smoothies

They are way better than any soft drink. Even if you pick the fruit with the most fructose/glucose percentage you still get the benefit of slower digestion due to fibers which slow digestion. Slight exaggeration, but in comparison, drinks are almost an injection of sugar into the blood-stream.

I would consider them healthy if they are ingested in appropriate quantities, without any added sugars, and along with some additional food that is rich with protein and fibers, like wheat and grains.
