A study by researchers from the University of Seville found that high concentrations of fine particles (PM2.5) in urban areas increase hospital admissions for children with respiratory illnesses such as bronchiolitis, pneumonia, asthma, and bronchitis. Reducing PM2.5 levels to the recommended WHO threshold could lead to a daily saving ...
A randomized trial of nearly 400 children and adults with poorly controlled asthma found that supplementation with soy isoflavone did not improve lung function or clinical outcomes. The study suggests that this supplement should not be used for patients with poorly controlled asthma.
A new study from Northwestern University finds that soy supplements do not improve lung function for patients with asthma. Lifestyle and diet may play a role in managing the disease, rather than relying on individual strategies like increasing soy consumption.
