       | confusing health outcomes--a recent observational study from
       | Harvard University, for example, found that whereas some upfs,
       | such as sweetened drinks and processed meats, were associated
       | with a higher risk of heart disease, others, like breakfast
       | cereals, bread and yogurt, were instead linked to lower risks for
       | cardiovascular disease. Dr Astrup warns that the current

       | of upfs, paving the way for more balanced and useful guidelines.

           | 
           | UPFs are defined in a way where you could replace them with
           | essentially identical foods that only count as "processed" by
           | swapping out a couple ingredients with nutritionally
           | identical ingredients (e.g. replace HFCS with sucrose).
           | 
           | The research on UPFs doesn't actually compare ultra-processed
           | food with similar "processed" foods.
           | 
           | So if you replace a pie containing HFCS with a kale salad,
           | yeah it's probably healthier, but there isn't really evidence
           | that replacing an "ultra-processed" pie containing HFCS with
           | a home-made "processed" pie containing sucrose that otherwise
           | has the same nutritional content is healthier (there is some
           | researching showing that fructose can be harmful but the
           | glucose/fructose content of HFCS isn't significantly
           | different from sucrose).
           | 
           | If there is no direct comparison between similar
           | ultraprocessed foods and processed foods, the research
           | doesn't actually show that ultraprocessed foods are bad in a
           | way that homemade processed foods aren't, in which case I'm
           | not sure what the point of defining ultraprocessed foods as a
           | separate category is.

             | 
             | Indeed a lot of people ignore this. Still it is worth
             | pointing out that
             | 
             | a) a higher glucose content due to sucrose based sweetness
             | helps absorbing fructose in a home-made cake.
             | 
             | b) the ultra-processed cake likely got added a fair share
             | of sugar alcohols (keeping it moist) which for a single
             | digit percentage but still significant portion of the
             | population interferes with fructose absorption leading to
             | fermentation in the gut.
             | 
             | c) the longer and cold storage of the industrial cake will
             | lead to an increase of recombined starch which is harder to
             | digest.
             | 
             | (a, b due to fructose transport from gut less efficient
             | than for glucose and the transport part relying on presence
             | of glucose. Some people suffer from fructose mal-absorption
             | where the main transport mechanism is not working and the
             | backup mechanism can be blocked by sugar alcohols)

       | 
       | I've heard drinking juiced fruits is worse for you than eating
       | the equivalent fruits, as the sugars in the fruit are wrapped in
       | fiber that make the sugars "slow release" into your body, and
       | those are broken down when juiced so the sugars hit you at once.
       | I suspect processed foods "mainline" nutrients in ways that
       | unprocessed foods don't.
       | 
       | Secondly, I think a lot micro-nutrition is ignored when comparing
       | processed food, like the fat, carb, salt, etc is equivalent
       | between potato chips and, say, a baked potato with butter, but
       | there are a lot of small things that our body needs that are not
       | part of that equivalence. At least for me, when I eat potato
       | chips I eat more because they never quite satisfy me. I suspect
       | this is because the micro nutrition is cooked or processed away,
       | so I end up eating more carbs because it's not quite giving me
       | all what I need, just the big macro needs.
