Ahead of Cancer Prevention Week (May 11-17), I am writing to let people in the local area know they can make a real difference to their cancer risk by making simple changes to their diet.

Research shows eating plenty of fruits and vegetables probably reduces risk of several types of cancer and this is why the World Cancer Research Fund recommends people eat at least five portions a day of a variety of fruits and vegetables.

We also recommend cutting down on intake of red and processed meat, salt and alcohol because of evidence that these increase risk.

Overall, scientists estimate about a third of the most common cancers could be prevented through eating healthily, being physically active and maintaining a healthy weight.

If your readers want to find out more about the links between diet and cancer, we are giving away a free copy of our Eating Well for Cancer Prevention booklet to the first 100 people who call 020 7343 4205 and quote “media”.
