Is apple cider vinegar paleo?  Do you have any other thoughts on apple cider vinegar?

Hello you-all, I have been raw juicing for about 1.5 years, and it has helped a lot.

I have been doing homemade kefir for about a year.  Although I really like kefir and the idea of kefir and the idea of having my own farm in my kitchen (kefir culturing is farming), and although I haven't experienced the kefir harming me, it doesn't seem to have done as much compared to the raw veggie juicing.

I did a 30 day raw veggie juice fast recently, and at that time I had to decide where to go from there.  Processed foods just didn't cut it anymore taste-wise.  And that is when I started moving towards and studying paleo.  I noticed during the juice fast that fruit juice made me more hungrier.  That was the eye opener that showed me that sugars and carbs were hurting me.  Since I have been more strongly following the paleo diet, I have felt and slept and pooped so much better.  I have even given up the psyllium, which I find completely unnecessary.  Of course early man did not have psyllium.  When looked at from the evolutionary viewpoint, it is absurd to be taking so many pills and powders. 

My questions are, what do you all think of raw veggie juicing [aside from the fact that most raw veggie juicers slide into raw veganism, which is 1/2 wrong (too much for me)]?  I think that raw juicing fits very nicely into a paleo diet, especially given the fact that I am still about 25 pounds overweight (after losing 25 pounds on my 30 day raw juice fast.)

What do you think of homemade kefir?
