Experts warn, consuming processed meat four times a week could lead to the worsening of asthma symptoms.
A new research conducted in the UK suggests 5.4 million of the people there, afflicted with asthma could be at a greater risk of having their symptoms worsen, if they consume too much processed meat. Scientists deem the nitrites used in the process of making cured meat may lead to the inflammation in the airway tracheas a typical sign of asthma.
Experts from the Paul Brousse Hospital in Paris, monitored the diet and asthma symptoms of 971 people such as their ease of breathing, tightness in the chest and shortness of breath. Amongst them, the ones who ate processed meat as little as once a week, 14 percent of the said demographic had their asthma symptoms worsen over the next four years.
Them, who had been eating processed meat one to four times a week, 20 percent saw their symptoms getting worse and those who ate cured meat four times or more a week, 22 percent of them had their condition worsening.
After taking various influential lifestyle factors such as smoking, exercise and age into consideration, the researchers concluded that those who ate processed meat the most were 76 percent more prone to a worse condition of their asthma affliction.
Being overweight or obese - which has previously been linked to worsening asthma - accounted for just 14 per cent of this association. The calculations showed, suggesting meat intake was independently linked to symptoms.
The scientists, whose work is published in the BMJ journal Thorax, said they could not be sure of the reasons for the link, given their study was merely statistical.
