摘要

Fe deficiency is the number one nutritional disorder in the world and is quite common in Pakistan. Fe deficiency anaemia may result from a low dietary intake, inadequate intestinal absorption, excessive blood loss and/or increased needs. Fe overload is also responsible of number of diseases. The RDA for adult males and females aged 19-50 yr is 8 and 18 mg, respectively, while for those >50 yr (both male and female) the RDA is 8 mg. This study investigated the daily intake of dietary Fe in the Pakistani population. Food samples were collected from major cities/districts of the country using market basket methods. A total of 31 daily diets were prepared and analysed for Fe contents using AAS. Results showed that average Fe concn. in the diet was 52 ± 15 mug/g, leading to an average daily dietary intake of 31 ± 9.5 mg/day, with a variation of 12-52 mg/day. These estimated values of daily Fe intake are approx. 2 times higher than the RDA set by international committee of radiological protection and US food and nutrition board. However, although these findings suggest that dietary Fe intake is sufficient, Fe bioavailability may be low as a major portion of the diet is based on plant foods (71%), followed by milk products (17%) and other miscellaneous items, with only a low intake of animal foods (5%); furthemore, Fe inhibitors (i.e. phytate in plant foods, tannin and polyphenols in tea and Ca) may affect Fe status. Thus, as the composition of the diet is likely to be the leading cause of Fe deficiency anaemia among the Pakistani population, corrections can be made by improving dietary habits, for example by increasing the quantity of animal foods or fortified foods and limiting intake of substances that can block non-haem Fe absorption, such as tea, coffee, etc.
