Background: Celiac disease (CD), as an autoimmune disease has initiated since ingestion of food containing gluten. Constant intolerance to gluten causes damages of the small intestinal mucosa. One reason of mal-absorption in children and infants is CD. Additionally, about 75% of newly identified patients with CD have low bone mineral density (BMD). Many factors have role in metabolic bone disea...

Extensive gastric surgery is known to cause bone disorders (osteomalacia/osteoporosis)7,9 possibly related to an impaired capacity for the absorption of dietary calcium1,5. The absence of gastric acid after gastric resection may impair bioavailability of insoluble dietary calcium because gastric acid is the most important factor for solubilization of otherwise insoluble calcium salts5. The stom...

1.5 and 3% of Maillard's reaction products (MRP), prepared by heating glycine and glucose, were incorporated ino a semi-synthetic diet. The diet was sterilized by irradiation. MRP caused a change in apparent absorption of calcium and magnesium in germfree (GF) and conventional (CV) rats. The absorption of these minerals was reduced in the small intestine of CV and GF, perhaps due to the action ...

The renal biosynthesis of 1,25-dihydroxyvitamin D (l,25-(OH)2B) is known to be stringently regulated by extensive ionic and hormonal controls. Quantitation of this mineral regulating hormone by radio­ receptor assay has recently enabled a study of its influence and syn­ thetic control during physiological states of growth and reproduction. The data reveal that 1,25-(0H)̂ D is strikingly elevated...

A metabolism study was conducted with rabbits to determine the effect of consumption of 5% dietary Senecio jacobaea (SJ) on tissue mineral levels and mineral excretion. Gastro-intestinal (GIT) absorption of pyrrolizidine alkaloids (PA) from SJ was also studied by monitoring excretion into urine and feces and by the use of ligated gut segments in vitro. Inclusion of SJ into a diet containing add...

BACKGROUND previous studies have shown that non-digestible inulin-type fructan intake can increase intestinal mineral absorption in both humans and animals. However, this stimulatory effect on intestinal absorption may depend on experimental conditions such as duration of fermentable fiber intake, mineral diet levels and animals' physiological status, in particular their age. OBJECTIVES the a...

Adequate mineral intake is a crucial part of a healthy diet for children-it supports appropriate growth and development and provides protection against childhood conditions like anemia and helps to prevent future adult diseases such as osteoporosis. Challenges in performing and interpreting studies in infants and children have hampered the accurate assessment of their mineral utilization. Many ...

[1] The Bodélé depression of northern Chad is considered one of the world’s largest sources of atmospheric mineral dust. Mineral composition of such transported dust is essential to our understanding of climate forcing, mineralogy of dust sources, aerosol optical properties, and mineral deposition to Amazon forests. In this study we examine hyperspectral information acquired over the Bodélé by ...

Phytic acid is a bioactive compound widely distributed in plant foods. Due to its molecular structure, phytic acid has affinity to polyvalent cations, such as minerals and trace elements, and could in this way interfere with their intestinal absorption in man and animals. Most studies in humans have therefore concentrated on the effect of phytate on mineral absorption and deficiencies. Currentl...
