Which two carotenoids are rich in kale and highly concentrated in the retina's macula?
Answer
Lutein and Zeaxanthin
Kale is an exceptional source of specific carotenoids that are vital for maintaining long-term visual health, particularly against age-related degradation. The two pigments responsible for this protective effect are lutein and zeaxanthin. These compounds are unique because they selectively accumulate and become highly concentrated within the macula, which is the central region of the retina responsible for sharp, central vision. A steady dietary intake of foods rich in lutein and zeaxanthin, such as kale, is scientifically linked to a reduced risk of developing common vision impairments, including cataracts and age-related macular degeneration (AMD).
