GL = (GI × carbs per serving) ÷ 100 = (58 × 17.2) ÷ 100 = 10.0. GL ≤10 = Low · 11–19 = Medium · ≥20 = High (WHO/FAO classification).

Sweetener GI Comparison

* Maple syrup GI ~54 (sucrose-dominant; varies by grade). Agave nectar GI ~17 but extremely high fructose (~85 g/100 g) — low GI does not equal metabolically neutral.

GI Values for 18 Honey Varieties

Ranked lowest to highest GI. Values from Atkinson et al. (2008) and Bogdanov et al. (2008). Fructose % drives GI: higher fructose = lower GI.

Why Honey GI Varies So Much

Honey's glycemic index is determined by its fructose-to-glucose ratio. Fructose has a GI of ~19 (metabolised primarily by the liver without requiring insulin), while glucose has a GI of 100. High-fructose honeys like acacia and tupelo have a GI of 32–35 — half that of table sugar.

The ratio is set by the nectar source: black locust (Robinia pseudoacacia) blossoms produce nectar with an unusually high fructose fraction, while buckwheat and heather produce nectar closer to a 1:1 fructose-to-glucose ratio, raising the GI toward 65–73.

Note that even the highest-GI honeys (buckwheat, GI 73) have a glycemic load of 12–13 per tablespoon — in the medium range, comparable to a slice of wholegrain bread. For a 1 tsp serving, GL drops to ~4 for any honey variety, firmly in the low tier.
