Glycemic Index of Honey: Sidr, Acacia, Robinia, and Sufeda Compared

Honey's glycemic index (GI) varies far more than most people assume, from around 32 for high-fructose varieties like Robinia (black locust) honey up to the mid-80s for glucose-dominant types like buckwheat honey, compared to roughly 60 to 65 for white sugar. The deciding factor is each honey's fructose-to-glucose ratio, the same chemistry that also determines how fast it crystallizes. Since honey with more fructose stays liquid longer and honey with more glucose crystallizes faster, crystallization speed is actually a useful clue to relative GI, even without a dedicated lab test for every variety. Below is what published research and that same fructose-glucose logic suggest for Sidr, Acacia, Robinia, and Sufeda (Eucalyptus) honey specifically.

What Is Glycemic Index, and Why Does It Vary So Much in Honey?

Glycemic index measures how quickly a food raises blood glucose after eating it, on a scale where pure glucose is set at 100. Honey is not one single GI value; published research shows it spans roughly 32 to the mid-80s depending on floral source, a wider range than almost any other sweetener category.

The reason comes down to honey's two main sugars, fructose and glucose. Fructose has a low GI on its own (around 19 to 23), while glucose sits at the top of the scale (100). A honey with a higher fructose-to-glucose ratio is absorbed more gradually and produces a lower GI, while a honey with more glucose relative to fructose spikes blood sugar faster and crystallizes sooner, since glucose is the sugar that falls out of solution to form crystals.

The Glycemic Index of Sidr, Acacia, Robinia, and Sufeda

No single lab test measures GI directly; it requires a human feeding trial with blood glucose sampled over time, so exact, variety-specific numbers for Pakistani honey are not independently published the way they are for a handful of well-studied types like Australian Robinia and Eucalyptus honey. What follows combines that published research with the fructose-glucose signature we already know from each variety's real-world crystallization behavior.

Worth being direct about one common point of confusion: in parts of Europe and Australia, honey labeled "acacia honey" is usually made from Robinia pseudoacacia (black locust) and carries the well-documented low GI of around 32. That specific, ultra-low figure applies to that slow-crystallizing, high-fructose honey, which lines up with the crystallization behavior we see in our own Robinia, not our Acacia variety, which crystallizes within weeks and therefore likely sits closer to honey's average GI. Sharing the name "acacia" does not guarantee sharing the same fructose-glucose chemistry.

For more on why crystallization speed differs across these same four varieties, see our guide on why honey crystallizes, and what that reveals about it.

How Honey's GI Compares to White Sugar

White sugar (sucrose) sits at roughly 60 to 65 on the glycemic index scale. Honey's published range runs from about 32 up to the mid-80s, meaning some honey varieties genuinely beat sugar on this measure while others do not. A honey with a high fructose ratio, like Robinia, or a naturally low-glucose variety like Sidr, is a meaningfully gentler choice than sugar. A fast-crystallizing, more glucose-dominant honey sits closer to sugar's own GI, still likely a bit lower, but not by a wide margin.

This is also why "honey is always better than sugar" is an oversimplification. The real answer depends on which honey, and how much of it.

Does a Lower GI Mean a Honey Is "Diabetic-Safe"?

No, and this matters more than the GI number itself. A lower GI means blood sugar rises more gradually, not that a food can be eaten freely. Honey is still a concentrated sugar source regardless of variety, and portion size affects blood glucose as much as GI does, sometimes more. For a full breakdown of how to actually use honey if you have diabetes, including portioning and what to watch for, see our guide on is honey safe for diabetics.

GI also should not be confused with calorie content. A lower-GI honey is not automatically lower in calories; all honey is calorie-dense regardless of its fructose-glucose ratio. If weight management is your goal rather than blood sugar specifically, see our guide on is honey good for weight loss for that distinction.

Frequently Asked Questions

What is the glycemic index of honey?

It varies widely by variety, from around 32 for high-fructose honeys like Robinia to the mid-80s for glucose-dominant types like buckwheat honey. There is no single GI value for "honey" as a category.

Which Bagh Honey variety has the lowest glycemic index?

Robinia and Sidr are likely the lowest, based on their naturally slow-to-no crystallization, a sign of a higher fructose-to-glucose ratio. Neither has been directly lab-tested for GI, since GI requires a human feeding trial rather than a standard purity test.

Is Acacia honey always low GI?

Not necessarily. The well-known ~32 GI figure often quoted for "acacia honey" internationally refers specifically to Robinia pseudoacacia, a slow-crystallizing, high-fructose honey. A fast-crystallizing Acacia variety, like ours, likely sits closer to honey's moderate average instead.

Is honey's glycemic index lower than sugar's?

Often, but not always. White sugar sits around 60 to 65. Some honey varieties fall well below that, while faster-crystallizing, more glucose-dominant honeys sit closer to sugar's own GI.

Does crystallization speed really relate to glycemic index?

Yes, both come from the same underlying chemistry: the ratio of fructose to glucose. More fructose means slower crystallization and typically a lower GI; more glucose means faster crystallization and typically a higher GI.

Can I rely on glycemic index alone to choose a honey for blood sugar management?

No. Portion size, overall carbohydrate intake, and individual blood sugar response all matter alongside GI. Speak with a doctor before making honey a regular part of a diabetes management plan.

What is the GI of Sidr honey?

No dedicated clinical GI trial has been published for Sidr honey specifically. Based on its naturally low glucose content and its slow-to-none crystallization, the same chemical signature seen in other low-GI honeys, it likely sits toward the lower end of honey's GI range, but this is an informed estimate, not a lab-confirmed number.

What is the GI of Robinia honey?

Likely low, in the range documented for Robinia pseudoacacia honey internationally, around 32. This honey's slow crystallization points to a high fructose-to-glucose ratio, the same profile associated with that low published figure, though our own batches have not been through a dedicated human GI trial.

What is the GI of Acacia honey?

Likely moderate, closer to honey's overall average rather than the ultra-low ~32 figure sometimes seen for "acacia honey" abroad. That low figure applies to Robinia pseudoacacia specifically, a slow-crystallizing honey; our Acacia crystallizes within weeks, pointing to a more glucose-dominant, moderate-GI profile instead.

What is the GI of Sufeda (Eucalyptus) honey?

Likely moderate to moderately high. Published Eucalyptus honey GI values vary widely by species, from around 35 up to over 70, and Sufeda's fast crystallization suggests a higher glucose ratio, putting it closer to the moderate-to-higher end of that range rather than the low end.
