Increased iron bioavailability from lactic-fermented vegetables is likely an effect of promoting the formation of ferric iron (Fe3+)
AbstractBackground Lactic fermentation of foods increases the availability of iron as shown in a number of studies throughout the years. Several explanations have been provided such as decreasedExpand

Formation of reactive aldehydes (MDA, HHE, HNE) during the digestion of cod liver oil: comparison of human and porcine in vitro digestion models.
In this work, we investigated lipid oxidation of cod liver oil during gastrointestinal (GI) digestion using two types of in vitro digestion models. In the first type of model, we used human GIExpand

Impaired uptake of β-carotene by Caco-2 human intestinal cells in the presence of iron
At present, there are conflicting data regarding whether or not β-carotene has a positive effect on iron absorption. This study was undertaken to evaluate possible interactions involved in the uptakeExpand

Iron Transport through Ferroportin Is Induced by Intracellular Ascorbate and Involves IRP2 and HIF2α
A few tightly regulated transport proteins mediate iron absorption across the intestinal epithelium. At the basolateral border of intestinal cells there is one identified transporter, ferroportin,Expand

The effects of hydrothermal processing and germination on Fe speciation and Fe bioaccessibility to human intestinal Caco-2 cells in Tartary buckwheat.
Tartary buckwheat is a gluten-free crop with great potential as a wheat substitute. Iron (Fe) is an important mineral element in staple foods which is required in sufficient bioaccessible quantities.Expand

Ascorbic acid uptake affects ferritin, Dcytb and Nramp2 expression in Caco-2 cells
BackgroundAscorbic acid (vitamin C) enhances iron uptake in human intestinal cells. It is commonly believed that the enhancement is due to the capacity of ascorbic acid to reduce ferric iron toExpand

Determination of Fe2+ and Fe3+ in Aqueous Solutions Containing Food Chelators by Differential Pulse Anodic Stripping Voltammetry
The objective was to investigate interactions between iron and food chelators in an aqueous environment. The net complexation were investigated by DPASV in a NaClO4 electrolyte using a platinumExpand

Proposing a Caco-2/HepG2 cell model for in vitro iron absorption studies.
The Caco-2 cell line is well established as an in vitro model for iron absorption. However, the model does not reflect the regulation of iron absorption by hepcidin produced in the liver. We aimed toExpand
