Cauliflower

Cauliflower contains indoles and sulforaphane - both anti-cancer elements.

Carrots

1. Carrots are high in caretenoids which fight a whole range of cancers.

2. They contain lutein and zeaxanthin which help protect eyes and help to prevent macular degeneration and cataracts.

3. To get the most out of caretonoids in carrots, eat them with a little fat, as caretonoids are fat-soluble nutrients and are better absorbed that way.

Cabbage

1. Cabbage contains Indole-3-carbinol, which helps fight cancer.

2. Other cancer-fighting elements include dithiolethoiones, isothiocynates and sulforaphane.

Brussel Sprouts

Brussel sprouts contain sinigrin which suppresses the development of pre-cancerous cells. They are also high in isothiocyanates and sulforaphane, which help fight cancer.

Broccoli

1. Broccoli is an excellent source of isothiocyanates which fights cancer.

2. It also contains indole-3-carbinol which helps to reduce breast and cervical cancer in women.

3. It's good for men too because of the high levels of sulforaphane, which increase the activation of enzymes that fight carcinogens and reduce the risk of prostate cancer.
