Postprandial whole-body protein metabolism after a meat meal is influenced by chewing efficiency in elderly subjects1,2,3
Leucine kinetics protein metabolism meat chewing efficiency elderly
2008/12/11
Background: The rate of protein digestion affects protein utilization in elderly subjects. Although meat is a widely consumed protein source, little is known of its digestion rate and how it can be af...
Efficiency of calcium absorption is not compromised in clinically stable prepubertal and pubertal girls with cystic fibrosis
bone calcium stable isotopes
2017/1/3
Reduced bone mass is common in both children and adults with cystic fibrosis (CF) and may be a consequence of inadequate calcium absorption. The effect of CF on intestinal calcium absorption and reten...
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
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,...
Snacks consumed in a nonhungry state have poor satiating efficiency:influence of snack composition on substrate utilization and hunger
Snack appetite satiety substrate oxidation metabolic response hormonal response behavioral response insulin glucose fatty acids obesity weight gain
2016/12/19
Background: Several epidemiologic studies suggest that snacking may play an etiologic role in obesity.Objective: We assessed the behavioral and metabolic consequences of a high-carbohydrate ...
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...
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
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...
