Tomatoes
Tomatoes are one of the richest sources of the flavenoid lycopene - which gives them their red colour - which has shown to defend, in study after study, against cancers of the lungs, cervix, prostate and mouth.

Cabbages
All cabbages, including their kin broccoli, cauliflower, kale are not only rich in calcium, but recent research has shown that they are also extremely rich in anti-cancer flavonoids.Red Cabbage is the richest source of flavonoids.

Spinach
Spinach is also a rich source of vitamin C, beta-carotene, both are potent antioxidants as well as folic acid. In several studies has been found that people who include two or more servings of spinach per week in their nutrition have considerably lower lung and breast cancer rates. 

Beans
All kinds of beans are loaded with protease inhibitors, compounds that make it hard for cancer cells to invade adjacent tissue. Much recent research shown to block carcinogens in the digestive tract. And soy beans are especially rich in isoflavones, which appears to reduce the risk of breast cancer by blocking the tumor-growing influence of estrogen.

Garlic
The sulphur compounds that give it its strong flavour have now been shown to protect against cancer by neutralizing carcinogens and slowing tumor growth. In a recent Women's Health study, investigators found that women who consume garlic at least once a week also have a 32% lower incidence of breast cancer.

Oranges
Oranges are rich in many other potent anti-cancer compounds. Investigators have now found that oranges contain more than 170 photochemicals, including more than 20 from the potent carotenoid family alone. In addition, compounds called limonoids which give citrus fruit their slightly bitter taste appear to be highly active anti-cancer agents as well. Regular consumption of oranges is associated with significantly lower lung and stomach cancers.

Blueberries
Especially in wild species, blueberries contain anthocyanins, other antioxidant pigments and various phytochemicals possibly having a role in reducing risks of some diseases, including cancers.

Strawberries
In a study found that people who love strawberries have a 70% lower incidence of cancer. The same holds true for all other colourful and deeply coloured erries, such as cranberries, raspberries, blackberries, blueberries, red and purple grapes, and so forth.

Whole Wheat
In a recent study found that the more whole grain there is in a woman's diet, the lower her risk of breast cancer, as well as heart disease. At the same time, investigators established that consumers of whole wheat products (bread,asta, cereals) have a 33% lower risk of these diseases than those who do not eat whole wheat products.
