Food Compatibility Data
Structured food compatibility data extracted from the SIGHI Food Compatibility List (2024-08-29 edition) for use in the Confidente app’s seed data and analysis engine.

How this data maps to the app schema
The SIGHI list uses a 0-3 compatibility scale. We map it to the app’s food_category_memberships.severity field:
| SIGHI Score | Meaning | App Severity |
|---|---|---|
| 0 | Well tolerated | (not stored — no membership created) |
| 1 | Moderately compatible | low (0) |
| 2 | Incompatible | medium (1) |
| 3 | Very poorly tolerated | high (2) |
The mechanism codes (H, H!, A, L, B) map to food_sensitivity_categories:
| Code | Mechanism | App Category |
|---|---|---|
| H | High histamine content | histamine |
| H! | Highly perishable, rapid histamine formation | histamine (freshness-dependent) |
| A | Other biogenic amines | biogenic_amines |
| L | Histamine liberators (mast cell activators) | histamine_liberator |
| B | DAO inhibitors | dao_inhibitor |
Important context from SIGHI
The “Histamine” column does NOT show histamine content — it shows perceived compatibility for histamine-sensitive persons. Compatibility results from multiple factors: liberators, histamine, other amines, DAO inhibitors, consistency, and mast cell stabilizing ingredients.
Salicylate content is NOT factored into the histamine column. Salicylates are a separate trigger that affects only some MCAS sufferers. See Sensitivity Categories for how this maps to our category system.
Tolerance is dose-dependent and individually variable. The list is a starting point for the elimination phase, not a permanent restriction.
