My Purple Health Drink

I really loved the color of this drink my web cam didn't do it justice.
It contained pineapple, blueberries and lemon. It was a bit on the tart side but
had a good flavor. The kids all liked it. It seemed to be a bit thick as it sat but
I didn't put any chia or other thickening agents in it so I assume the thickness
was coming from the pulp. There was also no separation between ingredients
as some health drinks do. It may just be the enzymatic action of the pineapple
keeping everything together.
