Do I have to exclude all dairy products if I have lactose intolerance?

Most people with lactose intolerance do not need to completely exclude dairy from their diet. In fact, intake of some lactose is advised in order to promote tolerance. Depending on the type and level of tolerance, most people can consume some lactose – typically a daily amount of 12-15 g. A 200 ml glass of milk contains approximately 9-10 g lactose, while the amounts in yogurt and cheese is considerably less, 5.9 g in 125 ml pot of plain whole yogurt and 0.03 g in 25 g of cheddar cheese.
