Christopher Snowden responds to some of the claims in Chris van Tulleken’s book Ultra-Processed People: Why Do We All Eat Stuff That Isn’t Food … And Why Can’t We Stop?:
Ultra-processed food (UPF) is the latest bogeyman in diet quackery. The concept was devised a few years ago by the Brazilian academic Carlos Monteiro who also happens to be in favour of draconian and wildly impractical regulation of the food supply. What are the chances?!
Laura Thomas has written some good stuff about UPF. The tldr version is that, aside from raw fruit and veg, the vast majority of what we eat is “processed”. That’s what cooking is all about. Ultra-processed food involves flavourings, sweeteners, emulsifiers etc. that you wouldn’t generally use at home, often combined with cooking processes such as hydrogenation and hydrolysation that are unavailable in an ordinary kitchen. In short, most packaged food sold in shops is UPF.
Does this mean a cake you bake at home (“processed”) is less fattening than a cake you buy from Waitrose (“ultra-processed”)? Probably not, so what is the point of the distinction? This is where the idea breaks down. All the additives used by the food industry are considered safe by regulators. Just because the layman doesn’t know what a certain emulsifier is doesn’t mean it’s bad for you. There is no scientific basis for classifying a vast range of products as unhealthy just because they are made in factories. Indeed, it is positively anti-scientific insofar as it represents an irrational fear of modernity while placing excessive faith in what is considered “natural”. There is also an obvious layer of snobbery to the whole thing.
Taken to an absurd but logical conclusion, you could view wholemeal bread as unhealthy so long as it is made in a factory. When I saw that CVT has a book coming out (of course he does) I was struck by the cover. Surely, I thought, he was not going to have a go at brown bread?
But that is exactly what he does.
During my month-long UPF diet, I began to notice this softness most starkly with bread — the majority of which is ultra-processed. (Real bread, from craft bakeries, makes up just 5 per cent of the market …
His definition of “real bread” is quite revealing, is it not?
For years, I’ve bought Hovis Multigrain Seed Sensations. Here are some of its numerous ingredients: salt, granulated sugar, preservative: E282 calcium propionate, emulsifier: E472e (mono- and diacetyltartaric acid esters of mono- and diglycerides of fatty acids), caramelised sugar, ascorbic acid.
Let’s leave aside the question of why he only recently noticed the softness of fake bread if he’s been eating it for years. Instead, let’s look at the ingredients. Like you, I am not familiar with them all, but a quick search shows that E282 calcium propionate is a “naturally occurring organic salt formed by a reaction between calcium hydroxide and propionic acid”. It is a preservative.
E472e is an emulsifier which interacts with the hydrophobic parts of gluten, helping its proteins unfold. It adds texture to the bread.
Ascorbic acid is better known as Vitamin C.
Caramelised sugar is just sugar that’s been heated up and is used sparingly in bread; Jamie Oliver puts more sugar in his homemade bread than Hovis does.
Hovis Multigrain Seed Sensations therefore qualifies as UPF but it is far from obvious why it should be regarded as unhealthy. According to CVT, the problem is that it is too easy to eat.
The various processes and treatment agents in my Hovis loaf mean I can eat a slice even more quickly, gram for gram, than I can put away a UPF burger. The bread disintegrates into a bolus of slime that’s easily manipulated down the throat.
Does it?? I’ve never tried this brand but it doesn’t ring true to me. It’s just bread. Either you toast it or you use it for sandwiches. Are there people out there stuffing slice after slice of bread down their throats because it’s so soft?
By contrast, a slice of Dusty Knuckle Potato Sourdough (£5.99) takes well over a minute to eat, and my jaw gets tired.
Far be it from me to tell anyone how to spend their money but, in my opinion, anyone who spends £6 on a loaf of bread is an idiot. Based on his description, the Dusty Knuckle Potato Sourdough is awful anyway. Is that the idea? Is the plan to make eating so jaw-achingly unenjoyable that we do it less? Is the real objection to UPF simply that it tastes nice?
