Abstract:
Tahfiz education has been well accepted by Muslims in Malaysia. Memorizing the Quran through rote learning can assistin improving the brain ability to process, store information and build memory. In addition, dietary intakes were reportedto contribute in the process of memorizing the Quran and to increase the levels of intelligence (IQ) among huffaz students.This cross-sectional study was conducted to measure and to determine the correlation between IQ and dietary intakeas well as between IQ and the level of trace elements among students in selected tahfiz schools and non-tahfiz school inSelangor. Questionnaires were used to obtain demographic data. Dietary intake was assessed via 3 days dietary record.Levels of trace elements in the nail samples were analyzed by using ICP-MS. Test for intelligence using WASI-II wasconducted to measure the students’ IQ. The results showed that there was a moderate positive correlation between IQ andcarbohydrate (r = 0.425, p < 0.001, a weak positive correlation between IQ and energy (r = 0.260, p < 0.05), vitaminB6 (r = 0.189, p < 0.05), vitamin B12 (r = 0.207, p < 0.05) and vitamin C (r = 0.211, p < 0.05). The levels of traceelements in nail samples showed no correlation with IQ, whereas there were moderate positive correlations between IQand dietary zinc (r = 0.375, p < 0.001) as well as between IQ and dietary iron (r = 0.303, p < 0.001). There was also amoderate positive correlation between IQ and the level of memorization (r = 0.375, p < 0.001). The results of stepwisemultiple linear regression showed that al-Quran memorization influence the level of IQ by 20 %. As a conclusion, dietaryintake of certain nutrients including energy, vitamins and selected trace elements can potentially improve memorizationactivities and also IQ.
