Free radicals are known to harm the cells, contribute negatively to ageing, and trigger heart disease, cancer, type 2 diabetes, and Alzheimer’s.
Zeaxanthin is the pigment that gives paprika (made from bell peppers), corn, saffron, and many other plants their characteristic color. Zeaxanthin is also found in high levels in dark green vegetables, orange and yellow fruits, and egg yolks.
Zeaxanthin is a carotenoid found in the cell of human eye. The other two carotenoids human eyes contain are lutein and meso-zeaxanthin. While lutein and Zeaxanthin are found in leafy vegetables and fruits, meso-zeaxanthin is rarely found in the diet.
Zeaxanthin plays a role in protecting the eyes from the harmful effects of oxidation and light-induced damage. It has potent antioxidant properties and is linked to several health benefits, such as reducing the risk of age-related macular degeneration, glaucoma, and cataracts.
In the peripheral part of the retina, there is a 2:1 lutein:zeaxanthin ratio, while zeaxanthin becomes the dominant pigment in the macular area.
Zeaxanthin can be used, for example, as an additive in feeds for poultry to intensify the yellow color of the skin or to accentuate the color of the yolk of their eggs. It is also suitable for use as a colorant, for example, in the cosmetics and food industries.
