I think the scientific community has done just fine. When these individual substances are tested they're by and large not found to have negative health effects. Then the loonies just refuse to believe it and thing the chemicals are making their kids gay.

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.



I went on a trip to South Korea recently. There are very few overweight people there. But the food that people eat doesn't seem healthy at all.

- 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.


It’s actually pretty simple. Despite what you’re calling unhealthy foods (I’d argue kimchi has health benefits from the fermentation), they have a lower overall caloric intake and societal pressure to conform to a thin appearance. If you want to be skinny eat less calories. If you want to be healthy, eat highly nutritious foods and the right amount of calories for your lifestyle.


I don't think a large proportion of thin people are thin because of societal pressure. And conversely I don't think societal pressure makes many people thin, because I hear so much complaints about body shaming and unrealistic beauty expectations and discrimination against obesity etc, so it clearly isn't working any miracles.

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.


Asians dont consume the same amounts of sugars. its that simple. they also tend to exercise more.


Rice syrup + corn syrup are used in pretty much every savory dish, subway stations often have a bakery that sells sweet pastries (filled with bean paste), Starbucks style coffee drinks are also popular, people snack dried octopus (loaded with salt + sugar)...

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)


It's total calories, not just calories from sugar. And I already said that part of it was simple, remember? It's in the post you're replying to!

The question is why they have better balanced calorie intake. It's certainly not lack of sugar availability.


I am not sure there is a strong societal pressure to be thin. Last several years, sure. But older generations, nor so much (see deities in any buddist temple). And there was enough time after food became abundant for the older generations health to tank if that diet was very bad for them. My 2c.

Koreans intensely shame each other about gaining weight, which helps people control calories in and calories out. East asians eat very little food. Tik Tok is full of videos of Chinese making fun of Japanese for their “sad, tiny lunches.”


A few things come to mind. First, South Korea has low obesity on the global scale (BMI >= 30 kg/m2) but within the country [1] they use an "Asia-Pacific" scale for the definition which starts at BMI of 25. [2] So, from the Korean perspective, they have substantial obesity.

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.

The quantities of those ingredients are what matters most.

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.


I have read somewhere (on HN?) a hypothesis that such traditional diets pretty quickly wipe out genetic lines predisposed to diabetes, etc. And that the effect is not diet, it is genetics+diet.

Not sure if there is any truth in that.


> The problem isn't the MSG. It's providing a well balanced diet.

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".


> (i) The food or beverage contains 10 percent or greater of total energy from saturated fat.

Interestingly, dairy products like butter are explicitly allowed, despite the fact that 50%+ of its fats are saturated

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.


As I wrote elsewhere:

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?


The evidence actually suggests that soft drink consumption is equally associated with higher all-cause mortality and artificially sweetened is every bit as bad as sugar sweetened. Even when controlling for smoking status, BMI, physical activity, and alcohol consumption.

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.


You have to be very specific in the intervention you’re either looking at in an RCT or modelling in a prospective cohort study. We wouldn’t expect adding NNSs to a diet to improve much (perhaps some benefit from carbonated ones on body mass). We need to investigate/model replacement of SSBs with NNSs.

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


Yes, replacement can work to adjust weight trends in a controlled setting.

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.


Let me get this straight: your epistemic framework is such that when presented with RCTs in humans showing positive effects, observational studies in humans showing null findings (likely because of poor adjustment models) and negative associations in rats, we should conclude “artificially sweetened is every bit as bad as sugar sweetened”?


No. What I say is if we introduce a public health policy, then we need to take human behavior and adherence rates into account.

Example: Abstinence is 100% effective against STDs and teenage pregnancy in any controlled setting. That does not make it a good public health policy to tell teenagers to abstain from having sex. In fact despite condoms having lower efficacy than abstinence, teaching people the proper use of condoms is overall more effective.

If we want to solve obesity then randomly adding/substituting artificial sweeteners to human food will not work. Instead we need to reduce access to hyperpalatable foods, which can be done through economic means (e.g. taxes).


Ok, so if I understand correctly, your argument is: in order for you to support a public health intervention we need to see evidence that such an intervention results in positive outcomes in a free living population with ad libitum consumption, regardless of the evidence in controlled settings.

So what’s the evidence that banning artificial sweeteners leads to positive outcomes in a free living population, considering you said: “I'm in favor of banning artificial sweeteners”?


> So what’s the evidence that banning artificial sweeteners leads to positive outcomes in a free living population, considering you said: “I'm in favor of banning artificial sweeteners”?

It depends on the context. In the context of school lunches (which is discussed here) they absolutely need to be banned, same as added sugars. Giving children (sugar or artificially) sweetened meals trains children's palates and shapes lifelong preferences for sweet foods.


Ok, so we already have your standard: in order for you to support a public health intervention we need to see evidence that such an intervention results in positive outcomes in a free living population with ad libitum consumption, regardless of the evidence in controlled settings.

We have your proposed intervention: “In the context of school lunches (which is discussed here) [NNS] absolutely need to be banned, same as added sugars.”

So now we need evidence supporting this intervention sufficient to meet your own goalposts. Do you have it?


> Ok, so we already have your standard

Who is "we"?

I don't know what you are going on about. Empirical evidence is one thing, mechanism is another source of knowledge by which we can shape public health policy. While empirical evidence is valid only for the situation in which it was obtained, mechanism is universal.

For example, we mandate wearing seatbelts in cars in the name of public health. It is however not necessary to do seatbelt on/off RCTs with actual people. How we know that this is beneficial: Because physics, verification through crash tests (with dummies), and because we know that seatbelt mandates increase the frequency of people wearing them.

Going back to the original question, it was clearly shown in observational studies that giving children sweetened food is bad: Childhood dietary habits shape lifelong food preferences, and preference for sweet food leads to worse outcomes regarding chronic diseases later in life. This has been shown in lots of research, both in humans and in animal models:

https://doi.org/10.1126/science.adn5421

https://doi.org/10.3390/nu16030428

https://doi.org/10.1093/chemse/bjr050

With randomly adding or substituting sugar with artificial sweeteners there is however no empirical evidence nor known mechanism which supports a public health benefit. In fact the mechanisms we know from animal farming suggest a detrimental effect.


> Who is "we"?

Me and anyone else reading this.

> While empirical evidence is valid only for the situation in which it was obtained, mechanism is universal.

Mechanisms are inferred from empirical evidence, I don't see how you can treat them as two separate categories. For example, in your crash test dummy analogy, verification through crash tests (with dummies) is empirical evidence. Yet under your framework, should we assume that it is valid only for the situation in which it was obtained - only for dummies, not people; in cars pushed towards walls in controlled situations, rather than on public roads?

If you name proxy experiments that support your views (crash tests) as mechanisms and ones that don't (SSB replacement with NNS RCTs) as "empirical evidence is valid only for the situation in which it was obtained" then sure, everything you want to believe is supported by sound science and everything you don't isn't. But the view itself seems to contain a logical contradiction, so you're dead before you've even got off the ground.

I would understand mechanistic evidence in the domain of health science to be in vitro and animal studies. Even if we were to grant that mechanism is universal in this field (which I wouldn't, we frequently see heterogenous results even within the same exposures on the same mouse models, for example), there are thousands of mechanisms that come together to influence the outcomes we actually care about. This is why when we look at translation rates of mechanisms to outcomes in humans we typically see rates below 5% (and is also why pharmaceuticals that work perfectly in animal models barely ever make it to market in humans).

Going back to the evidence you've cited in support of your intervention - the first two (the only ones in humans) are neither looking at NNSs nor an intervention on banning them. So it doesn't meet your own goalpost for "if we introduce a public health policy, then we need to take human behavior and adherence rates into account". In the rationing example, you have an entirely different context - one in which people literally cannot purchase large amounts of sugar. This would not be the case if we were to ban NNS today.

Your third study was in mice which, as discussed, has an incredibly low chance of actually translating into human outcomes. I don’t find “we have evidence in RCTs that NNSs are beneficial but there’s this mouse study that says otherwise so let’s ban them” a convincing argument.

So again, any actual evidence in support of your proposed intervention? How do we know, for example, that banning NNSs won't just lead to higher sugar consumption and adverse outcomes, since we know from RCTs that substituting SSBs for NNSs improves health outcomes? If all those consuming your banned substance now switch to SSBs instead of their NNSs, congratulations, you've just worsened health outcomes.


> Me and anyone else reading this.

In that case, no "we" don't, because I am reading this and I do not agree with this "standard" nor your characterization of what I wrote.

> Mechanisms are inferred from empirical evidence, I don't see how you can treat them as two separate categories. For example, in your crash test dummy analogy, verification through crash tests (with dummies) is empirical evidence.

This is not how it works. Crash tests are used for validation, but the data from crash tests is generally not used to infer mechanism. Physicists don't come up with a new theory of mechanics every time a crash test has an unexpected outcome.

> If you name proxy experiments that support your views (crash tests) as mechanisms and ones that don't (SSB replacement with NNS RCTs) as "empirical evidence is valid only for the situation in which it was obtained" then sure, everything you want to believe is supported by sound science and everything you don't isn't.

I don't think you understand. If you want to support a public health intervention you either have the empirical data with a relevant endpoint,

or you can point to mechanism which bridges the part between the data that you have and the outcome which you want to achieve.

When it comes to pharmaceutics and food additives, our mechanistic understanding is insufficient so we often have to resort to empirical studies on humans, including RCTs (Pfizer's Covid vaccine trial had tens of thousands of participants) and also observational studies at population level. And it is the last part where artificial sweeteners fail to show benefit so far.

When it comes to seat belts, our mechanistic understanding is sufficient so we don't need to resort to empirism. Yes we perform validation but only to check if there are no design oversights in the vehicle nor shortcomings with the simulation software, typically in a low triple-digit number of crash tests. But no humans involved and especially no control arm with humans.

(Well if you ignore the one study on the efficacy of parachutes which was done as RCT https://doi.org/10.1136/bmj.k5094 )

> So it doesn't meet your own goalpost

It does, because again, mechanism is provided. You could say that the study has weak evidence for the mechanism and it works like that perhaps only for sugar. Because that some mechanism is found in mice does not mean it is also found in humans, and it would be a fair point. This is why many species are tested and so far the results held up (testing humans takes too long for obvious reasons).


Sorry, I summarised what I thought was your goalpost earlier in the exact same words and you didn’t correct me, so I made the assumption in subsequent replies. I’m not interested in straw manning your argument, just trying to understand.

I’m going to pass on the crash test dummies bit. You’ve misunderstood the point I was making, but it could be poor communication by me and I think the point is becoming increasingly tangential.

This is why many species are tested and so far the results held up (testing humans takes too long for obvious reasons).

So you don’t feel you’re being straw manned again, can I get a clear answer to this: is your argument that if we stack together sufficient numbers of mechanistic animal studies we can be sufficiently confident enough in the translation rate of such studies to humans that we can roll out public health interventions without any evidence of efficacy in human populations?


The fact that you want to ban everything under the umbrella term of "artificial sweeteners" is why I think you have a fundamentally unscientific approach. Your other responses seem to suggest you just have something against sweet things (even when you seem to acknowledge there are other factors at play like acidity and tooth decay)

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.


> Your other responses seem to suggest you just have something against sweet things (even when you seem to acknowledge there are other factors at play like acidity and tooth decay)

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.
