Experts think that up to 1 in 10 cancers (10%) in the UK may be linked to diet. There’s a lot of research being done into which types of food may affect our risk of developing cancer.
Research suggests that a lack of fruit and vegetables in the diet may contribute to about 6 in 100 cancers (6%) in men. And being overweight may contribute to about 7 in 100 cancers (7%) in women. There are many reasons why people are overweight, but an unhealthy diet and lack of physical activity are often factors.
Our diets are made up of many types of foods, which in turn are made up of thousands of different substances. Some of these may increase our risk of cancer, but others may protect us. How diet affects our risk of developing cancer is complicated, and we still don’t completely understand it.
Despite this, we do know that a balanced diet and regular exercise help us keep to a healthy weight, which can help reduce the risk of developing some cancers.
