How to Boost Your Antioxidant NetworkNatural antioxidant sources -
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. 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.
Lutein, found in spinach and corn, has been linked to a lower incidence of eye lens degeneration and associated vision loss in the elderly. Research also suggests that dietary lutein may improve memory and prevent cognitive decline. Studies show that flavonoid-rich foods prevent some diseases, including metabolic-related diseases and cancer.
Apples, grapes, citrus fruits, berries, tea, onions, olive oil and red wine are the most common sources of flavonoids. Plant foods are rich sources of antioxidants. They are most abundant in fruits and vegetables, as well as other foods including nuts, wholegrains and some meats, poultry and fish.
Good sources of specific antioxidants include:. There is increasing evidence that antioxidants are more effective when obtained from whole foods, rather than isolated from a food and presented in tablet form. Research shows that some vitamin supplements can increase our cancer risk.
For example, vitamin A beta-carotene has been associated with a reduced risk of certain cancers, but an increase in others — such as lung cancer in smokers if vitamin A is purified from foodstuffs. A study examining the effects of vitamin E found that it did not offer the same benefits when taken as a supplement.
A well-balanced diet, which includes consuming antioxidants from whole foods, is best. If you need to take a supplement, seek advice from your doctor or dietitian and choose supplements that contain all nutrients at the recommended levels.
Research is divided over whether antioxidant supplements offer the same health benefits as antioxidants in foods. To achieve a healthy and well-balanced diet , it is recommended we eat a wide variety from the main 5 food groups every day:.
To meet your nutritional needs, as a minimum try to consume a serve of fruit and vegetables daily. Although serving sizes vary depending on gender, age and stage of life, this is roughly a medium-sized piece of fruit or a half-cup of cooked vegetables.
The Australian Dietary Guidelines External Link has more information on recommended servings and portions for specific ages, life stage and gender. 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.

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. 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.
Several orange vegetables contain vitamin A and other nutrients. These vegetables contain large amounts of phytochemicals that can help with heart disease and cancer prevention. Some examples of orange vegetables with high antioxidant levels include:.
There is limited evidence to suggest how best to serve orange vegetables. Often, people cook them, but a person can eat some varieties, such as carrots, raw as a snack or part of a salad. There are many common foods that people can eat to increase the number of antioxidants that they consume.
The antioxidants in these foods may help promote heart and eye health, prevent cancer, and protect against other common diseases that scientists associate with harmful free radicals. However, researchers still need to understand the extent to which each of these foods helps people acquire higher levels of antioxidants.
They also need to determine how effective each is in disease prevention. Free radicals are unstable atoms that can cause damage to cells and lead to illnesses and the aging process.
