If you have asthma, switching to a healthy diet of fruits, vegetables and whole grain cereals may help in reducing the symptoms like difficulty in breathing, chest pain and coughing among many other things, according to a study.

On the other hand, those who take unhealthy diets, with high consumption of meat, salt and sugar, are likely to have the poorest relief from asthma symptoms, the study showed, suggesting the role of healthy diet in preventing the onset of asthma as well as controlling problem in adults.

“A healthy diet is mostly made up of a high intake of fruit, vegetables and fibre. These have antioxidant and anti-inflammatory properties and are elements in a healthy diet that potentially lower symptoms,” said lead researcher Roland Andrianasolo, from University of Paris 13 in France.

“In contrast, the least healthy diets include high consumption of meat, salt, and sugar, and these are elements with pro-inflammatory capacities that may potentially worsen symptoms of asthma,” he added.

The results also showed that for men and women with asthma who adhered to healthy diets, the likelihood of poorly controlled symptoms was lower by 60 per cent and 27 per cent respectively.

For the study, published in European Respiratory Journal, the team analysed data from 34,776 adults.

Overall, men who ate a healthier diet showed a 30 per cent lower chance of experiencing asthma symptoms, while in women with healthier diets, the chance of experiencing the symptoms was 20 per cent lower.

“Healthcare professionals must find the time to discuss diet with their patients, as this research suggests it could play an important role in preventing asthma,” the researchers noted. (IANS)

Flavoured E-Cigarettes Affect Airways, Worsen Asthma

Certain flavoured e-cigarettes, even without nicotine, may change how airways, affected by an allergic disease, function, thus worsening the severity of asthma

Certain flavoured e-cigarettes, even without nicotine, may change how airways, affected by an allergic disease, function, thus worsening the severity of diseases such as asthma, say researchers.

For the first time, a model of asthma was used to investigate the effect of a range of popular e-cigarette flavours, with and without nicotine.

“This is especially important for those with respiratory disease, whom are vulnerable to the effects of smoking,” Dr Chapman said.

“The majority of e-cigarette smokers use flavoured liquids but there is some evidence that flavour additives can be toxic when inhaled,” said Dr David Chapman from from the University of Technology Sydney (UTS).

The use of e-cigarettes has dramatically increased in the past few years, especially among younger smokers globally.

Despite the suggestion they are a healthier alternative to tobacco cigarettes, there is a lack of evidence in both animal studies and human data on the effect of e-cigarettes on lung function.

The researchers found that some flavoured e-cigarettes, even in the absence of nicotine, can worsen disease severity.

“The exact effects on features of asthma were dependent upon the specific flavour, suggesting not all flavoured e-cigarettes will have the same consequences on lung health,” Dr Chapman said in the study published in Scientific Reports.

In this study, the flavour Black Licorice exaggerated airway inflammation whereas Cinnacide had the opposite effect, suppressing airway inflammation.

The researchers didn’t analyse the liquids directly, to confirm what they contained, however there is evidence from previous research that flavours categorised as “buttery/creamy” and “cinnamon”, which likely include “Banana Pudding” and “Cinnacide”, respectively, are toxic.

Caution should be taken in promoting the use of flavoured e-cigarettes to patients with respiratory disease such as asthma and that policy makers should consider restricting the use of flavoured e-cigarettes, the team added. (IANS)
