In his guide Extremely Processed Folks, he focuses on the query of weight problems with its relation to Extremely Processed Meals (UPF). He offers 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 straightforward and not-so-simple info that can allow you to make the alternatives which can be best for you.’
This Extremely Processed Folks evaluation addresses the bigger factors within the guide.

As a dietitian, I believe 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 fully potential to be wholesome and to eat some UPF.
Beginning out, the guide’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 guide, it’s a bit wealthy that the guide’s cowl would meals disgrace folks earlier than they even open it.
In line with Van Tulleken, over the previous 150 years, we have now begun to devour substances constructed from molecules utilizing a number of sorts of processing. A lot of our energy are coming from substances 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 weight loss plan within the UK and USA.
Van Tulleken outlines that as time goes on, people are starting to devour increasingly UPF that in flip, will be dangerous to the physique.
Whereas this can be right, it’s essential to comprehend the nuance behind meals selections and vitamin generally: sure, UPF might enhance threat for illness in the event that they’re all individuals are consuming.
I’m keen to enterprise that the majority people on this planet perceive that their total diets mustn’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 finances.
There are outliers, in fact, 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 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 components, reminiscent of revenue, training, and residing circumstances, can exert a major affect, usually constraining folks to depend on extra handy and processed meals choices.
All of this stuff can impression the quantity of ultra-processed meals somebody eats, and Van Tulleken acknowledges this within the guide.
NOVA classification
Van Tulleken talks in regards to the NOVA classification of UPF. NOVA classification of meals is a standardized technique for categorization of meals, largely for scientific functions.
NOVA classes are:
Group 1: Unprocessed and minimally processed meals
Group 2: Processed culinary substances
Group 3: Processed meals
Group 4: Extremely-processed meals
NOVA is a reasonably fundamental means of placing meals into free 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 actually need 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 attempting to chop these meals to shed pounds. The validity of a ‘meals habit’ prognosis is controversial: Some folks do have signs that will mimic habit however this doesn’t occur with everybody. It’s unknown if these signs are as a consequence of an precise bodily habit.
He talks about how for the reason that 1980’s, the prevalence of weight problems has skyrocketed, which he believes is due to our UPF behavior. Like lots of Van Tulleken’s theories in Extremely Processed Folks, I discover this one to be an oversimplification of a posh challenge: how can we are saying that weight problems is straight as a consequence of UPF intakes?
Listed below are another variations between now and the 80’s:
Dwelling Economics isn’t a lot of a factor in faculties anymore
At present, we have now 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 thing
There’s a better selection in grocery shops, which might result in elevated consumption
Decreased group helps
Elevated value of residing – The rising value of residing, together with bills associated to housing, healthcare, and training, can impression folks’s potential to prioritize well being and vitamin.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 for the reason that Nineteen Eighties, meals priced at $10 is now value about $37 in 2023. Meals value inflation has elevated, and this has an impression within the meals that individuals are capable of 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 reasonably priced healthcare providers can hinder weight problems prevention and administration efforts.
What occurs once we eat lots of ultra-processed meals?
Van Tulleken isn’t fallacious when he writes {that a} weight loss plan filled with UPF is related to poor well being outcomes.
Alongside the same line, latest analysis confirms that we are inclined to devour extra energy and achieve extra weight once we devour a weight loss 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 guide, suggests the identical findings.
There’s fairly a little bit of analysis that appears to verify {that a} weight loss 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 impression our intestine micro organism, however there’s actually no persuasive analysis to again that declare up. It’s simply one other concept, courtesy of the creator.
Extremely Processed Folks makes lots 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 advanced points, which I believe is unfair.
For instance, for his guide ‘analysis,’ Van Tulleken put himself on a weight loss plan comprised of 80% ultra-processed meals. By week three, he grew to become constipated, exhausted, indignant, and depressing. That is when he began to dive deeper into the results UPF has on the physique.
He then bought mind scans finished. The physician who did the scans apparently observed that ‘the wiring of his mind hadn’t modified, however the data flowing by way of the wires had.’ She additionally informed him that these modifications 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 clarify what the scans really picked up on, and what the medical relevance can be for folks consuming this a lot UPF.
Apart from the mind scans, nothing he skilled actually shocks me. He went from consuming minimal ultra-processed meals to consuming virtually all UPF, which might clearly impression 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 utterly unsurprising that he would have modifications in his bodily capabilities and his temper.
He says that extremely processed meals are typically gentle and simply digested. In line with 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 features 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 concept is that the scent makes ultra-processed meals appear extra interesting, which might result in cravings as soon as the bundle is opened. He believes that this phenomenon has the potential to disrupt the physique’s potential to kind correct associations between vitamins and meals.
It’s essential 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 may have been produced utilizing a expertise that leaves it filled with unlicensed components and antibiotics.
The creator’s purpose 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 essential dialog that we needs to 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 choice for ultra-processed meals over conventional, regionally sourced, extra nutritious meals. This shift in choice can result in a major departure from conventional diets, which can have as soon as offered a extra balanced and healthful supply of vitamin.
I’m not an anthropologist, however I’d argue that if folks aren’t consuming their conventional meals, there’s different causes apart from a McDonald’s shifting in down the block.
Extremely Processed Folks evaluation, briefly:
The Extremely Processed Folks guide is a combined bag of issues we already know (a weight loss plan filled with UPF isn’t preferrred), 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 Folks. 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 ‘dangerous’ labels for meals.
He asks questions in regards to the FDA’s regulatory processes for meals. Whereas I believe this is a vital matter, the verbiage Van Tulleken makes use of in that part and others appears to deliberately sensationalize the subject material. All the time keep in mind that the dose makes the poison.
There’s lots of reaching, anecdotes, and unsubstantiated claims within the guide.
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 one right here is arguing that ultra-processed meals ought to comprise the vast majority of our weight loss plan. Precisely the other, 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 vitamin 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.
