6. Helps Maintain Eye Health
All types of summer squash (and winter squash, too) offer a good dose of phytonutrients like vitamin C, manganese, beta carotene, lutein and zeaxanthin that protect eye health. Lutein and zeaxanthin are two types of carotenoid antioxidants found in zucchini that often get attention for defending the eyes from age-related diseases, thus offering natural treatment for macular degeneration, cataracts and glaucoma. They work by protecting the retina, cornea and macula from UV light damage and oxidative stress that can lead to loss of vision and even blindness. In addition to protecting the delicate tissues of eyes, they can keep skin youthful and free from signs of aging, too.
