> "too much of a good thing" logic.
How many people are having two or three smoothies a day vs. just a single smoothie? How many of those people would eat the amount of fruit in that smoothie over the course of a normal day? There might be something to be said for getting your daily dose of fruit at once instead of spread out over the day, but I doubt that we're talking about people that are overdosing on fruit.
> sugary smoothies and fruit juices
How is a smoothie more sugary than eating the equivalent amount of fruit? Do you claim that someone eating a bowl of strawberries is having a sugary snack?
> That's what makes smoothies particularly dangerous
How dangerous are they really? Plenty of people will drink > 2 litres of soda over the course of a day. On the other hand, do you think that anyone is drinking more than even a litre of smoothie in a day?
> But you just saw them grind up 8 oranges, 5 bananas, and 2 pounds of strawberries and put them in a single cup.
Really? I make smoothies at home, and it's more like: 2 leaves of kale, protein powder, a banana or two, and a handful (or 2) of frozen strawberries (and maybe an apple or pear). This makes enough smoothie for 2 adults and a child. Are you really don't to claim that this isn't something that could be eaten in a sitting by 2 adults and a child?
