Another Egg Study

Title: Eggs modulate the inflammatory response to carbohydrate restricted
diets in overweight men

http://www.nutritionandmetabolism.com/content/5/1/6

Background
Carbohydrate restricted diets (CRD) consistently lower glucose and insulin
levels and improve atherogenic dyslipidemia [decreasing triglycerides and
increasing HDL cholesterol (HDL-C)]. We have previously shown that male
subjects following a CRD experienced significant increases in HDL-C only if
they were consuming a higher intake of cholesterol provided by eggs compared
to those individuals who were taking lower concentrations of dietary
cholesterol. Here, as a follow up of our previous study, we examined the
effects of eggs (a source of both dietary cholesterol and lutein) on
adiponectin, a marker of insulin sensitivity, and on inflammatory markers in
the context of a CRD.

Methods
Twenty eight overweight men [body mass index (BMI) 26-37 kg/m2] aged 40-70 y
consumed an ad libitum CRD (% energy from CHO:fatrotein = 17:57:26) for 12
wk. Subjects were matched by age and BMI and randomly assigned to consume
eggs (EGG, n=15) (640 mg additional cholesterol/day provided by eggs) or
placebo (SUB, n=13) (no additional dietary cholesterol). Fasting blood
samples were drawn before and after the intervention to assess plasma
lipids, insulin, adiponectin and markers of inflammation including
C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-I+/-),
interleukin-8 (IL-8), monocyte chemoattractant protein-1 (MCP-1),
intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion
molecule-1(VCAM-1).

Results
Body weight, percent total body fat and trunk fat were reduced for all
subjects after 12 wk (P 0.0001). Increases in adiponectin were also
observed (P 0.01). Subjects in the EGG group had a 21% increase in this
adipokine compared to a 7% increase in the SUB group (P 0.05). Plasma CRP
was significantly decreased only in the EGG group (P 0.05). MCP-1 levels
were decreased for the SUB group (P 0.001), but unchanged in the EGG group.
VCAM-1, ICAM-1, TNF-alpha and IL-8 were not modified by CRD or eggs.

Conclusions
A CRD with daily intake of eggs decreased plasma CRP and increased plasma
adiponectin compared to a CRD without eggs. These findings indicate that
eggs make a significant contribution to the anti-inflammatory effects of
CRD, possibly due to the presence of cholesterol, which increases HDL-C and
to the antioxidant lutein which modulates certain inflammatory responses.

Any ideas on what a placebo egg is? Maybe smart beaters or whatever
they
call those cholesterol free egg substitutes?

Thanks for the link Rog. I'm gonna go have some eggs in about an hour
or so.

I just had five eggs this morning. Yay! Farm-fresh, local eggs too;
less than a week old. Yum. Not exactly pasture-raised--there's not
much pasture in Illinois in February--but the yolks are still a much
deeper orange than store-bought eggs, showing the chickens are finding
more than grain to eat.

But is it necessarily the dietary cholesterol in the eggs that
matters?

In particular I'm interested in the amino acid balance and fat content
of the substitute.

Eggs were called "Eggs, Nature's most nearly perfect food" for a
while because they had the best known amino acid balance of
any food that had been measured at the time. What if this effect
is from fixing a previously unknown amino acid deficiency? What
if it's from one of the types of fatty acid in the yolk? There are
other factors in an egg than cholesterol.

Thanks for the post.

While most of the biochemistry here goes over my head, I think it is
probably improper to conclude that cholesterol is the key. Eggs have lots
of stuff in them. They may be right, of course.

It is too bad they do not say how many eggs the subjects got per day.

Wouldn't it be wild if the supplement stores started selling cholesterol
pills to prevent inflammation and thus heart disease!

I backed it out.
640 mg cholesterol works out to about 3 large - extra large eggs.

Thank you.

I just checked Fitday. If dietary cholesterol is good, I'm in great shape.

My blood tests check a lot of things, but they don't seem to check for
inflammation, yet.

What is this "inflammatory response"? I haven't experienced it as I can
think of, nor did I really read any "overweight man" switching to Atkins
claiming that he was struck by an inflammation. I would be glad to know
what it is.

I think it's a scam and something used to sell studies.

I wondered that as well. Very many people have reported reduced
swelling and that's a "response" toward the good. Not everyone
reports such, but many do.

Propaganda to get funding. Chuckle.
