Antioxidants are nutrients found in plant-based foods that promote a healthy immune system. According to the U.S. Department of Agriculture (USDA), antioxidants such as vitamin A, vitamin C, vitamin E, beta-carotene, selenium and lycopene contribute significantly to one's overall health and wellness. Colorful fruits are a valuable source of these nutrients.
Blueberries
Berries are a significant source of antioxidants. According to the Mayo Clinic, blueberries in particular contribute numerous nutritional benefits. Blueberries may help prevent urinary tract infections, improve short-term memory and promote healthy aging. They are low in calories yet high in nutrients such as vitamin C--a useful antioxidant--and dietary fiber, which promotes digestive health and healthy weight management. Incorporate fresh or frozen blueberries into breakfast cereals, baked goods, fruit salads and desserts regularly for best results.
Apples
Apples also contain vitamin C. According to the Mayo Clinic, apples are known to help improve blood vessel health, aid in collagen formation and assist in iron absorption. They are low in calories and provide the body with water and dietary fiber. Apples are a convenient portable snack choice as well. Enjoy a variety of apples on a regular basis for best nutritional benefits. Slice apples to use as salad topping or bake apples with cinnamon and a touch of honey or crushed walnuts for a nutritious dessert alternative.
Cherries
Cherries are rich in flavonoids, plant compounds that offer antioxidant benefits. According to research published by the University of Michigan in 2009, healthy adults who consumed a cup and a half of frozen cherries reaped heightened levels of antioxidants. The antioxidants in cherries are the same chemicals that create their red color. In general, colorful fruits are valuable sources of antioxidants. Cherries are also associated with reduced risk for inflammation and heart disease. Incorporate fresh or frozen cherries into your diet regularly for optimum results.
Citrus Fruits
Citrus fruits provide benefits of antioxidants such as caffeic acid and ferulic acid. According to the USDA, these nutrients improve the immune system and may improve the maintenance of healthy eyesight as well as heart health. To reap the most antioxidant benefits from citrus fruits, incorporate oranges, grapefruit, lemons and tangerines into your diet.
