This is an interesting question – although I am not sure if I can give you a definitive scientific answer.
However, one possibility is that in some people, dairy produce can lead to an increased production of mucus in the upper respiratory and nasal passages.
Although the function of this mucus is to protect the delicate lining of this part of the body, too much mucus can encourage infection and also, lead to blockage of the sinus opening and the Eustachian tube which drains mucus from the middle ear to the back of your throat. The net effect could be a feeling of being ‘bunged up’ or nasal congestion.
I hope that this information is useful to you.
