Mayo Clinic Mini-EAT

Functionality & Mechanism

Developed by Mayo Clinic, the Mini-Eating Assessment Tool (Mini-EAT) functions as a rapid dietary screener. The interface captures input on nine distinct food group consumption frequencies, including fruits, vegetables, whole grains, refined grains, fish, dairy, and sweets. This system is engineered for rapid completion within a clinical workflow, providing an efficient method to assess dietary patterns without requiring a comprehensive food frequency questionnaire. The tool generates a summary assessment based on validated item correlations.

Evidence & Research Context

• A validation study (N=661) demonstrated the 9-item Mini-EAT has a strong correlation (r=0.71) with the comprehensive Healthy Eating Index (HEI)-2015 score.
• The tool was systematically reduced from an initial 19-item survey to the final 9 items most predictive of dietary quality, maintaining its predictive ability.
• The validation cohort included adults from preventive cardiology, cardiac rehabilitation settings, and healthy volunteers, indicating its initial testing in relevant populations.
• The authors note that further research is required to establish the tool's validity across more diverse populations and clinical settings.

Intended Use & Scope

Primarily designed for clinicians, the Mini-EAT functions as a rapid, preliminary screening instrument to assess patient dietary patterns within a clinical workflow. It is not a comprehensive diagnostic tool and does not replace a full nutritional analysis. Results should guide patient-provider conversations and inform the need for a formal dietetic assessment.
