Which combination of nutrients is listed as key nutrients for cataracts?

• A. Lutein, Vitamin E, Vitamin C, Selenium.
• B. Lutein and Vitamin C only
• C. Vitamin A, Vitamin D, Zinc
• D. Selenium and Vitamin E only

Answer: (C)

The key idea here is that cataracts are linked to oxidative stress and the health of lens cells, so nutrients that support antioxidant defenses and lens metabolism are especially relevant. Vitamin A supports the integrity and health of epithelial tissues in the eye and participates in maintaining normal cellular function in ocular tissues, which helps keep the lens environment stable. Zinc serves as a crucial cofactor for several enzymes, including those involved in antioxidant defenses and in processing vitamin A, helping protect the lens from oxidative damage and supporting normal lens metabolism. Vitamin D adds anti-inflammatory and potential anti-oxidative benefits that can further support ocular tissues and reduce inflammatory processes that may contribute to cataract development. When these nutrients are combined, they cover essential aspects of lens maintenance and oxidative protection, making this trio a well-supported choice for cataract-related nutrition.

While other nutrients like lutein, vitamin C, vitamin E, and selenium also support eye health and antioxidant capacity, the specific combination of vitamin A, vitamin D, and zinc aligns with mechanisms that directly support lens maintenance and antioxidant enzyme function, which is why it is considered the best fit for key nutrients related to cataracts.
