There is a lot of stuff I can't eat because the amount of added sugar is disgusting.

Yeah, but even a cup of celery contains a gram of sugar. Eating "no" sugar is preposterous. You could never eat any fruits or vegetables! But lots of people avoid excess sugar, me included.

> Eating "no" sugar is preposterous.

This is relatively easy for anyone on a carnivore diet.

Can you please give your reference for that definitive statement. And what are 'nutritional studies'? Why wouldn't they include the research that led to the list of nutrient recommendations issued by USDA and similar publications in the UK, Norway, France, Australia and many other countries. No conclusions from them? I think there are. There is a truly vast literature on subjects nutritional so it's vital to be very…

The RDA and nutrient recommendations are the bare minimum so you do not die. Vast literature is ad populum fallacy. Also consider that genetic background matters in nutritional matters and well... The populations under study have changed, and that's assuming you have a fairly similar background to a population and not very mixed. And we are not even getting into how these things go down in practice, with heavy indust…

They are not, they are recommended averages.

RDA for vitamin C is 60mg, but you can survive without getting sick on 5-15.

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, the…

This is an incredibly bizarre comment - I buy unsweetened yogurt and sometimes mix honey in before I eat it.

My comment is about adding sugar to yogurt during production. Please read more carefully (e.g. the part of the comment that explains how it's made and why sugar can't be added at that moment).

the root cause, at least for bread, is pretty simple; US supermarket bread has a lot more sugar than freshly baked bread, because sugar is a preservative.

most definitely not. sugar doesn’t even make top-10 list

Subway "bread" had too much sugar to be classified as a bread in Ireland

I don't meet smokers arguing smoking isn't actually bad though...

I haven't met one that argued it isn't bad, but many have certainly downplayed it, or they have wildly different standards. Like...15 years ago, I dated a girl that smoked, but wouldn't eat anything with artificial Blue or Red color because supposedly those cause cancer. I said, "You know those cigarettes cause cancer, right?" and got met with a "yeah whatever". That relationship didn't last (for many reasons), and I…

My mom switched from Diet Coke to full sugar Coke because she heard that Diet Coke causes cancer. All while being a pack a day smoker. It’s crazy out there.

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.

>> 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, t…

I think you're ignoring the hundreds of higher-end brands that are trying to appeal to people like us. Some are still shit, some are, by all possible accounts, actually amazing.

It's actually not hard to eat a diet that doesn't have a lot of fructose. More difficult to avoid heavily processed carbohydrates that are absorbed too quickly.

Seems like the cited studies confirm things we already know: when humans are given tasty high caloric-density foods, they consume more calories than when not given those foods. I didn't see a cited study showing that these ultra-processed foods led to worse outcomes when caloric intake was held constant. Did I miss something?

I haven't read the article, but research has identified several components of processed foods that are detrimental to health beyond their caloric content. *Trans fats*, often found in hydrogenated oils, raise bad cholesterol levels and are linked to heart disease and diabetes[3]. *Added sugars* and high fructose corn syrup, prevalent in many processed foods, increase the risk of obesity, diabetes, and heart disease[1][3]. *Sodium* is another common additive that can lead to hypertension and cardiovascular issues[1][3]. Additionally, *refined carbohydrates* cause rapid blood sugar spikes, contributing to metabolic disorders[3]. These components collectively contribute to chronic health conditions and increased mortality risk[2][4].

Socially acceptable eating disorders are the foundation of multiple hundred billion dollar companies. Every junk and fast food company in America sells food that does not satisfy you, is unhealthy for you, has a "taste" that is not easy to replicate at home but that has been scientifically curated to prevent you from reaching the satiation point when you are eating them (like Pringles, "Bet you can't eat just one", b…

It’s both. I do recognize, and agree with most of what you’re saying. The junk food industrial complex is real. But people have autonomy and if you took their burgers away tomorrow they’d riot. > It's not an eating disorder to eat junk food in America. It absolutely is a disorder to eat to the level you described in your previous comment. Just because millions of people take part in it, and it’s socially acceptable d…

So you're saying ordering any food from a fast food restaurant is an eating disorder?

The average combo meal clocks in at nearly a thousand calories at a minimum at essentially every fast food restaurant in America even if you just drink water with it.

I get where you're coming from, but it is entirely too easy to not see the bigger picture and to blame the victims of the system. The system is fucked, it is fucked on purpose because that is profitable, most people are too stupid too ignorant or at least two uninformed to know about it and even more so do anything about it.

Blaming overweight Americans for their overweightness just lets you personally feel better about yourself while doing nothing to actually identify or solve the problem.

Ah yes, the ol' I can't tell a fruit farm from a factory shtick

Ah yes, the old completely ignore the question shtick. And yeah, most fruit around me went through various inspection, sorting, washing, labeling, packaging, and potentially even cold storage places that are in big buildings with loads of trucks moving pallets of materials around with loads of automated machines. All things that seem very "factory". What is the final delineation where it goes from some guy in his bac…

My guidance was: "If it couldn't be made outside a factory, it's ultra processed."

An apple can be made outside a factory. A steak can be made outside a factory. That doesn't mean there aren't factory farms.

Sugar cannot be made outside a factory. If you press and boil your own sugar cane, you won't get refined white sugar.

The candied bacon you buy at the store could not be made at home. The sulfates and industrial products alone would be impossible to make.

If you made your own, that'd be way healthier.
