I have been getting a jar of whole milk Bulgarian yogurt (don't remember the brand name) from Whole Foods for the past month or so. It has dramatically improved my intestinal health (without any other change in my diet). It has no additives, can be used as starter yogurt and is somewhat tart in taste (which is how real yogurt should taste). Try it. I can't vouch enough for it.
