You don't want anything except what you squeeze yourself.

Anything you buy squeezed has been pasturized.
It kills the enzymes which your body will need.

I always find juicing oranges which work good.

Don't eat them until you have finished with the juice stage.

This juice stage is designed to gently transition your shutdown digestive system over to being able to handle more foodlike items.

Don't overdo it when you get to these stages.
