Broccoli (Brassica oleracea L. Italica Group) is a vegetable that is included in the cabbage family or Brassicaceae. Broccoli comes from the Mediterranean and has been cultivated since ancient Greek times. These vegetables into Indonesia recently (around 1970) and is now quite popular as a food ingredient.
The edible parts of broccoli is green flower heads are compact like a tree branch with a thick stem. Most of the flower heads surrounded by foliage. Most similar to broccoli cauliflower, but broccoli is green, while the white cauliflower.
Broccoli is a plant that lives in cold weather.
As a food, usually boiled or steamed broccoli, or can be eaten raw. Broccoli contains vitamin C and dietary fiber in large quantities. Broccoli also contains compounds glukorafanin, which is a natural form of anticancer compounds sulforafana (sulforaphane). In addition, broccoli contains isothiocyanate compounds, as sulforafana, suspected to have anticancer activity.
The benefits of broccoli for breast cancer
Although it has been known to consume certain vegetables, such as broccoli, can help prevent breast cancer, but the mechanism is not known active part in the vegetables that hinder the spread of cells.
Some scientists at the University of California, Santa Barbara, reported their new research has shown that vegetables like energy healing works at the cellular level in Washington, Tuesday (23/12). The results of the study published in the journal Carcinogenesis, published in December.
"People can protect themselves from breast cancer by eating vegetables that can be eaten like cabbage and immediate family such as broccoli and cauliflower," said lead study author Olga Azarenko.
"These vegetables contain compounds called isothiocyanates which we believe to be responsible for the activities of anti-carcinogenik and-cancer prevention in these vegetables," he said.
Their research focused on the anti-cancer activity in one of these compounds, called "sulforaphane", or SFN.
It has been shown reduce the occurrence and rate of breast tumors caused by chemicals in animals. These substances inhibit the growth of breast cancer cells in humans, resulting in cell death.
The researchers made a surprising finding, SFN prevent the spread of human tumor cells by a mechanism similar to the way anti-cancer drugs "taxol" and "vincristine" blocking cell division submarine "mitosis" is the process of division of the genome has been duplicated by the cell into two identical cells produced by cell division.
However SFN is much weaker compared with other drugs based on plants, so not too much is toxic.
"SFN may be an effective cancer preventive agent because SFN blocking proliferation and kills precancerous cells," said the study's authors.
The materials may also be used as an adjunct to "taxol" and other similar drugs to increase effective killing of tumor cells without increased toxicity.
