Does Milk Block Antioxidants in Foods and Beverages? Synthetic vs Natural Nutrients: Does It Matter? Have studies been done on the health effects of antioxidants? For example: A review of 95 observational studies, with more than 2 million total participants, showed that people who had higher intakes of fruits and vegetables had lower risks of cardiovascular disease and cancer.

A study from the United Kingdom in which 72, people were followed for an average of 9 years showed that higher intakes of fruits and vegetables were associated with a lower risk of cataracts.

For example, in a study of adults living in rural areas in the United States, eating at least five servings of fruits and vegetables daily was associated with several other factors that might affect health, such as getting at least moderate physical activity and having had a routine medical exam in the past year.

Antioxidants consumed as purified chemicals might act differently than those consumed in foods, which contain complex mixtures of substances.

The high doses of antioxidants in dietary supplements may have different effects than the smaller amounts in foods. Can antioxidant supplements help to prevent cancer? In , the U. Preventive Services Task Force, an independent panel of experts that makes evidence-based recommendations about disease prevention, recommended against the use of beta-carotene or vitamin E supplements for cancer prevention.

They also concluded that the evidence is insufficient to make recommendations about supplements of other single nutrients or pairs of nutrients. Beta-carotene supplementation led to an increase in risk of lung cancer, with the strongest evidence of an increase in risk in people at high risk of this type of cancer smokers and people with occupational exposure to asbestos , as well as an increased risk of death from cardiovascular disease.

Can antioxidant supplements help to prevent cardiovascular disease? Preventive Services Task Force recommended against the use of beta-carotene or vitamin E supplements for prevention of cardiovascular disease.

Beta-carotene supplementation led to an increase in risk of lung cancer, with the strongest evidence of an increase in risk in people at high risk of this type of cancer smokers and people with occupational exposure to asbestos , and an increase in deaths from cardiovascular disease.

Can antioxidant supplements help to prevent cataracts? Are antioxidant supplements helpful for age-related macular degeneration AMD? A review that examined the results of 5 studies 76, participants did not find any significant benefit of vitamin E, vitamin C, or beta-carotene supplementation in preventing or delaying the onset of AMD.

For people who already have AMD, supplements containing a combination of antioxidants and zinc may slow the progression of the disease. The evidence for this comes from two large studies sponsored by the National Institutes of Health—the Age-Related Eye Disease Study AREDS and Age-Related Eye Disease Study 2 AREDS2.

AREDS evaluated the effects of a dietary supplement containing high doses of vitamins C and E, beta-carotene, zinc, and copper on the progression of AMD.

Almost 4, people participated in this study, including 3, who had AMD. Among people with intermediate AMD, the supplement reduced the risk of developing advanced AMD by about 25 percent. AREDS2 tested modifications to the original AREDS formula in about 4, people who were at high risk of progressing to advanced AMD.

Participants were randomly assigned to groups that received the original formula or various modified versions. The modifications included removing beta-carotene and adding lutein and zeaxanthin two carotenoids that are found in the eye.

Because the link between beta-carotene and an increased risk of lung cancer in smokers was known before this study started, current smokers were not assigned to groups that received beta-carotene; only nonsmokers and former smokers were included in those groups.

After 10 years of follow-up, lutein and zeaxanthin proved to be more effective than beta-carotene in reducing the risk of progression to advanced AMD.

Beta-carotene increased lung cancer risk among former smokers, but lutein and zeaxanthin did not. Are antioxidants helpful for preserving cognitive function? Two recent reviews looked at evidence related to this topic and found mixed results.

There was low-certainty evidence of better overall cognitive function after taking beta-carotene for 18 years and after taking vitamin C for 5 to 10 years, but no effects were seen after shorter periods of supplementation or after taking vitamin E.

The effects seen in the studies were small. Another review looked at studies of vitamin and mineral supplementation in people who already have mild cognitive impairment.

Two of the studies involved antioxidants. In one study participants , high-dose supplementation with vitamin E for 3 years did not have a significant effect on progression of mild cognitive impairment to dementia.

In the other study, which involved combined vitamin E and C supplementation participants , the evidence was too low in quality for any conclusions to be reached about cognitive effects.

Are antioxidant supplements safe? Not necessarily. Antioxidants can have harmful effects when taken at high doses. These effects have been seen primarily in people at high risk, such as smokers.

Vitamin E supplements may also interact with certain medicines, including anticoagulant or antiplatelet medicines. High doses of vitamin C can cause diarrhea, nausea, and stomach cramps. Vitamin C supplements may also interact with cancer treatments, such as chemotherapy and radiation therapy, and they can worsen iron overload in people with hemochromatosis, a condition that causes the body to store too much iron.

Combinations of antioxidants may have undesirable effects. For example, in one study, a combination of vitamin E, vitamin C, selenium, and beta-carotene reduced the cholesterol-lowering effects of two drugs taken together for this purpose. Tips To Consider. If you have age-related macular degeneration, consult your health care providers to determine whether supplements of the types used in the AREDS or AREDS2 trials are appropriate for you.

Recently completed large randomized clinical trials with low risks of bias and systematic reviews of randomized clinical trials taking systematic errors 'bias' and risks of random errors 'play of chance' into account have shown that antioxidant supplements do not seem to prevent cancer, cardiovascular diseases, or death.
