Kcirla: You may have got a very good point here. I bought goat yogurt & kefir from Whole Foods health store & consumed as it. Maybe it was not fermented enough. They do that to keep it fresh for long I suppose. Next time, I'll ferment (give more time) a little bit more & then consume. I know I badly need yogurt/kefir to build up good culture in my system. I agree with you, probiotic powders/capsules are too weak for this.
Regarding, allergy to spinach & carrot ... I think you are right there too. I have not checked individually if I am allergic to there. May be I'm allergic to only nightshades.
I tried juice diet but didn't stick with it for long & didn't use the right fruits/vegetables. I'm going for that diet after I'm done trying UT.
Again, thanks to you, @Kcirla & @WaterOfLife for your invaluable tips based on your years of experience.
