For many years, without anything being proven, dairy products have been suspected of being potentially responsible for rhinitis in children, eczema or even wheezing, even though they are rich in micronutrients, fatty acids and probiotics.
In 2012, a study from the University of Cambridge even suggested that yogurt or cream could increase a child’s risk of developing allergies orasthmaasthma. Regarding the latter case, this type of research should not be taken lightly since asthma is one of the most common chronic diseases. While in the United States, it is estimated that it affects 6.6 million children, in France more than 4 million patients are affected, including children and adults. Many risk factorsrisk factors have already been singled out by the scientific community. We talked about smoking as well as exposure to chemicals, or pollution, but also about pollenpollenof stressstress while factors geneticsgenetics would also play a role to take into account.
New study goes against commonly accepted ideas
A brand new study carried out by the Shahid Sadoughi University of Medical Sciences in Yazd, Iran, throws a new wrench into the pond by going against the grain of the role that had been attributed to dairy products in cases of asthma. . According to a study published in Frontiers in nutrition, researchers believe that yogurt, cheese and other creams could reduce the risk of wheezing in children and adolescents. Please note, Iranian scientists clearly mention the benefits of these categories of dairy products, and not milk. The Iranian example is all the more significant since most of the research previously carried out on the association between asthma and dairy products has been carried out in developed countries. However, a report from the International Study on Asthma and Allergies in Children (Isaac) for the years between 1998 and 2004 highlighted the prevalenceprevalence of asthma in Iranian children aged 13 to 14 years. During this period alone, we even noticed an increase from 10.9 to 13.2%.
For their part, Iranian researchers from the Yazd University of Medical Sciences point out that “ Middle Eastern dietary habits have unique characteristics: they contain large amounts of fruits and vegetables, rich sources ofantioxidantsantioxidants and large quantities of carbohydratescarbohydrates refined and harmful fats “. And therefore little or no dairy products. This cross-sectional study involved children aged six and seven but also adolescents aged thirteen and fourteen. In particular, these are the eating habits that were monitored for twelve months.
To understand this potential link between asthma and yogurts and others, scientists point out that “ the activity prebioticprebiotic of dairy products probably results from the stimulationstimulation of the growth of bacteriabacteria beneficial in the intestines, which can modulate the immune responsesimmune responses and thus protect humans from asthma and allergies. THE proteinsproteins milk, in particular lactalbumin, lactoglobulin and immunoglobulinsimmunoglobulinswhey proteins such asalbuminalbumin serum, lactoferrin and lactoperoxidase, as well as various enzymesenzymes And cytokinescytokines present in dairy products would be at the origin of this protective effect “.
The need for further research
However, the authors make it clear that we should not be too hasty in concluding. Impossible to indicate dairy products as protectors against asthma. Not only do other studies need to be carried out to confirm these results, but wheezing is not always caused by asthma but also by other diseases such as refluxreflux gastrogastro-esophageal or persistent bacterial bronchitis.
