Men who ate a healthier diet had a 30 per cent lower chance of experiencing symptoms with a less improved rate of 20 per cent for women.
The foods have antioxidant and antiinflammatory properties and are elements in a healthy diet that potentially lower risks.
Research supports existing evidence that eating well can help prevent the onset of asthma, as well as controlling it.
It also found that men with the condition who have a healthy diet are 60 per cent more likely to avoid severe symptoms. Asthmatic women who eat well were 27 per cent more likely to avoid the worst symptoms.
Lead researcher Dr Roland Andrianasolo, from Paris University, said the research was undertaken because there is a “lack of clear nutritional recommendations for asthma prevention or guidance on how to reduce the symptoms through a healthy diet”.
The study, published in the European Respiratory Journal, analysed data from 34,776 adults. More than half suffered from at least one symptom.
Findings were adjusted in the analysis to consider other factors known to be linked with asthma, such as smoking and exercise.
