Honey
Rating: depends on portion · Trigger subgroup: Excess fructose
At a 2 g portion: green light
Lights per subgroup
- Fructans 0.01 g · green light
- GOS 0 g · green light
- Excess fructose 0.1 g · green light
- Lactose 0 g · green light
- Sorbitol 0 g · green light
- Mannitol 0 g · green light
fructans and GOS are evaluated together (oligosaccharide sum) · sorbitol and mannitol are evaluated individually and combined — the worse result wins
Green boundaries come from the scientific sources; the amber (1–2× the cutoff) and red (>2×) bands are an app estimate.
Fructose absorption depends on glucose across the whole meal — per-ingredient derivation is a deliberate simplification.

Sources
- USDA FDC 169640 — honey: fructose 40.94 − glucose 35.75 = excess 5.19
- White & Doner 1980, USDA Agriculture Handbook 335 pp. 82–91 (avg floral honey 'higher sugars' 1.50 g/100g, range 0.13–8.49; ten trisaccharides mostly glucose-based, 1-kestose at trace level)
- fructans 0.3 = conservative upper-bound ESTIMATE (confidence low) for the inulin-type share of the higher-sugars fraction — pending dietitian review; deliberately non-zero so the sole-fructose 0.40 relaxation stays OFF (estimate must not improve the light)

Hollow circle = no data (unknown). Hatched = medium/low confidence. Solid = high confidence.
