The Guardian view on ultra-processed food: blame business, not consumers | Editorial

Evidence is mounting on the health costs of these products. The real culprit is financialised growth, not inadequate individual willpower

If we are what we eat, then we are increasingly composed from substances including synthetic emulsifiers, flavour compounds, bulking agents and stabilising gums (one of the most common being a slime produced by bacteria). Well over half of the average diet in the UK and US now consists of ultraprocessed food (UPF) - or, as one scientist prefers to put it, industrially produced edible substances. Though defining it technically is complex, the simple explanation is that it contains items you wouldn't normally find in a kitchen.

Sometimes UPF looks like junk food - obviously artificial and high in salt, fat and sugar. But it often comes in reassuring forms such as soup, muesli or yoghurt. Almost every food that comes with a health claim on the packet is a UPF," notes Dr Chris van Tulleken drily in Ultra-Processed People, one of several recent books on the subject.
