Iron absorption in breast-fed infants:effects of age,iron status,iron supplements,and complementary foods
Infants human milk breast milk nonheme-iron absorption stable isotopes iron status dietary iron intake complementary food iron supplements dietary regulator adaptation
2016/12/19
Background: Iron supplements are often recommended for older breast-fed infants, but little is known about factors affecting iron absorption from human milk or supplements.Objective: We inve...
Phytosterols that are naturally present in commercial corn oil significantly reduce cholesterol absorption in humans
Phytosterols oils diet cholesterol mass spectrometry deuterium
2016/12/17
Background: Although supplementing the diet with large quantities of phytosterols reduces cholesterol absorption and LDL-cholesterol concentrations, very little is known about the smaller amounts...
Dietary silicon intake and absorption
Silicon orthosilicic acid phytolithic silica silicon intake gastrointestinal absorption bioavailability cohort study diet nutrition bone formation
2016/12/17
Background: Increasing evidence suggests that silicon is important in bone formation. The main source of silicon for humans is the diet, but the bioavailability of silicon from solid foods is not...
Effects of vitamin D metabolites on intestinal calcium absorption and bone turnover in elderly women
Elderly women vitamin D calcitriol calcium absorption bone turnover calcium intake 25-hydroxyvitamin D sunlight
2016/12/17
Background: The relative importance of vitamin D metabolites in the regulation of gut calcium absorption has not been well studied in elderly women living in an environment with abundant sunlight...
DERMAL ABSORPTION AND DISTRIBUTION OF 14C CARBARYL IN WISTAR RATS
carbaryl dermal absorption Wistar rats beta radiation
2010/12/27
The level of 14C carbaryl was determined in blood (leukocytes, erythrocytes, all blood cells, plasma) and organs (brain, heart, lungs, liver, spleen, skin at the site of exposure) of male Wistar rats ...
Adaptation in iron absorption: iron supplementation reduces nonheme-iron but not heme-iron absorption from food
Iron supplementation heme iron nonheme iron iron absorption fecal ferritin serum ferritin
2016/6/8
Background: Results of cross-sectional studies suggest that in
healthy people, iron absorption adapts to meet physiologic
needs and stabilize iron stores, but this has not been adequately
tested in...
Dietary protein and phosphorus do not affect calcium absorption
Calcium absorption dietary protein dietary phosphorus estrogen Roman Catholic nuns
2016/6/8
Background: Variation in absorption efficiency explains more
of the variability in calcium balance than does actual calcium
intake. Several investigators have suggested that the relatively
high pho...
Searching for the determinants of intestinal calcium absorption
intestinal calcium absorption determinants
2016/6/8
The amount of calcium consumed regulates the efficiency of
intestinal calcium absorption; calcium absorption efficiency
(fractional calcium absorption) increases when calcium intakes
are low and de...
Factors associated with calcium absorption efficiency in pre- and perimenopausal women
Calcium absorption efficiency variation, premenopausal women perimenopausal women
2016/6/7
Background: The amount of calcium ingested by an individual
may affect several chronic conditions, including osteoporosis,
hypertension, and colon cancer. However, individuals vary in
their ability...
Folate absorption in women with a history of neural tube defect–affected pregnancy
Folate neural tube defect absorption bioavailability, stable isotopes women
2016/6/7
Background: The risk of neural tube defects (NTDs) is significantly
reduced by supplemental folic acid. NTD risk may be
associated with impaired absorption of polyglutamyl folate, the
primary form ...
Detection of impaired intestinal absorption of long-chain fatty acids: validation studies of a novel test in a rat model of fat malabsorption
Isotope labeling stable isotopes absorption, dietary fat metabolism malabsorption syndromes bile enterohepatic circulation bile salts rats bile deficiency
2016/6/7
Background: Classic fat balance studies detect fat malabsorption
but do not discriminate between the potential causes of malabsorption,
such as impaired intestinal lipolysis or reduced
uptake of fa...
Neural tube defects (NTDs) are among the most prevalent
debilitating birth defects worldwide. By 1992, after a series of trials
and intervention studies, the scientific world was finally convinced
...
Iron absorption from ferrous bisglycinate and ferric trisglycinate in whole maize is regulated by iron status
trisglycinate iron amino acid chelates iron fortification iron status maize phytate serum ferritin
2016/6/7
Background: There is a need to determine whether iron absorption
from iron amino acid chelates is protected from inhibition
by dietary phytate and regulated normally by iron status.
Objective: The ...
Prediction of dietary iron absorption: an algorithm for calculating absorption and bioavailability of dietary iron
Humans iron absorption heme iron nonheme iron algorithm diet meals bioavailability iron status, iron requirements phytate polyphenols ascorbic acid meat soy protein alcohol eggs calcium
2016/6/7
Background: Dietary iron absorption from a meal is determined
by iron status, heme- and nonheme-iron contents, and amounts
of various dietary factors that influence iron absorption. Limited
informa...
Intestinal absorption of b-carotene ingested with a meal rich in sunflower oil or beef tallow: postprandial appearance in triacylglycerol-rich lipoproteins in women
b-carotene beef tallow bioavailability chylomicrons, fat intestinal absorption polyunsaturated fat postprandial, retinyl esters saturated fat sunflower oil triacylglycerolrich lipoproteins very-low-density lipoproteins VLDLs
2016/6/7
Background: Evidence indicates that different types of fat have
different effects on the postprandial plasma triacylglycerol
response. Therefore, the type of fat may influence the appearance
of b-c...
