I graduated 2006 with a BS in Nutrition, and had to dig out one of my old textbooks to help you out ï¿½?? Iï¿½??m going out on a limb, and assuming that she believes eggs are the devil because of their high cholesterol content.
Hereï¿½??s what you tell your girlfiend: ï¿½??Contrary to widespread belief, changing the amount of cholesterol in the diet has only a minor influence on blood cholesterol concentration in most people. This is because compensatory mechanisms are engaged, such as HDL activity and scavenging excess cholesterol and the down-regulation of cholesterol synthesis by dietary cholesterol. It is well known, however, that certain individuals respond strongly, and others weakly, to dietary cholesterol. This phenomenon, which may have a genetic basis, is further complicated by the observation that significant within-person variability exists independent of diet, a fact that clearly confounds the results of intersubject studies.ï¿½??
She wasnï¿½??t right about the egg whites either; while the majority of the protein is in the white (3.6g white/2.7g yolk) itï¿½??s almost 50/50. Also, all of the nutrients are in the yolk. As Charles Poliquin Says, ï¿½??only dorks eat egg whitesï¿½??.
