Broccoli increases the defenses to ward off cancer
This vegetable, rich in antioxidants, may help people suffering from chronic obstructive pulmonary disease.
Obstructive pulmonary disease, COPD, cancer and cardiovascular diseases, a consequence of smoking. Under the theme "breathless not helpless, but" only to celebrate the day of COPD, an event that attempts to prevent this disease worldwide. In this line, say U.S. researchers broccoli is rich in certain substances able to adjust the amount of key components of the system of lung epithelial defense.
Broccoli is classified as a food which benefits the heart and brain, and the high antioxidant content is part of the list of products to assist in the fight against degenerative diseases. The latest study published in the "American Journal of respiratory and Critical Care Medicine" to add a broader curriculum of this vegetable. In addition to heading the list of vegetables anti-cancer, seems to have some substance able to adjust the amount of key components of the system of lung epithelial defense.
Antioxidant and inflammation
Chronic obstructive pulmonary disease (COPD) is the Fifth leading cause of death in our country and, according to estimates by the World Health Organization in 2030 will be the cause of 7.8% of all deaths in the world, exceeded only by cancer and cardiovascular diseases. The snuff is one of the biggest culprits for the development and expansion of this degenerative disease and this is why many surveys aim to find a remedy to decrease its prevalence is increasing.
Researchers at Johns Hopkins Medical School (USA) have found that the severity of COPD in smokers is linked to a decrease in a type of antioxidant present in the lung tissues, dependent on a substance called NRF2, a defense system against key lung inflammations. The link that connects the COPD broccoli and sulforaphane, a powerful antioxidant present in this vegetable in sufficient quantity to avoid, in part, the inflammatory process of damaged tissue in the lung.
This study demonstrates the ability of sulforaphane to restore depleted levels of NRF2 reducing the action of one of its main inhibitor, Keap1. It is also observed both in vitro and in vivo, diseased tissues of the lungs, which improves the level of NRF2 counter other negative effects of snuff. According to Peter Barnes, a member of the National Heart and Lung Institute in London, "therapy directed toward enhancing NRF2-dependent antioxidant might be a novel strategy to mitigate the effects of oxidative stress in the genesis of COPD."
Sulforaphane: a door open to research
Sulforaphane antioxidant was discovered in 1992 by researchers at the Johns Hopkins University School of Medicine and since then has not ceased to investigate their properties. It is classified as a called Glucosinolates which are metabolized in the body and are converted into vegetables, sulphur-containing anticancer and much of the flavor and aroma of cruciferous vegetables like broccoli, cauliflower, kale and Brussels sprouts, among others carrying chemicals plant highly active.
We have studied the action of diets rich in sulforaphane, administered to mice exposed to harmful substances and its relation to lung cancer. According to investigators, the most critical phase in the evolution of this cancer is that in which tumors become malignant. It is precisely this that has been described as "markedly inhibited in rats fed diets with high percentages of sulforaphane.
While the research work on these compounds to achieve the scientific evidence, the manufacturers of dietary supplements and nutritional supplements and pills designed broccoli Extract containing specific doses of Glucosinolates.
