False positive results for metanephrine testing are a well-documented issue, with one case study confirming that a catecholamine-rich diet can significantly impact test outcomes. This highlights why it is critical to understand if and how diet can affect metanephrine levels, especially when being screened for rare adrenal tumors.

This phenomenon prompts a deeper question: **do bananas raise catecholamines** in a significant way that affects the average person?
