Egg a day benefits unclear

Given that eggs have health benefits, including raising HDL cholesterol and bestowing a range of minerals and beneficial fatty acids, researchers set out to analyse whether people with daily consumption were more likely to develop heart or vascular disease.

The dose-response analysis of 17 published reports of prospective cohort studies found no such association.
