  • But the problem is you don’t have anything to tie that to. if you have a car that gets 4 gph but goes 100 mph then it’s more efficient than a car that gets 3 gph but only goes 50mph but even with those you miss out on the actual efficiency which for a car is usually transporting people.

    So if car A gets 4 gph at 100 mph and transports 2 people it gets 50 passenger miles per gallon of gas which is finally an actually useful metric

    For LLMs that becomes much harder to quantify but a useful metric might be wh per minute of time saved or mL of water per minute of time saved. Unfortunately to quantify those you would need to do much more in depth analysis and probably also factor in false readings and time lost from that


  • I am seeing that point and that’s what I am disagreeing with. How is it more useful to have a list of a bunch of things, that some of which are bad rather than just talk about the parts that are bad? A lot of items are flagged as UPF with a negative connotation that are no worse or sometimes even better for you than the level 2-3 items but because of the overly broad classification they are flagged as bad.

    Sure fruit juice is a way to cram a bunch of sugar into a product but so is refined white sugar and yet that’s only a level 2 along with lard.


  • With both mechanically separated meat and the fruit juice concentrate using a vacuum evaporator there should be no difference in nutrition.

    The link to metabolic syndromes and novas class 4 is what I was complaining about because they made the classification overly broad the only people who can fully avoid it are people with extra means or people who but a much more concerted effort into their health and neither of which was controlled. We already know that rich people are generally healthier than poor people so showing that foods that are in general more expensive are “healthier” is just repeating our known values and muddying the waters where it says that simple syrup is a level 2-3 (I don’t remember which and am on mobile) yet throw some ginger into that syrup and now it’s a level 4



  • Their definition is clear but is still arbitrary. Fruit juice concentrate can be made by just reducing down juice yet fruit juice concentrate is considered ultra processed.

    Mechanically separating meat has no effect on its nutrition so why is it a reason to call something “ultra-processed”

    Warming sugar, water, and vanilla beans on the stove is technically considered ultraprocessed by nova

    Using that from a manufacturing standpoint is at least somewhat acceptable but even then foods with much more complex manufacturing are considered processed vs ultraprocessed. However their method of clumping some bad food with such a wide range of products causes foods that are not heavily processed and are benign for your health to be labeled as unhealthy.

    They then never controlled for confounding variables in the meta review study that linked the nova classification of ultraprocessed food to various health conditions.

    This is like saying people sleeping outside 10 nights a year is linked to elevated levels of schizophrenia and never controlling for the difference in people sleeping outside due to homelessness and people sleeping outside for camping. Then the known link between people with schizophrenia being homeless drives the correlation and is strong enough to show elevated levels of schizophrenia amongst everyone who spends at least 10 nights outside

    It’s just bad science and the fact it wasn’t picked up in peer review is just more evidence of how atrocious the whole field of nutrition is. My personal advice is any study that considers the effects of health outcomes without accounting for socioeconomic status or even relative fitness levels is just trash pop science




  • As usual when you see a crazy high percent it’s because they used a very loose definition of “ultra processed”

    “Some of the top sources of calories from ultra-processed foods among youth and adults included:

    Sandwiches, including burgers Sweet bakery products Savory snacks Sweetened beverages “

    After digging into it even deeper and reading the nova classification they used it gets even more arbitrary where they clump a bunch of things into the scary “ultra processed” label for example mechanically separated meat, whey protein, and fruit juice concentrate. But the real kicker and why the number is so high is any food with fructose added to it (not just hfcs) is considered ultra processed

    which by lumping so many things into the one category any person who is able to eat a diet free of ultra processed food is going to have a much higher likelihood of having a higher income, living a lower stress life, and regularly exercising
