticed from legumes because of the presence of a number of inhibitory components, similar to phytate (18,19). Within the iron-supplemented girls, zinc absorption didn't change, whereas iron absorption decreased to lower than half of the preliminary worth (P < 0.01).
DISCUSSION
The authors respect the cooperation of the ladies who participated within the examine.
