The power is double edged. Malnutrition increases the risk of cancer, but a good, balanced diet reduces the risk of cancer.

Food is one of the most important factors of life and has been estimated at nearly 80% of cancers of the large intestine, breast and prostate cancer. Diet influences the risk for many other cancers, including tumors of the lung, prostate, stomach, esophagus and pancreas.

Prostate Cancer:
High consumption of meat, especially red meat, substantially increases the risk of prostate cancer.

Vegetables, cooked tomatoes, to avoid the risk of prostate cancer. In a clinical study, the role of vitamin E as a factor was to reduce prostate cancer. In this study, there was a 32% reduction in the incidence of prostate cancer and 41% decrease in mortality from prostate cancer in humans, vitamin E, Denmark, when compared to controls .

Breast Cancer:
In Japan, people eat tofu, soy, a product. It contains isoflavones that moderate the estrogen receptors in the body, such as breast tissue. The incidence of breast cancer in Japan compared to Western women, only 1/4th of the mortality of western women. Japanese women diet low in fat, high fish drink green tea and also reduce their risk of breast cancer.

A case-control study found that regular soy food was related to a significant reduction in risk of breast cancer in pre-menopausal women. No effect in women after menopause.

A Japanese case-control study was also found that the registration of tofu (3 times per week, compared to less than 3 times / week) was in the context of reducing the risk of breast cancer in women pre - menopausal. In addition, the soybean was not taken measures to protect against breast cancer after menopause.

In a study in the United States, the relationship between the recording of soy and breast cancer risk found that protective measures were pre-menopausal tofu and Asian women after menopause.

Lung Cancer:
Risk of lung cancer is significantly decreased by a large number of carotenoids. Carotenoids, antioxidants and thus minimize the damage of cells.

A study in Boston focused on the effects of different types of carotenoids to risk of lung cancer. It was found that the risk of lung cancer was significantly lower among people who consume a high in a number of carotenoids. This has been primarily with non-smokers, 63% less risk.

A study conducted in Hawaii reported further evidence of a protective effect from certain carotenoids against lung cancer and more protection is that, by consuming a variety of vegetables compared to only a diet rich in certain carotenoids.

Stomach Cancer:
Nitrates in food and other preservatives in foods such as meat are Nitrates in the human stomach. Nitrite nitrosation under “and nitrosamides nitrosamines. This increases the risk of stomach cancer in people eating vegetables from nitrate rich soil.

In one study, vitamin C appeared to protect against the risk of stomach cancer by inhibiting the formation of nitrate in the stomach.

Gastric cancer is 5 times more often in Japanese people compared to western populations. If Japanese people migrated to the United States to proceed by steps on the low incidence of the United States due to changes in their diet.

In a study conducted in Hawaii, both Japanese and Caucasians, the risk of stomach cancer was with consumption of rice, vegetables, pickled and dried / salted fish, and a negative association with vitamin-C-Food .

An ecological study in Belgium showed a link between pollution by nitrates and salt and gastric cancer. The analysis showed that this model the importance of nitrate as a risk factor for stomach cancer mortality increased significantly with higher levels of sodium.

Dietary habits and risk of stomach cancer was in Shanghai, China. According to this study, the risk of stomach cancer have been reversed in the context of a high intake of several groups of foods, including fresh fruit and vegetables, poultry, eggs, vegetable oil, and certain nutrients such as proteins, fats, fiber, tea antioxidants and vitamins.

However, the risk increases with increased consumption of dietary carbohydrates, frequent consumption of preserved foods, fried foods or salt and hot soup / porridge, with irregular meals, speed and food binge eating. This shows that diet plays an important role in stomach cancer risk.

Not a single food supplements to prevent cancer, but a balanced combination of different groups can help. Diet can prevent 3-4 million cancers each year.
