Vitamin D status affects serum parathyroid hormone concentrations during winter in female adolescents: associations with forearm bone mineral density
25-hydroxyvitamin D adolescent females bone mineral density
2016/6/14
Vitamin D deficiency leads to secondary hyperparathyroidism,
which has a negative effect on bone metabolism
in the elderly. Puberty is an important time of bone metabolism
and growth. The effect of...
Energy density of foods affects energy intake across multiple levels of fat content in lean and obese women
Energy density fat content energy intake
2016/6/13
The results of previous studies indicated that
energy density, independent of fat content, influences energy
intake. In most studies, however, both fat content and energy
density were lower than in...
Energy density of foods: building a case for food intake management
Energy density food intake management
2016/6/13
The case for the energy density of foods being an important
factor in regulating short-term food intake is strong (1–4). The
results of classic studies of food intake in organisms ranging
from blow...
Dietary cholesterol from eggs increases the ratio of total cholesterol to high-density lipoprotein cholesterol in humans: a meta-analysis
Dietary cholesterol eggs total cholesterol
2016/6/13
Several epidemiologic studies found no effect of
egg consumption on the risk of coronary heart disease. It is possible
that the adverse effect of eggs on LDL-cholesterol is offset
by their favorabl...
Association between urinary potassium, urinary sodium, current diet, and bone density in prepubertal children
Bone mineral density dietary intake urinary sodium

Our understanding of the role of nutrients in bone
development in children is limited.
Dietary glycemic load assessed by food-frequency questionnaire in relation to plasma high-density-lipoprotein cholesterol and fasting plasma triacylglycerols in postmenopausal women
glycemic index glycemic load women
2016/6/12
In metabolic studies, both greater carbohydrate
intakes and higher glycemic indexes (GIs) raise fasting triacylglycerol
concentrations. In epidemiologic studies, dietary
glycemic load (GL) is posit...
Empty calories and phantom fullness: a randomized trial studying the relative effects of energy density and viscosity on gastric emptying determined by MRI and satiety
energy content fullness gastric emptying MRI viscosity
2018/12/3
Background: Stomach fullness is a determinant of satiety. Although both the viscosity and energy content have been shown to delay gastric emptying, their relative importance is not well understood.
Effects of dietary viscosity and energy density on total daily energy consumption by young Peruvian children
Viscosity energy density amylase
2016/6/1
Results of prior studies of the effect of viscosity
reduction of high-energy-density, starch-containing diets on young
children’s energy intakes are inconsistent, possibly because of differences
in...
Effect of a lifestyle intervention on bone mineral density in premenopausal women: a randomized trial
bone markers osteocalcin N-telopeptides
2016/5/31
The positive association between body weight and
bone mineral density (BMD) is well documented; in contrast, the
effect of changes in body weight on BMD is not well understood,
particularly, in nor...
Previous milk consumption is associated with greater bone density in young women
Bone density diet premenopausal women
2016/5/31
Dietary calcium and milk intakes at specific ages
may influence bone mineral measures at specific sites during
development of peak bone mass.
Four-component model of body composition in children: density and hydration of fat-free mass and comparison with simpler models
Body fat dual-energy X-ray absorptiometry total body water
2016/5/31
Body composition in children is generally measured
by 2-component (2C) models, which are subject to error
arising from variation in fat-free mass (FFM) composition. The
4-component (4C) model, whic...
Energy density but not fat content of foods affected energy intake in lean and obese women
Energy density fat intake human food intake
2016/5/31
Studies have shown that energy intake increases
when both the fat content and energy density of the entire diet
increases. When the fat content and energy density vary independently
of one another,...
Potassium, magnesium, and fruit and vegetable intakes are associated with greater bone mineral density in elderly men and women
Bone mineral density dietary intake food-frequency questionnaire
2016/5/31
Osteoporosis and related fractures will be growing
public health problems as the population ages. It is therefore of
great importance to identify modifiable risk factors.
An independent, inverse association of high-density-lipoprotein-cholesterol concentration with nonadipose body mass
serum lipids cardiovascular disease HDL cholesterol
2016/5/31
Increasing body mass index (BMI) is associated
with progressively lower serum HDL-cholesterol concentrations,
although the underlying body-composition compartment
accounting for this unfavorable li...
A very-low-fat diet is not associated with improved lipoprotein profiles in men with a predominance of large, low-density lipoproteins
Lipoproteins low-fat diet LDL subclasses
2016/5/30
We found previously that men with a predominance
of large LDL particles (phenotype A) consuming highfat
diets (40–46% fat) show less lipoprotein benefits of low-fat
diets (20–24% fat) than do men w...
