Solution

Identifying Carotenoids for Macular Degeneration Prevention

  1. Understanding the Context

    • Macular degeneration is a leading cause of vision loss, particularly in older adults. Some carotenoids have been studied for their potential protective effects on eye health.

  2. Relevant Carotenoids

    • Lutein: Known for its role in filtering harmful blue light and its antioxidant properties.
    • Zeaxanthin: Often found alongside lutein, it plays a similar role in protecting the retina.
    • Beta-carotene: A precursor to vitamin A, it also has antioxidant properties but is less specifically associated with macular health.

  3. Evaluation of Choices

    • Vitamin A: While essential for vision, it's not a carotenoid itself, and its relationship to reducing macular degeneration is less direct compared to lutein and zeaxanthin.
    • Lutein and Zeaxanthin: Strongly supported by research for their protective roles against macular degeneration.
    • Beta-carotene: Has some benefits but is not as prominently linked to macular degeneration risk reduction as lutein and zeaxanthin.

Conclusion

The carotenoids that may help lessen the risk of macular degeneration are Lutein and Zeaxanthin. Beta-carotene is beneficial but is not as closely associated with this specific outcome. Thus, the correct selections are Lutein and Zeaxanthin.
