Higher omega-3 fatty acid intake in childhood was associated with lower risk for incident asthma up to mid-adolescence in children with a fatty acid desaturase polymorphism variant, researchers reported in the

New research suggests that a higher dietary intake of long chain omega-3 fatty acids in childhood may reduce the risk of developing subsequent asthma, but only in children carrying a common gene variant. The study, led by Queen Mary University of London, is in collaboration with the University of Bristol and University of Southampton, UK, and Karolinska Institutet, Sweden.
In the UK, 1.1 million children (1 in 11) are currently receiving treatment for asthma and most adult asthma begins in childhood. The NHS spends around £1 billion a year treating and caring for people with asthma.
Senior author, Professor Seif Shaheen from Queen Mary University of London, said: Asthma is the most common chronic condition in childhood and we currently don t know how to prevent it. It is possible that a poor diet may increase the risk of developing asthma, but until now most studies have taken snap-shots , measuring diet and asthma over a short period of time. Instead, we measured diet
A study published in the
European Respiratory Journal looks at asthma in children and omega-3 dietary intake.
Dr Prasad Nagakumar, Paediatric Respiratory Consultant, Lead for Severe Asthma, Birmingham Women’s and Children’s Hospital NHS Trust, and Honorary Senior Lecturer in the Birmingham Clinic Trials Unit, University of Birmingham, said:
“In a study published in ERJ, Talaei and colleagues using data from two large birth cohorts have shown that in children aged 7 years with a specific variant in FADS gene, high dietary intake of long chain omega 3- fatty acids is associated with 51% reduction in risk of developing asthma at age 11-14. The study population included predominantly Caucasian subjects, mostly not from lower socioeconomic status. Few studies in the past have shown reduction in risk of offspring developing asthma when such dietary modifications are made in pregnant women or in infants. This well-designed study provides valuable data showing that dietar
