People who eat lots of soy products have better lung function and are less likely to develop the smoking-associated lung disease COPD (Chronic Obstructive Pulmonary Disease). A new study has shown that consumption of a wide variety of soy products can be associated with a reduction in the risk of COPD and other respiratory symptoms. Dr. Fumi Hirayama and Professor Andy Lee from Curtin University of Technology, Australia, worked with a team of respiratory physicians to poll 300 patients with COPD from six Japanese hospitals and 340 age-matched control subjects from the same areas as the patient ...

Consuming lots of soy foods such as tofu and soy milk may improve lung function and lower the chances of developing chronic obstructive pulmonary disease (COPD), new research suggests. Researchers asked 300 COPD patients in Japan and 340 age-matched healthy people about their soy intake. The results, published online in the journal Respiratory Research, indicate that consumption of soy products is associated with better lung function and reduced risk of COPD. Long-term smoking causes 90 percent of cases of COPD, which is characterized by a progressive decline in lung function and includes chr ... Jump to full article >>
