A report by the World Cancer Research Fund says that 1/3 of cancers could be prevented if people ate less fat and sugar, exercised more, and got rid of their excess weight. How easy is that? They also said another 1/3 of cancers could be prevented by not smoking. The World Cancer Research Fund is calling on city governments to mandate walking and cycling paths in their towns to encourage people to get more exercise. They are also asking for better priced, healthier food choices from the food industry for consumers. In addition, they are recommending that all ads for sugary soft drinks and unhealthy foods aimed at children be banned.
