The body generates free radicals as the inevitable byproducts of turning food into energy. Free radicals are also formed after exercising or exposure to cigarette smoke, air pollution, and sunlight.

Free radicals come in many shapes, sizes, and chemical configurations. What they all share is a voracious appetite for electrons, stealing them from any nearby substances that will yield them. Free radical damage can change the instructions coded in a strand of DNA.

It can make a circulating low-density lipoprotein LDL, sometimes called bad cholesterol molecule more likely to get trapped in an artery wall.

An excessive chronic amount of free radicals in the body causes a condition called oxidative stress, which may damage cells and lead to chronic diseases. The body, long used to this relentless attack, makes many molecules that quench free radicals as surely as water douses fire. We also extract free-radical fighters from food.

They are also involved in mechanisms that repair DNA and maintain the health of cells. There are hundreds, probably thousands, of different substances that can act as antioxidants. The most familiar ones are vitamin C , vitamin E , beta-carotene , and other related carotenoids, along with the minerals selenium and manganese.

Most are naturally occurring, and their presence in food is likely to prevent oxidation or to serve as a natural defense against the local environment. It is really a chemical property, namely, the ability to act as an electron donor.

Some substances that act as antioxidants in one situation may be pro-oxidants—electron grabbers—in a different situation.

Another big misconception is that antioxidants are interchangeable. Each one has unique chemical behaviors and biological properties. 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.

Artichokes are also a good source of dietary fiber, minerals, and antioxidants. In fact, according to the FRAP analysis, artichokes have up to 4. Additionally, artichokes are particularly rich in chlorogenic acid, a type of antioxidant.

Artichoke is a good source of Vitamin C , potassium , and inulin — a type of prebiotic fiber. It was shown to have strong anti-inflammatory and antimicrobial properties with its antioxidant components, such as vitamin C, hydroxycinnamic acids, polyphenols, and flavonoids.

In fact, eating one artichoke can provide you with 25 percent of the suggested daily intake of vitamin C, which can lower your risk of developing lung cancer, breast cancer, and colon cancer. When you boil artichokes, their antioxidants increase by eight times, and with steaming, you can raise their antioxidants by 15 times.

While some cooking methods can increase the antioxidant content of artichokes, some, like frying them, can decrease their content. Beetroots, also called beets, refer to the roots of a vegetable known as Beta vulgaris. They generally have a mild taste and are a great source of many vitamins and minerals, such as fiber, potassium, iron, folate, and antioxidants.

Count beetroots in foods that are high in antioxidants, as they are one of the best and most rich sources of antioxidants and anti-inflammatory polyphenols.

In the FRAP analysis, beetroots are said to have up to 1. Plus, beetroots are abundant in betalains and polyphenols that give them purple or reddish coloring. Beetroots offer a wide range of health benefits when added to your everyday diet.

They can lower your inflammation levels, enhance your cognition, improve blood pressure, and vastly decrease your risk of developing several types of cancer.

According to a study, beetroots are scientifically proven to improve sports performance if you happen to be a sports athlete [ 8 ]. We know nuts have many calories and dietary fats, but they still offer a wide range of health benefits. In fact, regular consumption of nuts can lower your risk of developing chronic conditions, including cardiovascular disease, certain types of cancer, gallstones, obesity, and type 2 diabetes [ 9 ].

Nuts have health benefits because of their contents of different carotenoids, phytosterols, plant steroids, and ellagic acids with potent antioxidant properties.

Among the variety of nuts, tree nuts, walnuts, pecans and chestnuts are the ones with the highest contents of antioxidants. Moreover, walnuts and pecans have shown a higher ability to scavenge free radicals. Walnuts are recorded to have 20 mmol antioxidants per grams, which is commonly found in walnut pellicles.

They are loaded with antioxidants, plus they are low in sodium and sugar. Not only that, walnuts are also high in omega-3 fatty acids compared to other kinds of nuts.

Adding walnuts to your snack may help in making you feel full throughout the day. There are also many antioxidant creams on the market that can help to improve the appearance of your skin. These creams are packed with antioxidants and they can help protect your skin from damage.
