Daily egg consumption in hyperlipidemic adults - Effects on endothelial function and cardiovascular risk

Background
Limiting consumption of eggs, which are high in cholesterol, is generally recommended to reduce risk of cardiovascular disease. However, recent evidence suggests that dietary cholesterol has limited influence on serum cholesterol or cardiac risk.

Objective
To assess the effects of egg consumption on endothelial function and serum lipids in hyperlipidemic adults.

Methods
Randomized, placebo-controlled crossover trial of 40 hyperlipidemic adults (24 women, 16 men; average age = 59.9 ± 9.6 years; weight = 76.3 ± 21.8 kilograms; total cholesterol = 244 ± 24 mg/dL). In the acute phase, participants were randomly assigned to one of the two sequences of a single dose of three medium hardboiled eggs and a sausage/cheese breakfast sandwich. In the sustained phase, participants were then randomly assigned to one of the two sequences of two medium hardboiled eggs and 1/2 cup of egg substitute daily for six weeks. Each treatment assignment was separated by a four-week washout period. Outcome measures of interest were endothelial function measured as flow mediated dilatation (FMD) and lipid panel.

Results
Single dose egg consumption had no effects on endothelial function as compared to sausage/cheese (0.4 ± 1.9 vs. 0.4 ± 2.4%; p = 0.99). Daily consumption of egg substitute for 6 weeks significantly improved endothelial function as compared to egg (1.0 ± 1.2% vs. -0.1 ± 1.5%; p < 0.01) and lowered serum total cholesterol (-18 ± 18 vs. -5 ± 21 mg/dL; p < 0.01) and LDL (-14 ± 20 vs. -2 ± 19 mg/dL; p = 0.01). Study results (positive or negative) are expressed in terms of change relative to baseline.

Conclusions
Egg consumption was found to be non-detrimental to endothelial function and serum lipids in hyperlipidemic adults, while egg substitute consumption was beneficial.

So four legs ok (eggs==sausage+cheese), but two legs (egg substitute) better?

As a dietary substitute for eggs, egg substitute is comprised of 99% egg whites and provide 12 key vitamins and nutrients, including riboflavin, B12, folate, and pantothenic acid, while excluding the cholesterol contribution of the egg yolk[13]. Although nutritionally similar to eggs, egg substitute contains emulsifiers, stabilizers, and artificial color and are on average three times as expensive as regular eggs.

Hmm, so egg whites are better than whole eggs...?!? Considering that all of us could likely use "better" than just "status quo" for health.

Remember that the study was performed on hyperlipidemic adults. As we already know from previous research, unless you have an existing cholesterol problem, eggs are fine. This study just confirms it, as well as show that even hyperlipidemic adults aren't affected that much from moderate egg consumption.

Here's another study/report specifically on egg yolk...
