Honey can fit into a prediabetes eating plan, but it still raises blood sugar and needs to be treated as an added sugar. The good news is that honey has a lower glycemic index than table sugar (about 55 versus 68), meaning it causes a slower, more moderate rise in blood glucose. That difference matters when you’re managing prediabetes, but it doesn’t make honey a free pass.
How Honey Compares to Table Sugar
Honey and white sugar are both mixtures of glucose and fructose, but their proportions differ. Table sugar is a rigid 50/50 split. Honey leans slightly toward fructose, with fructose-to-glucose ratios ranging from about 1.03 in cotton honey to 1.54 in tupelo honey. Clover honey, the most common variety in the U.S., sits around a 1.09 ratio.
This matters because fructose doesn’t spike blood sugar the way glucose does. It’s processed primarily by the liver rather than flooding the bloodstream directly. That’s one reason honey’s glycemic index averages around 55, placing it in the “low to moderate” range, while table sugar lands at 68. In practical terms, a teaspoon of honey in your tea will raise your blood sugar less sharply than a teaspoon of white sugar. But a tablespoon of honey still contains roughly 17 grams of sugar and 64 calories, so the advantage disappears quickly if portions grow.
What the Research Shows
A large cross-sectional study published in the British Journal of Nutrition looked at over 18,000 adults and found that moderate honey consumption was associated with lower rates of prediabetes. Compared to people who almost never ate honey, those who consumed it four to six times per week had roughly 23% lower odds of having prediabetes. Even daily consumers showed about 15% lower odds.
People in the study who ate more honey also tended to have lower fasting blood sugar, lower triglycerides, lower blood pressure, and higher levels of HDL (the protective cholesterol). That’s an encouraging pattern, but it comes with an important caveat: this was a snapshot study, not an experiment. It can’t prove honey caused those better numbers. It’s possible that people who choose honey over other sweeteners also make other healthier choices that explain the results.
Separately, honey contains phenolic acids and flavonoids, compounds with anti-inflammatory and antioxidant properties. Some research has linked these compounds to reductions in blood sugar, fructosamine, and glycated hemoglobin (HbA1c, the marker that reflects your average blood sugar over two to three months). These effects appear modest, and they depend on the type and quality of honey you’re eating.
What Nutrition Guidelines Say
The American Diabetes Association notes that healthy eating patterns for people with diabetes also apply to prediabetes. Within its Mediterranean-style meal pattern, one of the approaches it highlights, the guidance is clear: “concentrated sugars or honey rarely.” That’s not a ban, but it places honey in the same category as other added sweeteners, something to use sparingly rather than freely.
The ADA doesn’t set a specific teaspoon limit for honey. What it emphasizes is overall carbohydrate quality and total sugar intake. If you’re swapping honey for table sugar in a recipe or your morning coffee, that’s a reasonable trade. If you’re adding honey on top of what you already eat, you’re just increasing your sugar load.
How to Use Honey Practically
One to two teaspoons at a time is a sensible serving for someone managing prediabetes. That gives you about 6 to 12 grams of sugar, enough to sweeten oatmeal or a cup of tea without dramatically affecting your blood glucose. Keeping it to a few times per week, rather than multiple times daily, aligns with both the research data and general dietary guidelines.
A few strategies can blunt honey’s impact on your blood sugar:
- Pair it with protein, fat, or fiber. Honey drizzled on Greek yogurt with nuts, or stirred into oatmeal, will be absorbed more slowly than honey eaten on its own or on white toast.
- Use it as a replacement, not an addition. If you’re currently using sugar in a recipe, try two-thirds the amount of honey instead. Honey is sweeter by volume, so you need less.
- Watch liquid sources. Honey in tea, smoothies, or salad dressings adds up fast because it’s easy to pour more than you intended. Measure rather than eyeball.
Raw Versus Processed Honey
Raw honey retains more of its natural antioxidants and phenolic compounds because it hasn’t been heated during pasteurization. Commercial, heavily filtered honey may lose some of these beneficial compounds during processing. From a blood sugar standpoint alone, the glycemic index doesn’t differ dramatically between varieties. Where raw honey may have an edge is in delivering more of the anti-inflammatory compounds that appear to support metabolic health. If you have the choice and the budget, raw or minimally processed honey is the better option.
The Bottom Line on Honey and Prediabetes
Honey is not off-limits with prediabetes, and it’s a better choice than table sugar or high-fructose corn syrup when you want something sweet. Its lower glycemic index, natural antioxidants, and association with favorable metabolic markers all work in its favor. But it’s still a concentrated source of sugar. Keeping portions small, pairing it with other foods, and treating it as an occasional ingredient rather than a health food is the approach most likely to support your blood sugar goals.
