Although iron is an essential mineral for maintaining good health, excessive amounts are toxic. Nowadays, much interest is focused on the mechanisms and regulation of iron metabolism by down-regulation of the hormone hepcidin. The HAMP gene encodes for hepcidin appears to be exceptionally preserved. Disorders of iron metabolism could lead to iron overload, mainly causing the rare disease heredi...

This study was conducted to investigate the effect of external iron status and arsenic species on chelant-enhanced iron bioavailability and arsenic uptake. Rice seedlings (Oryza sativa L.) were used as model plant, and were grown in artificially contaminated sandy soils irrigated with Murashige and Skoog (MS) culture solution. Arsenate uptake in roots and shoots of rice seedlings were affected ...

Bioavailability of a single iron source is difficult to predict. It can vary considerably due to the enhancing or inhibitory effects of other food components on iron absorption and, especially for the less-available sources, it is strongly influenced by the physical characteristics of the iron compound itself. It is sometimes difficult for the food manufacturer or food scientist to interpret th...

Iron deficiency is a major public health concern and nutritional approaches are required to reduce its prevalence. The aim of this study was to examine the iron bioavailability of a novel home fortificant, the "Lucky Iron Fish™" (LIF) (www.luckyironfish.com/shop, Guelph, Canada) and the impact of dietary factors and a food matrix on iron uptake from LIF in Caco-2 cells. LIF released a substanti...

Repeated surveys have shown that the magnitude of nutritional anaemia is of public health concern in India. Though reduced intake of iron is a major aetiological factor, low intake or an imbalance in the consumption of other haematopoietic nutrients, their utilization; increased nutrient loss and/or demand also contribute to nutritional anaemia. In India, cereals and millets form the bulk of th...

BACKGROUND Phytic acid is a strong inhibitor of iron absorption from fortified foods. In adults, this inhibitory effect can be overcome by adding ascorbic acid with the iron fortificant or by using a "protected" iron compound such as NaFeEDTA. In addition, the use of NaFeEDTA as an iron fortificant has been reported to increase zinc absorption in adult women. No information is available on iron...
