The following foods are good sources of antioxidants. Click on each one to find out more about their health benefits and nutritional information:. Lycopene is the antioxidant that gives tomatoes their rich red color.
When tomatoes are heat-treated, the lycopene becomes more bio-available easier for our bodies to process and use. However, studies have shown that cauliflower, peas, and zucchini lose much of their antioxidant activity in the cooking process.
Keep in mind that the important thing is eating a variety of antioxidant-rich foods, cooked and raw. There is no set recommended daily allowance RDA for antioxidants, but a high intake of fresh plant-based produce is considered healthful. It is worth remembering that, while studies link the consumption of fruits and vegetables with better overall health, it is not clear whether how far this is due to the activity of antioxidants.
In addition, caution is needed regarding supplements. The National Institutes of Health NIH warn that high doses of antioxidant supplements can be harmful.
A high intake of beta-carotene, for example, has been linked to an increased risk of lung cancer in smokers. A high dose of vitamin E has been found to increase the risk of prostate cancerand the use of some antioxidant supplements has been linked to a greater risk of tumor growth.
Antioxidant supplements may also interact with some medications. It is important to speak with a health provider before using any of these products.
Overall, research has not proven that taking any particular antioxidant as a supplement or through a food can protect against a disease. There may be some benefit for people at risk of age-related macular degeneration, but it is essential to seek advice from a doctor about whether to use supplements, and which ones to use.
Free radicals have been linked to a range of diseases, including heart disease, cancer, and vision loss, but this does not mean that an increased intake of antioxidants will prevent these diseases.
Antioxidants from artificial sources may increase the risk of some health problems. As a result, it is important to seek out natural sources of antioxidants, in the form of a healthful diet.
Consuming fruits and vegetables has been linked to a lower rate of chronic diseases, and antioxidants may play a role.
However, it is unlikely that consuming added antioxidants, especially in processed foods, will provide significant benefits. In addition, anyone considering taking antioxidant supplements should speak to a health provider first. Read the article in Spanish.

It also contains antioxidants that are anti-inflammatory and may help reduce high cholesterol and blood pressure, as well as protect heart and brain health. Eating a diet low in antioxidants can set you up for a higher risk of disease. |
| Become a Dietitian | Known as free radical scavengers, according to the NCI , antioxidants work against that oxidative stress anti-oxidative by helping to neutralize free radicals and other molecules in your body that can damage cells and tissues, Mahdi Garelnabi , PhD, an associate professor of biomedical and nutrition sciences at the University of Massachusetts-Lowell, tells SELF. They do this through a variety of mechanisms, such as by lending an electron to a free radical to make it less reactive or by binding to a substance in a way that prevents further reactions. By stabilizing these free radicals, antioxidants can also help your immune system function more efficiently and mitigate chronic inflammation, which is thought to be a driving force for many health problems, like cardiovascular disease and cancer. Antioxidants may also, through separate mechanisms, help repair DNA and cell membranes. Shen says. Wright explains. There are thousands of antioxidants, and they are not only present in highly hyped antioxidant foods or superfoods. You can find antioxidants in a broad range of foods—like fruits, vegetables, seafood, whole grains, and meats—as well as in a wide range of supplements, such as vitamins for immune system health, certain protein powders and meal replacements, and formulas with antioxidants for skin , just to name a few. More on supplements later! By Krissy Brady. By Ashia Aubourg. By Sara Coughlin. Some antioxidants are essential vitamins that your body needs to function, while others are essential minerals. Examples of antioxidant vitamins include the immune-boosting vitamins C found in brussels sprouts , red cabbage, and peppers , vitamin E found in almonds, sunflower seeds, and olive oil , and vitamin A, which your body makes from beta carotene found in collard greens, sweet potatoes , and cantaloupe. Examples of antioxidant minerals include selenium found in Brazil nuts, pork, and turkey and zinc found in oysters, beef, and pumpkin seeds. You can find these in plant, animal, and other dietary sources. A few examples of these antioxidants include carotenoid cousins of beta carotene, such as lycopene found in watermelon , tomato sauce, and ketchup and lutein and zeaxanthin found in spinach, romaine lettuce, and Swiss chard , chlorogenic acid found in coffee, apples, and eggplants , flavonoids found in berries, tea, and citrus fruits , and ergothioneine found in mushrooms, tempeh , oats, and kidney beans. As a whole, antioxidants can be helpful because they fight back against that oxidative stress, which is linked to the wide swath of health problems mentioned above. In one study published in the European Journal of Nutrition, researchers classified 23, Americans into four groups based on their antioxidant consumption. Research also indicates that high amounts of dietary antioxidants may influence your risk of developing type 2 diabetes and stroke. Giovannucci notes that high intake of lycopene appears to be associated with a lower risk of aggressive prostate cancer, 7 while high intake of beta-carotene appears to be associated with a lower risk of breast cancer particularly, estrogen receptor negative breast cancer. There are two main ways to get antioxidants: food and supplements. Experts generally suggest getting antioxidants from whole foods instead of dietary supplements for a few good reasons. As Dr. Giovannucci points out, there are many lesser-known compounds in foods—potentially thousands—that, at least in laboratory settings, have been shown to have antioxidant properties, along with the many other phytochemicals present in plants. By eating a variety of foods high in antioxidants, you get all the benefits linked to all the different phytonutrients, regardless of the particular roles they may play. Plus, these whole-food packages—like berries, greens, root veggies, nuts, whole grains, and coffee —are all-around really, really good for you. Antioxidant foods like fruits and veggies pack in a ton of other good stuff your body needs, like other essential vitamins and minerals, carbohydrates including fiber and naturally occurring sugars , and water. In other words, there are many reasons to include an ample array of antioxidant-rich foods in your diet every day. As for how much of these foods you should be eating to get enough antioxidants? For the antioxidants that fall into the essential-nutrient category, recommended daily allowances RDAs exist to help you plan your intake. With selenium , for example, the RDA is 55 micrograms per day. For some nutrients, like zinc and immune-boosting vitamins A, C, and E, you can find RDAs for your age and sex in the U. Dietary Guidelines for Americans. For instance, each day women ages 31 to 50 should shoot for 8 milligrams of zinc, micrograms of vitamin A, 15 milligrams of vitamin E, and 75 milligrams of vitamin C. Researchers are still working on that, Dr. Bolling says. For example, some antioxidants, like carotenoids, degrade quickly when heated or stored for long periods of time; others, like flavonoids, are more stable. So rather than trying to hit a specific amount, focus on adding various antioxidant-rich foods into your diet. The best way to enrich your diet with antioxidant foods is to eat plenty of fruits and vegetables the Dietary Guidelines recommend two and a half cups of vegetables and two cups of fruits per day , Dr. Garelnabi says. Nuts, whole grains, dark chocolate, and tea are also good antioxidant sources, as are lean meats and seafood, Dr. And again, diversity is important in your diet, since some antioxidants work better together, Dr. Wright suggests aiming for a colorful variety of foods high in antioxidants. Trying to include different colors on your plate is a good idea, since the color of fruits and vegetables can serve as a clue to their antioxidant content, suggests a study published in Current Research in Food Science. So what about supplements? When it comes to preventing diseases, for instance, researchers have done a lot of studies on various antioxidant supplements, including large, robust clinical trials, 11 and most have found that antioxidant supplements do not reduce the risk of developing diseases like heart disease and cancer, according to the NCCIH. Each has its own role and can interact with others to help the body work effectively. Flavonoids, flavones, catechins, polyphenols, and phytoestrogens are all types of antioxidants and phytonutrients, and they are all found in plant-based foods. Each antioxidant serves a different function and is not interchangeable with another. This is why it is important to have a varied diet. To obtain some specific antioxidants, try to include the following in your diet:. Vitamin C : Most fruits and vegetables, especially berries, oranges, and bell peppers. Vitamin E : Nuts and seeds, sunflower and other vegetable oils, and green, leafy vegetables. Beta-carotene : Brightly colored fruits and vegetables, such as carrots, peas, spinach, and mangoes. Lutein : Green, leafy vegetables, corn, papaya , and oranges. Selenium : Rice, corn, wheat, and other whole grains, as well as nuts, eggs, cheese, and legumes.

Electrons exist in pairs; free radicals are missing an electron. This is their weapon of sorts. Free radicals then damage DNA, cellular membranes and enzymes. Many foods that provide these nutrients also supply antioxidants called lutein and zeaxanthin, nicknamed the eye vitamins , found in brightly colored foods like fruits and vegetables — especially leafy greens and types that are deep orange or yellow. These antioxidants are believed to be easily transported around the body, especially to the delicate parts of the eyes called the macula and the lens. In fact, there are more than different types of carotenoids found in nature, but only about 20 make their way into the eyes. Of those 20, lutein and zeaxanthin are the only two macular carotenoids that are deposited in high quantities into the macular portion of the eyes, which is one of the earliest to be damaged during aging. Research shows that high-lutein sources like spinach are proven to help decrease eye-related degeneration and improve visual acuity. Similarly, flavonoid antioxidants found in berries, such as bilberries or grapes also great sources of the antioxidant resveratrol , may be especially beneficial at supporting vision into older age. Perhaps most noticeably, free radicals speed up the aging process when it comes to the appearance and health of your skin. Using antioxidants for skin may help combat this damage, especially from eating sources high in vitamin C, beta-carotene and other antioxidants. Vitamin A and C have been connected to a decrease in the appearance of wrinkles and skin dryness. Vitamin C, specifically, is a powerful antioxidant that can help reduce the effect of oxidative damage caused by pollution, stress or poor diet. Vitamin A deficiency has also been linked to skin dryness, scaling and follicular thickening of the skin. Similarly to how free radicals damage surface skin cells, keratinization of the skin, when the epithelial cells lose their moisture and become hard and dry, can occur in the mucous membranes of the respiratory, gastrointestinal tract and urinary tract. At this point, the data does not show that all antioxidants are effective in protecting against heart disease, but some, such as vitamin C, do seem to be. The American Journal of Clinical Nutrition featured a study that found those with high levels of vitamin C in their blood had almost a 50 percent decreased risk of stroke. Countless studies also have found that people who consume highly plant-based diets — loaded with things like fresh veggies, herbs, spices and fruit — have a better chance of living longer and healthier lives with less heart disease. Some research has unearthed a potential connection between antioxidants and cancer. In fact, studies have found that high intakes of vitamin A, vitamin C and other antioxidant foods could help prevent or treat several forms of cancer thanks to their ability to control malignant cells in the body and cause cell cycle arrest and apoptosis destruction of cancer cells. Retinoic acid, derived from vitamin A, is one chemical that plays important roles in cell development and differentiation, as well as cancer treatment. Lung, prostate, breast, ovarian, bladder, oral and skin cancers have been demonstrated to be suppressed by retinoic acid. Another study collected numerous references demonstrating the findings of retinoic acid in protection against melanoma, hepatoma, lung cancer, breast cancer and prostate cancer. Many studies have found that people eating plant-based diets high in antioxidants, such as the Mediterranean diet , have better protection over cognition. In addition to improving heart health and cognitive function, some research suggests that antioxidants could aid in the prevention of type 2 diabetes. For example, one animal model out of Japan showed that administering antioxidants to mice helped preserve the function of beta cells in the pancreas, which are responsible for the production of insulin. Another large review of 12 studies found that vitamin E helped reduce blood sugar levels, while vitamin C was effective at decreasing levels of oxidative stress. Antioxidants may be easier to add to your diet than you might think. Based on ORAC scores provided by Superfoodly based on research from a broad number of sources , below are some of the top antioxidant foods by weight:. The ORAC scores above are based on weight. This means that it might not be practical to eat high amounts of all of these antioxidant foods. Other high-antioxidant foods not listed above, which are still great sources and highly beneficial, include common foods like:. Try to consume at least three to four servings daily of these antioxidant-rich foods even more is better for optimal health. Along with antioxidant foods, certain herbs, spices and essential oils derived from nutrient-dense plants are extremely high in healing antioxidant compounds. Here is another list of the herbs you can try adding to your diet for increased protection against disease. Look for percent pure therapeutic grade oils, which are highest in antioxidants:. Other antioxidant-rich herbs include garlic, cayenne pepper and green tea. Aim to consume two to three servings of these herbs or herbal teas daily. The American Heart Association, Mayo Clinic and Cleveland Clinic recommend getting antioxidants from whole foods and a wide variety of sources. Glutathione is a peptide consisting of three key amino acids that plays several vital roles in the body, including helping with protein use, creation of enzymes, detoxification, digestion of fats and destruction of cancer cells. Glutathione peroxidase can prevent lipid peroxidation, which can fight inflammation. Derived naturally from foods like berries and leafy greens, quercetin seems to be safe for almost everyone and poses little risk. Most studies have found little to no side effects in people eating nutrient-dense diets high in quercetin or taking supplements by mouth short term. Amounts up to milligrams taken twice daily for 12 weeks appear to be very safe for helping manage a number of inflammatory health problems, including heart disease and blood vessel problems, allergies, infections, chronic fatigue and symptoms related to autoimmune disorders like arthritis. Lutein has benefits for the eyes, skin, arteries, heart and immune system, although food sources of antioxidants seem to be generally more effective and safer than supplements. Some evidence shows that people who obtain more lutein from their diets experience lower rates of breast, colon, cervical and lung cancers. Known for improving immunity, vitamin C helps protect against colds, the flu, and potentially cancer, skin and eye problems. Resveratrol is an active ingredient found in cocoa, red grapes and dark berries, such as lingonberries, blueberries, mulberries and bilberries. Astaxanthin is found in wild-caught salmon and krill and has benefits like reducing age spots, boosting energy levels, supporting joint health and preventing symptoms of ADHD. Selenium is a trace mineral found naturally in the soil that also appears in certain foods, and there are even small amounts in water. Selenium benefits adrenal and thyroid health and helps protect cognition. It may also fight off viruses, defend against heart disease and slow down symptoms correlated with other serious conditions, like asthma. Chlorophyll is very helpful for detoxification and linked to natural cancer prevention, blocking carcinogenic effects within the body, and protecting DNA from damage caused by toxins or stress. Cooking can alter the content of antioxidants in food, and certain cooking methods can have a different impact on antioxidant levels. One study published in Preventive Nutrition and Food Science evaluated the effects of different cooking methods on the antioxidant content of red pepper to determine which methods can help minimize antioxidant loss. Interestingly, researchers found that stir-frying and roasting helped retain the most antioxidants, while boiling and steaming caused significant reductions in antioxidant levels. |
Antioxidant-rich dietary supplement -
MAX randomized placebo-controlled trial showed a reduction in cancer risk and all-cause mortality among men taking an antioxidant cocktail low doses of vitamins C and E, beta-carotene, selenium, and zinc but no apparent effect in women, possibly because men tended to have low blood levels of beta-carotene and other vitamins at the beginning of the study.
Age-related eye disease A six-year trial, the Age-Related Eye Disease Study AREDS , found that a combination of vitamin C, vitamin E, beta-carotene, and zinc offered some protection against the development of advanced age-related macular degeneration, but not cataracts, in people who were at high risk of the disease.
However, relatively short trials of lutein supplementation for age-related macular degeneration have yielded conflicting findings. The study found that people taking the vitamins were less likely to progress to late-stage AMD and vision loss.
However, the study authors noted that taking lutein and zeaxanthin alone or vitamin E alone did not have a beneficial effect on these eye conditions. The Selenium and Vitamin E Cancer Prevention Trial SELECT Eye Endpoints Study, which followed 11, men for a mean of five years, did not find that vitamin E and selenium supplements, in combination or alone, protected from age-related cataracts.
It did not find that antioxidant supplements of vitamin E or selenium, alone or in combination, protected against dementia compared with a placebo. Early death A meta-analysis of 68 antioxidant supplement trials found that taking beta-carotene and vitamin A and E supplements increased the risk of dying.
It was also difficult to compare interventions because the types of supplements, the dosages taken, and the length of time they were taken varied widely. The same authors conducted another systematic review of 78 randomized clinical trials on antioxidant supplements including beta-carotene, vitamin A, vitamin C, vitamin E, and selenium alone or in combination.
The study found that both people who were healthy and those with diseases taking beta-carotene and vitamin E supplements had a higher rate of death. The duration of the studies varied widely from one month to 12 years, with varying dosages.
The first inkling came in a large trial of beta-carotene conducted among men in Finland who were heavy smokers, and therefore at high risk for developing lung cancer.
The trial was stopped early when researchers saw a significant increase in lung cancer among those taking the supplement compared to those taking the placebo. Again, an increase in lung cancer was seen in the supplement group. MAX trial, rates of skin cancer were higher in women who were assigned to take vitamin C, vitamin E, beta-carotene, selenium, and zinc.
These results came from the Selenium and Vitamin E Cancer Prevention Trial SELECT that followed 35, men for up to 12 years. References National Center for Complementary and Integrative Health NCCIH.

Medically reviewed by Debra Rose Wilson, Ph. Can figs be beneficial to our health? Traffic-related air pollution TRAP is one of the most concerning sources of air pollution for human exposure and health. Until TRAP levels can be significantly reduced on a global scale, there is a need for effective shorter-term strategies to prevent the adverse health effects of TRAP.
A growing number of studies suggest that increasing antioxidant intake, through diet or supplementation, may reduce this burden of disease. In this paper, we conducted a non-systematic literature review to assess the available evidence on antioxidant-rich diets and antioxidant supplements as a strategy to mitigate adverse health effects of TRAP in human subjects.
We identified 11 studies that fit our inclusion criteria; 3 of which investigated antioxidant-rich diets and 8 of which investigated antioxidant supplements. It is also thought antioxidants and other protective constituents from vegetables, legumes and fruit need to be consumed regularly from early life to be effective.
