While I’m not an expert, I think most will tell you what one fact I received from Able one of the Moderators and experts on the forum. Kefir is one of the most beneficial forms of Probiotics you can take while on the diet. The Kefir is powerful and can build colonies of beneficial flora in your body. If you can’t eat dairy, I would consider Coconut Kefir. Many believe it’s the most ideal choice.
I just wouldn’t skip the Kefir just because you don’t like dairy. Personally I eat Sauerkraut, Yogurt, Coconut Kefir, Milk Kefir & Pill based Probiotics such as Megaflora. The more strains of good bacteria you can get the better.
