Eggs Are Good for Macular and Visual Function

Lutein, zeaxanthin and meso-xanthin are important catotenoid pigments found in the macula which is the most important part of retina. Macula subserves the central vision. The above pigments are not made in our body and we must consume dietary products which contain them. Yellow of egg is an important source of lutein and zeaxanthin pigments.

Naturally, macular pigments (MP) play an important role in proper visual function by providing protection from oxidative stress that causes damage to retinal photoreceptors. Most commonly, MP components in dietary and medical supplementation forms not only enhance the visual function in the macula, but also protect the degeneration process advancing with aging. Especially in the developing world, any alterations in MP with aging leads to the onset of age-related macular degeneration (AMD).Most commonly, eggs in the dietary form are considered to be a rich source of carotenoid pigments such as lutein and zeaxanthin. Previous studies have reported that enrichment of MP following supplementation with a combination of L, Z and MZ have shown clinically-relevant improvements in visual function, downstream regulation of oxidative stress, and cognitive function. A collaborative study in this direction by Kelly and co-researchers was published in the British Journal of Nutrition, 2017.

The study confirmed that eight weeks of consumption of eggs increased the amount of lutein and zeaxanthin in the macula.
