Eggs are considered as perfect food due to their richness in various nutrients. There are various compounds present in them that play a role in benefitting the body in various ways.

The yellow-orange color of the yolk of duck eggs is from a natural pigment called carotenoid. It is an antioxidant that protects the cells and DNA from oxidative damage, which is a cause of chronic and age-related diseases.

Carotenoids like carotene, cryptoxanthin, zeaxanthin, and lutein are known to lower the risk of age-related muscular degeneration, cataracts, heart diseases, and some cancer types. All these carotenoids are present in egg yolk.(4,5)

Egg yolk is also rich in lecithin and choline. Choline is a vitamin-like nutrient that is essential for the formation of healthy cell membranes and lecithin is converted into choline in the body.(4, 5)

Choline is also essential for brain health. A study showed higher levels of choline in the blood were linked with better brain function.(6) It also supports the healthy brain development of the fetus.(7)
