Determination of phytate, iron, zinc, calcium contents and their molar ratios in commonly consumed raw and prepared food in malaysia.
The inhibitory effect of phytate on the bioavailability of iron, zinc and calcium was determined by measuring their molar ratios. A total of 29 food samples consisting of 12 rice and rice products, 5 wheat and wheat products, 5 grains and cereal based products and 7 different popular varieties of cooked rice and rice products were selected. The phytate content was analysed using anion-exchange ...
متن کاملDietary calcium does not exacerbate phytate inhibition of zinc absorption by women from conventional diets.
BACKGROUND Although calcium inhibits zinc bioavailability in rats, especially from high-phytate diets, the effect of calcium on zinc absorption by humans from practical diets remains unclear. OBJECTIVE The objective was to test the inhibitory effect of dietary calcium, in Western diets with high and low phytate content, on zinc absorption. DESIGN Using a 2 x 2 factorial design, zinc absorpt...
متن کاملAn estimate of phytate intake and molar ratio of phytate to zinc in the diet of the people in the United Kingdom.
OBJECTIVE To estimate the phytate intake and molar ratio of phytate to zinc in the diet of the people in the United Kingdom. DESIGN Tables of the phytate content of foods were developed from twenty-eight published and unpublished studies. They were then applied to the nutrient databank of the National Diet and Nutrition Survey (NDNS). The study is a retrospective analysis of data on daily con...
متن کاملChemical composition, calcium, zinc and phytate interrelationships in Aerva lanata (Linn) Juss. ex Schult leaves
The proximate, nutritive and anti-nutritive composition of the leaves of Aerva lanata were determined. The leaves were found to be moderately high in carbohydrate (26.6 g/100g), crude protein (22.6 g/100g) and ash (31.2 g/100g). Mineral composition (mg/100g) revealed that the leaves were high in P (187), and moderately high in other minerals such as K (47.9), Na (39.4), Ca (51.7), Mg (41.5), Zn...
متن کاملZinc availability and digestive zinc solubility in piglets and broilers fed diets varying in their phytate contents, phytase activity and supplemented zinc source.
The study was conducted to evaluate the effects of dietary zinc addition (0 or 15 mg/kg of Zn as inorganic or organic zinc) to three maize-soybean meal basal diets varying in their native Zn, phytic P contents and phytase activity (expressed in kg of feed: P- with 25 mg Zn and 1.3 g phytic P, P+ with 38 mg Zn and 2.3 g phytic P or P+/ENZ being P+ including 500 units (FTU) of microbial phytase p...
