  • Sure, the person eating it can probably tell. But often that information isn’t collected in the survey being used in a study. Standardized questionnaires don’t necessarily capture this information. Some of these studies are built on old datasets because they are looking for long term affects. Sometimes all you have is ‘burger’, or ‘chicken soup’. Sometimes you have even less than that. Sometimes all you have are the answers to questions like, “In the past six months, how many times per week did you eat red or processed meat?”.

    Now, sure, some studies are based on surveys that collect information about the level of processing, but these have issues too, ranging from moving the interpretation of what processed is over to the subjects of the study, to protocols that include verbose food diaries that no participant could be expected to adhere to for long.


  • These are simple words used to broadly define categories of foods with the assumption that people understand they’re not going to list out every fast food and restaurant burger in the United States sorted by calories and ultra processed ingredients.

    Yes, and these are the words that most likely appear in the retrospective survey results on which these studies are undoubtedly based. My point was that equating a set of words that describe end products (like ‘burgers’, or ‘chicken soup’) with a set of words that describe preparation (‘ultra processed’, or ‘minimally processed’) is not at all straightforward. Any word (or at least many) in one set could be mapped to almost any in the second set. I just chose ‘burger’ out of convenience. If you told me you had chicken soup for lunch, could I automatically know if it was ultra processed or not? Would a researcher know?


  • Again, though, burgers vary. Yesterday, mine included sliced red onion, arugula, and a slice of swiss. No ketchup, no mustard, etc. I did put dab of olive oil based herb sauce (that I had made prior to this) on it. Yes, I’d say that the bread was by far the most processed part of the meal. I’m just not convinced that this burger was worlds away from a steak and a side salad.

    I know not all burgers are the same, but that is the point isn’t it? I found my meal hyperpalatable, but should it be considered ultra processed? If it should, then how should we distinguish it in discussion from even more processed versions? I don’t have an easy answer for this.


  • Agreed. Early on, the article points to burgers as a main culprit. I just happened to make myself a burger yesterday. Other than coarsely grinding the cut of beef (chuck), what was so ultra processed here? Was the beef so very different than the steak I could have made instead? I would imagine that the authors had envisioned a more heavily processed, meat from a tube sort of burger than mine, but that’s the problem with communicating information like this. The imprecision of the language is killing the messaging and undermining the research.
