Leafy Greens
Like eggs, leafy greens such as spinach, kale, turnip greens, collard greens, and romaine lettuce, are all great sources of lutein and zeaxanthin. Studies have shown eating foods rich in these antioxidants can significantly reduce your risk of age-related macular degeneration, as well as non-Hodgkin's lymphoma. Greens are also packed with cancer-fighting antioxidants like beta carotene, vitamin C, and sulforaphane. Dark, leafy greens are also rich in vitamin K, a nutrient that plays a role in reducing bone loss and preventing fractures.
Spinach provides folate, which research shows can dramatically improve your short-term memory. Eating folate rich foods helps lower your risk for heart disease and cancer by slowing down wear and tear on your DNA. Spinach has a very high ORAC score, which is a measurement of a food's ability to destroy the free radicals that cause damage in your body. The higher the ORAC score, the better a food is for you.
In addition to these internal health benefits, leafy greens help maintain glowing, youthful looking skin and ward off shorter-term illnesses such as colds. You can be sure to get enough greens by adding them to salads, sandwiches, or soups.
