SYDNEY --Researchers say consuming lots of soy foods such as tofu and soy milk may improve lung function and lower the risk of developing Chronic Obstructive Pulmonary Disease or COPD. Researchers say the reason could be because soy has anti-inflammatory flavonoids that may protect against tobacco carcinogens for smokers.COPD is described as a progressive decline in lung function. It includes bronchitis and emphysema. Long-term smoking causes almost 90 percent of COPD.
This is the first study to link soy intake to a lower risk for COPD.
