Broccoli protects against lung disease

Substance in broccoli can reduce the damage in the lungs, leading to the development of chronic obstructive pulmonary disease (COPD). The cause of this disease is smoking in general. COPD claims the lives of many smokers each year, reports the BBC. American scientists have discovered that a substance that improves sulforapane NRF2 gene in human lung cells. This gene protects cells against damage caused by exposure to toxins. The study was published in the American Journal of Respiratory and Critical Care Medicine. NRF2 gene activity in smokers with COPD significantly reduced. According to researchers, this gene is removed for the involvement of multiple mechanisms, toxins and other harmful cells from the body. The results showed that broccoli contains a natural ingredient that normalizes gene NRF2. According to experts, this vegetable is used to treat chronic obstructive pulmonary disease, but this needs further research. While the experiment was conducted only in mice in the laboratory, the researchers reported.
