Discussion on Zinc in Maternal and Child Health

摘要

There are ongoing studies in infants and young children of developing countries providing data to begin estimating prevalence of inadequate zinc intakes. Relatively good models now exist to examine the efficiency of absorption in various situations and the effect of phytate as the major factor affecting absorption. The issue was raised about the value of conducting more bioavailability studies, while the major contributing factor is the prevalence of diarrhea in the population (Dr. Allen). In response, the speaker (Dr. Hambidge) agreed with the point made, and indicated that the cornerstone of normal condition is required before expanded to cover infectious diseases. Eventually, both models are needed. Data have begun to emerge in relation to possible inflammation role in the gut, and further studies are required to elucidate whether part or whole of zinc deficiency problem is due to infection.
