Does diet matter?
Many common cancers are linked to diet. Some types of food increase your risk, while others seem to have a protective effect. For example, a diet low in saturated fat, alcohol and red meat and high in fibre, fruit and vegetables can reduce your risk of some cancers, such as breast and colon cancer. Fruit and vegetables contain natural chemicals, antioxidants, that mop up free radicals: chemicals that can damage genes.
