What does… actually mean?
There are people who suffer from an intolerance to milk and dairy products. The reason for this is the lactose contained in milk. This intolerance varies greatly among sufferers. As a result, even the consumption of small amounts of lactose leads to problems with some people, while others can tolerate it to a very reasonable extent. It is only in the rarest of cases that you have to refrain completely from consuming dairy products. It is important to know your personal tolerance threshold to be able to enjoy dairy products as an important supplier of calcium.
