The colds of our sons and daughters can put their hands to our heads. When children, especially the youngest ones because they have a weaker and less developed immune system, seem to have finished that cold, a week later they come back with coughing and coughing. snot.

The latter are of great concern to parents about the congestion and the breathing difficulties they cause. Around of the mucus There are many myths, and one of them is related to the milk consumption. Have we ever heard that drinking milk when a person has a cold increases the amount of mucus? It is an idea that is still valid in our society. Is it true that milk intake increases mucus or is it a myth that has been dragging on for a long time? Science answers.

Scientific evidence on the relationship between cow’s milk and mucus

The study of the relationship between milk and the increase in mucus during a cold has been the subject of attention since the 12th century. The Jewish doctor Moses Maimonides wrote in his “Treatise on Asthma” that some products caused an overproduction of phlegm in people, including dairy foods.

Since then, this idea has reached our days, and science has wanted to refute or affirm this relationship between dairy and mucus. Most of the scientific evidence indicates that we are facing a myth: no relationship between cow’s milk intake and increased mucus.

In 1990, A study published in the American Review of Respiratory Disease carried out the test to verify this relationship. A group of volunteers were given the common cold virus and urged to drink cow’s milk. This research showed that its consumption does not increase the symptoms of a runny nose, although they did appreciate that the significant increase in cow’s milk intake reduced people’s coughs.

Other studies, such as It is published in the Journal of the American College of Nutrition, which reviews the research done on this relationship, notes that people who believe that milk increases their mucus when they have colds tend to self-report a greater sensation of mucus. But the results of the studies show that truly the level of mucus in both the consumption of cow’s milk and lactose-free milk is the same. The sensation they have may be related to the mixture of the texture and the emulsion of the milk together with the saliva that can generate the sensation of more mucus.

However, in 2018 it was published in the journal Laryngoscope the first study which contradicts the above. A group of people with rhinitis (inflammation leading to severe stuffiness and stuffiness and sneezing) were given a dairy (cow’s milk) and a lactose-free diet, and the lactose-free diet was shown to significantly reduce nasal discharge in 4 days. On the contrary, with the lactose diet the mucus increased from the first day and from the fourth to the seventh day there was a large increase in nasal discharge.

As this is the first study to claim that intake of cow’s milk increases snot, new clinical trials are needed to prove this relationship.

For these reasons, most studies indicate that dairy should not be withdrawn from the diet of both children and adults when there is a cold. If its withdrawal must be taken into account if the person has any allergies or lactose intolerance.

Respiratory effects of milk consumption in asthmatic children

In the previous study cited from the Journal of the American College of Nutrition they point out that the consumption of milk does not increase the symptoms and the repercussions that asthma has in people.

Other investigation of 2020 published in the journal BMC Pediatrics also states this. In the clinical trial, cow’s milk and soy milk were given to asthmatic children and others without asthma to measure whether dairy could make breathing or mucus worse. This study again showed that the intake of cow’s milk in both asthmatic children and children without asthma does not produce either increased nasal discharge or bronchial inflammation.
