In what measure are the food and the physical activity able to reduce the risks of cancer? It is the question which answers the imposing report scientifique1 published lately by the network of the world Fund of research against the cancer (FMRC).
A panel of scientific experts examined close to 7 000 studies led through the world since 50 years. After five years of discussions, the panel emits some recommendations concerning the food and the physical activity that lean on the judged studies " convincing" either " likely". As the report indicates it, these recommendations should permit to reduce the cases of cancer in the world populations, to the condition to be respected to the letter,:
* To remain as thin as possible, while keeping a normal weight. To maintain an optimal weight all along life could be one of the main means to protect itself/themselves from the cancer.
* To make a physical activity curbed at least thirty minutes every day and to limit the sedentary activities.
* To restrict the contribution of food to strong caloric density. To avoid the sugary drinks, the prepared dishes as well as the fast restoration.
* To increase and to vary the consumption of food of plant origin, as the vegetables, the fruits, the complete cereals and the legumes, while limiting the starchy refined (white bread, dough’s, white rice or semolina). * to Limit the red meat consumption unless 500 G per week and to avoid the butcher’s shop. This food is considered like a reason " convincing" either " likely" of some cancers.
* To restrict the consumption of alcohol to a drink alcoholic per day for the women, and to two, for the men. The pregnant women and the children must not consume any alcoholic drinks.
* To avoid the salty food or kept by salting and limit the consumption of products containing salt added in order to arrive to a daily contribution in sodium lower to 2,4 g.
* To try to satisfy the nutritional needs solely by the food without resorting to the food complements. These last are not recommended for the prevention of the cancer.
The panel also underlines the importance not to smoke and to avoid the secondary smoke. The report also goes to specific groups. The women who have just given birth should feed their baby exclusively with the breast during the first six months, sustain the experts. For their part, people affected by a cancer would have to, after their treatment, to less of contrary opinion, to follow the set of these eight recommendations.
The FMRC will pursue its work of analysis during the next year in order to publish, end 2008, a new report with recommendations taking into account the social, cultural, economic and environmental factors partners to the cancer.
