Protein intake and bone health: the influence of belief systems on the conduct of nutritional science
Protein intake bone health
2016/6/12
It was first shown nearly 80 y ago, and has been confirmed
many times since, that ingestion of protein increases urinary
calcium excretion. Most such work involved isolated protein
feedings, and qu...
Physical activity, protein intake, and appendicular skeletal muscle mass in older men
Aging sarcopenia uniaxial accelerometer
2016/5/31
Aging is associated with physical inactivity, low
energy intake, and loss of skeletal muscle mass. It is not clear
whether regular physical activity and adequate dietary protein
intake can attenuat...
Association of dietary protein intake and coffee consumption with serum homocysteine concentrations in an older population1–3
Homocysteine tHcy diet
2016/5/30
Elevated blood concentrations of total homocysteine
(tHcy) have been implicated in the pathogenesis of atherosclerotic
cardiovascular disease. Previous studies identified suboptimal
nutritional sta...
Prospective study of dietary protein intake and risk of hip fracture in postmenopausal women
Aging, diet epidemiology hip fractures
2016/5/30
The role of dietary protein intake in osteoporosis
remains controversial. Protein is an important structural component
of bone and protein supplementation improves the medical
outcome of hip fractu...
Inadequate protein intake affects skeletal muscle transcript profiles in older humans 1,2,3
Dietary protein aging skeletal muscle transcript profile microarray gene expression
2008/12/11
Background: Inadequate dietary protein intake causes adverse changes in the morphology and function of skeletal muscle. These changes may be reflected in early alterations in muscle messenger RNA leve...
Protein intake during the period of complementary feeding and early childhood and the association with body mass index and percentage body fat at 7 y of age 1,2,3
Dietary protein complementary feeding children obesity body fatness cohort study
2008/12/11
Background: A high protein intake during infancy and early childhood has been proposed to increase the risk of subsequent obesity.Objective: We analyzed the association of different protein intakes du...
Urea-nitrogen production and salvage are modulated by protein intake in fed humans: results of an oral stable-isotope-tracer protocol and compartmental modeling
stable-isotope-tracer protocol compartmental modeling
2016/12/30
The influence of protein source on postprandial urea kinetics is poorly understood, despite its nutritional significance with respect to nitrogen homeostasis. Furthermore, traditional tracer infusion ...
Frailty amplifies the effects of aging on protein metabolism: role of protein intake
Aging frailty protein metabolism
2017/1/4
Compared with healthy women, frail women had higher rates of whole-body protein synthesis and breakdown per kg fat-free mass and lower rates of muscle protein breakdown when expressed as total amounts...

Protein bone mineral density bone loss
2017/1/3
We investigated the associations of dietary protein intake with baseline bone mineral density (BMD) and the rate of bone loss over 3 y in postmenopausal elderly women.
Iron indexes and total antioxidant status in response to soy protein intake in perimenopausal women
Antioxidant status ferritin iron indexes lipoprotein(a) menopause soy-protein isolate oxidation perimenopausal women
2016/12/19
Background: Elevated iron stores, oxidative stress, and estrogen deficiency may place postmenopausal women at greater risk of heart disease and cancer than premenopausal women.Objective: The...
Calcium intake influences the association of protein intake with rates of bone loss in elderly men and women
Calcium intake protein intake bone loss bone mineral density potential alkali calcium absorption vitamin D elderly
2016/12/17
Background: There is currently no consensus on the effect of dietary protein intake on the skeleton, but there is some indication that low calcium intakes adversely influence the effect of dietar...
