22. Leafy greens
“Leafy greens such as kale or spinach are rich in nutrients like folate, which helps reduce the risk of heart disease, stroke, and osteoporosis. They are also rich in antioxidants such as lutein, carotenoids, and beta-carotene, which prevent diseases caused by oxidative stress. Lutein is useful for healthy eyes, as it protects against macular degeneration,” Guillot says. “A 2018 study also showed that one serving a day of leafy greens could help slow down cognitive decline.”
Furthermore, a study in the journal JRSM Cardiovascular Disease found that a high daily consumption of green leafy and cruciferous veggies (such as kale) significantly reduced incidence of several types of cardiovascular disease.
