Navigating UK Food Regulations: An Overview of Prohibited and Restricted Dyes
Navigating the world of food additives and understanding regulatory nuances is crucial for a health-conscious diet. While the UK's approach to food dyes is largely aligned with EU regulations—particularly concerning labelling requirements—some significant differences and outright bans exist. Since Brexit, the UK maintains its own list of authorised additives, managed by the Food Standards Agency (FSA), based on scientific assessments. This framework ensures that any food additive used must be safe for consumption within specified limits.
The 'Southampton Six' and the Shift to Voluntary Action
A pivotal moment in UK food additive regulation came with the 2007 Southampton study, which linked certain artificial colours to increased hyperactivity in children. While this did not lead to a legislative ban at the time, it triggered a significant shift in the food industry. The FSA issued guidance that encouraged the voluntary removal of six specific azo dyes, often referred to as the 'Southampton Six'. As a result, many UK manufacturers voluntarily removed these colours from their products. However, the dyes were not outright banned but require a warning label: "[name or E number of the colour(s)]: may have an adverse effect on activity and attention in children".
The 'Southampton Six' includes:
- E102 (Tartrazine): A yellow dye found in items like sweets and fizzy drinks.
- E104 (Quinoline Yellow): A greenish-yellow dye.
- E110 (Sunset Yellow FCF): A yellow-orange dye.
- E122 (Carmoisine): A red-maroon dye.
- E124 (Ponceau 4R): A red dye.
- E129 (Allura Red AC): An orange-red dye.
Fully Prohibited and Unauthorised Food Dyes in the UK
Beyond the voluntarily phased-out colours, certain dyes and additives are completely banned or not authorised for use in the UK. This often depends on specific product types or is a result of updated scientific evidence. The following are some key examples:
- E128 (Red 2G): This red azo dye was banned in 2007 across the EU, including the UK, following safety concerns about its conversion into a suspected carcinogen in the body.
- E171 (Titanium Dioxide): As of June 2022, this additive, used to whiten foods like chewing gum and sauces, is no longer approved in the EU due to its potential genotoxic effects. The UK has also adopted this measure, and its use is prohibited.
- E127 (Erythrosine/Red 3): This additive is permitted in the UK only for specific uses, primarily for cocktail and candied cherries. Its use in most other products, such as sweets and cereals, is not permitted.
- Brominated Vegetable Oil (BVO): This is not a permitted food additive in the UK, especially not in flavoured drinks, though it is sometimes found in US imported products.
- Mineral Oil (E905a): Used as a glazing agent in some countries, this is not a permitted additive under the confectionery food category in the UK and has been a source of trading standards alerts.
The Challenge with Imported Goods
One of the most significant challenges for UK consumers comes from imported products, particularly from the US, where a different set of regulations applies. Trading Standards have issued alerts about popular American candies and drinks containing unauthorised dyes. For example, some products might contain Tartrazine (E102), listed as 'Yellow 5', despite its restricted use in certain UK goods. Consumers should be vigilant about checking ingredient labels, as non-compliant products must be removed from sale by businesses.
Making Healthier Choices: Spotting the Additives
Choosing a diet with fewer artificial colours requires a simple but diligent approach to label reading. The FSA encourages manufacturers to use clearer labelling, and consumer demand has driven many to switch to natural alternatives. These can include pigments from beetroot (E162), annatto (E160b), and paprika (E160c).
Banned and Voluntarily Phased-out Dyes vs. Natural Alternatives
| Category | Banned/Voluntarily Removed UK Dye | Typical Use | Health Concern | Natural Colour Alternative | Source of Alternative |
|---|---|---|---|---|---|
| Red | E128 (Red 2G) - Banned | Meat products | Suspected carcinogen | Beetroot Red (E162) | Beetroot |
| Red | E122 (Carmoisine) - Voluntary Phase-out | Jellies, sweets | Hyperactivity in children | Carmine (E120) | Cochineal insects |
| Red | E129 (Allura Red AC) - Voluntary Phase-out | Confectionery, drinks | Hyperactivity in children | Lycopene (E160d) | Tomatoes |
| Yellow | E102 (Tartrazine) - Voluntary Phase-out | Fizzy drinks, lollies | Hyperactivity in children | Curcumin (E100) | Turmeric |
| Yellow | E110 (Sunset Yellow FCF) - Voluntary Phase-out | Snacks, squashes | Hyperactivity in children | Annatto (E160b) | Annatto seeds |
| White | E171 (Titanium Dioxide) - Banned | Coatings for sweets, sauces | Potential genotoxicity | Calcium Carbonate (E170) | Chalk |
How to Read UK Labels for Food Dyes
In the UK, food additives are identified by their 'E-number' or their common name. A list of ingredients is provided in descending order of weight. To avoid restricted or phased-out colours, look for the 'E' number or chemical name. The labels for the 'Southampton Six' colours must carry the hyperactivity warning, making them easier to identify. However, this warning is not required for all products or all countries, so vigilance is key, especially with imported items.
Conclusion
Understanding which food dyes are banned in the UK, which are restricted, and which require specific warning labels is crucial for anyone looking to make informed nutrition choices. The UK's food safety landscape, though evolving post-Brexit, maintains stringent standards, particularly for additives linked to health issues like hyperactivity. While outright bans exist for certain substances like Titanium Dioxide and Red 2G, many others are voluntarily phased out or require prominent labelling. By scrutinising ingredient lists, especially on imported products, consumers can effectively manage their intake of artificial colours. Ultimately, a balanced and healthy diet benefits from a deeper awareness of the ingredients and a preference for naturally coloured foods whenever possible.

| Brominated Vegetable Oil (BVO) | Banned | Permitted in specific quantities for some citrus-flavoured drinks |
| Approach to Regulation | Precautionary Principle; more restrictive on certain additives | Additive-specific Approval; wider list of permitted dyes compared to the UK/EU |
How to Choose a Nutrition Diet with Fewer Artificial Dyes
For those seeking to minimise or eliminate artificial dyes from their diet, the approach should be multi-pronged. Firstly, prioritise whole, unprocessed foods like fresh fruits, vegetables, and lean proteins, which are naturally free of synthetic colours. When purchasing packaged goods, make it a habit to check the ingredients list for E-numbers, especially the ones associated with the 'Southampton Six' or other restricted dyes. Be particularly wary of imported snacks or sweets, which may not comply with UK standards. Choosing products explicitly marketed with 'natural colours' or 'no artificial colours' is another effective strategy. Learning to use natural colouring agents, such as turmeric for yellow, paprika for red, and spinach for green, in your own cooking allows for creative and safe flavouring and colouring at home.
This holistic approach ensures that you have control over the additives you consume, providing a healthier and more transparent nutrition diet for you and your family. For further guidance on food safety standards, the official FSA website is an indispensable resource.
