About oxidation Antioxidants and free radicals The effect of free radicals Disease-fighting antioxidants Sources of antioxidants Vitamin supplements and antioxidants Dietary recommendations for antioxidants Where to get help. About oxidation The process of oxidation in the human body damages cell membranes and other structures, including cellular proteins, lipids and DNA. Antioxidants and free radicals Antioxidants are found in certain foods and may prevent some of the damage caused by free radicals by neutralising them. Disease-fighting antioxidants A diet high in antioxidants may reduce the risk of many diseases including heart disease and certain cancers. Sources of antioxidants Plant foods are rich sources of antioxidants. However, 20 years later the USDA retracted the information and removed the database after determining that antioxidants have many functions, not all of which are related to free radical activity. Although this was not a primary endpoint for the trial, it nevertheless represents an important outcome. In the Heart Outcomes Prevention Evaluation HOPE trial, the rates of major cardiovascular events were essentially the same in the vitamin E A recent trial of vitamin E in Israel, for example, showed a marked reduction in coronary heart disease among people with type 2 diabetes who have a common genetic predisposition for greater oxidative stress. In the Supplementation en Vitamines et Mineraux Antioxydants SU. MAX study, 13, French men and women took a single daily capsule that contained mg vitamin C, 30 mg vitamin E, 6 mg beta-carotene, mcg selenium, and 20 mg zinc, or a placebo, for seven and a half years. The vitamins had no effect on overall rates of cardiovascular disease. Lung disease A study from the Journal of Respiratory Research found that different isoforms of vitamin E called tocopherols had opposing effects on lung function. Cancer When it comes to cancer prevention, the picture remains inconclusive for antioxidant supplements. 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.

What are antioxidants? Should you get antioxidants from food or take supplements? What are the best antioxidant foods? You can get the following antioxidants from these food sources: Vitamin A — liver, sweet potatoes, carrots, milk and egg yolks Vitamin C — broccoli, Brussels sprouts, cauliflower Vitamin E — almonds, avocado, leafy greens Carotenoids — apricots, asparagus, broccoli Zinc — beef, oysters, pumpkin seeds Selenium — Brazil nuts, fish, shellfish Beta-carotene — carrots, pumpkin, sweet potato, spinach Lycopene — tomato, watermelon, grapefruit. Are there any benefits to taking antioxidant supplements? Antioxidant foods for healthy glowing skin: Eat your way to better looking skin I have been advised to take antioxidant supplements. Which ones are best? What happens if you take too many antioxidant supplements? If you take antioxidant supplements in high doses, you could damage your body. Some antioxidant supplements may: 1. Reduce your exercise performance Taking too many antioxidant supplements, especially vitamins C and E can interfere with how your body adapts to exercise and even reduce some of the health benefits of exercise. |
| Latest articles | Other antioxidants include lycopene, carotenoids, lutein, zeaxanthin, anthocyanins , quercetin, glutathione and flavonoids like rutin. As described above, the single most important benefit of antioxidants is counteracting free radicals found inside every human body, which are very destructive to things like tissue and cells. Free radicals are responsible for contributing to many health issues and have connections to such diseases as cancer and premature aging of the skin or eyes. The body uses antioxidants to prevent itself from the damage caused by oxygen. 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. Contact a health care provider if you have questions about your health.

Antioxidant supplements -
Not all free radicals are damaging , and some are even used to attack viruses or bacteria to protect us from harm. However, others can damage cells and contribute to conditions such as heart disease and some cancers. Most of us can get all the nutrients we need from food, rather than taking supplements.
Vegetables and fruit tend to be packed full of antioxidants. Eating a wide variety of them can help ensure you get a diverse range of different antioxidants to optimise your health. There are hundreds of antioxidants in not only fruit and vegetables, but nuts, seeds, olive oil and wholegrains.
The Australian Dietary Guidelines outline the types of foods you should be eating to reduce your risk of diet-related conditions and chronic diseases.
In some cases, your doctor may recommend you take antioxidant supplements if your diet is inadequate. The only reason to take supplements is if you have a deficiency. For example, vegetarians might need iron or vitamin B12, or people with osteoporosis might need extra calcium and vitamin D.
If you follow a healthy balanced diet, and you have no vitamin deficiencies, adding antioxidant supplements is unlikely to make any difference to your health.
Rigorous scientific studies involving more than , people tested whether antioxidant supplements played a role in preventing chronic diseases, like cardiovascular diseases, cancer, and cataracts. In most instances, supplementing with antioxidants did not reduce the risks of developing these diseases.
In fact, some supplements can be toxic in large doses, interact with other medications, and can actually increase the risk of developing certain diseases. There are no current concerns about the levels of antioxidants we consume in food. Antioxidant foods for healthy glowing skin: Eat your way to better looking skin.
You can find antioxidant supplements in different forms, including multivitamins, antioxidant blends, tablets, vitamins, gummies and powders to mix into drinks or sprinkle on foods. Taking too many antioxidant supplements, especially vitamins C and E can interfere with how your body adapts to exercise and even reduce some of the health benefits of exercise.
Studies have even shown that antioxidant supplements may even increase the risk of certain cancers. Some can interfere with cancer treatment medications and therapies so check with your doctor before you start taking any.

The World Health Organisation has classified antioxidant as "possibly carcinogenic to humans" although it considered safe at low levels.
Some people may choose to simply swap foods with BHA added for safer alternatives. Like BHA, TBHQ or antioxidant is a synthetic food additive which helps preserve food products. Similar to BHA, you might find this ingredient if you check out the labels on some common processed snack foods.
Food Standards Australia and New Zealand classifies both antioxidants and as additives most likely to be a problem for people with food allergies or intolerances. Read more about foods that can help reduce stress: The three best healthy stress foods.
Many skincare brands boast the properties of antioxidants in their serums, creams or lotions. This is because of the benefits antioxidants like Vitamin C, Vitamin E, beta-glucans and polyphenols can have for our skin.
Whether the antioxidants make it into our bloodstream is dependant on their molecule type, size and what other ingredients are included to aid in absorption.
Each serum, cream or lotion formulation will differ. Antioxidants — Better Health Channel. 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.

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.
