as a precursor to the neurotransmitter acetylcholine), liver health, and cell membrane integrity. Research links higher choline intake to better cognitive performance in older adults and improved neurodevelopmental outcomes in children when consumed during pregnancy. To access these benefits, eat the whole egg—the yolk holds the majority of vitamins, minerals,
and choline.
5. Eye Health Through Lutein and Zeaxanthin
While leafy greens are well-known sources of the carotenoids lutein and zeaxanthin, egg yolks also provide meaningful amounts—and the fat in eggs enhances their absorption. These compounds accumulate in the retina, where they filter harmful blue light and help protect against age-related macular degeneration, a leading cause of vision loss.
Studies indicate that lutein and zeaxanthin from eggs are more bioavailable than from plant sources alone. Two boiled eggs daily will not replace a diet rich in dark leafy greens, but they offer a practical, absorbable contribution to long-term eye health.
