The tumors are one of the most common causes of death in Western societies. Causes the onset of cancer are different depending on the type of cancer, but most of neoplastic diseases can be traced to a mix of genetic and environmental causes .
The Diet certainly plays an important role in the onset of tumors in this regard, to set a correct strategy cancer, there are two different types of strategies that use diet as a means of combat cancer.
fact may be present in our diet foods that promote the onset of cancer or even clearly carcinogenic substances .
anti-cancer diet should minimize and possibly eliminate these substances properly choosing the correct foods and cooking systems by adopting a strategy of elimination of substances that promote the onset of cancer. On the other hand, many foods contain substances protective against the onset of cancer, although many of them have no definitive studies have been performed, and then remain big question marks about their real effectiveness. This is why this active strategy of prevention against cancer, should be considered only after having successfully adopted the strategy of eliminating the above.>
Diet and cancer: the elimination strategy
factor is the easiest to eliminate overweight, that is excess calories. The fact that overweight and obesity promote the onset and development of most cancers is a well established fact: the higher the amount of body fat, the greater the likelihood of developing cancer. A body fat percentage lower than 12% for men and 20% for women is easily accessible and maintainable by all the people and ensures a low probability, consistent with their own genetic characteristics of cancer.
The second thing to check is the intake of foods that contain carcinogens. among these, the most widespread and dangerous are nitrosamines, which are not contained directly in foods, but they appear in the body following ingestion of nitrites used as food additives (E250, E249) in many meats and meat and preserved fish. To eliminate from the diet is sufficient to choose nitrite cured meats and other products without nitrite, reading labels and selecting quality manufacturers that do not use it.
Some vegetables such as beets, spinach, turnips and celery contain significant amounts of nitrates, nitrites can be converted under certain conditions: therefore, you should limit your intake of these vegetables, or rely on crops with low environmental impact, or even better organic farming.
Other carcinogens such as benzopyrene , are contained in foods cooked at high temperatures, especially in the meat roasted on the grill or otherwise subjected to excessive temperatures. Use every day in the diet of delicate dishes, such as steaming, boiling and steaming and limit high-temperature cooking (such as frying and baking to roasting) to special occasions, with a maximum frequency of once a week, is certainly a good strategy to limit the risk of cancers of the stomach and intestines.
Even alcohol is responsible for the onset of certain cancers, not only of the liver, but also the esophagus and pancreas.
Diet and cancer: the active strategy
This strategy consists in the diet of substances with proven antitumor action. Over the past twenty years there was much talk of food rich in substances with antioxidant and anticancer activity. The first foods to be promoted in an anticancer diet are the simple vegetable that is fruit and vegetables, with some of them in the first place, such as cabbage, especially broccoli, but the tomatoes with lycopene , red oranges with their particular pigments. Almost all of those in weight eat lots of fruits and vegetables, offering a high satiating power with few calories. So, just eat fruit and vegetables in season, varying during the year the variety of plants, to ensure good coverage of all the vitamins, minerals and trace elements that guarantee a good functioning of the body and a good intake of protective substances against cancer.
Then they came to the fore other foods, first of all the green tea, but also fermented milk and other foods rich in antioxidants. Yogurt is a food certainly very interesting element in the diet of many people in weight. The choice of a probiotic yogurt be included in the diet instead of regular yogurt is probably a positive factor in relation to defense against tumors. Even green tea, when taken without sugar, as replacement drink water, then drink in quantity is not minimal, at least half a liter per day, is an excellent food that is often very helpful and has a dual significance, because it take plenty of water to those who do not like drinking water alone and that they often take too little can cripple the kidneys.
The effectiveness of these foods in the diet as factors in cancer is still much to prove and therefore believe that it is worth investing energy in order to adopt a strategy against tumors of this kind unless it has invested in what counts, namely the achievement the weight and the drastic reduction of carcinogens in food, through proper food choices and adopt healthier cooking systems.
