Fruits and vegetables are very anti-cancer food? Bisphenol-free Bottle

this review I must point out recently in the British Journal of Cancer, written by Timothy Key, for the results rather disappointing that emerge from studies that have attempted to involve a high consumption of fruit and vegetables with a reduced risk of cancer.

In general, any recommendation for a healthy diet never fails to include a moderate intake of fruit and vegetables, if only to an extent sufficient to prevent deficiencies in vitamins and minerals. Vegetables are also rich in antioxidants, it goes without saying that the advice to eat in quantity to prevent cancer is almost spontaneous. In fact, this suggestion is not much supported by those who are the largest epidemiological studies of type "Point" where you collect data about the composition of the diet in a population of individuals associated with the risk of developing a cancerous disease in the years. An inverse association between consumption of fruits and vegetables and cancer risk (more high consumption of these foods, the lower the risk of cancer) is actually detected only in the case of a few types of cancer, such as those of the oral cavity, pharynx, esophagus and, to a limited extent, lung. But these are all diseases in which smoking is that the high consumption of alcohol plays a major role in increasing the risk. E 'is fairly well known that heavy smokers who are heavy drinkers are generally reluctant to consume large amounts of fruits and vegetables and this has been confirmed in several epidemiological studies. As for all other cancers consumption of fruits and vegetables does not seem to have great importance in terms of prevention, is the doubt that this association is simply an indirect effect of confounding due to dietary habits of those most at risk (smokers and drinkers).

In any case, however, it should be stressed however that obesity has a significant influence on cancer risk (as also noted the author of this review) is therefore always useful to remember that even though there seems to be a direct effect the prevention of cancer, high consumption of foods of plant origin can act if only indirectly, by reducing the caloric load of the diet and thus the risk of obesity.
