The effects of fat loss after bariatric surgery on inflammation, serum hepcidin, and iron absorption: a prospective 6-mo iron stable isotope study
obesity iron deficiency iron absorption hepcidin inflammation stable isotopes
2018/12/18
Background: Iron deficiency is common in obese subjects. This may be due to an increase in serum hepcidin and a decrease in iron absorption from adiposity-related inflammation.
Vegetarian diets often contain more copper than
do nonvegetarian diets, but observations of decreased plasma
copper associated with vegetarian diets suggest that these diets
have lower copper bioav...
Guar gum does not impair the absorption and utilization of dietary nitrogen but affects early endogenous urea kinetics in humans
Guar gum dietary nitrogen urea kinetics
2016/6/14
Viscous gums enhance viscosity in the upper gastrointestinal
lumen, quickly disturbing motility and promoting
fluid secretion.
Folic acid enrichment of bread does not appear to affect zinc absorption in young women
Folate folic acid fortification, enrichment
2016/6/14
In several countries cereals are now enriched with
folic acid to reduce the risk of neural tube defects. Human studies
suggest that folic acid interferes with zinc absorption. This
raises concerns ...
Green tea or rosemary extract added to foods reduces nonheme-iron absorption
green tea rosemary radioisotopes
2016/6/13
Phenolic compounds act as food antioxidants. One
of the postulated mechanisms of action is chelation of prooxidant
metals, such as iron. Although the antioxidative effect is desirable,
this mechani...
Diminished and erratic absorption of ergocalciferol in adult cystic fibrosis patients
Vitamin D cystic fibrosis malabsorption
2016/6/13
Osteoporosis diminishes the quality of life in
adults with cystic fibrosis (CF). Vitamin D deficiency resulting
from malabsorption may be a factor in the etiology of low bone
mineral density (BMD) ...
Improving iron absorption from a Peruvian school breakfast meal by adding ascorbic acid or Na2EDTA
Iron iron absorption stable isotope
2016/6/12
Iron-fortified school breakfasts have been introduced
in Peru to combat childhood iron deficiency.
Effect of ascorbic acid intake on nonheme-iron absorption from a complete diet
nonheme-iron ascorbic acid
2016/6/12
Ascorbic acid has a pronounced enhancing effect
on the absorption of dietary nonheme iron when assessed by
feeding single meals to fasting subjects. This contrasts with the
negligible effect on iro...
Absorption of iron from unmodified maize and genetically altered, low-phytate maize fortified with ferrous sulfate or sodium iron EDTA
Iron absorption iron deficiency anemia
2016/6/12
Reducing the phytate content in grains by genetic
manipulation is a novel approach to increasing nonheme-iron
absorption from mixed diets. Fractional iron absorption from a
genetically modified str...
Digestion and absorption of 2 fat emulsions with different droplet sizes in the human digestive tract
Fat droplet size fat lipolysis
2016/6/2
The extent of fat emulsification affects the activity
of digestive lipases in vitro and may govern digestion and
absorption of dietary fat.
Using stable isotopes to assess mineral absorption and utilization by children
Calcium absorption iron absorption mineral requirements
2016/6/2
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...
Sitostanol administered in lecithin micelles potently reduces cholesterol absorption in humans
deuterium spectrum analysis mass
2016/6/1
Phytosterol feeding in human clinical trials has
had generally small and inconsistent effects on serum cholesterol
concentrations, raising doubts about the importance of phytosterols in
natural die...
Inositol phosphates with different numbers of phosphate groups influence iron absorption in humans
Phytate inositol phosphates iron absorption
2016/6/1
Inositol hexaphosphate (IP6) is a well-known
inhibitor of iron absorption, whereas the effects of the less-phosphorylated
derivatives of IP6 are less known.
Effects of high compared with low calcium intake on calcium absorption and incorporation of iron by red blood cells in small children
Calcium absorption iron absorption preschool children
2016/5/31
The potential benefits of increasing calcium
intake in small children must be balanced with the potential risk
to iron utilization from high calcium intakes.
