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 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 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 individuals earlier than they even open it.
In line with Van Tulleken, over the previous 150 years, now we have begun to devour substances constructed from molecules utilizing a number of sorts of processing. A lot 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 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 vital to comprehend the nuance behind meals decisions and diet on the whole: sure, UPF could improve threat for illness in the event that they’re all individuals are consuming.
I’m prepared 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 individual has a alternative of what to eat – in lots of circumstances, 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 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, equivalent to earnings, schooling, and residing situations, can exert a big affect, typically constraining individuals to depend on extra handy and processed meals choices.
All of these items 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 elements
Group 3: Processed meals
Group 4: Extremely-processed meals
NOVA is a reasonably fundamental means 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 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 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 for the reason that 1980’s, the prevalence of weight problems has skyrocketed, which he believes is due to our UPF behavior. Like loads of Van Tulleken’s theories in Extremely Processed Folks, I discover this one to be an oversimplification of a posh situation: how can we are saying that weight problems is straight because 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
Right now, now we have a tradition the place being busy is praised, resulting in elevated stress and nervousness
We’re extra sedentary, particularly with display screen time and the provision of on-line…the whole lot
There’s a better alternative in grocery shops, which might result in elevated consumption
Decreased group helps
Elevated price of residing – The rising price of residing, together with bills associated to housing, healthcare, and schooling, can influence individuals’s capacity 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 for the reason that Nineteen Eighties, meals priced at $10 is now price about $37 in 2023. Meals value inflation has elevated, and this has an influence within the meals that individuals are in a position to afford every week.
Well being care – Adjustments in healthcare prices and entry can have an effect on people’ capacity 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 loads of ultra-processed meals?
Van Tulleken isn’t improper 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 likely to devour extra energy and achieve extra weight after 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 e book, 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 influence our intestine micro organism, however there’s actually no persuasive analysis to again that declare up. It’s simply one other idea, courtesy of the creator.
Extremely Processed Folks makes loads of claims which might be supported solely by preliminary analysis, though I really feel as if that is said 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 loss 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 performed. The physician who did the scans apparently seen that ‘the wiring of his mind hadn’t modified, however the data flowing by the wires had.’ She additionally instructed 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 scientific 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 nearly 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 typically extremely processed. Relying on which meals Van Tulleken ate, it’s utterly unsurprising that he would have modifications in his bodily features and his temper.
He says that extremely processed meals are typically tender and simply digested. In line with analysis, this could 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 capacity to kind correct associations between vitamins and meals.
It’s vital 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 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 positively an vital 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 could develop a powerful choice for ultra-processed meals over conventional, regionally sourced, extra nutritious meals. This shift in choice can result in a big departure from conventional diets, which can have as soon as offered 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 in addition to a McDonald’s shifting in down the block.
Extremely Processed Folks evaluation, in brief:
The Extremely Processed Folks e book is a blended bag of issues we already know (a weight loss plan filled 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 Folks. I favored that he acknowledged that social determinants of well being have an effect on our meals decisions, and that he’s in opposition to ‘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 crucial 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 loads of reaching, anecdotes, and unsubstantiated claims within the e book.
That being mentioned, he’s completely right that ultra-processed meals are simpler to eat and take up, and that their palatability is plain.
No person right here is arguing that ultra-processed meals ought to comprise nearly all 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 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 decisions for themselves and their households.
