E NUMBERS IN FOOD: HOW TO READ LABELS AND CHECK ADDITIVES BEFORE BUYING
More and more people are turning packages over before buying and reading the ingredient list. The reason is not just curiosity, but also the desire to better understand what we eat every day. Supermarket shelves are filled with a wide range of industrially produced foods, from baked goods and ready made sauces to sweets, snacks, dairy desserts, and drinks. In such products, E numbers in food often appear, meaning labels for food additives that serve a specific technological purpose.
For many consumers, E numbers can be confusing. Some immediately associate them with something artificial or harmful, while others do not know at all what E numbers on a label actually mean. The truth is usually more nuanced. Not every E number is cause for concern, and the mere presence of an additive does not automatically mean that a product is poor quality or unsafe. In some cases, these are well known and common substances such as citric acid, pectin, or ascorbic acid.
That said, food labels should not be ignored. It is useful to understand why food additives are used, how to recognise when a product is highly processed, and when a particular ingredient deserves closer attention. The most important thing is not to jump to conclusions simply because one E number appears on the ingredient list, but to check the specific additive, its function, and any notes that may matter for sensitive individuals, vegetarians, vegans, or parents choosing food for children.
WHAT ARE E NUMBERS?
E numbers are codes used for food additives that are approved for use in food within the European Union. The letter E stands for the European designation, and the number that follows refers to a specific substance or group of substances. This labelling system was introduced so that additives could be clearly identified on food labels, regardless of whether the manufacturer uses the full name of the substance or its shorter code.
Food additives are added to food for technological reasons. They may be used to preserve colour, improve texture, regulate acidity, thicken, stabilise, preserve, prevent spoilage, or maintain consistent product quality. In other words, E numbers are not a special category of food, but a way of identifying substances that perform a specific function in a product.
It is important to understand that additives can come from different sources. Some are naturally derived, some come from plant or animal sources, and some are synthetically produced. The fact that an additive is marked with an E number does not by itself say enough about whether it should be avoided. To understand it properly, you need to look at which additive it is, what food it is used in, how often that type of food is eaten, and whether the person consuming it has any particular sensitivity.
WHY ARE ADDITIVES ADDED TO FOOD?
Food additives are most often used because manufacturers want to create a stable, safe, and technologically consistent product. For foods that must sit on shelves, move through distribution, and retain certain qualities until the expiry date, this can be an important part of production. For example, preservatives can slow spoilage, antioxidants can help protect a product from oxidation, and stabilisers can prevent ingredients from separating.
One of the main reasons for using additives is to extend shelf life. This is especially important for products that are not consumed immediately after production. Additives can help bread stay soft for longer, prevent a sauce from changing texture, keep a drink’s colour stable, or stop fats in a product from going rancid too quickly. In such cases, the additive has a clear technological role.
Another common reason is to preserve or enhance colour. Consumers often expect a product to look familiar and appealing. Fruit yoghurts, sweets, ice creams, drinks, and desserts often contain colourings because the manufacturer wants the product to have a uniform appearance. This does not mean every colouring is problematic, but with intensely coloured foods, especially those frequently consumed by children, it is worth paying attention and checking the specific E numbers.
Additives are also used to improve texture. Thickeners, emulsifiers, and stabilisers can make a product creamier, thicker, smoother, or easier to spread. In industrial production, this is often important because the product needs to remain consistent from one batch to the next. Without such ingredients, some products would not look, last, or behave in the way consumers expect.
In some products, additives are used to enhance or regulate flavour. Flavour enhancers, acidity regulators, and sweeteners can change the overall taste experience, reduce the need for sugar, or tailor flavour to a target group of consumers. Still, when a product has a very long ingredient list and many different additives, it is worth pausing and asking how processed that food is and how often it features in your diet.
DOES AN E NUMBER AUTOMATICALLY MEAN AN ADDITIVE IS HARMFUL?
No. An E number does not automatically mean an additive is harmful. This is one of the most common misconceptions about food additives. An E code is above all a labelling system. On its own, it does not tell you whether a substance is natural, synthetic, potentially problematic for sensitive individuals, or perfectly common in an everyday diet. That is why it is important to look at the specific additive, rather than reacting simply to the presence of the letter E on the label.
Examples of well known substances that can carry E numbers show why it is unwise to draw quick conclusions. Citric acid, ascorbic acid, pectin, and curcumin sound familiar to many people and do not trigger the same reaction as an unfamiliar number code. Citric acid is associated with citrus fruits and a tangy taste, ascorbic acid with vitamin C, pectin with fruit and gelling, and curcumin with the pigment found in turmeric. Yet all of these substances may appear as additives with E codes.
The issue often lies in the context. Quantity matters, frequency of consumption matters, the type of product matters, and the overall quality of the diet matters. Someone who occasionally eats a product with one or two additives is not in the same position as someone whose diet is based every day on highly processed foods, sugary drinks, snacks, ready meals, and desserts with long ingredient lists.
Individual sensitivity also varies from person to person. Some additives may be problematic for sensitive individuals, people with allergies, intolerances, or specific health conditions. For that reason, the best approach is calm and informed: there is no need to panic over every label, but there is also no reason to ignore an ingredient list packed with unfamiliar substances.
WHEN IS IT WORTH PAYING ATTENTION TO E NUMBERS?
It is especially worth paying attention to E numbers when a product has a very long ingredient list. A long label does not always mean a product is poor quality, but it often points to a higher degree of processing. If the list includes numerous colourings, preservatives, sweeteners, flavour enhancers, stabilisers, and emulsifiers, it is wise to take a step back and consider how often that product belongs in your diet.
Products that children consume frequently deserve particular attention. These may include sweets, fizzy drinks, coloured juices, snacks, brightly coloured desserts, breakfast cereals, and various children’s products marketed as fun or convenient. Children often eat the same products repeatedly, and eating habits are formed early. There is no need to create fear, but it is sensible to check what is in the products that are bought regularly.
People with allergies, intolerances, or sensitivities should be especially careful. In such cases, food labels are not just information, but an important tool for everyday decision making. If someone knows they react to certain ingredients, preservatives, colourings, or sweeteners, checking E numbers can help them avoid products that might cause discomfort.
It is also worth paying attention to products that look simple or natural on the front of the packaging while the ingredient list is actually quite complex. Terms such as “natural,” “homemade,” “traditional,” or “fruit flavoured” do not always say enough about the composition. The real information is on the label, and E numbers on food labels can provide useful clues to what is truly in the product.
E NUMBERS AND LABELS: HOW TO READ THEM IN THE SHOP
When reading a label in the shop, first look at the order of ingredients. Ingredients are usually listed by quantity, from the most abundant to the least. If sugar, glucose syrup, vegetable oils, starch, or other heavily processed ingredients appear near the top of the list, that tells you more about the product than a single E number at the end of the label.
Next, assess how processed the product is. A simple label with a few understandable ingredients is often easier to evaluate. On the other hand, a long ingredient list containing several additives, flavourings, thickeners, and sweeteners may point to a more technologically complex product. This does not mean you should never buy it, but it does mean it is worth understanding what you are choosing.
The third step is to pay attention to the number of additives. There is a difference between a product containing one additive with a clear function and one containing a whole string of different additives. If you see several E codes in a row, do not automatically assume the product is harmful, but it is worth checking what those substances are. Sometimes they are common acidity regulators or thickeners, and sometimes they are colourings, preservatives, or sweeteners that you may want to look into more closely.
It is important not to draw conclusions based on a single E number alone. One additive can have different roles in different products, and the overall assessment depends on the entire label. For example, a product may contain one familiar additive yet still have a generally simple composition. Another product may highlight that it contains no particular additive, while still being loaded with sugar, salt, fat, or other ingredients that are best limited in large amounts.
Comparing similar products is a very practical habit. If you are choosing between two yoghurts, two sauces, two types of bread, or two kinds of sweets, look at the labels side by side. You will often quickly see which product has a shorter ingredient list, fewer additives, or more clearly stated ingredients. Whenever possible, choose simpler labels, especially for foods you buy often.
If you come across an unfamiliar E number, the best approach is to check it before buying, or at least before making the product part of your regular diet. Checking E numbers does not have to be complicated. It is enough to know that the code stands for a specific additive and that proper understanding comes from looking at that additive itself, rather than making a sweeping judgement about all E numbers.
DO SOME E NUMBERS CONTAIN ANIMAL DERIVED INGREDIENTS OR INSECTS?
Yes, some food additives may be of animal origin or derived from insects. This does not mean that all such additives are harmful, but this information matters to people who want to know where ingredients come from. It is especially important for vegetarians, vegans, people who monitor food composition for religious reasons, and anyone who wants to make more conscious product choices.
One of the better known examples is E120 carmine, also known as cochineal. This is a colouring obtained from insects and used to create red or pink shades in certain products. A consumer who only sees the red colour of a product cannot know the origin of the colouring without reading the label. That is why checking the ingredient list is particularly important if you avoid animal derived ingredients for ethical, dietary, or religious reasons.
It is neither practical nor necessary to try to memorise every additive of animal origin. Product formulations change, ingredients may be listed in different ways, and the same type of product can have a different recipe depending on the manufacturer. That is why it is better to build the habit of checking a specific E number when you see it on a label. In this, an E number and food additive search tool can be helpful, especially when you want to quickly learn more about a particular additive.
WHY IS IT NOT ENOUGH TO MEMORISE ONLY A FEW “BAD” E NUMBERS?
Many consumers try to memorise a few additives they have heard described as problematic. That approach may seem simple, but in practice it is not reliable enough. First, product formulations change. A manufacturer may alter a recipe, replace one additive with another, or list ingredients differently. What you learned about one product last year may no longer apply today.
Second, the same additive can play a different role in different products. In one product it may serve as a stabiliser, in another as an acidity regulator, and in a third as a colouring or texture agent. Assessment therefore depends not only on the additive’s name, but also on the type of food, the quantity, the frequency of consumption, and your personal needs.
Third, labels can be confusing for consumers. Sometimes the E number is listed, and sometimes the full name of the additive is given. The same substance may seem more unfamiliar when written as a numerical code and more acceptable when written out by name. That is why lists of “good” and “bad” additives often oversimplify the subject more than they truly help.
Fourth, focusing only on a few harmful additives can distract from the overall quality of the diet. A product may be free from a certain additive and still be very sugary, salty, fatty, or low in nutritional value. On the other hand, a product may contain one technologically justified additive and still fit reasonably well into a balanced diet.
That is why it is more practical to check a specific additive at the moment you see it on a label. This approach does not require memorising long lists, but instead builds the habit of making informed choices. Rather than asking, “Are all E numbers bad?” it is more useful to ask, “What is this additive, why is it in the product, and is there anything important I should know about it for my own needs?”
HOW CAN YOU QUICKLY CHECK A SPECIFIC E NUMBER?
When you see a code on a label that you do not recognise, the simplest approach is to check that exact additive. Instead of guessing or relying on unreliable lists online, you can enter or select the specific E number and review information about the additive in question. This is especially useful in the shop, when you want to assess a product quickly before buying.
For this purpose, you can check E numbers in the ExposeLife search tool. This tool is useful as the next step after reading a label: first you identify the E number on the product, then you check what additive it refers to. That way, you do not have to memorise a large number of codes or make decisions based only on first impressions.
Checking is particularly useful for products you buy often, foods for children, products with long ingredient lists, or additives you are seeing for the first time. It can also help people who monitor animal derived additives, colourings, sweeteners, or preservatives. The aim is not to create fear around every label, but to support calmer and better informed decisions.
It is worth remembering that a checking tool does not replace reading the full label. It helps you understand a particular additive, but it is still important to look at the product as a whole. Ingredients, nutritional values, portion size, and frequency of consumption together give a clearer picture than one code taken out of context.
HOW TO REDUCE YOUR INTAKE OF UNNECESSARY ADDITIVES
The first step is to choose less processed food whenever possible. Fresh fruit and vegetables, whole grains, legumes, nuts, eggs, fish, meat, yoghurt, fresh cheese, and simple staple ingredients usually have shorter and more understandable labels, or no long ingredient list at all. This does not mean ready made products should never be bought, but it does mean that it is wise to build the foundation of your diet around simpler foods.
Cooking at home can also reduce your intake of unnecessary additives. When you prepare soup, sauce, spread, dessert, or a meal yourself, you have better control over the ingredients. You do not have to do everything perfectly or always cook from scratch, but even a few homemade meals a week can make a difference to the overall quality of your diet.
Comparing labels on similar products is a very simple yet useful habit. If two products have a similar price and purpose, choose the one with the shorter and clearer ingredient list, especially if you buy it regularly. With occasional products, you can take a more relaxed approach, but in everyday choices small differences matter.
Pay special attention to products for children. Children’s foods, sweets, drinks, and snacks often come in attractive packaging, bright colours, and with messages that create the impression that the product is designed for children. Still, the front of the packaging is there to sell, while the real information is on the label. If a child eats the same product often, it is worth checking its composition.
Do not automatically buy a product just because it says “natural.” The term may sound appealing, but it does not always say enough. A natural origin does not automatically mean something is always suitable for every person and in every quantity. By the same token, a synthetic origin does not automatically mean something is harmful. What matters is the specific ingredient, the amount, the purpose, and the context.
Use reliable sources for information about additives. Instead of relying on alarming posts or incomplete lists, it is better to use a tool designed specifically for checking individual codes. If you want to know more about a particular ingredient, an additive check by E number can be a simple way to quickly access useful information.
Most importantly, do not panic. Learn how to read labels instead. The more often you look at ingredient lists, the easier it becomes to recognise patterns. Over time, you will more quickly spot the difference between a simple label, a product with a few technologically standard additives, and a product with a very long ingredient list that you may prefer not to buy often.
THE MOST COMMON MISCONCEPTIONS ABOUT E NUMBERS
The first misconception is: “All E numbers are harmful.” That is not true. E numbers are a labelling system for food additives, and they include very different substances. Some are well known and commonly used, some are naturally derived, some are synthetic, and some deserve closer attention. That is why it is not helpful to place them all in the same category.
The second misconception is: “If something is natural, it is always safe.” Natural does not automatically mean suitable for every person, in every quantity, and in every product. Some natural substances can trigger allergic reactions or discomfort in sensitive individuals. What matters is knowing what the substance is, rather than relying solely on the impression created by the word “natural.”
The third misconception is: “If there are no E numbers, the product is automatically healthy.” That is not necessarily true either. A product may contain no E codes at all and still be high in sugar, salt, saturated fat, or refined ingredients. A healthier choice depends not only on the absence of E numbers, but on the overall composition, nutritional value, and the role the product plays in your diet.
The fourth misconception is: “It is enough to memorise a few dangerous additives.” In practice, that is unreliable. Formulations change, labels may differ, and individual additives can serve different purposes. Rather than memorising lists, it is more useful to build the habit of reading the label and checking a specific E number whenever a question arises.
The fifth misconception is: “All additives are artificial.” That is not true either. Food additives may be of natural, animal, plant, mineral, or synthetic origin. Sometimes an additive is obtained from a natural source, and sometimes it is produced industrially in order to ensure stable quality and function. Origin can matter, but on its own it is not the only criterion for assessment.
That is exactly why it is helpful to approach the subject calmly. E numbers in food are not a simple division between good and bad. They are part of a broader story about the food industry, shopping habits, labelling, and personal needs. Whenever something is unclear, it is best to learn more about a specific E number instead of relying on assumptions.
E NUMBERS ARE NOT A REASON TO PANIC, BUT THEY ARE WORTH UNDERSTANDING
E numbers are part of the modern food industry and appear in many products we come across every day in shops. Their role can vary: preserving shelf life, stabilising, thickening, regulating acidity, improving texture, or enhancing colour. For that reason, it is not enough to simply see an E number and conclude that a product is harmful.
Not all E numbers are harmful, but some do deserve extra attention. It is especially wise to be cautious with highly processed foods, products with very long ingredient lists, foods that children consume often, and products intended for people with allergies, intolerances, or specific dietary rules. Additives of animal origin, such as the well known example E120 carmine, may also matter to those who pay attention to where ingredients come from.
Labels should be read as a whole. The order of ingredients, the number of additives, the type of product, the nutritional values, and the frequency of consumption together provide a fuller picture. One E number may not mean much on its own, but it can be a prompt to better understand what you are buying.
The best approach is to make informed food choices. That means less fear and more knowledge. Choose simpler products when you can, compare labels, do not rely only on the front of the packaging, and do not try to memorise long lists of additives. When you want to know more about a specific ingredient, the best step is to check the specific E number before buying and decide based on clearer information.
