Antioxidants and heart health -

Good sources of lycopene include:. Research also shows that lycopene is better absorbed by our bodies when heated and combined with healthy fats such as olive and coconut oil. Some great ways to get the best absorption of these lycopene-rich foods are through recipes like:.

Resveratrol, which is found in red wine, is an antioxidant that may help prevent CHD. The potential heart-healthy benefits of red wine and other alcoholic drinks look promising.

Those who drink moderate amounts of alcohol, including red wine, seem to have a lower risk of heart disease. Alcohol can be addictive and cause other health problems.

Astaxanthin antioxidant properties include being linked to improved blood flow and lowering oxidative stress in smokers and overweight people. A comparison study of astaxanthin and other carotenoids showed that it displayed the highest antioxidant activity against free radicals. Astaxanthin is most commonly found in:.

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 AREDS , found 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.

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.

Research shows that some vitamin supplements can increase our cancer risk. For example, vitamin A beta-carotene has been associated with a reduced risk of certain cancers, but an increase in others — such as lung cancer in smokers if vitamin A is purified from foodstuffs.

A study examining the effects of vitamin E found that it did not offer the same benefits when taken as a supplement. A well-balanced diet, which includes consuming antioxidants from whole foods, is best.

If you need to take a supplement, seek advice from your doctor or dietitian and choose supplements that contain all nutrients at the recommended levels. 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:. To meet your nutritional needs, as a minimum try to consume a serve of fruit and vegetables daily. Although serving sizes vary depending on gender, age and stage of life, this is roughly a medium-sized piece of fruit or a half-cup of cooked vegetables.

The Australian Dietary Guidelines External Link has more information on recommended servings and portions for specific ages, life stage and gender. It is also thought antioxidants and other protective constituents from vegetables, legumes and fruit need to be consumed regularly from early life to be effective.

Cardiovascular disease CVDas the leading cause of death worldwide, is the collective term named for disorders afflicting the blood vessels and heart. Inflammation and enhanced oxidative stress have been shown as fundamental risk factors in the onset and progression of CVD. Chronic inflammatory conditions attenuate blood levels of antioxidants because of the continuous generation of elevated levels of reactive oxygen species ROS.
