What Is Ultra-Processed Food? UK List & Scanner

Q: What is ultra-processed food?

Ultra-processed food (UPF) is a term from the NOVA classification system for foods that have been industrially manufactured using ingredients and processes you wouldn't find in a home kitchen. They typically contain additives like emulsifiers, flavourings, colourings, and sweeteners designed to make products hyper-palatable, convenient, and long-lasting. Common examples include fizzy drinks, mass-produced bread, instant noodles, and most packaged snacks.

Q: Is all processed food bad?

No. Processing itself is not harmful — cooking, freezing, fermenting, and tinning are all forms of processing that can preserve nutrients and make food safer. The NOVA system distinguishes four levels: unprocessed foods, processed culinary ingredients (oil, butter, sugar), processed foods (tinned vegetables, cheese, fresh bread), and ultra-processed foods. Only the last category — Group 4 — raises health concerns in research. Tinned tomatoes, frozen peas, and traditionally made cheese are all processed but nutritionally sound.

Q: What percentage of UK food is ultra-processed?

Research published in the BMJ and by the National Diet and Nutrition Survey estimates that approximately 57% of calories consumed in the UK come from ultra-processed foods. This is one of the highest proportions in Europe. The figure is even higher among children and young people, and among lower-income households where UPF tends to be more affordable.

Q: How do I check if a food is ultra-processed?

Read the ingredient list and look for substances you wouldn't use at home: high-fructose corn syrup, hydrogenated oils, modified starches, protein isolates, flavourings, emulsifiers, and colour additives. If the list is long and contains unfamiliar chemical-sounding names, the product is likely ultra-processed. You can also scan the barcode with the NutraSafe app, which identifies additives and E-numbers instantly.

Q: Are all E-numbers ultra-processed?

No. E-numbers are simply a European coding system for approved food additives, and many are entirely natural. E300 is vitamin C, E330 is citric acid (found naturally in lemons), and E160a is beta-carotene from carrots. However, a long list of E-numbers on a product often indicates a high degree of industrial processing. The presence of emulsifiers, artificial sweeteners, or synthetic colourings is a stronger indicator of ultra-processing than E-numbers alone.

Q: Is sourdough bread ultra-processed?

Traditional sourdough bread made with flour, water, salt, and a natural starter culture is not ultra-processed — it falls into NOVA Group 3 (processed food). However, some mass-produced supermarket breads labelled 'sourdough' contain added emulsifiers, preservatives, dough conditioners, and flavourings, which would make them ultra-processed. Check the ingredient list: genuine sourdough should have very few ingredients.

Q: Can an app tell me if food is ultra-processed?

Yes. Apps like NutraSafe let you scan a barcode and instantly see all additives, E-numbers, and ingredients in a product. While no app can definitively classify every food under the NOVA system (which requires expert judgement), a barcode scanner can quickly reveal the hallmarks of ultra-processing: long ingredient lists, industrial additives, and unfamiliar substances. This gives you the information to make your own informed decision.

Q: What does the NHS say about ultra-processed food?

The NHS acknowledges the growing body of research linking high consumption of ultra-processed foods to health concerns including obesity, type 2 diabetes, and cardiovascular disease. The NHS Eatwell Guide recommends a diet based on whole grains, fruit, vegetables, and lean protein — which naturally limits UPF intake. The Scientific Advisory Committee on Nutrition (SACN) has also reviewed evidence on UPF and health outcomes as part of its ongoing advisory work.

Quick Answer

Ultra-processed food (UPF) is food that has been industrially manufactured using ingredients and techniques you would not find in a home kitchen — things like hydrogenated oils, modified starches, flavourings, emulsifiers, and artificial sweeteners. In the UK, an estimated 57% of daily calories come from ultra-processed products. Common examples include fizzy drinks, mass-produced sliced bread, instant noodles, crisps, and most ready meals.

The NOVA Classification: Understanding the Four Groups

The term "ultra-processed" comes from the NOVA classification system, developed by Professor Carlos Monteiro and colleagues at the University of Sao Paulo, Brazil. NOVA sorts all foods into four groups based on the extent and purpose of processing — not their nutritional content. It has since been adopted by researchers worldwide, including those advising the UK Food Standards Agency and the World Health Organization.

Unprocessed or Minimally Processed

Fresh fruit and vegetables, eggs, plain milk, fresh meat, fish, nuts, seeds, grains, herbs, spices, plain yoghurt. Foods in their natural state, or simply dried, chilled, frozen, or pasteurised.

Processed Culinary Ingredients

Butter, oils, sugar, salt, honey, vinegar, flour. Substances extracted from Group 1 foods, used in home cooking rather than eaten alone.

Processed Foods

Tinned vegetables, traditionally baked bread, real cheese, smoked fish, cured meats, pickled onions, salted nuts. Group 1 foods modified using Group 2 ingredients — recognisable, with short ingredient lists.

Ultra-Processed Foods (UPF)

Industrially manufactured products with long ingredient lists including additives, flavourings, emulsifiers, colourings, and sweeteners designed to create hyper-palatable, convenient, long-lasting products. This is the group that research links to health concerns.

The key distinction is this: processed foods (Group 3) are recognisable versions of whole foods. Ultra-processed foods (Group 4) are industrial formulations — the ingredients list reads like a chemistry set rather than a recipe.

Common Ultra-Processed Foods in UK Supermarkets

The following are everyday products found on UK shelves that fall into NOVA Group 4. This is not a list of foods to fear — it is a guide to help you recognise what counts as ultra-processed, so you can make choices that suit your own health goals.

Breakfast Cereals

Coco Pops, Frosties, Crunchy Nut
Flavoured granola with added oils
Instant porridge sachets with flavourings
Cereal bars and breakfast biscuits

Bread & Bakery

Mass-produced sliced bread (most brands)
Wraps with emulsifiers and preservatives
Packaged crumpets and muffins
Hot dog and burger buns

Ready Meals & Convenience

Microwave meals and frozen pizzas
Pot Noodles and instant noodles
Chicken nuggets and fish fingers
Frozen chips with added coatings

Snacks & Confectionery

Crisps and flavoured tortilla chips
Chocolate bars (most mass-produced)
Biscuits, cakes, and doughnuts
Fruit snacks and flavoured rice cakes

Drinks

Fizzy drinks (Coca-Cola, Pepsi, Fanta)
Energy drinks (Monster, Red Bull, Lucozade)
Squash and flavoured water
Sweetened plant milks with additives

Sauces, Spreads & Condiments

Ketchup and brown sauce
Many shop-bought pasta sauces
Margarine and low-fat spreads
Flavoured mayonnaise and dressings

Dairy & Alternatives

Flavoured yoghurts with sweeteners
Processed cheese slices and spreads
Sweetened milkshakes
Ice cream with stabilisers and emulsifiers

Meat & Protein Products

Sausages and hot dogs (most brands)
Bacon with added nitrites and flavourings
Deli meats (ham, salami, turkey slices)
Plant-based burgers and "chicken" pieces

A useful rule of thumb: if the ingredient list contains five or more items you would not keep in your kitchen cupboard — such as modified maize starch, dextrose, maltodextrin, mono- and di-glycerides of fatty acids, or flavourings — the product is very likely ultra-processed. You can use a barcode scanner app to quickly check ingredients on the spot.

Why Ultra-Processed Food Matters for UK Health

The UK is one of the highest consumers of ultra-processed food in Europe. Data from the National Diet and Nutrition Survey suggests that around 57% of calories consumed by UK adults come from ultra-processed products. Among children, the figure is even higher.

A growing body of research, including large studies published in the British Medical Journal (BMJ), has linked high UPF consumption to increased risks of obesity, type 2 diabetes, cardiovascular disease, and certain cancers. A 2024 umbrella review published in the BMJ, which analysed evidence from nearly 10 million participants across multiple studies, found consistent associations between high UPF intake and 32 adverse health outcomes.

It is worth noting that these are associations, not proof of causation. Some researchers argue that the harms may come from poor overall dietary patterns rather than ultra-processing itself. The Food Standards Agency (FSA) and the Scientific Advisory Committee on Nutrition (SACN) have acknowledged the evidence and continue to review the role of UPF in UK diets.

The NHS Eatwell Guide does not use the NOVA classification directly, but its recommendations — eat more fruit, vegetables, whole grains, and lean protein; limit sugary, fatty, and highly processed food — naturally point towards reducing ultra-processed food in your diet.

How to Identify Ultra-Processed Food

You do not need a degree in food science to spot ultra-processed products. Here are practical steps you can use on your next shop.

Read the ingredient list, not just the front label. Marketing terms like "natural," "wholesome," and "made with real fruit" are not regulated and do not rule out ultra-processing.
Look for ingredients you would not have at home. Modified starch, maltodextrin, hydrogenated vegetable oil, high-fructose glucose syrup, protein isolates, flavour enhancers — these are hallmarks of industrial manufacturing.
Count the ingredients. Most whole or processed foods have fewer than five ingredients. Ultra-processed products often have fifteen or more.
Check for E-numbers that indicate additives. While not all E-numbers are harmful (E300 is vitamin C), a cluster of emulsifiers (E471, E472e), stabilisers (E407, E412), and artificial colours (E102, E129) is a strong signal. Learn more in our food additives guide.
Use a barcode scanner. The NutraSafe food scanner instantly identifies every additive and E-number in a product, with plain-language explanations of what each one does.
Compare across brands. Two products that look identical on the shelf can have very different ingredient lists. A shop-bought hummus with chickpeas, tahini, oil, lemon, and garlic is processed (Group 3). One with modified starch, flavourings, and preservatives is ultra-processed (Group 4).

Practical Swaps: Reducing Ultra-Processed Food

You do not need to eliminate UPF entirely — that would be unrealistic for most people. But small, consistent swaps can meaningfully shift the balance of your diet towards less processed options. Here are everyday exchanges that work in the UK.

Flavoured yoghurt with sweeteners → Plain Greek yoghurt with fresh berries

Mass-produced sliced bread → Bakery sourdough or wholemeal bread (check the label)

Sugary breakfast cereal → Porridge oats with banana and nuts

Fizzy drinks and energy drinks → Sparkling water with a slice of lemon or lime

Crisps and flavoured snacks → Nuts, seeds, or apple slices with peanut butter

Shop-bought pasta sauce → Tinned tomatoes, garlic, olive oil, and basil

Processed deli meats → Home-roasted chicken or tinned fish

Margarine or low-fat spread → Butter (in moderation) or extra virgin olive oil

Instant noodles or Pot Noodle → Rice noodles with soy sauce, veg, and an egg

Processed cheese slices → Real Cheddar, Red Leicester, or any block cheese

The goal is not perfection. It is awareness. When you can see what is in your food, you are free to make choices that actually align with what matters to you — whether that is health, taste, cost, or convenience. Use NutraSafe's food diary to track your progress over time and spot patterns you might not notice otherwise.

Frequently Asked Questions

What is ultra-processed food?

Ultra-processed food (UPF) is a category from the NOVA classification system. It refers to industrially manufactured products made primarily from substances derived from foods and additives, with little or no intact whole food. They typically contain ingredients you would not use at home — emulsifiers, flavourings, colourings, hydrogenated oils, and modified starches. Examples include fizzy drinks, packaged snacks, instant noodles, and most ready meals.

Is all processed food bad?

No. Processing is a spectrum. Cooking, freezing, fermenting, and tinning are all forms of processing that can preserve nutrients and make food safer to eat. Tinned tomatoes, frozen peas, cheese, and traditional bread are all "processed" under the NOVA system (Group 3) but are nutritionally sound. The concern centres specifically on ultra-processed foods (Group 4) — products made with industrial ingredients and designed for convenience and long shelf life rather than nutrition.

What percentage of UK food is ultra-processed?

Research based on the National Diet and Nutrition Survey estimates that approximately 57% of calories consumed by UK adults come from ultra-processed foods. The figure is higher among children and young people, and tends to be higher in lower-income households where UPF is often more affordable and accessible. The UK has one of the highest rates of UPF consumption in Europe.

How do I check if a food is ultra-processed?

Read the ingredient list on the back of the packet. Look for ingredients you would not have in your kitchen: modified starch, maltodextrin, hydrogenated fat, protein isolate, flavouring, emulsifier (such as E471 or E472e), and artificial colours. If the list is long and contains unfamiliar substances, the product is likely ultra-processed. You can also use a free barcode scanner like NutraSafe to identify additives instantly.

Are all E-numbers ultra-processed?

No. E-numbers are simply a coding system for approved food additives in the EU and UK. Many are entirely natural: E300 is vitamin C, E330 is citric acid, E160a is beta-carotene. Having an E-number does not make a food ultra-processed. However, a long list of E-numbers — particularly emulsifiers, artificial sweeteners, and synthetic colourings — often indicates a high degree of industrial processing. Our E-numbers database explains each one.

Is sourdough bread ultra-processed?

Traditional sourdough made from flour, water, salt, and a natural starter is not ultra-processed — it is a processed food (NOVA Group 3). However, many mass-produced supermarket breads marketed as "sourdough" contain added emulsifiers, dough conditioners, preservatives, and flavourings, which would place them in Group 4. Always check the ingredient list. Genuine sourdough typically has four or five ingredients at most.

Can an app tell me if food is ultra-processed?

An app can give you the information you need to judge for yourself. NutraSafe scans a product's barcode and shows you every ingredient, additive, and E-number, with clear explanations of what each one is and does. While NOVA classification technically requires expert judgement and cannot be fully automated, seeing the full ingredient list with additives highlighted makes it straightforward to identify ultra-processed products.

What does the NHS say about ultra-processed food?

The NHS acknowledges the growing evidence linking high UPF consumption to adverse health outcomes. The NHS Eatwell Guide recommends a diet based on whole grains, fruit, vegetables, beans, and lean protein — which naturally limits UPF intake. The Scientific Advisory Committee on Nutrition (SACN) has reviewed evidence on ultra-processed food and health, and the Food Standards Agency (FSA) continues to monitor the research as part of its public health remit.
