EGG AND HEART DISEASE
Consumption of whole
eggs can be a part of a heart healthy diet, even in those with existing
coronary heart
disease, a
new study has found.
Research
from Yale University explored the impact of daily
whole egg consumption in men and women with coronary heart disease.
The
subjects were randomized to consume either two eggs, half a cup of egg
substitute or a high-carbohydrate breakfast for six weeks as part of their
typical diet.
The
subjects who ate either whole eggs or egg substitute did not experience any
negative impact in total cholesterol, blood pressure, body weight or
endothelial function.
Research
from the University
of Connecticut suggested
that daily whole egg consumption may have a positive effect on the function and
composition of HDL cholesterol in adults with metabolic syndrome.
Subjects followed a carbohydrate-restricted
diet, and consumed either three eggs per day or an equivalent amount of egg
substitutes.
After
12 weeks, subjects consuming whole eggs experienced improvements in HDL (good
cholesterol) composition and ability to remove cholesterol from the blood.
Those
eating three whole eggs daily also had HDL that was lower in triacylglycerol
and higher in a beneficial component of egg yolks (phosphatidylethanolaime)(2).
“Taken
together with previously established benefits of egg intake on HDL profiles,
these findings further support the notion that eggs serve as a functional food
to reduce cardiovascular disease risk in individuals with metabolic syndrome,”
Catherine Andersen, lead study author and PhD candidate at the University of
Connecticut said.
Researchers
at University of Missouri presented data comparing the
effects of a normal-protein cereal breakfast (15 percent meal calories),
high-protein egg and pork breakfast (40 percent meal calories) and no breakfast
on satiety in overweight/obese adolescents who normally skip breakfast.
The
group that consumed the high protein egg and pork breakfast reported a decrease
in hunger and an increase in fullness compared to the individuals eating a high
protein breakfast also voluntarily reduced their intake by more than 400
calories per day over the 12-week study.
No
significant differences were seen in weight between groups; however, breakfast
skippers were found to have significant increases in percent body fat mass
compared to those who ate the normal and high protein breakfasts.
This
study supports the benefits of a high protein breakfast as a weight management
strategy among overweight and obese adolescents.
