Which carotenoids in avocados help filter harmful blue light waves in the eye?
Answer
Lutein and zeaxanthin
Avocados contain specific carotenoids, namely lutein and zeaxanthin, that accumulate within the eye tissue. These compounds function actively as natural antioxidants directly inside the eye, where their role is critical in filtering out harmful, high-energy blue light waves that can contribute to damage over time. This protective mechanism helps reduce the risk of developing age-related macular degeneration (AMD) and cataracts. An important synergistic benefit is that because both lutein and zeaxanthin are fat-soluble nutrients, the natural fat content inherent in the avocado itself significantly enhances the body’s ability to absorb and utilize these beneficial pigments when consumed as part of the whole fruit.
