Antioxidants are nutrients that have disease-fighting properties. They are found primarily in fruits, vegetables and whole grains. According to the American Dietetic Association (ADA), antioxidants help strengthen the immune system and prevent diseases such as cancer. To improve your physical wellness, incorporate a variety of antioxidant-rich foods into your diet on a regular basis.
Vitamin C
Vitamin C is a water-soluble vitamin and antioxidant found in citrus fruits, citrus juices, berries, papayas, spinach, asparagus, green peppers, brussels sprouts, broccoli, watercress, red and yellow peppers, tomatoes and tomato juice, pineapples, cantaloupes, mangoes and guavas. Vitamin C assists in the body's formation and maintenance of bones, blood vessels and skin.
Lycopene
Lycopene is an antioxidant that's responsible for the deep colors of many fruits. Intake of this nutrient is associated with a lowered risk for prostate cancer as well as cardiovascular diseases. Tomatoes, tomato sauce and tomato juice provide substantial amounts of lycopene, while pink grapefruit and watermelon provide modest amounts.
Beta-Carotene
Beta-carotene is a plant pigment that helps create vitamin A in the body. According to nutrition specialist Melina Jampolis, M.D., beta-carotene and vitamin A support vision, bodily development, immune system strength and reproductive health. Consume a variety of dark orange, red, yellow and green vegetables and fruits, such as broccoli, kale, spinach, yams, carrots, red and yellow peppers, apricots, cantaloupes and mangoes to reap beta-carotene benefits. Since many of these foods are rich in vitamin C as well, additional immune system benefits may stem from their consumption.
