Antioxidant fruit supplements -
However, studies have shown that cauliflower, peas, and zucchini lose much of their antioxidant activity in the cooking process.
Keep in mind that the important thing is eating a variety of antioxidant-rich foods, cooked and raw. There is no set recommended daily allowance RDA for antioxidants, but a high intake of fresh plant-based produce is considered healthful.
It is worth remembering that, while studies link the consumption of fruits and vegetables with better overall health, it is not clear whether how far this is due to the activity of antioxidants. In addition, caution is needed regarding supplements. The National Institutes of Health NIH warn that high doses of antioxidant supplements can be harmful.
A high intake of beta-carotene, for example, has been linked to an increased risk of lung cancer in smokers. A high dose of vitamin E has been found to increase the risk of prostate cancer , and the use of some antioxidant supplements has been linked to a greater risk of tumor growth.
Antioxidant supplements may also interact with some medications. It is important to speak with a health provider before using any of these products. Overall, research has not proven that taking any particular antioxidant as a supplement or through a food can protect against a disease.
There may be some benefit for people at risk of age-related macular degeneration, but it is essential to seek advice from a doctor about whether to use supplements, and which ones to use. Free radicals have been linked to a range of diseases, including heart disease, cancer, and vision loss, but this does not mean that an increased intake of antioxidants will prevent these diseases.
Antioxidants from artificial sources may increase the risk of some health problems. As a result, it is important to seek out natural sources of antioxidants, in the form of a healthful diet. Consuming fruits and vegetables has been linked to a lower rate of chronic diseases, and antioxidants may play a role.
However, it is unlikely that consuming added antioxidants, especially in processed foods, will provide significant benefits.
In addition, anyone considering taking antioxidant supplements should speak to a health provider first. Read the article in Spanish. Free radicals are unstable atoms that can cause damage to cells and lead to illnesses and the aging process.

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.

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.

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.

| Actions for this page | 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.

Free radicals in the body cause inflammation and can contribute to diseases like cancers, diabetes, and heart disease to name a few. So, the antidote to oxidation is the antioxidant. Vitamins like vitamins A, C, and E are examples of antioxidants. So are other compounds in foods like carotenoids and phenols. These compounds sacrifice their electrons to stop the oxidation process; this why squirting some lemon juice on your sliced apples, bananas and avocados slows down the browning process. As with many things in life and health, the key is maintaining a good balance. In this case, as the balance between oxidation and antioxidation. We can throw off that balance with exposure to too much alcohol, smoking, or environmental pollutants. Even over-exercising or too much sun exposure can create too much oxidation. The best sources of antioxidants to combat this effect are nutritious whole foods, like colourful fresh produce, e. In fact, the more colourful and darker the plant is, the higher levels of antioxidants it usually has. Chemicals that give the plants their deep colours are often the antioxidants themselves. Blueberries are probably one of the most studied antioxidant foods. They contain a range of phytochemical i. Can you imagine how much healthier people can be if they added a few more servings of antioxidant-rich fruits and vegetables to their days? Compared with eating a nutrient-dense antioxidant-rich colourful array of plants, antioxidants supplements have fallen short. And these are diseases that are known to be reduced in people who eat a lot of foods that are naturally full of antioxidants. In fact, too much of any individual antioxidant, like when overdoing supplements, can be harmful. Too much vitamin A is linked to increased risk of hip fractures and prostate cancer. Too much beta-carotene increases the risk of lung cancer in smokers. Too much vitamin E increases the risk of prostate cancer, lung infections, heart failure, and even death. One of the reasons why we think that antioxidant foods work oh-so-much better than antioxidant supplements is because of synergy. The concept of synergy means that by taking one component out of healthful food i. This is the difference between eating a whole orange and taking a vitamin C supplement. The orange is going to have more than just vitamin C, and many of those compounds will work together for overall health better than just isolating one and having higher-than-normal doses of it.

Catechins are types of flavanols that have strong antioxidant properties. One of the best-studied catechins is EGCG epigallocatechin gallate , which is found naturally in teas, such as green, black, and white. Both Smith and Moskowitz say that EGCG has a profound impact on inflammation and oxidative stress. As members of the flavonoid group, anthocyanins are what give certain foods their natural blue, red, or purple color. For that reason, Moskowitz says that the best sources of anthocyanins include blackberries, blueberries, cranberries, cherries, red cabbage, and blackcurrants. Pritchard also recommends acai as another source of anthocyanins. Not only do they have antioxidant properties that can improve vascular health and lower blood pressure, but they are also anti-inflammatory and anti-bacterial.
