Equations for predicting the energy requirements of healthy adults aged 18–81 y
Energy requirements energy expenditure isotopes
font style='font-size:12px;'>
2016/5/31
Recent studies have questioned the accuracy of
using the current recommended dietary allowances (RDAs) to
predict usual energy requirements in adults.
Comparison of air-displacement plethysmography with hydrostatic weighing and bioelectrical impedance analysis for the assessment of body composition in healthy adults
Adiposity body fat body density humans

2016/5/31
Over the past decade, considerable attention has
been paid to accurately measuring body composition in diverse
populations. Recently, the use of air-displacement plethysmography
(AP) was proposed a...
Holo-transcobalamin is an indicator of vitamin B-12 absorption in healthy adults with adequate vitamin B-12 status1,2,3
Transcobalamin holo-transcobalamin holo-TC vitamin B-12 vitamin B-12 absorption
font style='font-size:12px;'>
2008/12/11
Background:It has been hypothesized that the response of holo-transcobalamin (holo-TC) to oral vitamin B-12 may be used to assess absorption. To develop a reliable clinical absorption test that uses h...
A randomised cross-over trial in healthy adults indicating improved absorption of omega-3 fatty acids by pre-emulsification
adults healthy

2008/4/23
The health benefits of increased intakes of omega-3 fatty acids are well established but palatability often presents a problem. The process of emulsification is used in the food industry to provide a ...
Gastrointestinal symptoms and blood indicators of copper load in apparently healthy adults undergoing controlled copper exposure
SOD nonceruloplasmin copper fraction homeostasis

2016/12/29
The objective was to assess acute gastrointestinal effects and blood markers of copper status in apparently healthy adults who underwent controlled copper exposure for 2 mo.
Meta-analysis of nitrogen balance studies for estimating protein requirements in healthy adults
Protein requirements nitrogen balance elderly

2016/12/27
Data were gathered from published nitrogen balance studies that had as their primary objective either the estimation of basal or maintenance requirements or the testing of the adequacy of specific nit...
Efficiency of utilization of wheat and milk protein in healthy adults and apparent lysine requirements determined by a single-meal [1-13C]leucine balance protocol
Healthy adults protein quality milk wheat stable isotopes leucine balance nitrogen balance amino acid requirements
font style='font-size:12px;'>
2016/12/20
Background: We recently reported better wheat-protein utilization and a higher apparent lysine requirement than would be predicted, because of adaptive mechanisms of lysine conservation. However,...
Comparison of the antioxidant effects of Concord grape juice flavonoids α-tocopherol on markers of oxidative stress in healthy adults
Antioxidant α-tocopherol grape juice flavonoids LDL oxidation oxygen radical absorbance capacity protein carbonyls urinary F2 -isoprostanes
font style='font-size:12px;'>
2016/12/20
Background: Concord grape juice (CGJ) is a rich source of flavonoids, which have greater antioxidant efficacy in vitro than does α-tocopherol; however, the efficacies of flavonoids and α-tocopher...
Threonine requirement of healthy adults,derived with a 24-h indicator amino acid balance technique
Threonine requirements indicator amino acid oxidation amino acid balance leucine healthy adults
font style='font-size:12px;'>
2016/12/17
Background: Because we question the validity of the 1985 FAO/ WHO/UNU upper requirement for threonine of 7 mg·kg−1·d−1, we proposed a tentative mean requirement of 15 mg·kg−1·d&...
Human adult amino acid requirements: [1-13C]leucine balance evaluation of the efficiency of utilization and apparent requirements for wheat protein and lysine compared with those for milk protein in healthy adults
Healthy adults protein quality protein turnover stable isotopes nitrogen balance
font style='font-size:12px;'>
2016/6/7
Background: There is considerable debate about the human lysine
requirement and the consequent nutritional value of wheat protein.
Objective: We used a novel [1-13C]leucine balance protocol to
exam...
Twenty-four–hour oral tracer studies with L-[1-13C]lysine at a low (15 mg·kg21 ·d21) and intermediate (29 mg·kg21 ·d21) lysine intake in healthy adults
Lysine oral tracer studies amino acids oxidation, healthy adults
font style='font-size:12px;'>
2016/6/7
Background: We proposed previously that the mean lysine
requirement value is <30 mg·kg21·d21 rather than the proposed
1985 FAO/WHO/UNU estimate of the upper range of the requirement,
which is 12 mg...
Lactose does not enhance calcium bioavailability in lactose-tolerant, healthy adults
Lactose-tolerant adults calcium absorption, strontium test bioavailability

2016/6/3
Background: There is evidence from animal studies that lactose
has a beneficial effect on intestinal calcium absorption. However,
data concerning the effect of lactose on calcium absorption
in lact...
