The Victorian government backs antioxidant properties, but says whole foods are best
The Victorian Department of Health has posted information on its website backing the ability of antioxidants to battle free radicals.

The government agency said antioxidants such as “vitamins A, C and E, and the minerals copper, zinc and selenium”​ could deliver free radical-fighting benefits, but: “Other dietary food compounds, such as the phytochemicals in plants and zoochemicals from animal products, are believed to have greater antioxidant effects than either vitamins or minerals.”

“These are called the non-nutrient antioxidants and include phytochemicals, such as lycopenes in tomatoes, and anthocyanins found in cranberries.”

Foods versus supplements

The information sheet approved by Deakin University referenced differing opinions that exist about the bioavailability of antioxidants in differing forms, suggesting whole foods were better mediums than food supplements.

“Some studies suggest that antioxidants are less effective when isolated from food and presented in tablet form,”​ it stated.

“For instance, 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 didn’t offer the same benefits when taken as a supplement. Also, antioxidant minerals or vitamins can act as pro-oxidants or damaging ‘oxidants’ if they are consumed at levels significantly above the recommended amounts for dietary intake.

“A well-balanced diet, which includes consuming antioxidants from whole foods, is best. If you insist on taking a supplement, seek supplements that contain all nutrients at the recommended levels.”

It concluded by noting antioxidant research is “divided” ​a reality represented liberally on NutraIngredients, and which Stephen Daniells commented on here​.

Antioxidants inside

Antioxidants have not impressed the European Food Safety Authority (EFSA)’s health claims panel and the term itself is likely to soon become an unauthorised health claim in the EU.

EFSA’s health claims panel has stated: “…no evidence has been provided to establish that having antioxidant activity/content and/or antioxidant properties is a beneficial physiological effect.”

But the panel has concluded of vitamin E, “that a cause and effect relationship has been established between the dietary intake of vitamin E and protection of DNA, protein and lipids from oxidative damage.”

Vitamin C has won a similar health claim.

It is now down to the European Commission and member states to interpret these opinions before adoption, rejection or amendment, and the use of terms like ‘polyphenol’ or ‘flavonol’ that are relevant to them.

In the most recent batch of article 13 general health claim opinions EFSA found polyphenols extracted from olives could reduce LDL cholesterol levels, but no antioxidant link was demonstrated.

What about vitamin D - more important to Victorians than antioxidants!

Posted by Annie Claire,

Would like to see the Victorian Government taking a leaf out of Denmark's book on vitamin D supplementation instead of fiddling about with antioxidant supplementation of foods. There is quite a bit of dissention about which antioxidants are effective, how much etc, but there is very little dissention regarding the low vitamin D levels epidemic in Victoria and the World! With most of Victoria being too far south for residents to obtain any useful sun exposure in Autumn, Winter and Spring and all advice being to avoid sun during the only part of the day when UVB rays are adequate to make vitamin D in the skin, the epidemic is out of control. We are constantly exposed to a ridiculous and malicious anti sun campaign that frightens children and adults alike and keeps people from any sun exposure at all which in turn exaccerbates the epidemic of people with low and very low vitamin D levels. You could say I have "seen the light" and can't believe how much better I am since supplementing with vitamin D and getting sensible sun exposure. Forget antioxidants and get with the program - vitamin D rocks!!!!!
