Food additives you should avoid


What are food additives?

Food additives are chemicals that are added to food and beverages to keep them fresh or enhance their colour, flavour and texture. They can be made from natural or artificial sources.

Who approves food additives?

Food Standards Australia New Zealand regulates food additives. The use of food additives are governed by the Food Standards Code. If a food company wants to start using a new additive, they need to provide evidence of its safety to FSANZ. FSANZ will then review the evidence before it approves it for use in Australia.

Where are food additives listed?

The ingredients list on the food label of the product will list food additives, however if a food additive takes up less than 5% of the complete food product, it doesn’t need to be listed. So, it’s possible there are small amounts of food additives in a product that aren’t on the food label or listed on the packaging.

According to the Food Standards Australia New Zealand, most food additives are listed by their class name and then the name of the food additive or the food additive number. For example, Colour (Caramel I) or Colour (150a). You can identify flavouring additives by the words “flavouring” or “flavour” or by a more specific name or description. As the Australian Dietitians Association states, ingredients in manufactured foods are listed in descending order of quantity. This means the first ingredient is the main ingredient, and the last ingredient listed is the smallest by weight.

You can get a list of food additives by name or number at Food Standards Australia and New Zealand.

Which food additives should you avoid?


As Choice Australia highlights, in 2010, a UK Government-funded study found that there was a link between a mixture of some colourings and hyperactivity in children. The British Food Standards Agency has since encouraged food manufacturers to find alternatives to these colours and some have stopped using them completely. Within the EU,  products containing these colours are now labelled “May have an adverse effect on activity and attention in children”.

The colours were tartrazine (102), quinoline yellow (104), sunset yellow FCF (110), carmoisine (122), ponceau 4R (124) and allura red AC (129).

Yet, the Food Standards Australia and New Zealand states that these food additives don’t pose any risk to public health and safety for children in Australia.


Flavoured drinks such as soft drinks, flavoured mineral waters, cordials and fruit drinks may contain benzene (a known carcinogen). While not added to the products, the combination of sodium benzoate (211) and potassium benzoate (212) and ascorbic acid (vitamin C) can form benzene which is a known carcinogen. Choice Australia recommends steering clear of products that contain benzoates and ascorbic acid when found  in combination.

Processed meats

The World Health Organisation International Agency for Research has classified both potassium and sodium nitrate (249, 250) as probably carcinogenic to humans. WHO recommend limiting or avoiding processed meats like sausages, frankfurts, salami, bacon and ham.

Wine and dried fruit

Preservatives that Sulphur (220 – 228) can trigger asthma attacks. These are often used in wine, beer, fruit juices, processed foods, and dried fruits.

Artificial sweeteners

Artificial sweeteners are often used as a weight-loss aid but there’s conflicting research about how healthy they are for you. As Choice Australia state, overall being overweight poses a bigger risk to your health than artificial sweeteners.
