A high ratio of dietary animal to vegetable protein increases the rate of bone loss and the risk of fracture in postmenopausal women
Diet protein bone mineral density
2016/6/12
Different sources of dietary protein may have different
effects on bone metabolism. Animal foods provide predominantly
acid precursors, whereas protein in vegetable foods
is accompanied by base pre...
Protein intake and bone health: the influence of belief systems on the conduct of nutritional science
Protein intake bone health

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...
Determination of glutamine in muscle protein facilitates accurate assessment of proteolysis and de novo synthesis–derived endogenous glutamine production
Glutamine glutamic acid muscles
2016/6/1
Results of tracer studies indicate that skeletal muscle
contributes to <70% of overall glutamine production in
healthy adults; the contribution of de novo synthesis being estimated
at <60%. However...
Validation of a self-administered food-frequency questionnaire administered in the European Prospective Investigation into Cancer and Nutrition (EPIC) Study: comparison of energy, protein, and macronutrient intakes estimated with the doubly labeled water, urinary nitrogen, and repeated 24-h dietary recall methods

The validation of dietary assessment instruments is
critical in the evaluation of diet as a chronic disease risk factor.
Dietary protein and risk of ischemic heart disease in women
Protein intake animal protein disease risk
2016/6/1
Ingestion of animal protein raises serum cholesterol
in some experimental models but not in others, and ecologic
studies have suggested a positive association between
animal protein intake and risk...
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...

nitrogen balance protein metabolism elderly women
2016/5/31
Adequate protein nutrition could be used to
limit gradual body protein loss and improve protein anabolism
in the elderly.

Two German sisters aged 14 and 17 y were admitted
to the Tübingen eye hospital with a history of night blindness.
In both siblings, plasma retinol binding protein (RBP) concentrations
were below th...

Obesity is becoming more frequent in children;
understanding the extent to which this condition affects not only
carbohydrate and lipid metabolism but also protein metabolism
is of paramount import...
Mutations in the gene encoding retinol binding protein and retinol deficiency: is there compensation by retinyl esters and retinoic acid?

2016/5/31
Biesalski et al (1) present a novel case of 2 sisters aged 14 and
17 y with very low plasma retinol concentrations (0.19 mmol/L)
and plasma concentrations of retinol binding protein (RBP) below

The title and conclusions of the article, “Bioavailability of
iron glycine as a fortificant in infant foods,” by Fox et al (1) are
not supported by the data presented. Their data show that the

soy protein casein liquid-formula diets
2016/5/30
Substitution of soy protein for casein in the diet
decreases LDL cholesterol and increases HDL cholesterol. How
the 2 proteins affect lipoprotein(a) [Lp(a)], an independent risk

Acute effects of moderate dietary protein restriction in patients with idiopathic hypercalciuria and calcium nephrolithiasis
Idiopathic hypercalciuria dietary proteins nephrolithiasis
2016/5/30
High dietary protein intake is a potential risk factor
for nephrolithiasis because of its capacity to increase urinary calcium
and to facilitate lithogenesis through many other mechanisms.
