Antioxidants are found in certain foods and may prevent some of the damage caused by free radicals by neutralising them. These include the nutrient antioxidants, vitamins A, C and E, and the minerals copper, zinc and selenium. Other dietary food compounds, such as the phytochemicals in plants, are believed to have greater antioxidant effects than vitamins or minerals.

By lowering LDL cholesterol levels, anthocyanins may help prevent heart disease. Although strawberries are an ingredient in some baked goods, these products are rarely healthful and are not a good choice for people trying to lose weight. Red cabbage, like strawberries and red kale , contains anthocyanins.

In addition to giving the vegetable its red color, this group of antioxidants helps promote heart health, prevent cancer, and reduce inflammation. According to one study , anthocyanins have the following health benefits:. However, more research is still necessary to determine the health effects of eating red cabbage.

A person can eat red cabbage as part of a salad or as a cooked vegetable. Raspberries are an excellent source of many antioxidants. They also contain manganese, vitamin C , and dietary fiber. Evidence suggests that the antioxidants present in raspberries may help destroy certain cancer cells.

For example, in one laboratory study , researchers found that the antioxidants and some other compounds in raspberries helped kill breast, colon, and stomach cancer cells in a test tube.

A more recent review of studies showed that the compounds in black raspberries might slow the progression of cancerous tumors. However, most of the research on raspberries has involved experiments in test tubes.

Consequently, researchers need to carry out studies involving people to judge the effectiveness of eating raspberries in preventing disease.

Beans are an excellent source of protein and dietary fiber. Some beans, such as pinto beans, are also high in antioxidants. Pinto beans contain a plant flavonoid called kaempferol, which may help suppress cancer cell growth and reduce inflammation.

Several studies link kaempferol to the suppression of specific cancers, including:. Despite these promising studies, researchers do not know much about the antioxidant effect of kaempferol in humans.

To date, they have primarily carried out studies in animals and test tubes. However, as beans have several potential health benefits, it is a good idea for people to include them as part of their regular diet.

Purple and red grape varieties contain vitamin C, selenium , and antioxidants. Two of the antioxidants that occur in grapes, namely anthocyanin and proanthocyanin, may help protect a person from heart disease or cancer.

However, there is a need for additional research to show the exact effects that eating grapes has on heart health and cancer risk. Spinach is a green, leafy vegetable full of vitamins, minerals, and antioxidants.

It is low in calories, making it an excellent choice as an addition to salads and entrees. Zeaxanthin and lutein are two of the antioxidants in spinach that may promote eye health. They help prevent damage from ultraviolet UV rays and other harmful light waves.

A review of studies on lutein and zeaxanthin noted that lots of studies have investigated their role in age-related macular degeneration. The authors also suggested how people could get more of these antioxidants in their diets, naming dark leafy greens, eggs, and pistachios as sources.

Beets are vegetables that contain antioxidants belonging to a class of pigments called betalains. Betalains may help prevent colon cancer and digestive issues. Beets are also a source of dietary fiber, iron, folate , and potassium.

These substances may help with suppressing inflammation. One review noted that betalains show promise for reducing free radicals and helping prevent cancer. However, research has not yet determined the effectiveness of eating beets for these benefits. Kale is rich in vitamins A, C, and K, and it contains several antioxidants.

It is a popular health food and hardy winter vegetable, common in many northern regions. Anthocyanins are antioxidants that are readily available in a variety of fruits and vegetables. They are responsible for the color of these foods, from vibrant red to blue.

With their velvety red skin and floral aroma, raspberries are loaded with protective antioxidants that ward off disease.

According to a study published in Antioxidants , the major antioxidants present in raspberries include anthocyanins, ellagitannins and vitamin C.

The researchers revealed that these compounds may combat oxidative stress and inflammation that promote the development of diseases like cancer. In just 3. Consider whipping up this Muesli with Raspberries when you are in need of an antioxidant boost.

Whether you are looking to protect your cells from harmful free radicals, find relief from chronic inflammation, or aid in disease management, antioxidants are powerful compounds that can significantly improve your health. Although red and purple fruits like blueberries, pomegranates, tart cherries, blackberries, goji berries and raspberries have the highest quantities, antioxidants are also abundant in various plant foods.

From fruits to vegetables, nuts and legumes, you can obtain all the antioxidants you need when you consume a balanced diet. Use limited data to select advertising. Create profiles for personalised advertising. Use profiles to select personalised advertising. Create profiles to personalise content.

They almost certainly evolved as parts of elaborate networks, with each different substance or family of substances playing slightly different roles. This means that no single substance can do the work of the whole crowd.

Antioxidants came to public attention in the s, when scientists began to understand that free radical damage was involved in the early stages of artery-clogging atherosclerosis.

It was also linked to cancer , vision loss, and a host of other chronic conditions. Some studies showed that people with low intakes of antioxidant-rich fruits and vegetables were at greater risk for developing these chronic conditions than were people who ate plenty of those foods.

Clinical trials began testing the impact of single substances in supplement form, especially beta-carotene and vitamin E, as weapons against chronic diseases. Supplement makers touted the disease-fighting properties of all sorts of antioxidants. The research results were mixed, but most did not find the hoped-for benefits.

Antioxidants are still added to breakfast cereals, sports bars, energy drinks, and other processed foods , and they are promoted as additives that can prevent heart disease, cancer, cataracts, memory loss, and other conditions.

Randomized placebo-controlled trials, which can provide the strongest evidence, offer little support that taking vitamin C, vitamin E, beta-carotene, or other single antioxidants provides substantial protection against heart disease, cancer, or other chronic conditions.

The results of the largest trials have been mostly negative. A modest effect of vitamin E has been found in some studies but more research is needed. A study from the Journal of Respiratory Research found that different isoforms of vitamin E called tocopherols had opposing effects on lung function.

Lung function was tested using spirometric parameters: higher parameters are indicative of increased lung function, while lower parameters are indicative of decreased lung function. The study found that higher serum levels of alpha-tocopherol were associated with higher spirometric parameters and that high serum levels of gamma-tocopherol were associated with lower spirometric parameters.

Though the study was observational in nature, it confirmed the mechanistic pathway of alpha- and gamma-tocopherol in mice studies. When it comes to cancer prevention, the picture remains inconclusive for antioxidant supplements. Few trials have gone on long enough to provide an adequate test for cancer.

High-dose antioxidant supplements can also interfere with medicines. Vitamin E supplements can have a blood-thinning effect and increase the risk of bleeding in people who are already taking blood-thinning medicines. Some studies have suggested that taking antioxidant supplements during cancer treatment might interfere with the effectiveness of the treatment.

Inform your doctor if starting supplements of any kind. One possible reason why many studies on antioxidant supplements do not show a health benefit is because antioxidants tend to work best in combination with other nutrients, plant chemicals, and even other antioxidants.

For example, a cup of fresh strawberries contains about 80 mg of vitamin C, a nutrient classified as having high antioxidant activity.

Polyphenols also have many other chemical properties besides their ability to serve as antioxidants. There is a question if a nutrient with antioxidant activity can cause the opposite effect with pro-oxidant activity if too much is taken.

This is why using an antioxidant supplement with a single isolated substance may not be an effective strategy for everyone. Differences in the amount and type of antioxidants in foods versus those in supplements might also influence their effects.

For example, there are eight chemical forms of vitamin E present in foods. However, vitamin E supplements typically only include one form, alpha-tocopherol. Epidemiological prospective studies show that higher intakes of antioxidant-rich fruits, vegetables, and legumes are associated with a lower risk of chronic oxidative stress-related diseases like cardiovascular diseases , cancer, and deaths from all causes.

The following are nutrients with antioxidant activity and the foods in which they are found:. Excessive free radicals contribute to chronic diseases including cancer, heart disease, cognitive decline, and vision loss. Keep in mind that most of the trials conducted have had fundamental limitations due to their relatively short duration and inclusion of people with existing disease.

At the same time, abundant evidence suggests that eating whole in fruits , vegetables , and whole grains —all rich in networks of naturally occurring antioxidants and their helper molecules—provides protection against many scourges of aging.

Search for:. Home Nutrition News What Should I Eat? 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.
