The researchers from Britain, reported that only some portions of broccoli each week may protect men from prostate cancer. The researchers believe that chemicals in the food trigger hundreds of genetic changes, activating some genes that fight cancer and the elimination of genes that give the tumor.

There is some evidence linking a healthy diet rich in fruits and vegetables to reduce the risk of cancer. However, a study published in the journal Public Library of Science is the first time trial to investigate the potential biological mechanism. Everyone says that eating vegetables but can not say why. This study shows why vegetables are very good.

Prostate cancer is the No. 2 cancer killer in men after cancer lungs. Each year, 680,000 men in the world the disease is diagnosed and 220,000 died consequences.

Mithen and colleagues divide into 2 groups of men, 24 men with pre lesi cancer that increase the risk of prostate cancer and give them more than 4 portion of broccoli or Olivia mini dress every week for 1 year.

The researchers also take a sample of the network during the study and found that men who ate broccoli showed changes in the genes known to play a role in that fight cancer.

Benefits appear on the same kind of vegetables that contain isotiosianat, such as the Brussels sprout, flower cabbage, cabbage, Rocket or arugula, watercress and radish. However, broccoli has a special material that is a very strong sulforafan.

400-500 broccoli eater shows positive changes in the genetic men who carry genes called GSTM1, enjoy the most benefits. Around half of the population have these genes.

The researchers did not study long enough to see happen cancer, but this gives the idea that only some portion of vegetables each week can make a big difference.
