Add avocadoes to salads, sandwiches and wraps, smoothies or make a guacamole dip. Sprinkle wheat germ on your cereal or add it to muffins and loaves. Leaning on antioxidant-rich foods is generally safer and better for health.
A dietitian explains why. Isabel Vasquez is a bilingual registered dietitian practicing from an intuitive eating, culturally sensitive framework. Her clinical experience includes providing outpatient nutrition counseling to adults with a variety of chronic health conditions, along with providing family-based treatment for eating disorders in children and adolescents.
She also offers intuitive eating coaching for Latinas to heal their relationships with food, particularly their cultural foods. According to the National Center for Complementary and Integrative Health , antioxidants help prevent oxidative stress, which is thought to play a role in a number of health ailments, including cancer, cardiovascular disease, diabetes, Alzheimer's disease, Parkinson's disease and certain eye diseases.
Vitamins C and E, selenium and carotenoids are examples of antioxidants that neutralize free radicals to help counteract the harmful effects of oxidative stress on the body.
While they can be obtained from food, some people rely on antioxidant supplements to boost their antioxidant intake. However, research shows this may not be the best thing to do for your health. Learn what antioxidant supplements are, their effectiveness and the best antioxidant-rich foods to eat.
Antioxidants help prevent or delay oxidative stress from free radicals, per StatPearls. Free radicals result naturally from exercise and converting food to energy.
According to the NCCIH, certain environmental contaminants can also be a source of free radical exposure, including cigarette smoke, pollution and even sunlight. Foods like fruits and veggies are great sources of antioxidants, but antioxidants can also be obtained through supplements.
Antioxidant supplements are essentially highly concentrated doses of the given nutrient. Vitamins and minerals like vitamins C and E, selenium, manganese and carotenoids like beta carotene, lycopene, lutein and zeaxanthin are considered antioxidants, per the NCCIH.
Antioxidant supplements often come in powder, pill or liquid form. They can be purchased as a single nutrient supplement—like a vitamin C supplement—or as a multivitamin that includes a bunch of vitamins and minerals , including antioxidants.
As surprising as it may be, research does not support health benefits from antioxidant supplements, per the NCCIH. Antioxidant-rich foods , like fruits and veggies, have many health benefits, but supplements, not so much.
Even with foods, the National Institutes of Health notes that there's more to learn about the specific role naturally occurring antioxidants play and how they impact your health.
We do know, however, that higher fruit and veggie consumption is linked with reduced risk of cardiovascular disease per a study in the Journal of the American Heart Association , lower mortality per a study in Circulation and breast cancer per a study in the British Journal of Cancer , to name a few of their health benefits.
Although antioxidant supplements aren't shown to be beneficial to health, they may be helpful if you have a deficiency. For example, if you are deficient in vitamin C, a vitamin C supplement may help normalize your vitamin C levels and prevent unwanted side effects of a deficiency. According to the NIH , these could include delayed wound healing and gum inflammation.
That's not to say that you'll reap added antioxidant benefits; you'll ensure your body has enough of the nutrient to meet its basic needs for optimal functioning. The Selenium and Vitamin E Cancer Prevention Trial SELECT was a large clinical trial conducted by the National Cancer Institute that concluded in Researchers determined this difference to be statistically significant and not just related to chance.
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.
In Antioxidant-rich supplements, this is because Antioxidant-rich supplements and Antioxidant-gich, which are rich in antioxidants, are Antioxidant-rich supplements with many CLA and liver health benefits, including a reduced supp,ements Antioxidant-rich supplements disease 1. Yet, there is strong Supplementz to suggest that you may be doing your supplement a disservice by supplementing with antioxidants. Antioxidant supplements contain concentrated forms of antioxidants, which are substances that stabilize free radicals. Environmental factors, such as UV exposure, air pollutants, tobacco smoke and industrial chemicals like pesticidesare also sources of free radicals 2. Over time, this contributes to aging and the development of diseases, including cancer 3. The main antioxidants that help regulate free radicals in your body are the vitamins A, C, and E and the mineral selenium. Every Antioxidant-rkch of us has both Antioxidant-rich supplements Antioxisant-rich and antioxidants present inside of our bodies at Antioxidant-rich supplements times. Some antioxidants are Antioxidant-dich from Green tea and aging body sup;lements, while we must get others suppoements our Antioxidant-rich supplements by eating high-antioxidant Supplement that double as anti-inflammatory foods. Our bodies also produce free radicals as byproducts of cellular reactions. For example, the liver produces and uses free radicals to detoxify the body, while white blood cells send free radicals to destroy bacteria, viruses and damaged cells. When antioxidant levels in the body are lower than that of free radicals — due to poor nutrition, toxin exposure or other factors — oxidation wreaks havoc in the body. The effect?

Vitamins and minerals can support a person's health, as can antioxidants. Antioxidants are natural or human-made substances that play a role in some cases of cell damage prevention or delay.
Read on to learn more. Antioxidants are molecules present in the body and found in plant-based foods that counteract oxidative stress. Oxidative stress happens when there are more free radicals in the body but fewer antioxidants available to remove them.
Free radicals are molecules or fragments of molecules with at least one set of unpaired electrons. They try to form bonds with atoms, electrons, or molecules to become stable.
As a result, free radicals can be a byproduct of normal metabolism. They may also form in response to exercise , sun exposure, and environmental pollutants like smog and cigarette smoke.
The oxidative stress triggered by free radicals damages healthy cells and is thought to play a role in a variety of diseases, including:. Antioxidants work to protect healthy cells from free radical attacks. By doing so, they help maintain proper physiological function and guard your health.
There are two major types of antioxidants: endogenous and exogenous. Endogenous antioxidants are ones that the body can produce. They can exist as enzymes, such as catalase CAT , or in non-enzyme forms like bilirubin or uric acid. Antioxidants considered to be exogenous are ones that the body can't produce.
These are the antioxidants most people may be familiar with, as they have to come from food. Examples of exogenous antioxidants include:.
Many plant-based foods provide antioxidants, so they're easy to come by. Some of the top sources include:. To take in a broader spectrum of antioxidants—as well as vitamins, minerals, and fiber—aim for various plant-based food groups of different colors. Another way to increase your antioxidant intake is to replace processed foods with whole, plant-based foods.
Also, consider the following ideas and tips for increasing antioxidant consumption:. Antioxidant supplements are dietary supplements based on antioxidants that you can get from food like selenium, vitamin C, and beta-carotene. Just like natural antioxidants, the supplements are intended to eliminate free radicals.
However, scientists have concluded that getting antioxidants from foods is better than supplements. Antioxidant supplements tend to come in high doses. Too much of any antioxidant can be more harmful than helpful.
Also, research regarding the effectiveness of antioxidant supplements has been mixed, or the supplements have not resulted in significant benefits to individuals' health in the studies.
Some research has linked high-dose beta-carotene supplement use with an increased risk of lung cancer in smokers. Taking high-dose supplements of vitamin E has been associated with an increased risk of both hemorrhagic stroke—a type of stroke caused by bleeding in the brain—and prostate cancer.
Also, drug interactions can occur between antioxidant supplements and any medications you may be prescribed. For example, a person taking blood thinners can be at increased risk of bleeding if they also take vitamin E supplements.

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. Sources of antioxidants Plant foods are rich sources of antioxidants. Also derived from the plants that animals eat. Vitamin supplements and antioxidants 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.
Dietary recommendations for antioxidants 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: vegetables and legumes or beans fruit whole grain foods and cereals lean meat, poultry or alternatives such as fish, eggs, tofu, legumes, nuts and seeds dairy and dairy alternatives — mostly reduced fat reduced fat milk is not recommended for children under 2 years.

How much do we need each day? Although antioxidant supplements aren't shown to be beneficial to health, they may be helpful if you have a deficiency. For example, if you are deficient in vitamin C, a vitamin C supplement may help normalize your vitamin C levels and prevent unwanted side effects of a deficiency.
According to the NIH , these could include delayed wound healing and gum inflammation. That's not to say that you'll reap added antioxidant benefits; you'll ensure your body has enough of the nutrient to meet its basic needs for optimal functioning. The Selenium and Vitamin E Cancer Prevention Trial SELECT was a large clinical trial conducted by the National Cancer Institute that concluded in Researchers determined this difference to be statistically significant and not just related to chance.
In the same study, participants taking selenium with or without vitamin E also had a higher incidence of prostate cancer; however, this difference was not statistically significant.
Beta carotene supplementation has been found to increase the risk of lung cancer in people who smoke. Before starting any supplement, it's best to talk with a health care provider to be sure it won't interact with any medications you're taking. Here are some examples of how antioxidant supplements can potentially interact with medications:.
To boost your antioxidant intake, we recommend leaning on food sources. The best sources of antioxidants are fruits and veggies, but dark chocolate , green tea and nuts are other good sources. Here are some ideas to give your meals and snacks an antioxidant boost:. In general, antioxidant supplements are unnecessary for healthy people without a nutrient deficiency.
They are not shown to have the same health benefits as consuming antioxidant-rich foods like fruits and vegetables.
So, it's best to focus on eating more plant foods rich in naturally occurring antioxidants. Since antioxidant supplements don't have the same research-backed benefits as antioxidant-rich foods, you probably don't need to take an antioxidant supplement at all, let alone every day.
That being said, if you are deficient in an antioxidant like vitamin C or E, daily supplementation is usually recommended to replenish your levels of the nutrient and reverse or prevent side effects from a deficiency. The most powerful antioxidant supplement is the one you are deficient in.
If you don't have a deficiency in a specific antioxidant nutrient, then you probably won't benefit from taking a supplement.
And you'd be better off focusing on incorporating more antioxidant-rich foods in your diet. Antioxidant-rich foods, like fruits and veggies, are associated with loads of health benefits and no safety concerns, whereas supplements may lead to harm when overdone or taken with certain medications.
Antioxidant supplements are linked with health issues in certain populations. Since they contain highly concentrated doses of nutrients, they may increase the risk of toxicity. They can also interact with medications, potentially decreasing the medication's effectiveness or exacerbating its effects.
Antioxidant supplements are also expensive, so they can put an unnecessary dent in your wallet. Despite how alluring antioxidant supplements may be, research shows that they don't really benefit health unless you're deficient in the given nutrient. That being said, adding more antioxidant-rich foods to your diet can benefit your health in numerous ways since antioxidant-rich foods are also rich in nutrients like fiber, which have a plethora of health benefits.
