Food Additives Banned by One or More Countries
Due to requests I have produced a list of additives which have been banned by various countries. I’ve gone through the book ‘E for Additives’ by Maurice Hanssen (1987) noting which ones have been singled out by governments for exclusion from diet.
I have done this so that it makes clear that large bodies of educated people in the employment of governments around the world have surveyed the available evidence on the properties of these chemicals and have for one reason or another decided that these should not be allowed in the food chain. In short, there is compelling evidence as to these being poisonous to our health.
First a short introduction to food additives…
Food additives are used for various purposes; there are thousands now available for industrial food manufacturers to draw on to make a ‘shelf stable’ product. The more industrialised your food sources the more you are exposed to food additives. Some food additives are good for you (i.e. vitamin C is used as a preservative) and some food additives are not good for you (i.e. sulfites cause allergic reactions in asthmatics). How do we inform ourselves to make decisions on what is found in the food we buy ?
There is a lot of media around and videos like these, whilst informative, leave us with no information sources to refer to. Information sources which offer no accountability for their authorship but which are nevertheless interesting, edifying and entertaining.
In this age of information overload the skills of being able to get reliable information on which to make decisions about what we take in through our diet and its effects on health are vital. This article is about showing people how to access the toxicological information from the health and safety legislated Material Safety Data Sheet (MSDS) system as a chief free and reliable information resource.
I have been contacted by someone who has brought critical reflections to this article and suggested that the legislative information which I have quoted needs updated. I am very appreciative of this and have worked to incorporate the suggested points into this article. Incorporated in this article is work done many years ago for ‘hyperactive’ children’s support groups where parents were concerned and confused by clashing opinions and seeming constant pantomime of journalism surrounding health matters.
To assist parents I showed them how to use a particularly useful book ‘E for Additives’ by Maurice Hanssen which was published in 1987 but is still useful today. Despite time passing, Hanssen did a service to the information seeing community to distill into a single book a well categorised list of all the additives used at the time along with well written, simple overviews and the research associated with each additive.
The additive system came out of the pragmatism of food manufacturers as western worlds started transforming their food chain. Foods started to be designed from chemical matrices and the food chain was transformed into giant factories which change the nature of the stuff itself.
Key here is being able to reference reliable information resources so that informed decisions on what to exclude in the diet can be made. Wherever a large amount of a chemical is produced there is legislation in place to say that when this is stored in a warehouse, and should there be an accident, certain health and safety information has to be understood by the people who work in the warehouse, firefighters, doctors and emergency workers.
This is stored on a document called the Material Safety Data Sheet (MSDS) which is freely available to download on the internet. This offers an encyclopedic information resource over a ‘Globally Harmonized System’ which contains the following details in each report:
- SECTION 1: Identification of the substance/mixture and of the company/undertaking
- SECTION 2: Hazards identification
- SECTION 3: Composition/information on ingredients
- SECTION 4: First aid measures
- SECTION 5: Firefighting measures
- SECTION 6: Accidental release measure
- SECTION 7: Handling and storage
- SECTION 8: Exposure controls/personal protection
- SECTION 9: Physical and chemical properties
- SECTION 10: Stability and reactivity
- SECTION 11: Toxicological information
- SECTION 12: Ecological information
- SECTION 13: Disposal considerations
- SECTION 14: Transport information
- SECTION 15: Regulatory information
- SECTION 16: Other information
Should you want to find other solid and dependable (legislation linked) information on the toxicity of a substance (which is a good habit) I would recommend looking up the Material Safety Data Sheet on the chemical you are checking. All you have to do is type into Google “ascorbic acid material data safety sheet” and you will be able to access full reports on this given chemical.
Ascorbic acid which is vitamin C is created in vast quantities and stored in its pure chemical form until manufacturers call upon warehouses to deliver so many kilos or tonnes of E300 to a given place. You can easily then look up the toxicological information with relative confidence in what information you can find. This information supplemented with reading from peer reviewed journals and textbooks as needed provides the basis from which you can make informed decisions.
Peer reviewed journals and textbooks come from a system of mutual critical assessment of individual findings. I argue that what are considered professional and academic texts are better information sources because they follow the convention of containing inside them the information sources which led their authors to understand some piece of knowledge. A piece of writing or media which does not tell me who did the piece of science and where I can find that information and interpret it for myself is not something which I can base my decisions on with regards to my health.
Taking time to investigate what is listed on the sides of bottles and products gives you the chance to make decisions that affect your health. It allows you to have conversations with professionals which need to be had. For example you can use Material Safety Data Sheets to look up what is known about the toxicity of a drug as long as you search for the generic name. This means that rather than a brand name like Paracetamol you would look up Acetaminophen Material Safety Data Sheet.
These provide you with concise toxicological data. A short summary that can give you a clear indicator of how toxic something has been discovered to be.
Here is an example of one on Benzene:
Note that in ‘Section 3: Hazards Identification’ of the above Data Safety Hazard Sheet, anyone will be able to find clear information about what is known about the toxic nature of the substance. Material Data Safety Sheets are reliable sources of information on toxicology. So, in the above Material Data Safety Sheet we can read about the following:
- Potential Acute Health Effects: Very hazardous in case of eye contact (irritant), of inhalation. Hazardous in case of skin contact (irritant, permeator), of ingestion. Inflammation of the eye is characterized by redness, watering, and itching. Potential Chronic Health Effects:
- CARCINOGENIC EFFECTS: Classified A1 (Confirmed for human.) by ACGIH, 1 (Proven for human.) by IARC.
- MUTAGENIC EFFECTS: Classified POSSIBLE for human. Mutagenic for mammalian somatic cells. Mutagenic for bacteria and/or yeast.
- TERATOGENIC EFFECTS: Not available.
- DEVELOPMENTAL TOXICITY: Classified Reproductive system/toxin/female [POSSIBLE]. The substance is toxic to blood, bone marrow, central nervous system (CNS). The substance may be toxic to liver, Urinary System. Repeated or prolonged exposure to the substance can produce target organs damage.
It is short and tells you the points which you really want to know. Is this carcinogenic ? Is this toxic to any part of my body (or the environment) ? This information can help me make decisions about whether I want this in my food
An approach like this can help inform you about issues such as sources of benzene in soft drinks, for example. Sodium Benzoate is an additive which you can find in some soft drinks. Knowing what you know now (ibid that benzene is confirmed carcinogenic for humans) would you want to drink a soft drink which used benzene based preservatives ?
There is a wikipedia article illustrating some of the controversies about benzene in our food chain: https://en.wikipedia.org/wiki/Benzene_in_soft_drinks
It has been suggested by William Leyland that “The idea that a benzoate compound is toxic because benzene is toxic is exactly as scientifically illiterate as saying that common salt (sodium chloride) is toxic because chlorine can be used as a chemical weapon. Sodium chloride is essential for life. Chlorine kills. Benzene is super hazardous. This tells you absolutely nothing about the hazards of benzoates”…
To pick up on this, when Mr Leyland suggests that chlorine kills it is also an element which is essential for life, it is just that culturally we have come to be affected more by the information that chlorine was used as a gas weapon, for example in the first world war. But this element of the periodic table plays a vital role in our health and wellbeing, as correctly he points out does sodium. Chlorine performs a vital function in the exchange of chloride and bicarbonate across the red blood cell (erythrocyte) membrane (the chloride shift). In its pure gas form it is indeed poisonous.
Without venturing too deeply into syllogisms and logical fallacies, the point which was made needs disambiguating (clarified). If sodium chloride (table salt) were put into some food stuff that had the potential to liberate the chlorine gas, it would be a matter of legitimate concern to investigate.
Salts of compounds sometimes change the action of their component parts in biological systems but sometimes they do not, so investigating further is a worthwhile investment of time.
Sodium acetylsalicylate the sodium salt of acetylsalicylate is still biologically a useful drug – it is just another form of aspirin. A salt in chemistry is an ionic compound that can be formed by the reaction of an acid and an alkali.
Making an assumption is to base decisions on what is not known. If there is a situation where assumptions are temporarily useful, it might be in the precautionary principle which is commonly used in health and wellbeing contexts whilst an investigation takes place…
The important point being made here that it is important to clarify what you are studying by supplementing what you know already… So, benzoates have in them benzene which can be released when benzoates (i.e. sodium benzoate, potassium benzoate) are exposed to commonly occurring substances – specifically vitamin C, copper and iron which are essential and common nutrients in everyone’s diet.
Here is a paper published in the Journal of Agricultural and Food Chemistry illustrating how the production of benzene occurs from benzoates such as sodium benzoate:
“The present study shows that hydroxyl radical, generated by the metal-catalyzed reduction of 02 and H202 by ascorbic acid, can attack benzoic acid to produce benzene under conditions prevalent in many foods and beverages. Since benzene has been shown to be carcinogenic its potential formation in foods during processing and storage should be of some concern”
Gardner, L.K.; Lawrence, G.D. (May 1993). “Benzene Production from Decarboxylation of Benzoic Acid in the Presence of Ascorbic Acid and a Transition-Metal Catalyst”. J. Agric. Food Chem. 41 (5): 693–695. doi:10.1021/jf00029a001
A key principle of the matter should be about focusing on amassing robust evidence and research to learn from the published peer reviewed science out there. The chemistry is understandable and if you dont want to venture into the breakdown chemistry you can always just look up the specific material data safety sheet.
We can logically deduce precautionary safety protocols as well as dispel concerns… So if you have a diet which does not contain ascorbic acid (vitamin C), copper and iron; or if you do have a diet which has these things in but think you can keep those separate from the foodstuffs which have benzoates in them, then you may just want to pay attention to the legislation linked safety information for the chemical itself – in this situation we are looking at Sodium Benzoate…
As you can find in the Material Data Safety Sheet on Sodium Benzoate available above:
Section 3: Hazards Identification
Potential Acute Health Effects: Hazardous in case of skin contact (irritant), of eye contact (irritant), of inhalation. Slightly hazardous in case of ingestion. Potential Chronic Health Effects:
CARCINOGENIC EFFECTS: Not available.
MUTAGENIC EFFECTS: Not available.
TERATOGENIC EFFECTS: Classified POSSIBLE for human.
DEVELOPMENTAL TOXICITY: Classified Reproductive system/toxin/female, Reproductive system/ toxin/male [SUSPECTED].
The substance may be toxic to blood, the reproductive system, liver, central nervous system (CNS). Repeated or prolonged exposure to the substance can produce target organs damage.
Section 11: Toxicological Information
Special Remarks on Chronic Effects on Humans: May cause adverse reproductive effects and birth defects (teratogenic). May affect genetic material (mutagenic)
Special Remarks on other Toxic Effects on Humans: Acute Potential Health Effects: Skin: May cause skin irritation. Eyes: Dust may cause mechanical Inhalation: May cause respiratory tract irritation. Ingestion: Ingestion of large amounts may cause gastrointestinal tract irritation with gastric pain, nausea, and vomiting. May also affect behavior/central nervous system (tremor, convulsions, change in motor activity), and respiration (dyspnea).
Chronic Potential Health Effects: Ingestion: Prolonged or repeated ingestion may affect behavior/central nervous system (sypmptoms similar to acute exposure) as well as liver, metabolism, blood, and urinary system.
So, now you have read the discussion about sources of benzene, benzoates and sodium benzoate, are you in a better position to make your own informed decision about whether you want this in your food ?
Take Home Message
Key in all of this article is that the science is understandable and it is available in libraries and peer reviewed journals online, and even sometimes linked to in wikipedia articles (if you check the references as the source of information).
Make your own notes and write down where you drew your notes from. Knowledge is not just for some people as some might have you believe; anyone can come to grips with tried and tested information with a little effort. Avoid pseudoskepticism and try to engage with genuine thinkers and educators.
Investigate, investigate, investigate
It can be confusing trying to understand what is an impartial source of information on these matters. So for many people who did not want to read the book or invest in understanding the science, I wrote a list out of all the food additives which were banned by one or more country (at the time of publishing, 1987) which formed the original basis of this article.
This made a simple and conservative list to give people to consider removing from the diet. E For Additives is a good book and an interesting one to pick through as a reference. Even though it is an old book, a great deal of the science is still the same. Legislation sometimes does change but it is very rare, if known at all, that something has been banned from the food chain before being put back in by a countrys administration. I would certainly like to know of any cases.

Even better is if you develop an enjoyment of the science, it’s not that hard to pick up and quite interesting to read about the tests which have been done and the things which are generally agreed about. Once you look up what a word means once it is often with you for life, things become a bit easier once you have done some decoding.
For example: Carcinogenic = causes cancer, Teratogenic = halt the pregnancy or produce a congenital malformation (causes birth defects); it is just a matter of getting the lingo. You can draw your own conclusions from there, you dont need a diploma from a medical school to understand this.
Once you start understanding some of the principles which are known you can start looking up the meanings of words and then searching for published peer reviewed papers on the internet and making your own notes.
The media is not accountable but the work of the likes of Professor Denis Corbet is. What I mean by this is that we can look up the documented investigations and thoughts of Prof Corbet by his published work. The media offers no connection to the deep information beyond a small sound bite:
Due to the technology of the internet and the widespread availability of sources of peer reviewed publishing, all we need to do is put the following into google: “Denis Corpet nitrate cancer + filetype:pdf” – which will return the whole papers for us to download. The second result offers us his work to read for ourselves:
