Ultra-processed foods (UPFs) have more in common with cigarettes than with fruit or vegetables, and require far tighter regulation, according to a new report.

UPFs and cigarettes are engineered to encourage addiction and consumption, researchers from three US universities said, pointing to the parallels in widespread health harms that link both.

UPFs, which are widely available worldwide, are food products that have been industrially manufactured, often using emulsifiers or artificial colouring and flavours. The category includes soft drinks and packaged snacks such as crisps and biscuits.

There are similarities in the production processes of UPFs and cigarettes, and in manufacturers’ efforts to optimise the “doses” of products and how quickly they act on reward pathways in the body, according to the paper from researchers at Harvard, the University of Michigan and Duke University.

One of the authors, Prof Ashley Gearhardt of the University of Michigan, a clinical psychologist specialising in addiction, said her patients made the same links: “They would say, ‘I feel addicted to this stuff, I crave it – I used to smoke cigarettes [and] now I have the same habit but it’s with soda and doughnuts. I know it’s killing me; I want to quit, but I can’t.’”

Me, drinking yet another Dr. Pepper Zero: "Uh oh."

There's still the huge problem that nobody knows what an UPF actually is. Name a definition, somebody's traditional home-cooked cuisine does it. Unless home-cooked is your definition, in which case you ascribe too much navigational prowess to food - it has no idea where it's being cooked.

Yeah a food scientist remarked that technically you could call tofu an "ultra processed food"

[–] turboSnail@piefed.europe.pub 10 points 22 hours ago

Exactly. It's one of those "I know it when I see it" type of things rather than a solid definition. Like Froot Loops definitely are UPF, but what about a salad in a plastic box? Sure, it's been through a factory where it got chopped, mixed and packaged. That's industrial scale food processing too, right?

How the fuck do you expect to get kids to eat salad when the salad dressing is locked behind a counter with the cigarettes?

The problem is that "ultra-processed foods" is too broad to be meaningful. Also the fact that, you know, some amount of personal choice is essential to a free society.

[–] albus@lemmy.world 27 points 1 day ago (2 children)

When I was an italian kid, I have never had problems eating salads with no ultra-processed dressing.

[–] moakley@lemmy.world 10 points 1 day ago (1 children)

I'm sure that's because of choices that your parents made and nothing to do with living in an area with high population density and easy access to fresh food.

[–] ranzispa@mander.xyz 3 points 9 hours ago

I don't understand. I'm pretty sure raising a child depends on the choices of the parents. What do you mean, that in areas with higher population density it is easier to get fresh food? And that thus the parent's choices are not influential or only possible because of the environment? In my experience fresh food is more accessible in low population density areas, thus I don't really follow.

it is not ultra-processed, it is just processed.

The best example I can think of to represent what the article is taking about is Doritos. I like to think of myself as someone with a decent amount of self-control. But if I ever see a bag of Doritos I can crush a whole value pack in two sittings. That stuff is engineered to be as addictive as possible and it shows. The only reason why I'm not a walking blimp is that I dont buy any because I know what happens when that stuff is in my house.

If only they engineered something that was both addictive and healthy for a change. But I guess there isn't much incentive to sacrifice maximum addictiveness for health.

This confirms your decent amount of self-control.

The comedian Louis CK once said: "I don't stop eating when I feel full. I stop eating when I start hating myself."

It could just be a lower threshold for self-hatred.

[–] Fafa@lemmy.world 24 points 1 day ago (3 children)

There is a certain ratio of carbohydrates to fat that stops us from being able to control how much we eat. (50:35 carbohydrates to fat) plus salt, flavour enhancers and whatever sells the product...

I once killed an entire party size bag of Doritos by myself.

To be fair I was really baked at the time.

True, my addiction to Protein shakes will give me lung cancer soon.

Can we use a different label like "addictive foods"? UPF is so incredibly broad and undefined I'd argue bread is an UPF.

[–] moakley@lemmy.world 21 points 1 day ago (1 children)

Bread literally is a UPF most of the time. Not necessarily the fresh baked bread that you get from a bakery, but the manufactured bread that's slightly less healthy but is much cheaper and more accessible to people in remote or impoverished places.

A lot of ultra-processed foods exist because they're solving specific problems, and you can't just ban them without providing a better solution to those problems.

Danny and the gang are cutting class to meet behind the bleachers; says he's got a family pack of Twinkies and a 3-liter bottle of knock-off Mountain Dew. You in?
