Breaking the broccoli code
US researchers claim to have discovered the secret of broccoli's anti-cancer effect
Broccoli has always been a contender for the healthiest vegetable prize. It's packed full of antioxidants and has been linked to lower cancer rates. Now researchers at the University of California believe they have discovered the mechanism that produces broccoli's protective effect.
The team, who reported their findings at the American Association for Cancer Research, found that one of the chemical by-products of the digestion of broccoli, diindolymethane (DIM) reduces the production of proteins needed for ovarian and breast cancer to spread.
"We think these compounds might slow or prevent the metastasis [spread] of breast and ovarian cancer, which would greatly increase the effectiveness of current treatments," said a member of the team.
So far, they have only tested their theory on cancer cells in a laboratory but they are planning animal studies soon. Research is also under way to see whether these chemicals can be developed for the prevention and treatment of breast cancer.
Broccoli has long been known for its health-promoting qualities. Previous studies have found that it can protect against colon cancer and a team from Harvard University in the US found evidence that it could even help minimise the risk of developing cataracts. Ounce for ounce, broccoli contains more vitamin C than an orange and as much calcium as a glass of milk. It is also rich in fibre and vitamin A.
If broccoli is not to your taste you could always try one of the other cruciferous vegetables, such as cauliflower, cabbage and sprouts - all of which have the same cancer-protective benefits.
It is now widely accepted that most cancers are linked to lifestyle factors such as smoking, diet and lack of exercise. A recent study of over 500,000 retired Americans found that just one extra serving of fruit or vegetables a day may reduce the risk of developing head and neck cancer.
