Consumption of One Egg Per Day Increases Serum Lutein and Zeaxanthin Concentrations in Older Adults without Altering Serum Lipid and Lipoprotein Cholesterol Concentrations
Eggs really have gotten a bad rap over the past decade or so because we were so caught up in the mistaken notion that dietary cholesterol = serum cholesterol. This just isn’t true. In addition to being a good protein source, the veg-a-fed eggs will be high is omega-3 fatty acids. As if this wasn’t exciting enough, the coloring of the yolk is provided by carotenoids.
This study finds that the consumption of one egg per day is able to raise the serum levels of the carotenoids lutein and zeaxanthin; both of which are known to protect the retina.
