In his e book 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 purpose is to present individuals info to ‘arm your self with the straightforward and not-so-simple info that may enable you make the alternatives which are best for you.’
This Extremely Processed Folks overview addresses the bigger factors within the e book.

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 imagine that it’s solely 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 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 accordance with Van Tulleken, over the previous 150 years, we have now begun to eat substances constructed from molecules utilizing a number of sorts of processing. Lots of our energy are coming from components 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-reduction plan within the UK and USA.
Van Tulleken outlines that as time goes on, people are starting to eat increasingly more UPF that in flip, may be dangerous to the physique.
Whereas this can be right, it’s essential to understand the nuance behind meals decisions and vitamin usually: sure, UPF could improve threat for illness in the event that they’re all persons are consuming.
I’m keen to enterprise that the majority people on this planet perceive that their total diets shouldn’t encompass meals like chips and soda; and, when that is the case, it’s not as a result of the particular person has a alternative of what to eat – in lots of instances, they’re making an attempt to outlive on a restricted meals price range.
There are outliers, in fact, however social determinants of well being are intimately linked to meals decisions and in the end, to an individual’s well being standing and outcomes.

A person’s capability to make knowledgeable and wholesome meals decisions is closely influenced by a fancy 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 elements, corresponding to revenue, schooling, and dwelling 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 technique for categorization of meals, principally for scientific functions.
NOVA classes are:
Group 1: Unprocessed and minimally processed meals
Group 2: Processed culinary components
Group 3: Processed meals
Group 4: Extremely-processed meals
NOVA is a reasonably primary method of placing meals into unfastened classes, however its usefulness in on a regular basis life is questionable. Its accuracy can be considerably controversial, because it’s constructed on subjective information. It’s pretty apparent which meals are unprocessed and minimally processed, and 1000’s 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 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 making an attempt to chop these meals to drop pounds. The validity of a ‘meals habit’ analysis is controversial: Some individuals do have signs that will mimic habit however this doesn’t occur with everybody. It’s unknown if these signs are as a result of an precise bodily habit.
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 quite a lot of Van Tulleken’s theories in Extremely Processed Folks, I discover this one to be an oversimplification of a fancy subject: how can we are saying that weight problems is straight as a result of UPF intakes?
Listed here are another variations between now and the 80’s:
Residence Economics isn’t a lot of a factor in colleges anymore
Immediately, we have now a tradition the place being busy is praised, resulting in elevated stress and anxiousness
We’re extra sedentary, particularly with display time and the supply of on-line…every part
There’s a larger alternative 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 schooling, can influence individuals’s capability to prioritize well being and vitamin.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 worth inflation has elevated, and this has an influence within the meals that persons are capable of afford every week.
Well being care – Adjustments in healthcare prices and entry can have an effect on people’ capability to handle their well being. Excessive healthcare bills and restricted entry to inexpensive healthcare companies can hinder weight problems prevention and administration efforts.
What occurs after we eat quite a lot of ultra-processed meals?
Van Tulleken isn’t fallacious when he writes {that a} weight-reduction plan filled with UPF is related to poor well being outcomes.
Alongside an identical line, current analysis confirms that we are likely to eat extra energy and achieve extra weight after we eat a weight-reduction 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} weight-reduction 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 concept, courtesy of the creator.
Extremely Processed Folks makes quite a lot of claims which are 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 e book ‘analysis,’ Van Tulleken put himself on a weight-reduction plan comprised of 80% ultra-processed meals. By week three, he turned constipated, exhausted, indignant, and depressing. That is when he began to dive deeper into the consequences UPF has on the physique.
He then received mind scans executed. The physician who did the scans apparently observed that ‘the wiring of his mind hadn’t modified, however the info flowing by means of the wires had.’ She additionally informed him that these modifications don’t happen until one thing important has occurred within the physiology of the mind.
Frustratingly, Van Tulleken didn’t trouble to go additional to elucidate what the scans really picked up on, and what the medical relevance could be for individuals consuming this a lot UPF.
Other than 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 influence his well being and the way in which 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 tender and simply digested. In accordance with analysis, this will result in overconsumption as a result of the meals is straightforward to eat rapidly, and is easer for the physique to soak up.
Van Tulleken delves into components and the sensory elements 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 bundle is opened. He believes that this phenomenon has the potential to disrupt the physique’s capability 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 know-how that leaves it filled with unlicensed components and antibiotics.
The creator’s purpose appears to be to highlight the dearth 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 could develop a robust 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 supplied a extra balanced and healthful supply of vitamin.
I’m not an anthropologist, however I’d argue that if individuals aren’t consuming their conventional meals, there’s different causes apart from a McDonald’s transferring in down the block.
Extremely Processed Folks overview, in brief:
The Extremely Processed Folks e book is a blended bag of issues we already know (a weight-reduction plan filled with UPF isn’t excellent), 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 decisions, 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 believe this is a vital subject, 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 quite a lot of 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 take 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 weight-reduction plan. Precisely the alternative, really. However UPF can and do play a task 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 decisions for themselves and their households.
