Is it healthy to drink a green smoothie everyday?
If its a smoothie with all of the bad sugars and fats then no. If its green drinks such as as one you make yourself with lettuce and frozen fruits then yes.
If the contents of the smoothie are healthy, then yes.
Yes, they have too much sugar. Unless it's low on calories and doesn't have that much sugar then it's not that bad.
Yes. I used to drink a whole blender of green smoothie in a day
