Steve, I wish you were correct about lactose intolerance but you are not. Cheese has to be aged or otherwise treated [smoked, for example] to allow the lactose to be gone. My life has changed significantly since I have learned which cheeses will make life unpleasant for me. Yogurt acts as a probiotic if it has active cultures to digest the lactose for me. It has become a relatively minor affliction for me.

Lady Hillary's form of intolerance is more of an allergy to unaged cheeses. We are both still experimenting to find out what to enjoy and what to avoid and will probably do so for the rest of our lives. For some reason, a good brie is safe for me.
