Mythbusters: Does milk cause phlegm?
We have heard this from young-”Don’t drink milk if you have cough or otherwise you will have more phlegm!!!”
Is this actually true or a myth?
Older people believe that drinking milk makes the mucus become thicker, throat become itchier and they feel that they cough more.
As I grew older, I started wondering if this was an old wives’ tale or is there science behind not taking milk when one has a lot of phlegm. Below are the findings backed up with research and science:
- Milk does not result in production of extra mucus or phlegm even when one is sick or has a cold. A 2012 study by the BC Children’s Hospital concludes that no definitive link has been provided between milk and increased mucus production, and that “milk should not be eliminated or restricted.”
- The emulsion texture of milk can make many feel like their saliva has become thicker.
- Milk is an important source of vitamins and minerals like calcium. It helps maintain bone health and prevents bone loss.
- It is recommended to have 2 servings of milk or milk products. If one is lactose intolerant, they can opt for plant-based milk like oat or soy milk.
