Abstract

Absorption of nonheme iron has been studied extensively by the use of extrinsic tag radio-labeled iron to meals. Nevertheless, this method is unsuitable for screening large number of meals. The purpose of this study is to determine and compare iron availability from various kinds of meals in laboratory conditions that mimic the human stomach. Three hundred and seventy two common meals from the Siriraj Hospital kitchen were tested. The results of iron availability tests on the 372 Siriraj meals were classified as having low (5.77 ± 2.42%), intermediate (12.42 ± 1.55%), high (17.7 ± 1.44%) and very high (25.8 ± 3.65%) iron availability. Only meals of high and very high iron availability (22.1 ± 4.99%) provided sufficient amounts of iron for the special requirement of teenagers and woman of childbearing age (2.22 to 3.24 mg of Fe per day) while meals of low and intermediate iron availability (8.12 ± 3.84%) provided only 1.02 mg of iron per day. An average amount of estimated iron availability from the 372 meals was 14.12 ± 8.2% of 1.77 mg per day. This was slightly inadequate because 2.06 to 2.15 mg were required per day for the high-risk groups. Results of this study indicated that 42.7% of Siriraj meals adequately provided the physiologic requirement of the high-risk segments of the population, but 57.3% of the meals did not. Improvement of food choices to increase dietary iron intake can be accomplished by including meat, fish or poultry and a source of vitamin C in every meal.
