We ask experts to clarify if drinking milk really leads to increased mucous production

Further, pointing out that Indian patients with chest diseases have a lot of “fixation with phlegm”, Dr Arjun Khanna, HOD, pulmonary medicine, Amrita Hospital Faridabad said: “A lot of foods like banana, rice, milk are associated with phlegm production. But modern-day medicine does not support the association of food with phlegm production.”

A study published in the Journal of the American College of Nutrition also found no significant difference in the mucous production of participants who drank cow’s milk compared to those who consumed a soy-based drink.

“Some may experience symptoms like increased phlegm or mucous after consuming milk because of personal sensitivity or mild intolerance to dairy products including milk. This is not the same as a generalised increase in mucous production for all. Those with respiratory conditions such as asthma or bronchitis may worsen their symptoms due to the thick feeling milk leaves in the throat, but it does not cause an actual increase in mucous production,” said Reshma.

If you have phlegm with associated respiratory disorders, Dr Khanna said suggested taking medications regularly. “Use a face mask while going out, consume a lot of fluids, and keep yourself hydrated,” the expert said.

For the vast majority of people, drinking milk does not exacerbate respiratory conditions or lead to a noticeable increase in mucous production as supported by scientific evidence. “For those who enjoy milk and dairy products, there is no need to avoid them out of concern for mucous production,” said Reshma.

Dr Khanna also added that if the phlegm is yellow or foul smelling, “it signifies chest infection and should be seen by a pulmonologist immediately”.
