Creator Chris Van Tulleken is an infectious ailments physician on the College School Hospital in London for Tropical Ailments and an affiliate professor at College School London within the division of an infection. Chris has a medical diploma from Oxford and a PhD in molecular virology.
In his e-book Extremely Processed Folks, he focuses on the query of weight problems with its relation to Extremely Processed Meals (UPF). He supplies a mixture of evaluation and commentary to indicate how UPFs have an effect on the human physique, and the way they’re marketed.
Van Tulleken’s objective is to provide folks data to ‘arm your self with the easy and not-so-simple details that may enable you make the alternatives which might be best for you.’
This Extremely Processed Folks assessment addresses the bigger factors within the e-book.

As a dietitian, I feel ultra-processed meals does have a rightful place in our world. Ought to our diets be made up solely from it? Not ideally. However, I do consider that it’s totally potential to be wholesome and to eat some UPF.
Beginning out, the e-book’s cowl calls UPF ‘meals that isn’t meals.’ Not solely is ultra-processed meals precise meals, it’s generally the one meals people can afford.
Whereas Van Tulleken talks about meals deserts and social determinants of well being all through the e-book, it’s a bit wealthy that the e-book’s cowl would meals disgrace folks earlier than they even open it.
Based on Van Tulleken, over the previous 150 years, now we have begun to devour substances constructed from molecules utilizing a number of sorts of processing. Lots of our energy are coming from elements like modified starches, invert sugars, hydrolyzed protein isolates, and seed oils, and ultra-processed meals now makes up round 60 per cent of the common food regimen within the UK and USA.
Van Tulleken outlines that as time goes on, people are starting to devour increasingly more UPF that in flip, may be dangerous to the physique.
Whereas this can be right, it’s necessary to comprehend the nuance behind meals selections and diet normally: sure, UPF could enhance threat for illness in the event that they’re all persons are consuming.
I’m prepared to enterprise that almost all people on this planet perceive that their whole diets shouldn’t include meals like chips and soda; and, when that is the case, it’s not as a result of the particular person has a selection of what to eat – in lots of instances, they’re attempting to outlive on a restricted meals funds.
There are outliers, in fact, however social determinants of well being are intimately linked to meals selections and in the end, to an individual’s well being standing and outcomes.

A person’s capability to make knowledgeable and wholesome meals selections is closely influenced by a posh interaction of circumstances. These circumstances embody disparities in entry to sources like time, funds, and training.
No, we don’t all have the identical 24 hours in a day. Right here’s why.
Moreover, socioeconomic elements, resembling revenue, training, and dwelling circumstances, can exert a major affect, typically constraining folks to depend on extra handy and processed meals choices.
All of this stuff can affect the quantity of ultra-processed meals somebody eats, and Van Tulleken acknowledges this within the e-book.
NOVA classification
Van Tulleken talks concerning the NOVA classification of UPF. NOVA classification of meals is a standardized technique for categorization of meals, principally for scientific functions.
NOVA classes are:
Group 1: Unprocessed and minimally processed meals
Group 2: Processed culinary elements
Group 3: Processed meals
Group 4: Extremely-processed meals
NOVA is a reasonably fundamental approach of placing meals into unfastened classes, however its usefulness in on a regular basis life is questionable. Its accuracy can also be considerably controversial, because it’s constructed on subjective information. It’s pretty apparent which meals are unprocessed and minimally processed, and hundreds of processed meals like hummus, frozen greens, canned beans, pasteurized milk, and others are nutritious.
We don’t really want NOVA to inform us this.
I wrote extra about NOVA in my publish about ultra-processed meals right here.
Van Tulleken hypothesizes that UPF are engineered to be addictive, which he says complicates issues when somebody is attempting to chop these meals to drop extra pounds. The validity of a ‘meals dependancy’ analysis is controversial: Some folks do have signs that will mimic dependancy however this doesn’t occur with everybody. It’s unknown if these signs are resulting from an precise bodily dependancy.
He talks about how because the 1980’s, the prevalence of weight problems has skyrocketed, which he believes is due to our UPF behavior. Like numerous Van Tulleken’s theories in Extremely Processed Folks, I discover this one to be an oversimplification of a posh difficulty: how can we are saying that weight problems is straight resulting from UPF intakes?
Listed here are another variations between now and the 80’s:
Residence Economics isn’t a lot of a factor in faculties anymore
Immediately, now we have a tradition the place being busy is praised, resulting in elevated stress and nervousness
We’re extra sedentary, particularly with display time and the supply of on-line…every little thing
There’s a larger selection in grocery shops, which might result in elevated consumption
Decreased neighborhood helps
Elevated price of dwelling – The rising price of dwelling, together with bills associated to housing, healthcare, and training, can affect folks’s means to prioritize well being and diet.When people and households face monetary constraints, they might go for cheaper, calorie-dense meals that present short-term satiety however lack important vitamins.
The price of meals has gone up because the Eighties, meals priced at $10 is now value about $37 in 2023. Meals value inflation has elevated, and this has an affect within the meals that persons are capable of afford every week.
Well being care – Modifications in healthcare prices and entry can have an effect on people’ means to handle their well being. Excessive healthcare bills and restricted entry to reasonably priced healthcare providers can hinder weight problems prevention and administration efforts.
What occurs after we eat numerous ultra-processed meals?
Van Tulleken isn’t incorrect when he writes {that a} food regimen stuffed with UPF is related to poor well being outcomes.
Alongside an analogous line, current analysis confirms that we are inclined to devour extra energy and achieve extra weight after we devour a food regimen that’s predominantly UPF, even when energy and macronutrients are matched. A much less rigorous trial than the one above however one by Fernanda Rauber, whose work Van Tulleken used for the e-book, suggests the identical findings.
There’s fairly a little bit of analysis that appears to substantiate {that a} food regimen that’s excessive in ultra-processed meals is linked to most cancers and weight problems.
Van Tulleken makes an enormous deal about emulsifiers and the way they negatively affect our intestine micro organism, however there’s actually no persuasive analysis to again that declare up. It’s simply one other principle, courtesy of the writer.
Extremely Processed Folks makes numerous claims which might be supported solely by preliminary analysis, though I really feel as if that is acknowledged as a caveat for readers. However in doing this, Van Tulleken appears to oversimplify advanced points, which I feel is unfair.
For instance, for his e-book ‘analysis,’ Van Tulleken put himself on a food regimen comprised of 80% ultra-processed meals. By week three, he turned constipated, exhausted, offended, and depressing. That is when he began to dive deeper into the consequences UPF has on the physique.
He then obtained mind scans carried out. The physician who did the scans apparently observed that ‘the wiring of his mind hadn’t modified, however the data flowing by means of the wires had.’ She additionally instructed him that these modifications don’t happen except one thing important has occurred within the physiology of the mind.
Frustratingly, Van Tulleken didn’t hassle to go additional to elucidate what the scans really picked up on, and what the medical relevance could be for folks consuming this a lot UPF.
Except for the mind scans, nothing he skilled actually shocks me. He went from consuming minimal ultra-processed meals to consuming nearly all UPF, which might clearly affect his well being and the best way he felt – even in a matter of weeks.
Extremely-processed meals are sometimes low in important vitamins like fibre, nutritional vitamins and minerals. It’s typically extremely processed. Relying on which meals Van Tulleken ate, it’s utterly unsurprising that he would have modifications in his bodily capabilities and his temper.
He says that extremely processed meals are usually comfortable and simply digested. Based on analysis, this will result in overconsumption as a result of the meals is simple to eat shortly, and is easer for the physique to soak up.
Van Tulleken delves into components and the sensory points of ultra-processed meals, particularly specializing in the usage of scent to set off the mind’s dopamine reward system when opening UPF packaging.
The thought is that the scent makes ultra-processed meals appear extra interesting, which might result in cravings as soon as the package deal is opened. He believes that this phenomenon has the potential to disrupt the physique’s means to type correct associations between vitamins and meals.
It’s necessary to notice that Van Tulleken doesn’t explicitly present proof to help this declare.
Within the USA, firms are allowed to self-determine substances this tends to occur in smaller firms. He goes into saying that issues just like the corn oil in our kitchens might have been produced utilizing a expertise that leaves it stuffed with unlicensed components and antibiotics.
The writer’s goal appears to be to highlight the shortage of transparency and potential dangers related to the FDA and its regulation of the meals system. That is undoubtedly an necessary dialog that we ought to be having.
FYI: Greens powders and protein powders are ultra-processed meals, too.
Van Tulleken reaches far when he talks about how people could develop a robust choice for ultra-processed meals over conventional, domestically sourced, extra nutritious meals. This shift in choice can result in a major departure from conventional diets, which can have as soon as supplied a extra balanced and healthful supply of diet.
I’m not an anthropologist, however I’d argue that if folks aren’t consuming their conventional meals, there’s different causes moreover a McDonald’s transferring in down the block.
Extremely Processed Folks assessment, briefly:
The Extremely Processed Folks e-book is a combined bag of issues we already know (a food regimen stuffed with UPF isn’t best), issues that the writer is speculating about, and issues he’s asserting however not backing up with credible proof.
Van Tulleken will get fairly a bit proper in Extremely-Processed Folks. I favored that he acknowledged that social determinants of well being have an effect on our meals selections, and that he’s in opposition to ‘good’ and ‘dangerous’ labels for meals.
He asks questions concerning the FDA’s regulatory processes for meals. Whereas I feel this is a crucial matter, the verbiage Van Tulleken makes use of in that part and others appears to deliberately sensationalize the subject material. At all times do not forget that the dose makes the poison.
There’s numerous reaching, anecdotes, and unsubstantiated claims within the e-book.
That being stated, he’s completely right that ultra-processed meals are simpler to eat and soak up, and that their palatability is simple.
No person right here is arguing that ultra-processed meals ought to comprise the vast majority of our food regimen. Precisely the alternative, really. However UPF can and do play a job in a nutritious diet with their accessibility, comfort, style, and sure – vitamins.
Addressing how a lot extremely processed meals we eat, together with disparities in diet and well being, requires fixing of society’s underlying inequalities to make sure that everybody, no matter their circumstances, has an equitable alternative to make nutritious selections for themselves and their households.
