Is milk beneficial when you're sick? The doctor provided a clear answer.

According to Dr. Julie Bonn, drinking milk during a cold will not lead to the production of mucus. Yes, mucus naturally thickens during respiratory infections, but this occurs regardless of milk consumption.

A 2019 study published in the National Library of Medicine found that some individuals may experience increased mucus production after consuming dairy products. However, earlier studies did not find such a connection in healthy individuals or those suffering from respiratory infections.

Overall, existing data do not support the idea of avoiding milk during respiratory infections, unless you have a diagnosed sensitivity to dairy products or lactose intolerance.

Moreover, the doctor suggests that milk can actually be beneficial for people with a cold or sore throat. It soothes irritated throat tissues and contains essential nutrients.
