In , a rating tool called the Oxygen Radical Absorbance Capacity ORAC was created by scientists from the National Institute on Aging and the United States Department of Agriculture USDA.

It was used to measure the antioxidant capacity of foods. The USDA provided an ORAC database on its website highlighting foods with high ORAC scores, including cocoa, berries, spices, and legumes.

Blueberries and other foods topping the list were heavily promoted in the popular press as disease-fighters even if the science was weak, from cancer to brain health to heart disease. 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.

Free radicals can increase the risk of inflammation and various health issues. The sources of antioxidants can be natural or artificial. Certain plant-based foods are thought to be rich in antioxidants. Plant-based antioxidants are a kind of phytonutrient, or plant-based nutrient.

The body also produces some antioxidants, known as endogenous antioxidants. Antioxidants that come from outside the body are called exogenous. Free radicals are waste substances produced by cells as the body processes food and reacts to the environment.

If the body cannot process and remove free radicals efficiently, oxidative stress can result. This can harm cells and body function. Free radicals are also known as reactive oxygen species ROS. Factors that increase the production of free radicals in the body can be internal, such as inflammation , or external, for example, pollution, UV exposure, and cigarette smoke.

Antioxidants are said to help neutralize free radicals in our bodies, and this is thought to boost overall health. Antioxidants can protect against the cell damage that free radicals cause, known as oxidative stress.

Activities and processes that can lead to oxidative stress include :. The damage caused by oxidative stress has been linked to cancer, atherosclerosis , and vision loss. It is thought that the free radicals cause changes in the cells that lead to these and possibly other conditions.

Other research has indicated that antioxidant supplements may help reduce vision loss due to age-related macular degeneration in older people. Overall, however, there is a lack of evidence that a higher intake of specific antioxidants can reduce the risk of disease. In most cases, results have tended to show no benefit, or a detrimental effect, or they have been conflicting.

There are thought to be hundreds and possibly thousands of substances that can act as antioxidants. 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.

Goji berries and many other food products that contain antioxidants are available to purchase online. 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. Consuming an antioxidant-rich diet can help fight free radicals and lower the chance of developing several chronic illnesses.
