The problem with dairy is LACTOSE. For many, if you can find dairy that doesn't have lactose, it is OK - such as the SCD yogurt you mentioned. SCD also allows cheddar cheese (as long as its lactose free) - most of the "Cabot" and "Cracker Barrel" brands are. Basically, the more it is aged, the less lactose it has and easier for people to eat. I've never had a problem with cheese as long as it's lactose free. I actually don't do the SCD yogurt, only because it seems difficult to make. I do buy high-quality, refrigerated probiotics from Whole Foods and similar stores. Ultimate Flora is a good brand that seems to be compatible with SCD.
Best of luck...
