The n−3 fatty acids eicosapentaenoic acid and docosahexaenoic acid increase systemic arterial compliance in humans
Systemic arterial compliance n− 3 fatty y acids plasma lipids arterial pressure cardiovascular disease eicosapentaenoic acid docosahexaenoic acid
2016/12/19
Background: n−3 Fatty acids influence vascular function, but the effect of individual fatty acids on systemic arterial compliance (SAC) has not been reported. SAC, which reflects arterial e...
Effects of cocoa powder and dark chocolate on LDL oxidative susceptibility and prostaglandin concentrations in humans
Cocoa powder dark chocolate LDL oxidation
2016/6/14
Flavonoids are polyphenolic compounds of plant
origin with antioxidant effects. Flavonoids inhibit LDL oxidation
and reduce thrombotic tendency in vitro. Little is known about
how cocoa powder and ...
Examining the effect of a nutrition intervention on immune function in healthy humans: what do we mean by immune function and who is really healthy anyway?
nutrition intervention immune function
2016/6/14
Designing studies to examine the role of nutrition in disease
prevention can provide interesting challenges. For example,
assessing the effect of nutritional interventions on immune function
is oft...

the flavonoid quercetin, which ...
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...

Fatty acids dietary intake prostate tissue
2016/6/13
Dietary fatty acids may influence prostate carcinogenesis.
Although the standard for assessing dietary effects
in humans is the semiquantitative food-frequency questionnaire,
the extent to which se...
Consumption of high doses of chlorogenic acid, present in coffee, or of black tea increases plasma total homocysteine concentrations in humans
Polyphenol coffee tea
2016/6/12
In population studies, high intakes of coffee are
associated with raised concentrations of plasma homocysteine, a
predictor of risk of cardiovascular disease. Chlorogenic acid is a
major polyphenol...
Calcium supplementation of chocolate: effect on cocoa butter digestibility and blood lipids in humans
energy content of chocolate confectionery fat digestibility
2016/6/12
The digestibility of cocoa butter was reported in
animal but not human studies to be low (60–70% and 89–94%,
respectively). These differences could be due to the much higher
ratio of calcium to fat...

cholesterol lipids carbon chain length
2016/6/12
Dietary behenic acid (22:0) is poorly absorbed.
Because of its low bioavailability compared with other fatty
acids and because of its very long chain length, the effect of
dietary behenic acid (beh...
