What Are Some Common Foods That Are Antioxidants?

Artichokes, beans, cranberries and pecans are all common foods with high levels of antioxidants. Antioxidants, nutrients and enzymes that counteract the damaging effect of oxidation in the human body, are also present at high levels in blueberries, blackberries, russet potatoes, walnuts and hazelnuts.

Other fruits high in antioxidants include prunes, raspberries, strawberries, apples and sweet cherries. Blueberries contain more antioxidants than any other commonly consumed fruit.

Other common vegetables that rank high include spinach, olives, red onions, shallots and broccoli. Red beans, kidney beans and pinto beans are also great sources of antioxidants.

Seed and nut sources include flaxseeds, chestnuts, almonds, roasted soybeans and processed soy, such as tempeh. Many spices are high in antioxidants, including ground cloves, ground cinnamon and oregano. Beverages that rank high include tea, coffee and red wine, which contain antioxidants known as flavonoids.

Scientists say antioxidants could play a role in preventing cancer, heart disease, stroke, Alzheimer's disease, Rheumatoid arthritis and cataracts. Antioxidants come in a variety of forms, including vitamin C, vitamin E, beta-carotene and minerals such as selenium and manganese.

Antioxidants counteract damage done by highly unstable free radicals inside the human body, or harmful molecules that damage cells, proteins and DNA. External free radicals are also formed from pollution, x-rays and cigarette smoke.
