Eggs Contain Lutein and Zeaxanthin- Antioxidants that have Major Benefits for Eye Health

One of the consequences of ageing is that eyesight tends to get worse. There are several nutrients that help counteract some of the degenerative processes that can affect our eyes.

Two of these are called lutein and zeaxanthin. They are powerful antioxidants that accumulate in the retina of the eye.

Studies show that consuming adequate amounts of these nutrients can significantly reduce the risk of cataracts and macular degeneration, two very common eye disorders.

Egg yolks contain large amounts of both lutein and zeaxanthin.

In one controlled study, eating just 1.3 egg yolks per day for 4.5 weeks increased blood levels of lutein by 28–50% and zeaxanthin by 114–142%.

Eggs are also high in vitamin A, which deserves another mention here. Vitamin A deficiency is the most common cause of blindness in the world.

SUMMARY
The antioxidants lutein and zeaxanthin are very important for eye health and can help prevent macular degeneration and cataracts. Eggs are high in both of them.
