Availability of food iron.
نویسندگان
چکیده
Iron has been extracted from 25 common foods under conditions resembling those prevailing in the stomach under physiological conditions. In most cases less than half the iron in the foods is released into solution. The soluble iron is mainly in ionizable form, except in the case of meat products and black pudding. The amount of food iron released is influenced by cooking and the presence of iron-binding substances in some foods. The total dietary iron probably does not represent the amount available for absorption.

An in vitro method for estimation of iron availability from meals13
An in vitro method for estimating food iron availability is described. The method involves simulated gastrointestinal digestion followed by measurement of soluble, low molecular weight iron. Mixtures of foods (meals) were homogenized and exposed to pepsin at pH 2. Dialysis was used to adjust the pH to intestinal levels and digestion was continued after the addition of pancreatin and bile salts....

متن کاملIron availability from iron-fortified spirulina by an in vitro digestion/Caco-2 cell culture model.
Iron deficiency, one of the most important nutritional problems in the world, can be caused not only by foods deficient in iron but also by poor availability of dietary iron. Iron food fortification in combination with highly available iron from supplements could effectively reduce this deficiency. The aim of this study was to examine the iron availability from iron-fortified spirulina. We have...
متن کاملRice Enrichment by Genetic Engineering for Combating Iron and Zinc Deficiency
Iron deficiency anemia and zinc deficiency are among the most recognized forms of micronutrient malnutrition and about two billion of people around the world suffer from it. Monotonous diets based on staple cereals are in fact a poor source of iron and zinc. Rice is a staple food for more than half of the world's population. Various methods have been proposed for food enrichment, but many of t...
متن کاملIron and zinc in vitro availability in pearl millet flours (Pennisetum glaucum) with varying phytate, tannin, and fiber contents.
Simulations of gastro-intestinal digestion, used to estimate in vitro iron and zinc availability, were performed on two kinds of samples: (i) samples with decreased phytate contents from whole pearl millet flour and (ii) nondephytinized or dephytinized samples from two pearl millet grain fractions, a decorticated fraction with low fiber and tannin contents and a bran fraction with high fiber an...
متن کاملEffects of roasting and boiling of quinoa, kiwicha and kañiwa on composition and availability of minerals in vitro.
BACKGROUND Andean indigenous crops such as quinoa (Chenopodium quinoa), kiwicha (Amaranthus caudatus) and kañiwa (Chenopodium pallidicaule) seeds are good sources of minerals (calcium and iron). Little is known, however, about mineral bioavailability in these grains. Thus the aim of the present study was to determine the iron, calcium and zinc potential availability in raw, roasted and boiled q...
