Smoothies were mentioned on my diabetes prevention course. Fruit smoothies break down the fibre and release the natural sugars of the fruit so that the sugars in them are absorbed almost immediately into the blood stream and sugar =sugar, so getting all that sugar into you allat once is not good, same with juice, when I was younger fruit juice was drunk in small amounts and not often. Non starchy veg in smoothies - ok, quite a wake up call that seemingly healthy drinks are actually not that good for you in uantity and often. Lookat how smoothie manufactures boast about how many items of fruit there are in a bottle of their smoothie. I learned that of your 5 a day 3 should be veg, portions the size of a couple of handfuls, only 2 of fruit, of which the portion size should be only one handful. So getting a large amount of liuidised fruit in one is actually really bad for your health as it is like eating the euivalent amount of a sugary drink, albe it with some fibre and vitamins and minerals included
I was gutted to learn abuot juice and smoothies but my blook sugar levels have gone down to non dangerous levels a voiding them [and obviously other stuff]
This is all NHS guidance based, the courses are ru on behalf of the NHs
Smoothies with yoghurt in better as they contain protein which helps slow down the absorption of sugar, if the fruit is just a flavouring for vegetable juice
As for don't teeth break the fruits down, well yes but to a lesser extent. But how long would it take to chew all that fruit to a liquid consistency, like a blender does, with blades. We'd be like Mr Gladstone who said "I have made it a rule to give every tooth of mine a chance, and when I eat, to chew every bite thirty-two times. To this rule I owe much of my success in life."
How long would that take compared to how long it takes to drink a glass of a smoothie or juice
And Marketing - contains no added sugar, well true but it doesn't need added sugar with all that sugar already there
