Antioxicant-packed and juicy, goods are another example of a great antioxidant rich Antioxicant-packed.
As described in an analysis published by the Antiodidant-packed of Agricultural and Food Chemistryone medium-sized fruit contains nearly 6. Multiple studies included in a review published in Phytotherapy Research demonstrated that regular consumption of plums can lead to better cognitive function, bone density and cardiovascular health.
If you want to top up your antioxidant intake, consider making dark chocolate your next snack of choice. Its main ingredient, cocoa powder, is a rich dietary source of flavonoids like catechin, epicatechin and procyanidins. These are compounds that have been shown to lower inflammation levels, improve cardiovascular health and contribute to better immune responses.
According to a review published in the Oxidative Medicine and Cellular Longevitycocoa consumption may also have a positive impact on insulin resistance, cognitive function and mood.
To get the most benefit, aim for minimally processed chocolate with a high cocoa content. Beetroots are undoubtedly one of the best antioxidant rich foods you can include in your diet. There are multiple health benefits associated with their consumption.
These root vegetables provide a significant amount of nitrates, compounds that have a direct impact on the functioning of our cardiovascular system. Beetroot juice also contains a high amount of antioxidant and anti-inflammatory polyphenols.
These vegetables are particularly abundant in betalains, polyphenols which give them their characteristic purple coloring. According to a review published in the Nutrients journal, regular beetroot and beetroot juice consumption can lead to lower inflammation levels, better cognition, improved blood pressure and a vastly reduced risk of developing several types of cancer.
A review published in Sports Medicine also suggests that there is some evidence that beetroot juice may have a significant impact on the sports performance among athletes.
Green leafy vegetables are the cornerstone of a healthy diet. Kale, spinach, watercress, cabbage or lettuce are not only very low in calories and dietary fats, they also provide a significant amount of fiber, vitamins and minerals. Spinach is a great example of a green leafy vegetable with a high antioxidant content.
Research published in Food and Function showed that regular consumption of spinach may lead to a reduced risk of developing obesity, type 2 diabetes, atherosclerosis and several types of cancer. It contains two powerful carotenoid antioxidants: lutein and zeaxanthin.
And according to a review published in the Nutrition Reviews journal, lutein and zeaxanthin can absorb damaging blue light that enters the eye, protecting this vital organ from degeneration. Artichoke is a vegetable that has a similar taste to asparagus and is most commonly found in the Mediterranean diet.
They are a rich source of inulin, a type of a prebiotic fiber, as well as potassium and vitamin C. According to a review recently published in the International Journal of Molecular Sciencesartichokes have been shown to possess strong anti-inflammatory and antimicrobial properties.
These characteristically bulky vegetables are also a rich source of antioxidants like vitamin C, hydroxycinnamic acids, polyphenols and flavonoids. However, many of these examples of these staples provide a high amount of polyphenols with strong free radical scavenging abilities.
According to an analysis published in the Journal of Food Scienceyellow pea, green pea, chickpea, soybean, common bean, lentils, and red kidney bean are the lentils with the highest antioxidant abilities. Although nuts are very high in calories and dietary fats, they have many health benefits.
A review published in Nutrients revealed that regular nut consumption can vastly decrease the risk of developing a host of chronic conditions, including cardiovascular disease, type 2 diabetes, obesity, gallstones and certain types of cancer. One of the reasons behind this positive impact is that these food staples contain many different carotenoids, phytosterols plant steroids and ellagic acids with strong antioxidant properties.
And according to a comparison published in the Food Science and Technology journal, walnuts and pecans tend to show the highest ability to scavenge free radicals. According to a review published by the Antioxidants journal, oats contain high levels of many important antioxidants, including beta-carotene, polyphenols, chlorophyll and flavonoids.
They have been shown to excel at scavenging free radicals, activating cell repair mechanisms and protecting against cell damage, as described in the Foods journal. The Nutrition Source.

: Antioxidant-packed foods| High-Antioxidant Foods, Herbs & Supplements: Why You Need More | To understand antioxidants, it helps to know a bit about free radicals. Antioxidants are vitamins and other nutrients found in plant-based foods like fruits, vegetables, legumes, and whole grains that prevent or slow damage to cells in your body caused by these free radicals. Keep in mind that antioxidants aren't substances themselves—rather, the term "antioxidant" refers to a chemical property exhibited by hundreds of different and non-interchangeable substances. Many of these we're highly familiar with, like vitamin C , vitamin E, selenium, and beta-carotene. Others are less familiar: polyphenols, flavonoids, lipoic acid, glutathione, and so on. Most antioxidants occur naturally; they exist in foods to inhibit oxidation and protect against toxins in the local environment. So if you're looking to up your antioxidant intake, you're in good shape—and luckily, there are plenty of delicious ingredients options for you to choose from. Here are the top antioxidant-rich foods, according to registered dietitians. FYI, none mention any pricey matcha-goji-turmeric-tonic wellness bowls. Kidney beans and other beans are rich sources of antioxidants. Anthocyanins have been shown to reduce the risk of diabetes, heart disease, and cancer. Believe it or not, artichoke hearts are one of the most antioxidant-rich vegetables, full of polyphenols like chlorogenic acid also found in coffee which may help the body better metabolize glucose and blood lipids. Pecans are rich in the antioxidant vitamin E and have been shown to help lower levels of LDL bad cholesterol in the body, improving heart health. Pecans are also high in monounsaturated fat and contain a decent amount of fiber , making them one of the healthiest nuts you can eat. She recommends topping air-popped popcorn with sea salt, rosemary, and thyme. According to Silberman, pumpkin seeds are a great source of protein, fiber, and antioxidants like vitamin E and carotenoids. For the ultimate antioxidant-rich snack, Silberman says to try sliced apples topped with peanut butter, chia seeds, and cinnamon. Khoo HE, Azlan A, Tang ST, Lim SM.

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. 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. Ascorbic acid, also known as vitamin C, is a water-soluble vitamin, which means that it dissolves in water. For this reason, cooking food in water with methods like boiling can cause a huge reduction in antioxidant content. However, not all compounds on the antioxidants list are affected in the same way by cooking. For example, one study found that consuming tomatoes cooked in olive oil significantly enhanced levels of lycopene in the blood by up to 82 percent compared to a control group. Similarly, another study in British Journal of Nutrition showed that stir-frying carrots significantly boosted the absorption of beta-carotene. For example, because during exercise oxygen consumption can increase by a factor of more than 10, taking high doses of antioxidants might interfere with proper exercise recovery. When it comes to protection against things like cancer or heart disease, overall the medical literature seems conflicting. Although some studies found a positive relationship between antioxidant supplementation and risk reduction, others have not found such positive effects.

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.

Eat Empowered Fuel your body and mind with nutrient-dense foods to look and feel amazing. 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.

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. But the good news is that there is a solution to oxidative stress. And it requires the consumption of—you guessed it— antioxidants! One way to ensure you are getting enough antioxidants in your diet is to consume a variety of delicious fruits. Below are six of the best antioxidant-rich fruits that can help you ward off oxidative stress and inflammation. Blueberries take the blue ribbon as one of the top antioxidant-rich fruits on the list. And rightfully so! These remarkable berries contain up to 9 millimoles of antioxidants in a single 3. But where does this tiny fruit store such a large amount of antioxidants? The answer is their deep blue outer skin: the antioxidants responsible for their distinctive dark-blue hue are powerful, anti-inflammatory compounds called anthocyanins. A review published in Advances in Nutrition found that people who regularly consume anthocyanin-rich blueberries have a lower risk of cardiovascular disease and type 2 diabetes, along with improved weight management and brain functioning. What better way to reap the many health benefits associated with blueberries than by enjoying this Blueberry Baked Oatmeal? Slice into a pomegranate's smooth, thick skin, and you will find incredible chambers of juicy, ruby-red seeds aka arils that burst with flavor and antioxidants. A review published in Foods reported that pomegranates have potent antioxidant and anti-inflammatory properties that can lower several inflammatory biomarkers associated with chronic disease. Specifically, the researchers concluded that pomegranates might protect against obesity, cardiovascular disease, diabetes and certain types of cancer. These health benefits are primarily due to an antioxidant known as punicalagin. According to the Antioxidant Food Database, pomegranates contain up to 9 mmol of antioxidants per 3. These tart stone fruits contain a wide array of beneficial compounds that have been proven to boost your health. In fact, a review published in Nutrients —that included 20 studies on tart cherries—found that their high antioxidant concentration is associated with reduced inflammation and oxidative stress. But the cherry on top of the cake is that they've also been shown to improve sleep , blood pressure and arthritic pain. The compounds responsible for these impressive benefits include polyphenols, melatonin, carotenoids and vitamins E and C. According to the Antioxidant Food Database, tart cherries contain up to 7 mmol of antioxidants per 3. You can include this nutrient-packed fruit in your diet by preparing this Anti-Inflammatory Cherry-Spinach Smoothie. Though commonly called berries, botanically, blackberries are actually a cluster of single-seeded drupelets filled with protective plant compounds. In a study published in Foods , the researchers found that blackberries contain several antioxidant-rich compounds that can inhibit the release of pro-inflammatory molecules linked to inflammatory conditions. Of the antioxidants present in blackberries, anthocyanins and terpenoids are the most prominent ones. According to the Antioxidant Food Database, 3.

Many healthful foods contain antioxidants. If a person consumes some or all of these foods regularly, they may increase their antioxidant levels, potentially helping them prevent the damage that doctors associate with oxidative stress.
In this article, we list some of the most healthful foods that a person can eat to boost the antioxidants in their diet. Blueberries are rich in nutrients while also being low in calories. A study showed that wild blueberries contain a large number of antioxidants.
Studies on blueberries have shown that these fruits have beneficial effects as a result of their antioxidant content. For example, the authors of a review of animal studies concluded that antioxidants in blueberries might have medicinal uses for neurological conditions, including those that relate to aging.
A review examined the anthocyanins that occur naturally in blueberries and other plant materials. Anthocyanins belong to a group of chemicals that have antioxidant and anti-inflammatory actions.
They are responsible for many of the bright colors of fruits and vegetables. Good quality dark chocolate has high levels of nutrients and antioxidants. Researchers have linked dark chocolate to a range of potential health benefits, including:.
One review of 10 studies involving close to participants showed that dark chocolate helps reduce both upper and lower blood pressure measurements. The authors noted, however, that future research needs to determine how much dark chocolate a person should eat for these benefits and investigate its effect on other metabolic conditions.
Artichokes provide lots of nutrients and antioxidants. One study looking at the medicinal use of artichokes over time noted that artichoke consumption can be good for gut, liver, and heart health.
Another study showed that chemicals in artichokes had an antioxidant effect on LDL cholesterol in laboratory tests. How people prepare artichokes makes a difference to their antioxidant levels. One study compared boiling, frying, and steaming to see how each affected the antioxidant levels.
The results showed that steaming increased the effectiveness of the antioxidants by 15 times while boiling increased it eightfold. Researchers believe the reason for this is that boiling and steaming break down the cell walls, making the antioxidants more accessible.
One study showed that the body can absorb antioxidants from pecans, increasing their levels in the blood. It also found that eating raw pecans helps lower the blood levels of oxidized LDL cholesterol, which may mean that these nuts help prevent heart disease.
Strawberries are rich in antioxidants, vitamins , and minerals. Strawberries owe their red color to anthocyanins, which have antioxidant powers.
A review showed that taking anthocyanin supplements reduced the levels of LDL cholesterol in participants with high cholesterol.
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.
