Diet and Nutrition Advice After a Solid Tumor Diagnosis

Area of Science:

• Oncology
• Nutrition Science
• Evidence-Based Practice

Background:

• Credible diet and nutrition advice is crucial for cancer patients.
• Patients often face nutrition-impact symptoms during cancer treatment.

Purpose of the Study:

• To investigate the sources and nature of diet and nutrition advice received by cancer patients before their initial dietetic consultation.
• To understand patient perceptions of advice trustworthiness and adherence.

Main Methods:

• A multicenter observational study involving 77 cancer patients at their first dietetic assessment.
• Participants completed a questionnaire on advice received since diagnosis from various sources.

Main Results:

• 69% of patients received advice from professional and nonprofessional sources before their dietetic visit.
• Family and friends were common sources; advice often focused on food inclusion/avoidance, was frequently contradictory, and rarely evidence-based.
• Patients struggled to identify trustworthy advice but generally followed it.

Conclusions:

• Most cancer patients receive pre-dietetic advice, predominantly from nonprofessional sources, which can be inconsistent and contradictory.
• Patients often followed unreliable advice, highlighting a need for earlier, evidence-based dietetic interventions.
• There is a clear need for earlier professional dietetic consultation to manage symptoms and resolve conflicting advice.
