Getting Antioxidants Through Colorful Fruits and Vegetables
Antioxidants are primarily found in fruit and vegetables, and various colors are said to represent different benefits. Frequently, fruit or vegetables with the same color provide the same cancer-fighting nutrient. As a result, it is best to eat a variety of colors because one antioxidant may not fight all cancers. In addition, the various colors will also provide you with a variety of vitamins and minerals.
Red Fruits and Vegetables: Lycopene
Red-colored fruit and vegetables contain lycopene, which may help prevent cancer, but is also good for your heart and memory. Foods that are red include watermelons, tomatoes, strawberries, red grapes, cherries, red apples, cranberries, pink grapefruit, pomegranates, raspberries, beets, red peppers, radishes, and red onions. Kidney and pinto beans are also considered red and provide the same benefits.
Orange and Fruits and Vegetables: Beta-Carotene, Carotenoids, and Vitamin C
Beta-carotene is another antioxidant that is found in orange-colored foods like carrots, cantaloupe, sweet potatoes, papayas, persimmons, pumpkin, apricot, and mangoes.
Yellow fruits and vegetables also contain carotenoids and include foods such as nectarines, oranges, pineapples, lemons, yellow squash, corn, yellow peppers, and butternut squash. Orange and yellow foods also have vitamin C that helps your immune system.
Green Fruits and Vegetables: Lutein and Indoles
Green foods contain lutein (good for eyes) and indoles that, in addition to possibly reducing your risk for cancer, also promote strong bones and teeth. Examples include broccoli, spinach, avocado, Brussels sprouts, green apples, green grapes, green olives, honeydew, kiwi, limes, green pears, cucumbers, celery, lettuce, green onions, okra, peas, green beans, asparagus, artichokes, arugula and zucchini. Some beans such as green lentils and edamame are also good sources. In addition, the green leafy vegetables, such as kale, collard greens, and spinach have beta-carotene.
Blue and Purple Fruits and Vegetables: Anti-Aging Antioxidants
Anti-aging antioxidants, anthocyanins and phenolics are frequently found in blue/purple foods. In addition, these antioxidants may help with memory function. Examples include blackberries, blueberries, black olives, plums, raisins, purple grapes, eggplant, and purple cabbage. Black beans would also fall into this category.
A Diet Rich in Vitamins
In addition, consuming foods high in Vitamins A, C, and E may also be beneficial to your health. Foods high in Vitamin A include liver, sweet potatoes, milk, and egg yolk. Examples of foods high in Vitamin C include most fruit and vegetables; vitamin E is found mainly in nuts and oils.
Overall, incorporating your diet to include a colorful variety of fruit and vegetables has multiple benefits. In addition to possibly preventing cancer, a nutritious diet is also good for your heart, vision, immune system, and living a healthy life.
