The present study was supported by the Kuwaiti Flour Mills and Bakeries Company (Kuwait City, Kuwait), the International Atomic Energy Agency (Vienna, Austria), ETH Zurich (Switzerland), Medicor Foundation (Liechtenstein) and the Kuwait Institute for Scientific Research (KISR) (Kuwait City, Kuwait).
We thank the faculty members and the college students for their participation in the study. At the Swiss Federal Institute of Technology (Zurich, Switzerland), we thank E. Windhab for the facilities and support to optimise the microcapsules, C. Zeder for the help with the technical and laboratory analysis, J. Nuessli for her support in the sensory evaluation of the biscuits, and R. Buechel for the X-ray pattern measurements. We thank the Kuwaiti Flour Mills and Bakeries Company in Kuwait for the technical advice and support in producing and supplying the fortified biscuits.
At the Kuwait Institute for Scientific Research (KISR), we thank, in alphabetic order, A. Ali, A. Al-Azmi, S. Al-Hamli, J. Al-Saqer, B. Dashti and I. Ilyan for their help in conducting the study. At the Ministry of Health in Kuwait and associated Al-Sabah Hospital, we thank the dietitians and the technical staff for their help in conducting the laboratory analysis.
We also thank L. Davidsson (International Atomic Energy Association) for the support for the study, M. Haldimann at the Ministry of Public Health, Switzerland in conducting the biscuit and capsule iodine content measurements, and W. Jahn (Dr Paul Lohmann GmbH KG, Emmertal, Germany) for the supply of the dried micronised FeSO4.
R. B., M. B. Z., S. N. Al-H., N. Al-H. and R. F. H. participated in the design of the study. R. B., M. B. Z., N. P. and R. F. H. developed the microcapsules. S. N. Al-H., R. B. and M. B. Z. conducted the study and T. Z. and Y. K. helped in collecting the data. R. B. and M. B. Z. wrote the first draft of the manuscript. All of the authors edited the manuscript.
