I think the older and harder cheeses tend to be lower in lactose if not lactose-free as the process of cheese making and the types of bacteria or mold used removes the lactose. This was the reason cheese became a thing, a hack which allowed our ancestors to take a food meant for other infant mammal species and use it as a food for human adults and another incentive besides wool, leather and meat to learn to domesticate herbivores and move to agriculture.Prefer only lactose-free cheeses. Quite hard to find. Havarti I am told tends to be lactose free. Not sure why it would be (since they all come from cows, and thus dairy).
That and grain for
