Antioxidant vitamins -
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.

Scientists discover biological mechanism of hearing loss caused by loud noise — and find a way to prevent it. Very few cases in the SELECT trial were of advanced prostate cancer, further limiting the interpretation of the findings.
A six-year trial found that vitamin E, in combination with vitamin C, beta carotene, and zinc, offered some protection against the development of advanced age-related macular degeneration AMD , but not cataracts, in people who were at high risk of the disease.
Vitamin E is found in plant-based oils, nuts , seeds, fruits , and vegetables. Because vitamin E is found in a variety of foods and supplements, a deficiency in the U.
is rare. People who have digestive disorders or do not absorb fat properly e. The following are common signs of a deficiency:. There is no evidence of toxic effects from vitamin E found naturally in foods. Most adults who obtain more than the RDA of 22 IU daily are using multivitamins or separate vitamin E supplements that contain anywhere from IU daily.
There have not been reports of harmful side effects of supplement use in healthy people. However, there is a risk of excess bleeding, particularly with doses greater than mg daily or if an individual is also using a blood thinning medication such as warfarin.
For this reason, an upper limit for vitamin E has been set for adults 19 years and older of mg daily IU of any form of tocopherol supplement. Due to occasional reports of negative health effects of vitamin E supplements, scientists have debated whether these supplements could be harmful and even increase the risk of death.
Researchers have tried to answer this question by combining the results of multiple studies. In one such analysis, the authors gathered and re-analyzed data from 19 clinical trials of vitamin E, including the GISSI and HOPE studies [50]; they found a higher rate of death in trials where patients took more than IU of supplements a day.
While this meta-analysis drew headlines when it was released, there are limitations to the conclusions that can be drawn from it. Some of the findings were based on very small studies.
In some of these trials, vitamin E was combined with high doses of beta-carotene, which itself has been related to excess mortality. Other meta-analyses have come to different conclusions. So it is not clear that these findings would apply to healthy people.

Vitamin E and Health Heart disease For a time, vitamin E supplements looked like an easy way to prevent cardiovascular disease. A later analysis found that women who took the vitamin E supplements also had a lower risk of developing serious blood clots in the legs and lungs, with women at the highest risk of such blood clots receiving the greatest benefit.
In the GISSI Prevention Trial, the results were mixed but mostly showed no preventive effects after more than three years of treatment with vitamin E among 11, heart attack survivors.
Randomized controlled trials in people without heart disease at baseline. The SU. MAX randomized controlled trial found that seven years of low-dose vitamin E supplementation as part of a daily antioxidant pill reduced the risk of cancer and the risk of dying from any cause in men, but did not show these beneficial effects in women; the supplements did not offer any protection against heart disease in men or women.
Researchers found that taking vitamin E supplements of IU every other day, alone or with vitamin C, failed to offer any protection against heart attacks, strokes, or cardiovascular deaths.
Cancer Taken as a whole, observational studies have not found that vitamin E in food or supplements offers much protection against cancer in general, or against specific cancers. Age-related vision diseases A six-year trial found that vitamin E, in combination with vitamin C, beta carotene, and zinc, offered some protection against the development of advanced age-related macular degeneration AMD , but not cataracts, in people who were at high risk of the disease.
More research is needed. Amyotrophic Lateral Sclerosis ALS : One large prospective study that followed nearly 1 million people for up to 16 years found that people who regularly took vitamin E supplements had a lower risk of dying from ALS than people who never took vitamin E supplements.

Vitamin E has the ability to protect cells from free radical damage as well as reduce the production of free radicals in certain situations. However, conflicting study results have dimmed some of the promise of using high dose vitamin E to prevent chronic diseases. The Recommended Dietary Allowance RDA for vitamin E for males and females ages 14 years and older is 15 mg daily or 22 international units, IUincluding women who are pregnant. Lactating women need slightly more at 19 mg 28 IU daily. For a time, vitamin E supplements looked like an easy way to prevent cardiovascular disease.

An atom or group of atoms with an unpaired electron is called a free radical. Free radicals are inherently unstable and highly reactive. They steal electrons from other molecules in order to stabilize themselves, but in doing so, they create additional free radicals. This electron-grabbing is called oxidation and can set up a chain reaction, creating new free radicals and damaging important molecules along the way, similar to how one falling domino can bring down countless more.

Another big misconception is that Antioxidant vitamins are interchangeable. Each one has Antixoidant chemical behaviors and biological properties.

This means that no single substance can do the work of the whole vigamins. Antioxidants came to Antioxiddant Antioxidant vitamins in the s, when Antioxidqnt began to understand that free radical damage was involved in the early stages of artery-clogging atherosclerosis.

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 diseasescancer, 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 fruitsvegetablesand whole grains —all rich in networks of naturally occurring antioxidants and their helper molecules—provides protection against many scourges of aging.

Home Nutrition News What Should I Eat? Ina 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.
The vitamins had no effect on overall rates of cardiovascular disease. Lung disease A study from the Journal of Respiratory Research found that different isoforms of vitamin E called tocopherols had opposing effects on lung function.
Cancer When it comes to cancer prevention, the picture remains inconclusive for antioxidant supplements.
MAX randomized placebo-controlled trial showed a reduction in cancer risk and all-cause mortality among men taking an antioxidant cocktail low doses of vitamins C and E, beta-carotene, selenium, and zinc but no apparent effect in women, possibly because men tended to have low blood levels of beta-carotene and other vitamins at the beginning of the study.
Age-related eye disease A six-year trial, the Age-Related Eye Disease Study AREDSfound that a combination of vitamin C, vitamin E, beta-carotene, and zinc offered some protection against the development of advanced age-related macular degeneration, but not cataracts, in people who were at high risk of the disease.
However, relatively short trials of lutein supplementation for age-related macular degeneration have yielded conflicting findings. The study found that people taking the vitamins were less likely to progress to late-stage AMD and vision loss. However, the study authors noted that taking lutein and zeaxanthin alone or vitamin E alone did not have a beneficial effect on these eye conditions.
The Selenium and Vitamin E Cancer Prevention Trial SELECT Eye Endpoints Study, which followed 11, men for a mean of five years, did not find that vitamin E and selenium supplements, in combination or alone, protected from age-related cataracts.
It did not find that antioxidant supplements of vitamin E or selenium, alone or in combination, protected against dementia compared with a placebo. Early death A meta-analysis of 68 antioxidant supplement trials found that taking beta-carotene and vitamin A and E supplements increased the risk of dying.
It was also difficult to compare interventions because the types of supplements, the dosages taken, and the length of time they were taken varied widely. The same authors conducted another systematic review of 78 randomized clinical trials on antioxidant supplements including beta-carotene, vitamin A, vitamin C, vitamin E, and selenium alone or in combination.
The study found that both people who were healthy and those with diseases taking beta-carotene and vitamin E supplements had a higher rate of death. The duration of the studies varied widely from one month to 12 years, with varying dosages.
The first inkling came in a large trial of beta-carotene conducted among men in Finland who were heavy smokers, and therefore at high risk for developing lung cancer. The trial was stopped early when researchers saw a significant increase in lung cancer among those taking the supplement compared to those taking the placebo.
Again, an increase in lung cancer was seen in the supplement group. MAX trial, rates of skin cancer were higher in women who were assigned to take vitamin C, vitamin E, beta-carotene, selenium, and zinc.
These results came from the Selenium and Vitamin E Cancer Prevention Trial SELECT that followed 35, men for up to 12 years. References National Center for Complementary and Integrative Health NCCIH.

Vitamin C has not been shown to prevent the common cold , but it may reduce its severity and duration. In addition, higher doses may cause stomach upset Similarly, exposure to secondhand smoke also increases vitamin C needs Yet, this additional need for vitamin C can be easily met through diet and without taking antioxidant supplements. For the most part, the use of antioxidant supplements is discouraged, though the antioxidant vitamin C can benefit people with the common cold or those who smoke. Still, needs can often be met through diet instead of supplements. Getting antioxidants from food rather than supplements is much safer and healthier.
