Which carotenoids accumulate in the macula for vision support?
Answer
Lutein and Zeaxanthin
The vegetable's ability to support ocular health is largely attributed to its content of Vitamin A and specific carotenoids, namely lutein and zeaxanthin. These two compounds are noted for their potent antioxidant properties and have a specific biological function: they accumulate in the macula of the eye. Once present in the macula, they serve a protective role by filtering out harmful high-energy blue light. This filtering action is believed to substantially reduce the long-term risk associated with developing serious ocular conditions such as age-related macular degeneration (AMD) and cataracts. Consuming foods rich in these substances is presented as a proactive dietary measure for long-term sight maintenance.
