**Data source**
The nutrition database (`assets/therapy/nutrition_database.json`) is structured around organ systems, with each organ entry containing:
– **Key nutrients** — vitamins, minerals, and cofactors known to support that organ
– **Color-coded foods** — foods grouped into 7 diet colors (Red, Orange, Yellow, Green, Blue/Purple, White, Brown)
– **Supportive herbs** — culinary and medicinal herbs cross-referenced to that organ
– **Organ support notes** — brief clinical rationale for the dietary approach
**The 7-Color Diet framework**
The color system is derived from the phytonutrient literature: each color group provides a different spectrum of antioxidants, flavonoids, and co-factors. The panel presents color groups as visual chips so practitioners can give patients an intuitive shopping guide.
| Color group | Representative phytonutrients |
|————-|——————————-|
| Red | Lycopene, anthocyanins |
| Orange | Beta-carotene, hesperidin |
| Yellow | Lutein, zeaxanthin |
| Green | Chlorophyll, sulforaphane, folate |
| Blue/Purple | Resveratrol, anthocyanins |
| White | Quercetin, allicin (alliums) |
| Brown | Lignans, beta-glucans (whole grains) |
**When an iris zone maps to multiple organs** (e.g. the lower-basal zone maps to Kidney + Adrenal + Leg), the engine merges the nutrient, food, and herb lists from all matched organs and de-duplicates them. The `matchedOrgans` list on each card shows which organs contributed data.
**What the panel shows**
Each card displays:
– **Zone and organ**, finding type badge, severity
– **Key nutrients** — listed in priority order
– **Color-food grid** — up to 4 foods per color group, displayed as colored chips
– **Supportive herbs** — small herb chips distinct from the herbal recommendations module
– **Organ support note** — a one-sentence clinical rationale for the dietary focus
