Artificial additives do not turn up in food because shoppers need them but because the food industry needs them for economic reasons. While it is understandable that manufacturers should want to profit from their business, the liberal use of colourings, flavourings and preservatives has gone too far. Additives are in much of the food targeted at children. They warp the concept of natural taste, inducing ignorance of the real thing. They have been proven to alter behaviour, and some are known allergens.

Additives are divided into various categories. The largest groups are colours, preservatives, antioxidants, sweeteners, emulsifiers, gelling agents, stabilisers and thickeners. Then there is a smaller number each of acids, acidity regulators, anti-caking agents, anti-foaming agents, bulking agents, carriers and carrier solvents, emulsifying salts, firming agents, flavour enhancers, flour treatment agents, glazing agents, humectants, modified starches, packaging gases, propellants, raising agents and sequestrants.

The food industry is preoccupied with using appearance to attract customers, and also with the stability of food and its shelf life. It is unfair to blame only the manufacturers when retailers are after the same thing. Shoppers do not ask, however, for the plethora of innovations that appear on shelves on a daily basis. The food industry will always say it is supplying demand, identifying what shoppers want. I think this is rubbish. Supermarkets in particular have created a demand, identifying a weakness for novelty in bored supermarket shoppers (and especially their children), and have risen to it with some alarming imaginings. ‘Meal solutions’, they call them – but have you ever heard someone say, ‘What I really need is a Thai spiced shepherd’s pie topped with a feta cheese and ginger parsnip mash’?

Ready-made food can be great – if it is made with good-quality ingredients and nothing else. Even a sausage needs no more than salt as a preservative. However, it will have a shorter shelf life, and buying additive-free food means shopping more frequently – although I make good use of a small chest freezer for bread, sausages and baked things.

Additives are listed on labels, either in code as E numbers, with their industry name, or – if permitted – a common name. This can be confusing. For example, a label can show monosodium glutamate, flavour enhancer or E621 – these are all the same additive.

Manufacturers use different names for additives such as monosodium glutamate because they are controversial. Flavour enhancer sounds so great, don’t you think? The flavour of your food has been enhanced. Terrific, you think, just what it needs. But it doesn’t – or it wouldn’t if the manufacturers used ingredients with real flavour. A ready-meal maker’s greatest ambition is to put as much water and other cheap ingredients such as modified maize starch as possible into a recipe, and they get away with it by tipping in salt, flavourings, colour, gelling agents, stabilisers, emulsifiers, in fact anything that will hide the fact that these bulk ingredients have no texture or flavour.

The organic sector uses some additives, although nothing like as many as conventional manufacturers. Under the Soil Association’s standard, organic producers can use 30 additives (the EU permits 35) including gum fillers, emulsifiers, preservatives and one colour (annatto).

There is a gaping discrepancy between parents’ anecdotes about the effect of additives on their children and the constant reassurance from the industry that these additives are non-toxic. But the point is missed. The kind of reactions seen in children to certain colours, flavourings, sweeteners and preservatives are allergic reactions, and food additives are tested only for toxicity. In 2002 a government-sponsored study monitored 277 three-year-olds from the Isle of Wight for the effects of additives, which were given in orange juice along with placebos. Many parents of children given additives reported significant changes in mood and behaviour. The additives tested included the artificial food colourings tartrazine (E102), sunset yellow (E110), carmoisine (E122), and ponceau 4R (E124), plus the preservative sodium benzoate (E211). Test doses were well below the levels permitted in children’s foods and drinks yet still the allergic reaction certain children showed was significant. But while the authorities commissioned another report, insisting this one was inconclusive, it is noticeable that manufacturers have mostly removed the ‘Filthy Five’ from children’s food.

Not all E-numbered additives are bad. Some, such as ascorbic acid (E300), are simply vitamin C. E-numbers are additives approved by the EU and their effects on our bodies vary.

With the exception of the glutamate family (E621–633), flavourings do not need ‘E’ approval. With natural flavouring, this is fine but flavourings fall into three interesting categories:

• Artificial – chemical imitations of real flavours.

• Nature identical – nice euphemism, where the actual chemicals present in real flavours are extracted to make flavourings.

• Natural – real essences and dried flavours.

When shopping, bear the following in mind as you read labels: if a manufacturer has added flavourings and colourings, the other ingredients are substandard. Avoid such foods if you can.
