Edit: Found it. https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml... (thanks to @crummy for the correction). Seems like a reasonable start. Amusing to see that alcoholic drinks are specifically not considered ultra-processed foods for the purposes of school meals!
> In July 2025, the federal Centers for Disease Control (CDC) reported that 32.7 percent of children and youth between 12 and 19 years old are prediabetic.
Wow.
- Unprocessed or minimally processed foods (fresh or frozen products, yoghurts, etc)
- Processed culinary ingredients (oil, vinegar)
- Processed foods (foods created from combining elements of the first 2 groups using typical cooking processes, like bread, pasta, some meats, canned vegetables)
- Ultra-processed foods (foods requiring industrial processing).
Flour is minimally processed, Nova Group 1, if it’s simply milled and separated. If it’s prepared with industrial solvents, or bleached, it goes straight to Group 4.
Nova doesn’t distinguish between ingredients and food [1]. (It needs to be able to do this. UPFs are defined, in part, by almost lacking low-Nova inputs.)
[1] https://en.wikipedia.org/wiki/Nova_classification
Cooking it first is a big improvement, but the same is true of carrots, IMO.
Bread is made from dough, which is mainly made from flour (the "minimally processed" food), which is made from grains (the unprocessed food)
“Traditional methods to puff or pop rice include frying in oil or salt. Commercial puffed rice is usually made by heating rice kernels under high pressure in the presence of steam, though the method of manufacture varies widely” [1].
If I had to guess, the commercial stuff is more thoroughly and homogeneously gelatinized. That, in turn, probably raises its glycemic index.
[1] https://en.wikipedia.org/wiki/Puffed_rice
No. Processed culinary ingredient (Group 2) and minimally processed (Group 1). (Obviously, both can be turned into a UPF through fuckery.)
"Minimally processed foods, that together with unprocessed foods make up NOVA group 1, are unprocessed foods altered by industrial processes such as removal of inedible or unwanted parts, drying, crushing, grinding, fractioning, roasting, boiling, pasteurization, refrigeration, freezing, placing in containers, vacuum packaging or non-alcoholic fermentation. None of these processes add salt, sugar, oils or fats, or other food substances to the original food." https://pmc.ncbi.nlm.nih.gov/articles/PMC10260459/
Too minimally processed-I’d say it’s Group 1. You’re taking Group 1 ingredients (avocado, jalapeño, lime, onion, maybe tomato and cilantro) and chopping, squeezing and pounding them. It can entirely be done with stone tools.
Salt is the Group 2 ingredient that I was mentioning. Nova calls out adding salt or sugar to Group 1 makes it Group 3, and specifically calls out Group 1 does not contain added salt.
"Minimally processed foods, that together with unprocessed foods make up NOVA group 1, are unprocessed foods altered by industrial processes such as removal of inedible or unwanted parts, drying, crushing, grinding, fractioning, roasting, boiling, pasteurization, refrigeration, freezing, placing in containers, vacuum packaging or non-alcoholic fermentation. None of these processes add salt, sugar, oils or fats, or other food substances to the original food." https://pmc.ncbi.nlm.nih.gov/articles/PMC10260459/
These are unprocessed foods [1].
From them you get processed culinary ingredients, like olive oil, vinegar, honey and butter. As long as you’re minimally vigilant with these, you should be fine, though some production methods may still add preservatives or use solvents in their manufacture.
After that one has processed foods, which may still have a good amount of Group 1 and 2 ingredients, before we get to Group 4, UPFs, what California is banning in school lunches.
[1] https://en.wikipedia.org/wiki/Nova_classification
For me, processed food might include something like unsweetened peanut butter where while the only ingredient is peanuts, it's still been through a process of grinding so that it's no longer in its natural form.
At the other end of the spectrum an example of ultra processed food would be a factory packaged item with a long list of ingredients which includes ones you don't recognise e.g. chemical names or E numbers.
Depends on if they’re ultra processed or not.
If they won’t stale for weeks, they’re ultra processed with preservatives and/or solvents. If they go stale and have a simple ingredients list, they probably aren’t.
(And kids don’t need to be habituated to having either with every lunch.)
So no, it’s a lot more arbitrary than that.
Sure. But they’re commonly in kitchens and simply produced, making their status as Group 1 and 2 Nova foods unambiguous.
When a grandma bakes some cookies for their grandchildren she uses only some basic ingredients - eggs, flour, butter, sugar.
For the product that food industries calls as cookies however, the list of ingredients looks like a git SHA.
Look into the process used to make soybean oil vs the process used to make butter.
> The E.U. says that if they can’t dismiss the possibility of harm, they can’t find an additive safe,” Galligan says. In the U.S., the bar is much lower; companies can add new ingredients to their foods without even informing the FDA. “In the U.S., it feels like the FDA is waiting to act until harm is definitely proven,” says Galligan.

> (3) (A) High amounts of saturated fat, sodium, or added sugar, as defined respectively as follows:
> (i) The food or beverage contains 10 percent or greater of total energy from saturated fat
I feel like the saturated fat limit would be the most impactful restrictions.
However right after it's entirely opened up again:
> (b) “Ultraprocessed food” or “UPF” does not include any of the following:
> (1) Commodity food specifically made available by the United States Department of Agriculture.
> (2) A raw agricultural commodity as defined in Section 110020.

Excess sugar and simple starches tend to get absorbed more completely than excess fat, I'm not sure added fat is the biggest issue.
However, there is a preponderance of real data that fats have been demonized by the sugar industry in the past, and HGI foods (high-carb, generally) are a bigger issue.
https://www.npr.org/sections/thetwo-way/2016/09/13/493739074...
But the jury is still against too much saturated fat, since the lymphatic system doesn't handle it in the healthiest of ways. So limiting saturated fats is still the WHO recommendation.
wonder who'll be the first to argue that HFCS isn't sugar.
That aside, I think the law is a great step in the right direction for the US.
Hopefully it can be expanded across the US.
Also as quoted elsewhere: Deep frying is ultra-processing?
If the thing that is bad for us is the processing and preservatives then we can pursue that... but if you want to count things like potato chips then we need to be honest about what the label actually means. The UPF label adds a veneer of scientific precision that isn't actually present in any guidelines surrounding it.
The seed oil panic is even more ridiculous than the UPF panic.
Potato chips are junk food. The important thing is that they aren't ultra-processed in a meaningful sense. What people want to mean when they say "ultra-processed" is actually "junk food." This is why people end up bending over backwards to find a reason to label ice cream and potato chips as "ultra-processed" so it can be a cure-all solution when reality isn't so simple.
In the case of potato chips though, I specifically disagree that they aren't ultra processed - look into the process for creating soybean or canola oil and try to explain how that isn't "ultra processed".
further thinking along these lines:
Consider a boiled potato. That would generally be considered healthy.
Now add butter to it. Those who think saturated fat is unhealthy would say it's unhealthy, I'd say it's healthy - though sure, fat generally has more calories per micronutrients so you also need to get your micronutrients somewhere, like by eating lots of greens too. And with caveat that butter from conventional cows can have issues like the hormones or medications but I haven't dug deep into that. And there are people who have sensitivity to dairy, etc. But for a normal healthy person, adding lard, or butter, or real unrefined coconut oil, or real unrefined olive oil to one's potato while increasing the calories doesn't itself make it junk food or unhealthy.
Frying it could be an issue, proportional probably to the amount and intensity of frying, though I'd argue much more so in cases where the frying oil is reused, as reused frying oil is going to be much more oxidized and thus cause more oxidative stress / free radicals in the body which are understood to be a big cause of metabolic / mitochondrial damage which lead to diseases like diabetes.
And there's one of the nuances - different fats are more or less easy to oxidize. Specifically, saturated fats are the hardest to oxidize, omega 3s are a little easier to oxidize, and omega 6 (polyunsaturated fats / PUFAs) are much easier to oxidize. You can verify this by looking into the chemistry a bit. That's one of the key mechanisms of action as I understand it.
Still, deep frying in tallow that has been reused for a week is still going to be really bad because tallow does still oxidize, just much less readily than PUFAs.
Refined PUFAs are heated several times during the processing, which causes oxidation. Not to mention antioxidants are removed by the process, and also the PUFAs themselves are more prone to oxidize in the first place.
So to recap: 1. boiled potato = fine 2. boiled potato with added butter = more calories per micronutrient, but still real food and no particularly bad thing in it 3. potato pan fried in [butter, lard, tallow, coconut oil] = more oxidative stress than above, but still probably not terrible considering pan frying food is very normal. 4. potato deep fried in [butter, lard, tallow, coconut oil] that has been used repeatedly = significantly more oxidative stress, would not recommend, maybe I'd call it junk food 5. potato deep fried in [soybean oil, canola oil, etc] = significantly more oxidative stress again than #4
This does not yet get into the other potential issues with refined oils: - hexane residue (people eat average of 25 to 250mg per year of hexane in the US in refined oils) - may not matter at all but still something weird about the food. - other chemical residues from the other processes
If it's spread on bread, the jellied bread is the food. (As that still is probably mostly carbs, it's still not a good lunch item for kids.)
“ultraprocessed food” or “UPF” means (any food or beverage that contains a substance described in paragraph (2) and either high amounts of saturated fat, sodium, or added sugar, as described in subparagraph (A) of paragraph (3), or a nonnutritive sweetener or other substance described in subparagraph (B) of paragraph (3)).

Brilliant sleight of hand by the processed food industry.
Of the fats one can eat, saturated fat is generally the least processed and most natural.
Humanity has eaten saturated fat for ever. Refined/processed oils are a completely new thing that has become a staple of the modern industrial diet. Under this law kids will be made to eat more of the ultra processed literally refined oils and less natural fat.

So ... flour? Actually healthier things with scarier names like xanthan gum?
> Commodity food specifically made available by the United States Department of Agriculture.
Which I'd guess includes flour.
[1] https://www.fns.usda.gov/csfp/commodity-supplemental-food-pr...
Does this count if they supply it from a vending machine on their premises :-)
If used as a thickener, perhaps.
> Actually healthier things with scarier names like xanthan gum?
This would almost certainly fall afoul of these rules. And with good reason. Xantham gum is fine per se, but it tends to help unhealthy food stay together. I don’t see why a school kitchen needs to serve anything thickened with it.
I would gander you have little to no experience in the kitchen. Literally ANY sauce? Basically any Asian cuisine. Soup? Do you eat soup?
Keep ganderin’.
> Literally ANY sauce? Basically any Asian cuisine. Soup?
None of these need to be thickened with xantham gum…
I think one could make xantham gum as a processed culinary ingredient (Nova group 2) ingredient, so long as it isn’t packaged with preservatives.
The bill itself calls out using USDA databases for various ingredients and various sections of federal regulations, so I can't comment too much about how they'd feel about xanthum gum without diving deep. Not to go off on a tangent, but just from the bill's text, I can say for sure they don't like nonnutritive sweeteners, which I think really hurts diabetics choices at reducing their reliance on insulin while still enjoying nice treats. Although not too important for a school meal, it's definitely part of the ultra processed conversation and why it's not a simple thing to categorize food into groups.
For reference: xanthan gum specifically would fall afoul of the rules, as... a (ii) stabilizer or thickener, (iv) coloring or coloring adjunct, and (v) emulsifier.
https://www.hfpappexternal.fda.gov/scripts/fdcc/index.cfm?se...
It's quite silly that it's classified as a coloring agent and an emulsifier, when it's neither of those things.
Common culprits include chemicals added during the bleaching process and addition of "enzyme" / other ingredients that help improve baking consistency. Some examples:

I'm sure they extensively deliberated the health effect of Luo Han Fruit Concentrate and Maltitol
There is plenty of data showing diet has a big impact on health and other outcomes, yet far less data on specifics.
Since science doesn't give specific things to ban, legislation is pretty much headed towards "let's have everyone eat what they eat in the south of France where people are really healthy".
The problem isn't the MSG. It's providing a well balanced diet. We have a relatively clear idea of what constitutes "well balanced". You can quibble about the specifics but this bill is fundamentally off on a crazy unscientific tangents.
There are just three lines that actually address nutrition:
(i) The food or beverage contains 10 percent or greater of total energy from saturated fat.
(ii) The food or beverage contains a ratio of milligrams of sodium to calories that is equal to or greater than 1:1.
(iii) The food or beverage contains 10 percent or greater of total energy from added sugars.
Instead of paragraphs of banning the "scary chemicals", why not work on making sure kids get the vitamins, vegetables and fiber they need in each meal. I'm not a nutritionist, but there are some basics that are braindead simple that don't involve banning Sucralose.
Interestingly, dairy products like butter are explicitly allowed, despite the fact that 50%+ of its fats are saturated
> I'm not a nutritionist, but there are some basics that are braindead simple that don't involve banning Sucralose.
I'm in favor of banning artificial sweeteners. Just look at why they are used in animal farming to see why it is a bad idea to randomly add them to human food.
If someone is habitually consuming sugar sweetened beverages, replacing those with ASBs will, the evidence strongly suggests, reduce your risk of obesity and various chronic diseases.
We can say "just don't consume either" but we have decades of attempting such policies that shows people don't work that way. Someone who wants to drink a can of coke will drink a can of coke, why would we ban the healthier option?
https://doi.org/10.1001/jamainternmed.2019.2478
It was suggested elsewhere that the primary mechanism for soft drink associated mortality is acidic fluids causing tooth decay, which in turn causes cardiovascular disease. (Bacteria entering the bloodstream through inflamed oral mucosa, and forming plaques along arterial walls.)
And the evidence for artificial sweetener benefits on population level is practically non-existent. In fact animal farming points to a detrimental effect.
When we do that we pretty consistently see benefits. Good overview as a response to the WHO position paper here that goes over that evidence base: https://mailchi.mp/b30c80ddf8ba/who-as
But all empirical observations so far show that artificial sweeteners in people's diets do not have the desired effect when people's food and beverage intake is uncontrolled.
In fact results from animal studies are that you can even substitute part of the feed with just the artificial sweetener to achieve the same body mass gain. And this is known since 1960s with Cyclamate and rats: https://doi.org/10.1038/221091b0
More studies in the meantime varied a bit on the size of the effect, and some were inconclusive, but generally the results held up.
So no, artificial sweeteners do not help to manage weight. What the studies actually show is that controlling people's intake does.
I'm saying this as someone who rarely consumes these things..
> Just look at why they are used in animal farming
I don't know anything about the science behind that - so I'm not in a position to judge. Did they try every possible "artificial sweeteners"? How about if there is another one discovered next year? Is it going to be pre-banned even if it doesn't have these drawbacks?
These aren't like the same substance tweaked a bit where you're in a endless ratrace with the chemists.
We are talking about school lunches here. Sweet meals are bad (whether sugar or artificially sweetened) as it trains children's palate and shapes lifelong preference for sweet food. Hence I support banning artificial sweeteners as California plans to do.
When it comes to sweetened drinks, switching from sugary to artificially sweetened is not empirically shown as beneficial. This is the hurdle that proponents of public health interventions to replace sugar with aritificial sweeteners need to overcome.
> Did they try every possible "artificial sweeteners"?
The study which I linked in another reply looked at various commercially available artificial sweeteners and some combinations. https://doi.org/10.3390/ani14203032
This is necessary because not every species' taste receptors respond to every type of sweetener, e.g. rats do not respond to NHDC.
> These aren't like the same substance tweaked a bit where you're in a endless ratrace with the chemists.
Well it depends on who has the burden of proof that a certain food additive is safe and does not cause undesired long term effects, especially in children.
- every meal is served with white rice ("empty calories")
- every meal is served with Kimchi (high sodium)
- most dishes are flavored with soy sauce, gochutan, rice syrup... they are extremely high in sodium + msg
- people love fried chicken with syrupy sauces
- korean barbeque is popular, with very fatty cuts (pork belly etc.)
Pretty much all of those foods would be considered unhealthy, but somehow Koreans don't seem to suffer from obesity like US + Europe do, I have no idea why.
I think most people who are thin just have a food intake regulation that is pretty well balanced so they don't over eat because they don't feel that hungry when they have had enough calories.
The reason why some groups of people have been increasingly prone to obesity is external factors interfering with that regulation. It's probably lots of things, food availability, ingredients, cost, culture, other mental health issues, medications, entertainment, work, availability of cars. One thing it is not is simple.
The calories in vs calories out mechanic is simple, the reasons why that's going out of kilter is not.
I loved the food, but it was not at all what anyone would consider healthy.
(Instant Ramen are also extremely popular, industrially produced fried noodles with way too much saturated fats + sodium)
The question is why they have better balanced calorie intake. It's certainly not lack of sugar availability.
Not sure if there is any truth in that.
Every meal must contain more empty calories than everything else combined, but not in an excessive amount.
I do not know about Korea, but I have been in Japan, where also every meal is served with excellent white rice. However, there was never too much of it and in general the quantities of all ingredients were right for a balanced diet, much more so than I have seen in most other countries.
Second, I do not know whether there are some Korean diets that are more correlated with obesity. In Thailand, people eat much the same, and they are more often obese on the global scale. Less kimchi, though, and probably more coconut milk and sugar.
Simple diet composition is probably not the main factor in obesity. I do notice that "normal" portion sizes are pretty small in Korea, based on what I see in their media. Even feasts are shown to have reasonable portion sizes. In the US, portion sizes tend to maximally fill the stomach, and have grown considerably over the years.
Highly processed foods are generally designed to add addictive properties and cause overconsumption. I am not sure that's the goal of the Korean dishes you have tried. If we understand what the new weight loss drugs are telling us, we can see that increasing satiety faster with fewer calories should be the goal of our foods. (no citation, just my interpretation of what's going on).

Part of the problem is the logistics and financing of school and generally cantina meals.
Unlike restaurants which can command high meal prices for artisans preparing meals out of ingredients as close to "fresh from the field" as possible, mass kitchens face insane cost pressure, which often means going for pre-processed food with very long shelf lifes for packaged units to keep waste as close to zero as possible.
Generally, I love to point at tomatoes when talking about food access and quality... for one, most tomatoes you can buy these days are grown in greenhouses with artificial light and bred to have pretty robust skin to avoid damages in shipping and storage, at the cost of flavor. As an individual making a tomato salad, you can mask off that lack of flavor by just dumping balsamico, olive oil, salt and pepper over the tomatoes... but if you are making, say, a tomato soup in a large ass kitchen for pasta, you'll probably go for the ultra-processed variant from a can or tub: no need to have employees cut up and mash tomatoes, it will keep fresh for far longer than if you'd send someone to the wholesalers to buy tomatoes every day...
And the truly ultra large kitchens that make meals for thousands of school children (or prisoners or hospital patients) a day, they probably go for the even cheaper variant and that's where the problems really show - entirely premade tomato sauce, filled with preservatives to prevent the sauce from going bad, with tons of sugar and flavorings to make it palatable (as the source tomatoes are going to be the cheapest, lowest quality, flavorless tomatoes the original processor can find), and quite possibly with a bunch of food dyes on top to appear "healthy red like a good organic tomato".
Exactly. Science can’t give us actionable information, so appeal to established practice it is.
They fuck up your microbiome and the insulin response. There is absolutely no reason to use them ever. Grow up and embrace the bitterness.
Worse is that artificial sweeteners increase feed conversion efficiency (an effect which has been known since 1960s experiments with rats and Cyclamate), and are for this reason frequently added to animal feed.
For humans however this effect is undesirable, as it exacerbates the problem which they are supposed to solve.
What impact would pouring a bunch of refined sugar on animal feed have on feed conversion efficiency?
What do studies on humans say on the actual real-life effects of people using artificial sweeteners instead of sugar?
If you permit me to be a bit glib, if we outlawed everything that people think tastes good, almost no one would overeat, and we would have solved obesity. Without going to that extreme, surely there are other interventions that can help limit the problem of overeating, and isn’t there evidence that artificial sweeteners are actually helpful in doing that? Remember that the starting point for humans isn’t hay and the slop we feed to pigs, it’s ice cream and McDonald’s.
No, not at all.
Feed conversion efficiency is the body weight gained per unit of feed consumed. If you add artificial sweeteners to animal feed, they will gain more weight when consuming the same feed, or gain the same weight when consuming less feed. This leads to cost savings for the farmer.
This observation may be a bit surprising as artificial sweeteners have 0 calories. But then again, antibiotics and growth hormones have the same effect.
> What do studies on humans say on the actual real-life effects of people using artificial sweeteners instead of sugar?
When it comes to soft drinks and all-cause mortality, artificially sweetened is not better nor worse than sugar. https://doi.org/10.1001/jamainternmed.2019.2478
When it comes to weight, results are either neutral or inconclusive.

But of course the manufacturers of feed additives also extensively studied which artificial sweetener compositions achieve body mass gain / feed efficiency increase for which group of animals. There is an extensive review e.g. on pigs here:
https://doi.org/10.3390/ani14203032
Someone who wants to drink a can of coke will drink a can of coke, why would we ban the healthier option?
That’s not really the case when discussing school meals though, when kids will generally be eating what is put in front of them.
Subjectively, a few months of wearing a monitor appeared to show no perceptible effect on my own.
The countries that consume the most processed foods are also the longest lived, obviously such a correlation does not imply processed foods lead to longevity, just that any accusation of cause and effect is more easily explained by abundance and affluenza (sic).
How long before the UPF cult proclaims vaccines are poison, I note than some of their number already do.
There is a connection between ultra processing and hyper-palatability, but it is a very lossy one. Doritos are ultra processed but no honest definition of ultra processed foods can include Fritos. Are Doritos substantially worse for you than Fritos?
Is ice cream ultra processed? There are definitely ultra processed ice creams you can buy, with lots of stabilizers or whatever. But you can also make ice cream with just cream, milk, sugar, and vanilla beans. If anything, the homemade stuff that isn't ultra processed is even more hyper-palatable than the "frozen dairy dessert" kind.
The ingredients in Fritos are corn, oil, and salt. What processed additives? Is extruding cornmeal mixed with water through a die ultra processing?
This is spinning wildly into seed oil crank stuff.
Do you know how canola oil is made?
Not unsurprisingly, most of those changes use fancy processes and ingredients to mimick other ingredients and processes.
Legislation like this is saying "enough, you can only use the following set of processes". If that results in some hypothetical healthy food being banned, so be it, but really this is about a loss of trust.
What’s “processing”?
> The food industry has demonstrated that it doesn't give a crap about producing healthy food if that impacts the bottom line, so they pull every trick they can to increase profits whilst hiding the changes from consumers' ability to detect them
Ok? What’s that got to do with which forms of processing are unhealthy? This whole statement doesn’t really add anything.
> Not unsurprisingly, most of those changes use fancy processes and ingredients to mimick other ingredients and processes.
So it’s the “fancy” part you don’t like? What does fancy mean? You can quantify it, I’m sure?
> Legislation like this is saying "enough, you can only use the following set of processes".
Right, and as GP pointed out, the following set doesn’t seem to be particularly healthy.
The point of anti UPF sentiment isn't to be healthy per se, but to remove the disconnect between food as most people understand it and we evolved to handle and what is typically produced in industrial kitchens.
The idea that we can process our way to a healthy diet has not stood up to the real world experimentation. Maybe it's time to stop experimenting on school children and just accept that perhaps they should be fed food that is generally recognised as such down to its base ingredients.
The whole discussion here is how the legislation's definition is lacking, because it excludes otherwise perfectly healthy foods.
You tried to clarify it by saying "it's about processing", and when pressed, said the definition is what the legislation says it is.
You see how this is circular?
> By and large it's ingredients most people use and recognise in their own kitchens
I have MSG in my kitchen. Does that make it ok then? An "ultra-processed" food becomes "ok" if people just... see it more often?
This is exactly the sort of blanket BS the OP was talking about.
That said, we can look at proxies like "what do healthy people tend to eat more of?", and the clear evidence is that people that are healthy by and large have diets that are low in UPFs and high in home prepared food. Of course, this could be a correlation, but until we have this properly established, the precautionary principle would be that we shouldn't eat too much in the way of UPFs, because that necessarily also implies food prepared and cooked in a way we know to be correlated with health. We certainly shouldn't be pushing it on our children.
There's no circularity. You asked me what processing meant and I said what it says in the legislation, which is pretty similar to the Nova classification. That definition was used because it's broadly useful without being overly restrictive.
By all means use MSG - nobody is stopping you. But there's a good hypothesis that MSG is problematic precisely because it is one thread of hyper-palatable food. Of course soy sauce or miso contain plenty of MSG (or at least a close analogue), but they also tend to influence flavour so are hard to use to excess; they also cost more so there's an cost pressure to limit excessive use.
Wholemeal bread with soya lecithins? Evil UPF, ban it.
Artisinally produced sourdough using refined flour with tons of salt but no lecithins? Delightful, fill your boots.
We've let nutrition policy become controlled by fad diet book authors and the results aren't pretty...
Outside of causing an imbalance (which would require a LOT of salt), there’s nothing bad about a lot of salt. People have been eating tons of salt for centuries.
> refined flower
Not sure what definition you’re using here so this might not be ideal, but probably fine. People have been milling for centuries.
> soya lecithins
Made in a lab about 100 years ago, and its primary use is to increase profits via long shelf life (increasing shelf life could be a noble goal, ie freezers are great). We have billionaires flying private jets around. Redo some resource allocation and we don’t need soya lecithins.
Much modernity has 0 respect for Chestetons fence. On top of that, nutrition science is basically a social science in terms of accuracy (not a dig, it’s very hard). Many “advances” today are purely profit motivated and don’t pay enough respect to the people’s wellbeing. We should be skeptical of changes done to make the rich richer.
What’s your goalpost for evidence here, I.e. what would it take to convince you that salt consumption above the levels indicated in dietary guidelines is harmful?
Every study I've looked into that purported to show salt was a problem did not isolate salt, and the most likely reason IMHO that the "less salt" group did better was because they ate less ultra processed food and more natural food.
When we scale out to what I believe to be a superior intervention - replacement of sodium with potassium, we have really robust data. The SASS trial (https://www.nejm.org/doi/full/10.1056/NEJMoa2105675) showed reductions in stroke and CVD incidence from consuming salt substitute, along with reduction in all cause mortality.
I have a real salt taste - if I had no care for health outcomes I’d absolutely cover my food in it! However I think the evidence in favour of reducing or, ideally, replacing it with potassium-heavy substitutes is really convincing.
Having read the study now: DASH-sodium barely indicates anything about sodium independently. It looks at three biomarkers which _correlate_ with cardiovascular disease, and finds that reducing sodium from high to low levels for four weeks reduced one of those biomarkers by 19%, _increased_ another biomarker by 9%, and didn't change the third. You could say that this suggests higher sodium increases cardiovascular disease risk but that seems like a stretch when if you'd picked a slightly different set of CVD-correlated biomarkers you would have got exactly the opposite result.
Even if the results had been more convincing, the methods are not - it's an extremely short term study and looks only at correlative biomarkers and not at actual health outcomes. There's no meaningful way to quantify the impact based on this.
The potassium study is indeed interesting. It shows among people who already have CVD, a reduced risk of death of 12%. I think it's pretty well known that modern diets have a significant electrolyte imbalance, i.e. not enough potassium per sodium. I do supplement potassium for this reason sometimes and recommend it, though I'd prefer to just have a ton of natural nutrient dense food available and not feel like I need to. So we're in agreement on that one. That said I don't take that study to strongly show that sodium is a primary driver of CVD - it could just as easily be interpreted that the lack of potassium due to lack of real natural food is a cause of CVD (potassium being mostly in nutrient dense greens, and grass fed meat (i.e. animals that ate more natural diets i.e. greens)).
So, thank you - this helps my understanding of the whole topic - not that I know the answers, but it does make me more curious about sodium/potassium electrolyte imbalance being a factor in CVD. Ideally this would be fixed with a healthier diet but it can be hard/expensive to get enough nutrient dense foods.
Edit: oops - I missed the TOHP study - but that's one where they don't isolate sodium: > The active intervention, described in detail elsewhere,22 involved dietary and behavioural counselling on how to identify sodium in the diet, self monitor intake, and select or prepare lower sodium foods and condiments suited to personal preferences. Individual and weekly group counselling sessions were provided during the first three months, with additional counselling and support less frequently for the remainder of follow-up.
What’s the evidence for this?
> Even if the results had been more convincing, the methods are not - it's an extremely short term study and looks only at correlative biomarkers and not at actual health outcomes
You're going to have to pick your poison here - when you're after long term data on dietary interventions showing hard outcomes it's highly unlikely you'll ever see this in the form of RCTs that you're looking for (i.e. where you _only_ alter salt consumption). That's why we look for converging lines of evidence - biomarkers/soft outcomes from RCTs and hard outcomes from prospective cohort studies, for example. When we look at this for salt, we consistently see lower salt = lower adverse outcomes.
That said, when we meta-analyse RCTs we do actually have sufficient power to see improvements on hard outcomes. In this meta (https://doi.org/10.1016/S0140-6736(11)61174-4) we see a 29% reduction in cardiovascular events in the 7 months to 11.5 years in normotensives in RCTs which looked exclusively at salt reduction. I wouldn't call 11.5 years short term, nor cardiovascular disease events a soft outcome. So surely this ticks all your boxes?
Meta analysis is only as strong as the studies it's based on. I looked at quite a few studies before that purport to show sodium causing CVD, and none of them strongly support their conclusion - they all had significant flaws, not that they're not useful research just that they don't show what they are used to say they show.
For example, there were studies showing that increased salt increased blood pressure by ~5 mm Hg over long term. I understand that blood pressure can be affected very slightly by salt intake, I would guess because the body is holding more water or some other normal mechanism like that, but this does not suggest it's the long term cause of blood pressures going up from a normal 120 to a chronic 160 or 200 as we're seeing in tons of people. There could be any number of adjustments that would increase blood pressure slightly WHILE the change is in effect and then go back to baseline afterward. The chronic high blood pressure is a disease that doesn't just go back to normal immediately after a change.
Anyway, I don't have time at the moment to look through the 11 studies cited in that meta analysis, but if you pick the one or two that give the strongest evidence for salt causing CVD I'd look at them.
I'm genuinely trying to figure this out myself as best I can, because I know way too many people close to me dealing with early stage CVD and diabetes. And a lot of them say they're working on it by avoiding meat and dairy and eggs and salt, and instead of that they end up eating more refined oils and refined flour and sugar. It doesn't seem to be helping them any after years of this, and I think this is backwards advice. I'm not saying we need to eat tons of salt, maybe it does have a minor effect, just that it's not the real culprit.
Depends on
a) How well it's believed science is able to keep up with the "creativity" and dollars of the food industry.
b) The health costs to the individual and society of any subsequent problem.
c) How well the society in question is likely to do in overcoming the vested interests to fix any subsequent problem.
YMMV.
What? Are you talking about trans fats?
Since mid-1990s, margarine no longer contains appreciable amounts of trans fats.
Butter also contains trans fats but these are ruminant TFAs which I understand are not so bad.
This is why despite butter composition being worse "on paper" there is no empirical observation that it is less healthy than plant margarine.
> Wow.
Sadly, I'm not too surprised. My state also has free breakfast and lunch in public schools and it is possible for them to get served over 100g of added sugar between the two meals and classroom provided snacks. Then add to it whatever the kids are eating at home.
It also creates added difficulty for kids to concentrate on lessons when their blood sugar is spiking and crashing repeatedly throughout the day.
Doesn't mean we shouldn't try to offer healthy option, but just that those would have a limited impact on obesity, expect for maybe calorie deficit if they choose to forgo breakfast or lunch
When the option is some fried food vs a wilted salad with no protein source, it's a wonder that any kid would choose the salad.
I would love to see better options that are both healthy and enticing. Until then I doubt that we will see much change when the choice of what to eat in the lunch room is left to the children.
95% of the student body ate that pizza every single day.
This includes the supposedly "smart" kids in honors classes.
The real food was good! It was fresh and perfectly palatable and varied enough to be healthy!
Instead of eating it, the students literally invented a lie to hype up this disgusting facsimile of "pizza" as good. It was regularly claimed that this pizza came from a local small business that sold pizza. This was flagrantly wrong and obvious to anyone who had eaten that pizza, as they used a sweet sauce that was not used in the school pizza.
But what the actual hell do Americans expect? We spent decades disallowing the government from telling your kids anything useful, we opted out of "Only 12 minutes of advertising to children per hour on TV" because "regulation is bad", we built a society that advocates rampant consumerism to your kid from before they even can read.
Of course they're going to eat the shitty pizza. It's what consumerism tells people to do. In the US, consumerism is a literal lifestyle brand!
