Healthier diets could help prevent 1 in 10 cancers (10%) in the UK. A lot of research is being done into which types of food may affect our risk of developing cancer.
Research shows that being overweight increases the risk of developing some types of cancer. There are many reasons why people are overweight, but an unhealthy diet and lack of physical activity are often factors.
Some foods we eat may increase our risk of cancer, but others may protect us. How our diet affects the risk of developing cancer is complicated, and we still do not completely understand it. Research suggests that eating fruit and vegetables may reduce the risk of certain cancers.
What we do know is that a healthy, balanced diet and regular exercise helps us keep to a healthy weight. This can help reduce the risk of developing some cancers.
