Extremely Processed Individuals Evaluate – Abby Langer Diet

Writer 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 guide Extremely Processed Individuals, he focuses on the query of weight problems with its relation to Extremely Processed Meals (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 individuals data to ‘arm your self with the easy and not-so-simple details that may provide help to make the alternatives which might be best for you.’

This Extremely Processed Individuals overview 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 totally attainable 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 individuals earlier than they even open it.

Based on Van Tulleken, over the previous 150 years, we’ve got begun to eat 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 eat increasingly UPF that in flip, will be dangerous to the physique.

Whereas this can be appropriate, it’s necessary to understand the nuance behind meals selections and diet 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 whole diets mustn’t encompass 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 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 in the end, 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 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, comparable to earnings, schooling, and dwelling situations, can exert a big 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 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 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 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 really want 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 reduce weight. The validity of a ‘meals dependancy’ analysis is controversial:  Some individuals do have signs that will mimic dependancy however this doesn’t occur with everybody. It’s unknown if these signs are resulting from 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 lots of Van Tulleken’s theories in Extremely Processed Individuals, I discover this one to be an oversimplification of a fancy concern: how can we are saying that weight problems is instantly resulting from UPF intakes?

Listed below are another variations between now and the 80’s:

Residence Economics isn’t a lot of a factor in colleges anymore

Right this moment, we’ve got a tradition the place being busy is praised, resulting in elevated stress and nervousness

We’re extra sedentary, particularly with display time and the provision of on-line…all the pieces

There’s a larger alternative in grocery shops, which may result in elevated consumption

Decreased group helps

Elevated value of dwelling – The rising value of dwelling, together with bills associated to housing, healthcare, and schooling, can influence individuals’s capability to prioritize well being and diet.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 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 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 lots of ultra-processed meals?

Van Tulleken isn’t unsuitable 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 eat extra energy and acquire extra weight after we eat 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 substantiate {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 writer.

Extremely Processed Individuals makes lots of claims which might 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 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 carried out. 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 instructed him that these adjustments 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 can be for individuals 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 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 features and his temper. 

He says that extremely processed meals are typically tender and simply digested. Based on analysis, this may result in overconsumption as a result of the meals is straightforward to eat shortly, 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 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 capability to type correct associations between vitamins and meals. 

It’s necessary 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 writer’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 necessary 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 big 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 in addition to a McDonald’s transferring in down the block.

Extremely Processed Individuals overview, in brief:

The Extremely Processed Individuals guide is a combined bag of issues we already know (a weight loss plan filled with UPF isn’t excellent), 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 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 in opposition to ‘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 crucial matter, the verbiage Van Tulleken makes use of in that part and others appears to deliberately sensationalize the subject material. At all times 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 appropriate that ultra-processed meals are simpler to eat and take up, and that their palatability is simple. 

No one right here is arguing that ultra-processed meals ought to comprise nearly all of our weight loss plan. Precisely the alternative, 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 selections for themselves and their households.
