Some studies have looked at diet mainly in the prevention of lung cancer. Highlights of these studies that looked at certain foods include:
* A high fat diet raised the risk of the disease.
* Diets high in fruit are linked with a lower risk of cancer of lung, and in fact, the National Cancer Institute has predicted that foods high in flavenoids, like apples, can lower the risk of the disease by 50%.
* In women, the intake of dairy products and vegetables has been connected with a lower risk of the cancer in smokers, and black tea with a lower risk in non-smokers.
* Foods high in lutein, for example collard greens, spinach, broccoli, and orange juice, are linked with a lower risk of the cancer.
* Foods high in lycopene, for example tomatoes and particularly tomato sauces, are connected with a lower risk of lung cancer.
Factors of dietary are predicted to account for about 30% of cancers in western countries, making diet second simply to tobacco as a preventable cause of cancer. This amount is considered to be approximately 20% in developing countries and is projected to develop.
As developing countries become urbanised, patterns of cancer, mainly individuals most strongly linked with diet and physical activity, have a tendency to shift towards the patterns of economically developed countries. Cancer rates also alter as populations move between countries and take on different dietary patterns.
Tobacco smoke is the biggest carcinogen, responsible for 85% of all lung cancers in the United States. Risk rises with the number of tobacco used, and the number of time it has been used.
The best way of prevention is to never begin smoking or making use of chewing tobacco, or to discontinue using tobacco products. A healthy diet is an significant part of prevention.
In current years, considerable evidence has pointed to the connection from overweight and obesity, to a lot of types of cancer like oesophagus, colorectum, breast, endometrium and kidney. The composition of the diet is also significant because fruit and vegetables might have a protective effect by lessening the risk for a number of cancer types.
