Creator Chris Van Tulleken is an infectious illnesses physician on the College School Hospital in London for Tropical Illnesses 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 Individuals, he focuses on the query of weight problems with its relation to Extremely Processed Meals (UPF). He gives a mixture of evaluation and commentary to point out how UPFs have an effect on the human physique, and the way they’re marketed.
Van Tulleken’s objective is to provide individuals data to ‘arm your self with the straightforward and not-so-simple info that may allow you to make the alternatives which can be best for you.’
This Extremely Processed Individuals overview 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 imagine that it’s solely attainable 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 typically 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 individuals earlier than they even open it.
In line with Van Tulleken, over the previous 150 years, now we have begun to eat 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 typical food plan within the UK and USA.
Van Tulleken outlines that as time goes on, people are starting to eat an increasing number of UPF that in flip, might be dangerous to the physique.
Whereas this can be appropriate, it’s necessary to understand the nuance behind meals selections and diet basically: sure, UPF might enhance danger for illness in the event that they’re all persons are consuming.
I’m keen to enterprise that almost all people on this planet perceive that their total 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 making an attempt to outlive on a restricted meals finances.
There are outliers, after all, however social determinants of well being are intimately linked to meals selections and finally, 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 assets like time, funds, and schooling.
No, we don’t all have the identical 24 hours in a day. Right here’s why.
Moreover, socioeconomic components, resembling revenue, schooling, and residing circumstances, can exert a major affect, usually constraining individuals to depend on extra handy and processed meals choices.
All of this stuff can influence the quantity of ultra-processed meals somebody eats, and Van Tulleken acknowledges this within the e-book.
NOVA classification
Van Tulleken talks in regards to the NOVA classification of UPF. NOVA classification of meals is a standardized methodology 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 manner 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 knowledge. 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 put up about ultra-processed meals right here.
Van Tulleken hypothesizes that UPF are engineered to be addictive, which he says complicates issues when somebody is making an attempt to chop these meals to shed extra pounds. The validity of a ‘meals dependancy’ analysis is controversial: Some individuals do have signs which will mimic dependancy however this doesn’t occur with everybody. It’s unknown if these signs are because of 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 a number of Van Tulleken’s theories in Extremely Processed Individuals, I discover this one to be an oversimplification of a posh challenge: how can we are saying that weight problems is instantly because of UPF intakes?
Listed below are another variations between now and the 80’s:
House Economics isn’t a lot of a factor in colleges anymore
Right now, now we have a tradition the place being busy is praised, resulting in elevated stress and anxiousness
We’re extra sedentary, particularly with display screen time and the provision of on-line…the whole lot
There’s a better selection in grocery shops, which may result in elevated consumption
Decreased group helps
Elevated value of residing – The rising value of residing, together with bills associated to housing, healthcare, and schooling, can influence individuals’s potential to prioritize well being and diet.When people and households face monetary constraints, they could 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 worth inflation has elevated, and this has an influence within the meals that persons are in a position to afford every week.
Well being care – Modifications in healthcare prices and entry can have an effect on people’ potential to handle their well being. Excessive healthcare bills and restricted entry to inexpensive healthcare providers can hinder weight problems prevention and administration efforts.
What occurs once we eat a number of ultra-processed meals?
Van Tulleken isn’t fallacious when he writes {that a} food plan stuffed with UPF is related to poor well being outcomes.
Alongside an identical line, latest analysis confirms that we are inclined to eat extra energy and achieve extra weight once we eat a food plan 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 plan 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 influence 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 creator.
Extremely Processed Individuals makes a number of claims which can 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 complicated points, which I feel is unfair.
For instance, for his e-book ‘analysis,’ Van Tulleken put himself on a food plan comprised of 80% ultra-processed meals. By week three, he grew to become constipated, exhausted, offended, and depressing. That is when he began to dive deeper into the results UPF has on the physique.
He then obtained mind scans finished. The physician who did the scans apparently seen that ‘the wiring of his mind hadn’t modified, however the data flowing via the wires had.’ She additionally informed him that these adjustments don’t happen except one thing vital has occurred within the physiology of the mind.
Frustratingly, Van Tulleken didn’t hassle to go additional to elucidate what the scans truly picked up on, and what the scientific relevance could be for individuals 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 influence 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 usually extremely processed. Relying on which meals Van Tulleken ate, it’s fully unsurprising that he would have adjustments in his bodily capabilities and his temper.
He says that extremely processed meals are usually smooth and simply digested. In line with analysis, this may 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 facets of ultra-processed meals, particularly specializing in using scent to set off the mind’s dopamine reward system when opening UPF packaging.
The concept is that the scent makes ultra-processed meals appear extra interesting, which may result in cravings as soon as the package deal is opened. He believes that this phenomenon has the potential to disrupt the physique’s potential to type correct associations between vitamins and meals.
It’s necessary to notice that Van Tulleken doesn’t explicitly present proof to assist this declare.
Within the USA, corporations are allowed to self-determine substances this tends to occur in smaller corporations. He goes into saying that issues just like the corn oil in our kitchens may have been produced utilizing a know-how that leaves it stuffed with unlicensed components and antibiotics.
The creator’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 positively an necessary dialog that we must be having.
FYI: Greens powders and protein powders are ultra-processed meals, too.
Van Tulleken reaches far when he talks about how people might develop a powerful desire for ultra-processed meals over conventional, regionally sourced, extra nutritious meals. This shift in desire 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 individuals aren’t consuming their conventional meals, there’s different causes moreover a McDonald’s shifting in down the block.
Extremely Processed Individuals overview, briefly:
The Extremely Processed Individuals e-book is a combined bag of issues we already know (a food plan stuffed with UPF isn’t best), issues that the creator 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 Individuals. I preferred that he acknowledged that social determinants of well being have an effect on our meals selections, and that he’s towards ‘good’ and ‘unhealthy’ labels for meals.
He asks questions in regards to 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. All the time do not forget that the dose makes the poison.
There’s a number of reaching, anecdotes, and unsubstantiated claims within the e-book.
That being mentioned, he’s completely appropriate that ultra-processed meals are simpler to eat and take in, and that their palatability is plain.
No person right here is arguing that ultra-processed meals ought to comprise the vast majority of our food plan. Precisely the alternative, truly. 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.
