In fact, a 2013 study published in the journal Lipids showed that eating whole eggs actually increased levels of HDL (good) cholesterol, and allowed the HDL molecules to function more effectively. HDL cholesterol encourages removal of LDL (bad) cholesterol, so the more of it you have, the better, according to the Mayo Clinic. A 2010 article in the Journal of Nutritional Biochemistry produced similar findings, plus noted that the increased HDL levels in the egg-eating participants helped increase the participants’ lutein and zeaxanthin levels. Lutein and zeaxanthin are valuable nutrients that are especially good for your eyes. - See more at: http://www.livescience.com/50834-eggs-nutrition-facts.html#sthash.QKSW2tgb.dpuf
