Like spinach and other leafy greens, egg yolks are also a good source of lutein and zeaxanthin. In one study, researchers
found that lutein levels increased by 26%, while zeaxanthin levels increased by 38% when subjects ate one egg per day. They
also found that eating an egg-a-day did not impact LDL or HDL cholesterol or triglycerides. Specialty eggs are also available
that have significantly more lutein per egg, due to simply feeding hens more carotenoid-rich feed. Egg yolks are also a natural
source of vitamin D, which may reduce the risk for ARMD.
