Are egg yolks really as bad as smoking?

Harcombe also stresses the positives shown in the study for those who ate the most eggs. "People eating an average 4.68 egg yolks per week have lower total cholesterol, lower triglycerides, higher HDL and lower LDL than people eating an average of 0.41 egg yolks per week. Omelet anyone?
"However, this also doesn't display a consistent relationship total cholesterol is highest at the mid range of egg yolk consumption, an average of 2.3 per week. Triglycerides and LDL are also highest at the midpoint of egg yolk consumption, an average of 2.3 per week. (Not that I care about any 'cholesterol levels,' but just to comment on the data in the article from people who do care about 'cholesterol levels.')
"BMI, by the way, peaks at the midpoint of egg consumption and is lowest at the highest level of egg consumption. Low carbers know why.'"
She also pointed out the Conflict of Interest section of the study which states, "Dr. Spence and Dr. Davignon have received honoraria and speaker's fees from several pharmaceutical companies manufacturing lipid-lowering drugs, and Dr. Davignon has received support from Pfizer Canada for an annual atherosclerosis symposium; his research has been funded in part by Pfizer Canada, AstraZeneca Canada Inc and Merck Frosst Canada Ltd."
"Alternatively, this data could be interpreted completely differently. The data shows the individuals who ate the most eggs were the oldest and had the most plaque after their stroke. Perhaps the eggs actually had a protective effect allowing those who ate the most eggs to withstand more plaque buildup and live the longer before having a stroke. Those individuals who ate the fewest eggs had a stroke an average of 14 years earlier than those who ate the most eggs. Perhaps if they would have been eating more eggs, they would have lived longer without a stroke.
"It is important to remember that these epidemiological studies do not show cause and effect. They merely show correlation. They serve as a point of reference to form a hypothesis to be tested in prospective studies."
