Couldn't agree more. I see this a lot here in Norway too. So much talk of "ultra-processed" food and its dangers, and recommendations to avoid it but the category is so wide as to include even things like baked beans, because they may have some salt, sugar and modified starch added; or peanut butter because it may have some sugar added to help it stay emulsified and some saturated fat added to make it less runny.

Does that processing suddenly turn the beans from one of the healthiest foods we know of to an unhealthy one? Probably not. Does it make them easier to use in cooking vs dried beans, leading more people to eat beans? Probably yes.

Same thing for the peanut butter. As part of my breakfast, I often have a slice or two of brown, whole grain bread with peanutbutter(the non-disgusting kind with additives mentioned above, about 89% peanuts) and banana. That's a meal rich in protein, various kinds of fiber, polyunsaturated fats, slow carbs, various vitamins and minerals. The fact that the PB has a little sugar and sat fat in it doesn't really matter very much. I've tried PB That's 99% peanuts and frankly it's disgusting. It separates, it's runny and it has an off taste too. If that was the only PB on the market I wouldn't even use it.

The problem is 1. That government recommendations and public discourse place far, far too much emphasis on population studies based on overly vague categories like this and 2. That there's an almost singular focus on things people should avoid rather than things people need more of, especially fibre and protein. Fibre is crucially important, and maybe this is a hot take, but I think lack of fibre is maybe the most important factor when it comes to public health and food.

Fibre increases satiety and bulk, leading you to eat less calories, lowers glycemic index avoiding insulin resistance and diabetes, improves intestinal function(via interaction with gut biome) and therefore micronutrient uptake, and it(specifically beta-glucans found in oats and other grains) even lowers LDL cholesterol. Not to mention it prevents hemorrhoids, which might not affect longevity, but it's certainly nice. And indeed, no surprise, a lot of "ultra-processed" food happens to be devoid of fibre.

I think "fibre-depleted" and "protein-depleted" would be more useful categories to use than the much more vague "ultra-processed".

Modified starch seems like a prime candidate for an ultra-processed ingredient. I don't know which one is used in baked beans, but there's a whole list of enzymes, acids and alkalis used: https://en.wikipedia.org/wiki/Modified_starch

I didn't realize we could buy 89% peanut butter in Europe. At my nearest supermarket in Copenhagen I have the choice of 99.5% (Machandel), 99.6% (Urtekram) or 99.3% (Salling). The other 11% of yours is probably palm oil, sugar and salt, so less questionable than the modified starch but it's still additives to increase shelf life and make the boring, natural peanut more appealing.

The cheapest peanut butter here (UK) often contains xylitol. Not so much of an issue for people, but is toxic to dogs.

It's by far the most sold one. I just checked, and it's not palm oil(which I would be opposed to for environmental reasons), but sunflower oil(probably high-stearic, though it doesn't say), diglycerides and monoglycerides, salt and glucose. probably most of the additive is the sunflower oil.

Anyway, it doesn't really matter, that's my point. the 89% peanuts gives me lots of protein, fibre and healthy fats, which is making it easier for me to diet and lose weight, thereby improving my health. That almost certainly outweighs any potential risks from the 11%. The 11% honestly helps in that it makes the whole thing palatable. I can't overstate how much I hate pure peanut butter; just thinking about it makes me gag.

I mean, adding stuff to food to make it more appealing or longer-lasting is what humans do. It's what we've always done. Just concluding that it's bad and shouldn't be done is silly. I'm much more interested in specifics.

You can even make a health-positive argument for preservatives. Preservatives prolong shelf life -> means I can keep more diverse food around with less time expenditure(not going to the store every day) and with less waste because there's only so much food I can eat in a given time -> means I can follow a more varied diet in practice -> better health outcomes.

Now, if there's a specific problem with one preservative or other additive, fine. replace it with something else.
