Lutein and zeaxanthin are carotenoids that have a particular role to play in human health. Both compounds accumulate in the macula of the eye, and here they protect the retina and other parts from free radicals through their antioxidant activity. A diet high in lutein and zeaxanthin is therefore beneficial to eye health and can significantly reduce the risk of specific eye disorders related to free radical damage. Dietary sources of lutein and zeaxanthin tend to have strong yellow colours as these pigments reflect the light waves necessary to be visualised as yellow. Foods such as egg yolks and yellow flower petals are often rich sources of lutein and zeaxanthin. However, lutein and zeaxanthin can also be found in green leafy vegetables such as kale, parsley and spinach, with the green chlorophyll pigment masking the yellow colour of the carotenoids. Generally, plant diets are high in both lutein and zeaxanthin, but eating foods that contain higher amounts can be a good strategy to optimise eye health and protect eyesight.
