What about almond milk?
Is it ok to drink, or not?
It IS ok to drink! Make sure you use unsweetened almond milk. 1 cup is 1 serving in C3.
As for it being a probiotic replacement, it does NOT have any probiotics in it.
Personally, because of the lack of probiotics in it, when/if I drink it, I just consider it an added food item and I don't go overboard using it. I would recommend 1 or 2 cups maximum per day -- but as with everything, this diet is about choices and making this work for us, so less or more is really up to you.
