In his e book Ultra Processed People, he focuses on the query of weight problems with its relation to Ultra Processed Food (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 purpose is to offer folks info to ‘arm yourself with the simple and not-so-simple facts that will help you make the choices that are right for you.’

As a dietitian, I believe ultra-processed meals does have a rightful place in our world. Should our diets be made up solely from it? Not ideally. But, I do imagine that it’s fully doable to be wholesome and to eat some UPF.
Starting out, the e book’s cowl calls UPF ‘food that isn’t meals.’ Not solely is ultra-processed meals precise meals, it’s generally the one meals people can afford.
While 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.
According to Van Tulleken, over the previous 150 years, we now have begun to eat substances constructed from molecules utilizing a number of sorts of processing. Many 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 loss program 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.
While this can be right, it’s essential to appreciate the nuance behind meals decisions and vitamin on the whole: sure, UPF might improve danger 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 individual has a selection of what to eat – in lots of circumstances, they’re attempting 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.

An particular 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 sources like time, funds, and training.
No, we don’t all have the identical 24 hours in a day. Here’s why.
Additionally, socioeconomic components, reminiscent of earnings, training, and dwelling situations, 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 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, largely for scientific functions.
NOVA classes are:
Group 1: Unprocessed and minimally processed meals
Group 2: Processed culinary components
Group 3: Processed meals
Group 4: Ultra-processed meals
NOVA is a reasonably fundamental manner 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 knowledge. 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 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 drop extra pounds. The validity of a ‘food addiction’ 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 attributable to 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 plenty of Van Tulleken’s theories in Ultra Processed People, I discover this one to be an oversimplification of a fancy situation: how can we are saying that weight problems is instantly attributable to UPF intakes?
Here are another variations between now and the 80’s:
Home Economics isn’t a lot of a factor in colleges anymore
Today, we now 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…every little thing
There’s a higher selection in grocery shops, which might result in elevated consumption
Decreased group helps
Increased price of dwelling – The rising price of dwelling, 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 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 price about $37 in 2023. Food value inflation has elevated, and this has an impression within the meals that individuals are capable of afford every week.
Health care – Changes in healthcare prices and entry can have an effect on people’ potential to handle their well being. High healthcare bills and restricted entry to reasonably priced healthcare companies can hinder weight problems prevention and administration efforts.
What occurs after we eat plenty of ultra-processed meals?
Van Tulleken isn’t unsuitable when he writes {that a} weight loss program stuffed with UPF is related to poor well being outcomes.
Along the same line, current analysis confirms that we are inclined to eat extra energy and acquire extra weight after we eat a weight loss program 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 loss program 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 principle, courtesy of the writer.
Ultra Processed People makes plenty of claims which can be supported solely by preliminary analysis, though I really feel as if that is said as a caveat for readers. But in doing this, Van Tulleken appears to oversimplify complicated points, which I believe is unfair.
For instance, for his e book ‘research,’ Van Tulleken put himself on a weight loss program comprised of 80% ultra-processed meals. By week three, he turned constipated, exhausted, offended, and depressing. This is when he began to dive deeper into the results 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 brain hadn’t modified, however the info flowing via the wires had.’ She additionally instructed 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 really picked up on, and what the medical relevance could be for folks consuming this a lot UPF.
Aside 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.
Ultra-processed meals are sometimes low in important vitamins like fibre, nutritional vitamins and minerals. It’s usually extremely processed. Depending on which meals Van Tulleken ate, it’s utterly unsurprising that he would have adjustments in his bodily capabilities and his temper.
He says that extremely processed meals are typically gentle and simply digested. According to analysis, this may result in overconsumption as a result of the meals is simple to eat rapidly, 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 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 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.
In 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 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 dearth of transparency and potential dangers related to the FDA and its regulation of the meals system. This is certainly an essential 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 might develop a powerful 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 vitamin.
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.
Ultra Processed People evaluate, in brief:
The Ultra Processed People e book is a blended bag of issues we already know (a weight loss program stuffed with UPF isn’t splendid), 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 Ultra-Processed People. 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 ‘bad’ labels for meals.
He asks questions in regards to the FDA’s regulatory processes for meals. While 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. Always keep in mind that the dose makes the poison.
There’s plenty 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 soak up, and that their palatability is simple.
Nobody right here is arguing that ultra-processed meals ought to comprise nearly all of our weight loss program. Exactly the alternative, really. But 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.
