Food & Physical Activity for Cancer Prevention:

How to Bring the Science to Life Food & Physical Activity for Cancer Prevention

Learning Objectives:

Learning Objectives Discuss the role for registered dietitians in cancer prevention. Use the Second Expert Report, “Food, Nutrition, Physical Activity, and the Prevention of Cancer: A Global Perspective,” and the Continuous Update Reports produced by AICR and World Cancer Research Fund as a foundation for cancer prevention advice to individuals and groups . Compare and contrast the different levels and types of evidence related to specific lifestyle factors and cancer prevention, using the various methods of data presentation in the Second Expert Report. Describe the five key components of the process used to develop the Second Expert Report.

Why Cancer Prevention?:

Why Cancer Prevention? The good news: New cancer diagnoses and deaths have decreased (1999 - 2006) It’s all relative. The other stats on cancer: Causes 1/4 of U.S. deaths #2 cause of death behind heart disease Half of men and 1 in 3 women will get cancer in their lifetime Global burden of cancer will increase (Edwards et al 2009; NCI, 2009; U.S. Mortality, 2007; WCRF/AICR, 2007)

AICR/WCRF Expert Reports:

AICR/WCRF Expert Reports Food, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective , 1997 Second Expert Report, 2007 Continuous Update Project: Breast Cancer, 2009 In development: Prostate, Colorectal, Pancreatic cancers; Breast Cancer Survivors

The Recommendations:

The Recommendations

Recommendations for Cancer Prevention:

Recommendations for Cancer Prevention Be as lean as possible within the normal range of body weight. Be physically active as part of everyday life. Limit consumption of energy dense foods. Avoid sugary drinks. Eat mostly foods of plant origin. Limit intake of red meat and avoid processed meat.

Recommendations for Cancer Prevention:

Recommendations for Cancer Prevention Limit alcoholic drinks. Limit consumption of salt. Aim to meet nutritional needs through diet alone. Mothers to breastfeed, children to be breastfed. For cancer survivors, follow the recommendations for cancer prevention.

Issues in Interpretation of Evidence:

Issues in Interpretation of Evidence Dietary intakes and patterns highly variable Classification of behaviors inconsistent Measurement of data imprecise Disagreement regarding appropriate interpretation of various types of research and totality of evidence Confounding factors poorly controlled or unknown Effects of production, preservation, processing, preparation, and overall dietary patterns poorly understood

Inferring Causality:

Inferring Causality Causal relationships can be confidently inferred when epidemiological, experimental, and other biological findings are: Consistent Unbiased Strong Graded Coherent Repeated Plausible

Criteria for Grading Evidence: Justifies Recommendation:

Criteria for Grading Evidence: Justifies Recommendation Data that meet the criteria for Convincing or Probable cause of cancer justify making a recommendation for that factor. Convincing More than one type of study ≥ 2 independent cohort studies No substantial unexplained heterogeneity Quality of studies excludes random or systematic error Plausible biological dose-response relationship Strong and plausible experimental evidence that typical human exposures can lead to cancer outcomes Unlikely to change over time Probable ≥ 2 independent cohort OR ≥ 5 case-control studies No substantial unexplained heterogeneity Quality of studies excludes random or systematic error Biological plausibility

Criteria for Grading Evidence: Justifies Recommendation:

The criteria for Substantial Effect on Risk Unlikely are similar to the criteria for a Convincing cause of cancer. It has resulted in certain factors ( eg , coffee) being ruled out as a cancer concern. Substantial E ffect on Risk Unlikely More than one type of study ≥ 2 independent cohort studies Summary estimate of effect close to 1.0 No substantial unexplained heterogeneity Quality of studies excludes random or systematic error Absence of dose-response relationship Absence of strong and plausible experimental evidence that typical human exposures can lead to cancer outcomes Unlikely to change over time Criteria for Grading Evidence: Justifies Recommendation

Criteria for Grading Evidence: No Recommendation Can Be Made:

In contrast, data that meet the criteria only for limited-suggestive or limited-no conclusion are insufficient to justify a recommendation. More evidence is needed in these cases. Limited-suggestive ≥ 2 independent cohort OR ≥ 5 case-control studies Some heterogeneity, although direction of effect generally consistent Biological plausibility Limited-no conclusion Sufficient data to warrant Panel consideration, insufficient to inform conclusion Criteria for Grading Evidence: No Recommendation Can Be Made

Displaying Judgment of Evidence:

Displaying Judgment of Evidence TOP BOX : Convincing or Probable relationship , justifies recommendation MIDDLE BOX : Limited suggestion of relationship, no recommendation BOTTOM BOX : Convincing evidence of NO effect, justifies recommendation

Reshaping Meals:

Reshaping Meals Be prepared Focus on healthful fats Monitor portions Start with soup or salad Pile on veggies and fruits Choose beverages wisely

When changes are tough…:

When changes are tough… Motivation is Key

When changes are tough…:

When changes are tough… Specific alternatives are important Incorporate fiber and fluids to improve satiety Address convenience

The Cancer Prevention Message is Clear:

The Cancer Prevention Message is Clear Be as lean as possible within the normal range of body weight. Be physically active as part of everyday life. Limit consumption of energy dense foods. Avoid sugary drinks. Eat mostly foods of plant origin. Limit intake of red meat and avoid processed meat. Limit alcoholic drinks. Limit consumption of salt. Aim to meet nutritional needs through diet alone. Mothers to breastfeed, children to be breastfed. For cancer survivors, follow the recommendations for cancer prevention.

The Cancer Prevention Message is Clear:

The Cancer Prevention Message is Clear Many questions warrant further research, and the data will be assessed on an ongoing basis. Today, the RD plays a critical role in bringing the cancer prevention message to life for the public in a manner that is meaningful and sustainable.
