Maria Fernandez has received nearly a half million dollars from the egg industry and writes papers like ”Rethinking dietary cholesterol." She admits that eggs can raise LDL cholesterol, bad cholesterol, but argues that HDL, so-called ”good cholesterol," also rises, thereby maintaining the ratio of bad to good. To support this assertion, she cites one study that she performed with Egg Board money that involved 42 people.
If we look at a meta-analysis, a measure of the balance of evidence, the rise in bad is much more than the rise in good with increasing cholesterol intake. The analysis of 17 different studies showed that dietary cholesterol increases the ratio of total to HDL cholesterol, suggesting that the favorable rise in HDL fails to compensate for the adverse rise in total and LDL cholesterol. Therefore, increased intake of dietary cholesterol from eggs may indeed raise the risk of coronary heart disease.
The Egg Board responded (as seen in my video, Does Cholesterol Size Matter?) by saying that the increased heart disease risk associated with eating eggs needs to be put in perspective relative to other risk factors, arguing that it's worse to be overweight than it is to eat eggs, to which the authors of the meta-analysis replied, ”Be that as it may, many people do not find it a major hardship to cut back on egg intake, whereas most people find it impossible to lose weight permanently."
