Lactose intolerance

Naturally, as humans age, their lactase level decreases, resulting in relative lactose intolerance, differing individually.

Lactose levels in cheese may differ depending on the conditions of processing and ripening. Lactose levels in Gouda, Edam and Cheddar cheese may vary from insignificant to significant. Cheese produced in one area of England where the manufacturing process is standardised and guaranteed, may have guaranteed lactose levels of below 0.003%.[1]
