Original title: Japan's university experiments proved that soybean isoflavones can prevent chronic obstructive pulmonary disease
According to the Asah Shimbun website, the research team at Osaka City University in Japan, through experiments in mice, determined that isoflavones contained in soybeans have a preventive effect on chronic obstructive pulmonary disease (COPD) such as emphysema and chronic bronchitis. The project's findings were published on August 29th in the electronic edition of the scientific journal Nature.
COPD is a disease that causes symptoms such as wheezing and difficulty breathing, mainly due to cigarette smoke. According to the World Health Organization (WHO), COPD ranked third in the world in causes of death in 2016, with an estimated 5 million COPD patients in Japan. Although experiments have determined that people who consume large quantities of soy products have a tendency not to develop COPD, the specific reasons are not yet clear.
team conducted a 12-week experiment in which mice "smoked" for one hour a day, depending on the observed difference between "smoking" and isoflavones. The experiment divided mice into "smoking" and "non-smoking" groups. The results showed that the "smoking" group was more likely to gain weight than the "non-smoking" group. Moreover, in "non-smoking" mice, the group that added 0.6% isoflavones to the bait was more likely to suppress bronchitis and albeum inflammation and the development of emphysema in the body than the group that did not add isoflavones."
is the first to prevent COPD from quitting smoking, but this trial has shown that soy isoflavones can inhibit the development of emphysema in the body, " said Professor Edi Edi, who majors in respiratory medicine at the university. Therefore, soy isoflavones can be used to inhibit the incidence and development of emphysema treatment. "
