Food can be divided into four categories, from unprocessed to ultra-processed.
Despite being an unfamiliar term, much of what we eat nowadays will fall into the last bracket.
This refers to how much processing your food has gone through in its production, tending to indicate that something will contain additives which are not used in home cooking.
Ultra-processed foods include things you might assume are unhealthy such as crisps and biscuits, but also includes some cereals, bread, and yoghurts.
So what does the term really mean, and are ultra-processed foods bad for you?
Ultra-processed foods include things you might assume are unhealthy such as cake and biscuits, but also includes some cereals, bread, and yoghurts
Crisps are another thing we eat a lot of which is classed as ultra-processed
Fruit and vegetables are at the other end of the food spectrum, as they have been barely altered from their natural state
What are the four food categories?
The NOVA food classification divides foods into four categories based on how much they have been processed in production.
One: Unprocessed and minimally processed
Group one includes foods such as fruit and vegetable, milk, fish, and eggs, which we buy without any ingredients having been added to them, so are very similar to their natural state.
Two: Oils, fats, salt, and sugar
This is also called processed culinary ingredients, and refers to products which have been extracted from natural foods or processes.
This group includes oils made from seeds, butter, and honey.
Three: Processed foods
This is a group of foods which are manufactured by combining members of groups one and two, so includes fresh bread, pickled vegetables, and cured meat.
Four: Ultra-processed foods
These often have five or more constituent ingredients, including additives not used in home cooking.
These additives might include preservatives, emulsifiers, and sweeteners.
How can I know that my food is ultra-processed?
Long lists of ingredients will most often be a sure-fire way of knowing that the food you buy is ultra-processed.
If you have a more detailed look at these ingredients and see things which you do not recognise, or words which you could not pronounce, that is also a good indication.
A long shelf life might also be a sign of ultra-processed food, since this could be down to it containing preservatives.
Finally, check the coloured indicators for sugar, salt, and fat content – ultra-processed foods will often score highly on these.
Are ultra-processed foods bad for you?
These sorts of food often contain high quantities of salt, sugar, and saturated fat, leaving less room for more beneficial ingredients.
There is also a consistent and growing body of research linking higher consumption of ultra-processed foods to negative health outcomes such as cancer.
However, these studies only show a correlation, not a direct causation, with one suggestion that a diet including more ultra-processed foods is just indicative of a more unhealthy lifestyle overall.
What do experts say?
Experts have insisted that there are such things as healthy ultra-processed foods, or at least not unhealthy ones.
Professor Gunter Kuhnle, an expert in nutrition at the University of Reading, criticised the label for being too vague.
He told MailOnline: ‘The problem – especially now with the cost-of-living-crisis – is that people avoid perfectly fine, affordable food because they believe it to be “unhealthy”.
‘We have been seeing the same problem with frozen vegetables – even though they are not ultra-processed, they are for some reason seen as “less healthy”.’
However, TV doctor Chris van Tulleken has dedicated a book to the dangers of ultra-processed foods, or as some call them, ‘industrially produced edible substances’.

He said: ‘These substances can’t even really be called ‘food’. Increasingly, the calories we consume come from modified starches, from invert sugars, hydrolysed protein isolates and seed oils that have been refined, bleached, deodorised and hydrogenated.
‘What this means is that everything from chicken nuggets to ice cream can be made from the same base liquids and powders.’
The British Heart Foundation advise simply focusing on the balance in your diet, rather than cutting out ultra-processed foods entirely.
They highlight that not all ultra-processed foods are equal, with bread largely incomparable to crisps and sweets, despite all falling into the ultra-processed category.
