Likewise breakfast yogurt could be either yoplait “yogurt” or plain unsweetened actual yogurt, or anything in between.

One is basically gelatinized sugar and the other is pretty healthy. If one’s classification doesn’t easily distinguish those two, that’s absurd.

No, it does not, since ultra-processed, though not a strictly defined term, does not include household ingredients like granulated sugar or brown sugar. If you happen to have a jar of HFCS in your cabinet then that would quality.

Well then it is a worthless term. Both granulated sugar and HFCS are processed foods. Corn syrup is a household ingredient. No idea why you think a bit higher percentage of fructose changes anything.

neomantra 1 day ago

Corn syrup and high-fructose corn syrup are two different ingredients, although they share some words. One is 100% glucose and the other also contains fructose (usually 42% or 55% fructose), produced by chemically altering the corn syrup. We process glucose and sucrose differently and it affects taste, satiation, digestion, and more. I agree that the terminology is useless, by institutional intention.

epcoa 1 day ago

> chemically altering the corn syrup.

And where does corn syrup come from? From squeezing corn? The sugars in corn don’t start as glucose either (they’re starches).

Besides, at home, bakers easily make “HFCS” themselves by adding any weak acid to table sugar to make invert sugar (an HFCS 50 equivalent).

> We process glucose and sucrose differently

Tell that to some southerners about their sweet tea. This simple distinction isn’t that metabolically interesting for day to day life (or explaining the prevalence of obesity and metabolic syndromes). Concentrations in a serving and mode of delivery are far more important. You can pretty easily get metabolic syndrome from excess glucose as well as sucrose. Altering smell and moisture content are more impactful variables.

Sucrose readily hydrolyzes to glucose and fructose via sucrase in the small intestine, it and HFCS become equals (no, Mexican coke isn’t healthier you dumb hipsters, just eat a piece of fruit already). If it wasn’t you’d get massive diarrhea from eating it. So sucrose vs HFCS isn’t nearly as distinct.

> and it affects taste, satiation, digestion, and more.

The most important distinctions go beyond the relative concentrations of the simple sugars. A fresh fruit doesn’t have the same insulin spiking and metabolic syndrome inducing potential as plain Karo syrup or a (Mexican) Coke, even though its relative percentage of fructose is higher or similar.

No, homemade bread would be NOVA group. 3. The flour itself is group 2 (processed culinary ingredients.) Mixing the group 2 ingredient (flour) with group 1 ingredients (water, yeast, salt) and baking it makes it group 3 (processed food.)

Is the sugar ultra processed?

YeGoblynQueenne 2 days ago

It does make sense if we're talking about yogurt. The sugary yogurts sold at super markets etc don't have sugar sprinkled on top, but mixed in. Normally, you can't do that.

If you make yogurt the standard way [1] and try to add sugar to it while it's still a fluid, it will all sink to the bottom and then you'll just have some yogurt with a layer of sugar on the bottom. If you add it when it's not a fluid anymore, then you'll have a layer at the top. If you try to mix it up in between you'll break it up [2] and end up with mush; with sugar mixed in.

The only way I can think of to add sugar to yogurt and ensure it is evenly mixed throughout its mass is to use some additive, probably some kind of stabiliser. I suspect that's what makes this kind of yogurt qualify for the ultra-processed category.

Check the ingredients on your favourite yogurt. They should say: milk, yogurt culture. End of transmission. If there's anything else in it, then I would say there's a good claim it's been over-processed.

____________

[1] Bring milk to boil or use UHT. Let cool to 45° C (113° F). Add lactic ferments (Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus - readiest source: yogurt). Keep warm. Do not disturb. Wait. Enjoy. Scales up to industrial level (and is dirt cheap to boot).

[2] That's called syneresis - that's when you put a spoon in and then find a little puddle of milky fluid in its wake a few hours later. You've broken apart the jell'0 like structure of the yogurt's curd, i.e. the coagulated milk solids, and caused the milk fluids to leak out.

standardUser 2 days ago

There are many brands of yogurt with "fruit on the bottom" or otherwise unmixed that use plain sugar. Not every store-bought product is the worst possible version of a store-bought product. There's a huge variation.

YeGoblynQueenne 1 day ago

>> Not every store-bought product is the worst possible version of a store-bought product.

I agree with that for the general case but my intuition is that if someone's selling you something ready-made and pre-packaged, that you can easily make yourself (yogurt with fruit mixed in), then that's because they want to charge you extra and force you into a choice -of ingredients- you possibly wouldn't make.

For example, the yogurts with fruit I've had in the UK were just not very good yogurts, and the fruit were just not very good fruit. The yogurts were the thin and tasteless stuff that seems to be typical of anywhere outside the Balkans (I'm Greek) and the fruit were basically preserve, with added sugar. Why do you need added sugar with fruit? Because the fruit is under-ripe and probably too sour to eat in the first place.

You have to think of the economics a bit. Yogurt is cheap to make and most people won't pay a premium for it. Also it's sour and many people (again, outside the Balkans) don't like that. So companies will add sweeteners and sweet admixtures, like jam, honey or fruit to make it more palatable. And of course to make that financially viable they have to drop the quality of the ingredients. And that's where the additives come in: they improve packaging, transport and distribution, even as they degrade taste and nutrition.

Are you sure? Won't the sugar just dissolve into the water that is part of the yogurt? Or if a granule texture remained, just mix in sugar syrup?

I've definitely mixed honey into yogurt and put it in the fridge and it was fine the next day, no separation or anything. Why do you think you'd need a stabilizer?

YeGoblynQueenne 1 day ago

>> Are you sure? Won't the sugar just dissolve into the water that is part of the yogurt? Or if a granule texture remained, just mix in sugar syrup?

Nope. The fluid you're trying to mix the syrup in is milk, already a stable emulsion of proteins, sugars and water. Try mixing sugar (well, corn) syrup in that and see how long it stays mixed in. Once you stop mixing and the mixture comes to rest, the syrup starts sinking to the bottom. Better drink fast, and it sure sets faster than it takes for yogurt to set.

Check out the ingredients on any chocolate milk. There's always a stabiliser, usually a caragenaan. That's to keep the corn syrup and chocolate powder from separating from the milk. Back Home in the Old Country (when I was a kid in Greece) the stores sold a chocolate milk which was just milk with cocoa and some sugar. When you bought it from the store you could see that the milk and solids had separated, and there was a darker layer at the bottom, where all the chocolate and sugar had set. So you had to shake it well before drinking. Nobody makes that anymore, now all the chocolate milks have a stabiliser, so you don't need to expend your precious energy shaking the bottle. All those wasted calories. We don't want that. I guess.

For similar reasons, when you mix honey in your tea you need to keep a spoon in to stir it often, or it all goes to the bottom.

>> I've definitely mixed honey into yogurt and put it in the fridge and it was fine the next day, no separation or anything. Why do you think you'd need a stabilizer?

Because I know yogurt. I basically eat yogurt every day. I even make it myself some times (see my recipe above). Are you sure your yogurt did not have stabilisiers in it?

Honey and agave syrup have oligosaccharides that act as stabilizers. Fructans in agave, specifically.

As does molasses like when making refined sugar. Most unrefined sources of sugar naturally contain chemicals that act as stabilizers because it’s a side effect of many polysaccharides.

ProfessorLayton 1 day ago

Right, but honey and agave syrup can also act as mild adhesives. I'm not sure anyone would consider them an adhesive any more than they would a stabilizer.

YeGoblynQueenne 1 day ago

Also "Greek yogurt" is normally strained so it's already stabilised and is less subject to syneresis.

Note that even with the stabilising effect of straining and honey, real Greek yogurt (the stuff without additives) is never sold with admixtures. Once you mix stuff in you really are changing the consistency of the product and therefore its storage and transportation profile.

There's a scene in Silicon Valley [1] where Elrich Bachman is complaining that people keep taking his narrow spoons that he needs to mix in the jam in the little tub attached to his "Fa-Yeeh yogurt" (spelled "Fage". Surprisingly he pronounces it right! I'm Greek).

Bachman is talking about this product, Fage's split-cup Total yogurts:

https://gr.fage/total-2-split-cup

The reason there's a little tub and you have to tip it in and mix it up after you buy it is exactly because once you've disturbed the yogurt by mixing things in it, you don't have yogurt anymore but a gloopy goo with the consistency of thick cream and that just doesn't travel very well, especially if you want to be exporting your yogurt from Greece (where Fage has its plants) to the US (where Bachman complains about his spoons).

Also that gooey gloop is not what yogurt is supposed to be like. But I suppose that's just a matter of habit.

While I generally agree with the sentiment that we should be cutting added sugar. I have to point out that sugar is naturally occurring in most whole foods. Nearly everything will have at least a little sucrose, glucose, or fructose in it.

Most of the body's natural way of generating energy involves turning macronutrients into glucose and later into ATP. sucrose and fructose just so happen to have very short and very fast routes to conversion.

That fast path is what I think makes sugar particularly problematic (as well as honey and a whole lot of other "natural" sweeteners that are just repackaged *oses). That big jolt of energy which the body ends up converting to fat since it has nothing to do with it is (probably) where most of the problem lay.

Refined sugar is extremely concentrated compared to the natural sources. You need like 50 kilos of sugar cane to produce one kilo of refined sugar, and through multiple steps of heavy industrial processes.

You could make a case for honey, but, like all other natural sources, it contains other ingredients that somehow limits ingestion or metabolization.

Sugar is literally evaporated sugar cane juice. You need a lot of cane to make a little sugar because water is heavy.

Actually carbs are necessary and carbs are sugars. In the past people with diabetes tried to live on a completely carb free diet - but you cannot do that for long. Personally I am not sure I am buying the narrative about fructose - but it is plausible that it might be bad - but glucose you'll have in your blood even if you don't eat any sugar - because your own body produces it if you don't get it from the food directly.

I wonder why nobody has started sweetening stuff with glucose as a 'healthy sweetener'. It is maybe 3 times more expensive than normal sugar - but I guess this is mostly because it is not a common product - cane sugar in Poland is of the same price - and the impact on the price of the end product would be marginal.

For about 10 years, I haven't eaten carbs beyond the VERY rare cookie or two every other month and the insignificant trace amounts in above-ground leafy vegetables and the like. I'm not alone, there are lots of us who eat this way. Whole online communities, full of people who each have their own reasons. I did it for general health and fitness reasons, others do it to reverse their type 2 diabetes.

In the 1960s, a man named Angus Barbieri fasted for over a year under medical supervision and suffered no ill effects afterward. Unless you want to believe the whole thing is a hoax and he was secretly snarfing donuts on the sly, he is proof that humans don't NEED carbs.

The planet used to be dotted with cultures that eat animals and fish primarily or exclusively for hundreds to thousands of years. The Inuit, Mongolian nomads, tribes in the Amazon, etc. They mostly don't exist anymore. (But not because of their diet.)

It's not a big group, but there ARE modern people who live on a carnivore diet for years on end and don't appear to suffer any notable long-term effects. Generally these are either extreme keto/paleo adherents, bodybuilders, or those who are trying to manage a medical condition.

setopt 1 day ago

> Brain needs glucose.

That is actually incorrect, just a common misconception. You might want to read up on ketogenic diets, and specifically the state of ketosis itself.

If you have an ultra-low carb diet (<30 g/day) with only moderate protein consumption (<30% of daily required calories), then the body can’t produce enough glucose to power the brain. Instead, it starts to convert fats to ketones in the liver, and the brain actually runs fine on ketones as well. Alternatively, if you’re not underweight, you can fast for 24 hours with a moderate activity level, and should enter ketosis regardless of diet (as you start converting stored body fat into ketones to power the brain).

Interestingly, you then notice that the “low blood sugar” mental haze disappears as your brain switches over to ketones, and you kinda avoid the rollercoaster between mental highs and lows throughout the day that you usually get with a carb-based diet – instead, mental energy is kinda just at a constant “medium” throughout the day. It’s also easy to measure more objectively, if you pick up a glucose monitoring device + “keto sticks” from a pharmacy.

You seem to be confusing the ketogenic diet with starving. That's not how it works. If you deplete your fat body's stores and get hungry, you simply eat some fat and then your body will burn it for fuel. If you decide to eat much more fat than your body needs, your body will store the fat as fat. But it won't do it quite as readily as with sugar/carbs, and you won't get food cravings mere hours after eating.
