About GutCode

GutCode helps you track meals, symptoms, and lifestyle factors to identify personal patterns. The app uses published scientific research as a foundation for its features and educational content. Nutrition estimates are approximate and should not be used for clinical dietary management.

AI-Powered Analysis: Food recognition and nutrition estimates are generated by artificial intelligence. These are approximate values and may not be accurate for all foods, portion sizes, or preparations. They are not a substitute for professional dietary assessment.

Limitations

Nutrition estimates are approximate. AI-generated values may differ from actual nutritional content due to portion size variation, food preparation methods, and ingredient differences.
Correlation is not causation. Patterns identified by GutCode (e.g., food-symptom links) reflect statistical associations in your personal data, not proven causal relationships.
Not for clinical use. GutCode is not intended to diagnose, treat, cure, or prevent any disease or medical condition.
Individual variation. Health responses to foods vary significantly between individuals. What the app suggests based on general research may not apply to your specific situation.
