Objectives: To discuss the relationship between weight management and diet and cancer prevention, current nutritional guidelines, and evidence-based strategies to reduce cancer risk.
Data sources: Current nutritional guidelines, journal articles published between 2012 and 2015, and internet resources.
Conclusion: Evidence indicates that attaining and/or maintaining a healthy weight and adopting a diet that is primarily plant-based, low in red and processed meats, simple sugars, and refined carbohydrates, limits alcohol, and relies on food for nutrients can aid in preventing cancer.
Implications for nursing practice: Nurses can take the lead to educate patients and families about weight management and diet and to promote adherence to nutritional guidelines.
