Antioxidants are substances that help protect your cells from harmful molecules called free radicals. Free radicals can occur from everyday things like infection or too much exercise, as well as from things like cigarette smoke or pollution.
When there are too many free radicals and not enough antioxidants to keep them in check, it causes oxidative stress. This imbalance is linked to various health problems such as heart disease, inflammation, certain cancers, and even aging.
Research shows eating a diet rich in fruits and vegetables can help, but it is not entirely clear if it is because of the antioxidants, or something else within these foods.
According to the USDA, the top antioxidant foods include:
1. small red beans
2. wild blueberries
3. red kidney beans
4. pinto beans
5. cultivated blueberries
6. cranberries
7. artichokes
8. blackberries
9. prunes
10. raspberries
11. strawberries
12. red delicious apples
13. Granny Smith apples
14. pecans
15. sweet cherries
16. black plums
17. russet potatoes
18. black beans
19. plums
20. Gala apples
21. dark leafy greens
Although antioxidant supplements are available, they come with potential health risks and could interact with medications. Getting antioxidants through food is your safest bet. Talk with your healthcare provider if you plan to increase your antioxidant intake.
