Soy supplements does not improve lung function for patients with asthma, says a new study which is contrary to previous findings suggesting a link between soy intake and decreased asthma severity.
The study highlights the importance of focusing on overall health to manage disease, rather than individual strategies such as increasing soy consumption.
Asthma
It''s a lung condition characterized by inflammation of the bronchi and constriction of the airways that result in coughing, wheezing or breathlessness. Allergy and other airway irritants can trigger it

Indian-American researcher Ravi Kalhan, associate professor in medicine-pulmonary and preventive medicine at Feinberg also contributed to the study.

Doctors at the Indian college say that asthma-chronic obstructive pulmonary disease is a newly-identified problem found among asthma patients who are smokers.
The study explored the effects of soy in 386 adults and children aged 12 or older with poorly controlled asthma. All were taking medicine to treat their asthma but none were consuming soy.
In the randomized study, half of the participants took a soy isoflavone supplement twice daily for six months, and the other half took a placebo.
"We found that the supplement, though able to increase blood levels of the key soy isoflavone genistein, did not improve lung function, symptoms or measures of inflammation in these individuals," Smith said.
"This study highlights why it is so important to perform well-designed, placebo-controlled studies when associations are reported between specific nutrients and disease outcomes," Smith said.
The study appeared in the Journal of the American Medical Association (JAMA).
