Who we are What we doFund research on the relationship of nutrition,

physical activity and body weight to cancer risk

Interpret the accumulated scientific literature to derive Recommendations for Cancer Prevention

Educate people through our national Health Information programmes

Advocate effective policies to help people and populations to reduce their chances of developing cancer

The Continuous Update Project. Aims

Ensure everyone has accessBased on the most up to date scientific evidence

WCRF/AICR Recommendations for Cancer Prevention:

• Keep evidence, conclusions and recommendations updated into the future• Working with team at ICL• Same principles: - Systematically review evidence- Meta analysis - Panel of experts

- draw conclusions - make recommendations
