Broccoli is good, but research shows just how good it may be for men

Eating just a serving of broccoli per week may be enough to lower your cancer risk, according to new research from the Institute of Food Research.
Their study of 22 senior men suggests that consuming broccoli triggers positive changes in genes associated with prostate cancer. Doctors randomly assigned the men at high risk for prostate cancer to eat either 400 grams of broccoli or 400 grams of peas once per week for one year.

They took tissue samples from the men before, during and after the study to examine genetic changes over time.
Results showed that men on the broccoli diet had greater alterations in genetic activity involved in cell signaling and cell growth -- two pathways linked to cancer risk.
Critics argue that there is no proof yet that the genetic changes lead to lower risk of prostate cancer, so larger and longer studies are needed.
But the government is convinced enough about the health benefits of broccoli and other crunchy, dark green vegetables that they already recommend eating three cups per week.
