ABSTRACT
As a result of iron and zinc generally coexist in meals, marginal iron and zinc standing are normally related, significantly in growing international locations (4,5) wherein diets normally present restricted quantities of meat, a supply of extremely obtainable iron and zinc. Due to this fact, the aim of our research 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 ladies 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
Information had 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 take a look at inside the corresponding group. Variations had been thought-about important at P < 0.05.
RESULTS
Within the zinc-supplemented ladies, zinc absorption decreased (P < 0.001) after supplementation to about half the worth at baseline, whereas iron absorption virtually doubled (P < 0.01). The chances of iron and zinc absorption measured at baseline and after the 6 wk supplementation with both zinc or iron had been low (Desk 3) as beforehand noticed from legumes as a result of presence of a number of inhibitory elements, equivalent to phytate (18,19). Within the iron-supplemented ladies, zinc absorption didn't change, whereas iron absorption decreased to lower than half of the preliminary worth (P < 0.01).
DISCUSSION
The authors admire the cooperation of the ladies who participated within the research.
