Just curious.

Think it's allowed during the full liquid phase....

I hope so as I have been having them everyday. LOL My doctor said they were considered liquids.

Yeah they are allowed, just make sure that your fruit is real fruit and not concentrated. I recently had a bout with a smoothie; I had order from a smoothie restaurant. The fruit was concentrated syrup with most likely contain added sugar. Boy, I quickly learn what happens why you eat sugar. So make sure your smoothies is made from real fruit.

Be careful of the seeds in the fruit. The seeds could get stuck in your staple line.
