Honey is not a magic substitute for sugar if you have type 2 diabetes, but it’s not off-limits either. A tablespoon of honey contains about 17 grams of carbohydrates, and it will raise your blood sugar. The real question is whether it behaves any differently than regular table sugar in your body, and the answer is nuanced.
How Honey Compares to Sugar
Honey has an average glycemic index of about 55, compared to 68 for table sugar. That means honey raises blood sugar more slowly and to a somewhat lower peak. In clinical testing, honey produced a lower blood sugar spike than table sugar in both people with diabetes and those without. It also triggered a lower peak insulin response than sucrose, meaning your body didn’t have to work as hard to process it.
That said, honey is still a concentrated source of sugar. It’s roughly 80% carbohydrates by weight, mostly fructose and glucose. Teaspoon for teaspoon, honey actually contains slightly more carbohydrates and calories than granulated sugar. The practical advantage is that honey tastes sweeter, so you may use less of it. But the savings are minimal. Mayo Clinic’s position is straightforward: there’s generally no advantage to substituting honey for sugar in a diabetes eating plan.
What the Research Shows
A systematic review looking at eight clinical studies found that blood sugar or HbA1c (a marker of long-term blood sugar control) was significantly reduced after honey consumption in seven of those studies. However, two studies found no meaningful difference, and two others actually showed increases in blood sugar following honey intake. The researchers concluded that the evidence is too limited to make a definitive claim about honey’s effect on blood sugar management in diabetes.
Lab research has uncovered some interesting mechanisms that could explain why honey might behave slightly better than plain sugar. Bioactive compounds in honey appear to block an enzyme that normally puts the brakes on insulin signaling in cells. In liver cells, honey extracts increased the number of insulin receptors on the cell surface and improved glucose uptake. These findings suggest honey’s natural plant compounds could have a modest positive effect on how your body responds to insulin, something refined sugar simply doesn’t offer.
The catch is that these are cell-level findings. Whether eating a teaspoon or two of honey daily translates into meaningful improvements in insulin sensitivity for a person with type 2 diabetes hasn’t been conclusively proven in large human trials.
What Makes Honey Different From Plain Sugar
Honey isn’t just sugar dissolved in water. It contains small amounts of antioxidants, flavonoids, and other plant-based compounds that refined white sugar lacks entirely. These compounds are what give honey its potential metabolic benefits in the lab studies described above. Raw, unprocessed honey retains more of these compounds than commercially filtered varieties.
The type of honey also matters. Darker honeys like buckwheat or manuka tend to contain higher concentrations of antioxidants. Lighter, mass-produced honeys found in squeeze bottles at the grocery store are often heavily processed and may have lost many of these beneficial compounds, making them functionally closer to plain sugar.
How Much Is Safe to Use
If you enjoy honey and want to include it in your diet, the generally recommended serving for people with diabetes is 1 to 2 teaspoons per day. That’s significantly less than a full tablespoon, and it matters. One teaspoon contains roughly 6 grams of carbohydrates, which is manageable within most meal plans. Two teaspoons puts you at about 12 grams, still a modest amount but worth tracking.
The key is treating honey the same way you’d treat any other added sugar: count the carbohydrates, factor it into your total meal, and check your blood sugar afterward to see how your body responds. People with type 2 diabetes vary widely in their individual responses to different foods, so what spikes one person’s blood sugar may be fine for another. Testing after meals gives you real data about how honey affects you specifically.
Practical Tips for Using Honey
Because honey is sweeter than sugar by volume, you can often use less of it. If a recipe calls for a tablespoon of sugar, try two teaspoons of honey instead. Stirring honey into hot tea or drizzling it on oatmeal is a common use, but keep in mind that oatmeal already contains carbohydrates, so you’re stacking sugar sources in one meal.
Avoid using honey as a “health food” replacement for sugar throughout the day. The lower glycemic index doesn’t make it free. It still counts toward your total carbohydrate intake, and consuming it liberally will raise your blood sugar just as any other sweetener would. The modest biological advantages honey may have over refined sugar exist only at small doses. At larger portions, those advantages are overwhelmed by the sheer amount of glucose and fructose entering your bloodstream.
If you’re choosing between adding a teaspoon of honey or a teaspoon of white sugar to your morning coffee, honey is the marginally better option. If you’re choosing between a teaspoon of honey and no added sweetener at all, skipping it entirely will always be better for blood sugar control.
