Research has shown that those who consume the highest levels of lutein and zeaxanthin have a 43% lower risk of developing macular degeneration, compared with those who consume the least.

Lutein and zeaxanthin are usually found in foods together. The best sources of these nutrients can be found in leafy green vegetables such as spinach, kale, and swish chard along with other foods like parsley, pistachios, and green peas. As lutein and zeaxanthin are carotenoids, these are better absorbed when eaten with healthy fats such as avocado or oils.

Vitamin C
