This is why juicing is bad, specially if you consume it too quickly. Smoothies are better but eating whole fruit and vegetables is the best.

  Is there a difference if you're blending whole pieces of fruit and veg, so you get pulp and all?
  • jshmrsn 5y ago
    That’s probably what he means by smoothie. Though I’m sure some “smoothies” are fruit juice with blended ice.

    Yes, somewhat counter-intuitively, because chewing essentially turns fruit into a smoothie! The difference is the chewing effort and the time taken. Eating more than two apples makes me tired even thinking about it. I never eat more than one at a time in practice. Similarly with carrots, I'll happily crunch through maybe half of a large carrot, but never a whole one. Meanwhile, most people can just gulp down four to six apples or carrots worth of juice -- pulp and all -- without feeling immediately satiated. That's the difference: in juice form we can happily ingest far more food than we would prefer to eat via normal chewing. Note that it's entirely possible to eat the same amount of apples! It's just exhausting and even unpleasant.

I wish people would apply this logic to things like olive oil where a tablespoon contains about 20 pressed olives and about 120 calories. It's one of the easiest way to eat hundreds of extra calories more than you should and lots of recipes suggest using a lot of it for frying and dressings. I think the common encouragement of "but you need fat, it's healthy fat and it's part of the Mediterranean Diet!" is a weird dietary blindspot when the goal is calorie reduction and fat deficiencies aren't the problem. It feel like it's only quite recently that fruit juices are being discouraged and that was a blindspot too. I don't advocate that there's some magic to a "whole food" diet except that not eating pressed, blended etc. stuff is a decent rule of thumb to slowing down much you can eat in one sitting.

        Olives are delicious, and I can eat twenty in seconds…
        • seanwilson 5y ago
          Would you eat sixty olives plus a meal though? I see celebrity chefs free pouring way more than a tablespoon per serving in recipes all the time.
          • ip26 5y ago
            Aside from pesto I don’t use more than a Tbsp per serving- I suppose I am out of touch with celebrity chef cooking.

            Most of it ends up in the pan and plate, though

        There was an experiment conducted with three groups of rats. The first got only fed carbohydrates and gained weight. The second ate only protein and lost weight. The third ate fat exclusively, their weight stayed the same.

          [citation needed] Sorry, I don't mean to be snarky, but you can't just make baseless claims and expect others to believe them. It's far easier to make claims than to verify them so there's a significant asymmetry at play here.

            Yeah, you are absolutely correct. Sadly i don't have a link at hand :(

      Also, chewing and saliva (specifically the enzyme, amylase) combine to start breaking down more complex fibers and sugars before they reach the absorptive parts of the tract.

        should people start spitting into their smoothies before drinking them?
        • _nalply 5y ago
          Thought-provoking, but maybe yes. Put about half a dozen spoons of spit into the smoothie, then stir and leave for ten minutes.
    • wodenokoto 5y ago
      You end up comparing whole fruits to “juice form”. I’m not sure if that’s a typo, as the question is related to the difference between whole fruits and smoothies, and that’s also how your argument starts out.

      Chewing also elicits the release of enzymes in the mouth and gut and also starts a hormonal cascade that prepares the digestive track to process the food. https://www.yourhormones.info/hormones/gastrin/ https://www.yourhormones.info/hormones/gastrin/ https://www.gastrojournal.org/article/S0016-5085(04)01993-6/fulltext https://www.gastrojournal.org/article/S0016-5085(04)01993-6/...
