A new study, carried out by the Archives of Disease in Childhood, has found that the age-old myth that milk is bad for those suffering from Asthma is, in fact, incorrect!
The Myth has been long vocalised, ever since it was started by Jewish Leader Moses Maimonides. The spiritual leader warned those, in his journal for an asthmatic relative of Saladin the Great, that several food types cause the generation of phlegm, thus making asthma symptoms worse.
On his list of damaging foods, he included were fatty foods, peas and beans, foods made from wheat flour, and heavy meats. He warned that cheese, especially older cheese, should be avoided, while milk causes “a stuffing in the head”. He advised that the best way of avoiding these side-effects was to avoid these foods.
According to the results of the study, there is no evidence to suggest that milk consumption leads to worsening respiratory and asthmatic conditions, or excessive mucus secretion.
The study reports that the texture of milk can allude to the feeling of thicker or excess mucus and saliva, thus creating the illusion of worsening asthma symptoms.
Respiratory symptoms as the sole manifestation of food allergy is uncommon.” The study stated.
“Double-blind milk challenges did not cause bronchoconstriction or respiratory symptoms in two studies of non-milk allergic asthmatic adults, including the 50% of subjects who believed that milk worsened their asthma,” it added.
The study also looked into the effect that drinking whole milk, skimmed milk and water had on lung function in 21 subjects, 11 of which had asthma. It was found that following the consumption of milks, that there was zero change to the airflow parameters, though the pulmonary diffusing capacity was progressively lowered by a mean of 21% over three hours in asthmatics who drank full fat milk. Authors could only speculate but suggested that this was due to the effect of milk lipids(fats) on gas exchange.
“While certainly the texture of milk can make some people feel their mucus and saliva is thicker and harder to swallow, there is no evidence (and indeed evidence to the contrary) that milk leads to excessive mucus secretion.” The study advised.
“Milk is an important source of calories, calcium and vitamins for children. The milk–mucus myth needs to be rebutted firmly by healthcare workers.” It concluded.
