Is honey healthier than sugar? What controlled trials actually show

Barely. Honey and table sugar are both what nutrition scientists call free sugars, and the case that swapping one for the other improves your health is weak. Controlled trials do hint that honey nudges some cardiometabolic markers in a favourable direction, but the certainty behind almost every one of those findings is low, and honey remains an added sugar that dietary guidance says to limit [s1]. Treating it as a health food rather than a slightly different sweetener gets the evidence backwards.

The same category of sugar

Honey is mostly fructose and glucose dissolved in a little water; table sugar is sucrose, which the gut splits into those same two sugars. Their calorie contents are close enough that no one loses weight by switching. The reason honey keeps its health halo is not its composition but a scatter of trials suggesting it behaves a little differently in the body — a claim worth taking seriously precisely because it is testable. Honey does contain trace enzymes, antioxidants and pollen that refined sugar lacks, but the quantities are tiny relative to the sugar load that comes with them. The largest synthesis to date put the clinical trials together, and its results are more modest than the marketing.

What the pooled trials show

A 2022 systematic review and meta-analysis of controlled trials, assessed with the GRADE framework, pooled 18 trials — 33 trial comparisons, 1,105 participants — testing oral honey against a control [s1]. Honey was associated with a lower fasting glucose (mean difference −0.20 mmol/L, 95% CI −0.37 to −0.04), lower total cholesterol (−0.18 mmol/L, −0.33 to −0.04), lower LDL cholesterol (−0.16 mmol/L, −0.30 to −0.02), lower fasting triglycerides (−0.13 mmol/L, −0.20 to −0.07), and lower alanine aminotransferase, a liver enzyme (−9.75 U/L, −18.29 to −1.21) [s1]. It also raised HDL cholesterol (+0.07 mmol/L, 0.04 to 0.10) [s1].

The size of those numbers matters as much as their direction: a fasting-glucose drop of 0.2 mmol/L is small, and the authors graded the certainty of every one of these results as low — except the HDL increase, rated high [s1]. They also found the benefits concentrated in specific honeys: robinia, clover and raw, unprocessed honey drove the effects on glucose and cholesterol, while processed honey did less [s1]. In plain terms, the average jar on a supermarket shelf is not the product that generated the best numbers.

The one head-to-head against sugar

The most direct test is a small Iranian trial that pitted honey against sucrose rather than against nothing [s2]. It randomised 55 overweight or obese patients to 70 g a day of either natural honey (38 people) or sucrose (17 people) for 30 days [s2]. In the honey group, body weight fell about 1.3% and body fat about 1.1%, total cholesterol dropped 3%, triglycerides 11%, fasting blood glucose 4.2% and C-reactive protein 3.2%, while HDL rose 3.3% [s2]. The investigators concluded that honey did not raise body weight and reduced several risk factors, especially in people whose values were already elevated [s2].

That is the strongest single result honey enthusiasts can point to, and it is not strong. The groups were unequal in size, the trial was brief, it was not blinded, and it measured biomarkers over a month rather than any health outcome [s2]. It is one input to the low-certainty pooled estimate above, not independent confirmation of it. A 30-day change in a blood marker is a long way from a reason to eat more sugar of any kind.

What to make of it

Put together, the honest reading is narrow. Honey may have a marginally better metabolic profile than refined sugar, the difference is small, the evidence is mostly low-certainty, and the effect depends on the type of honey [s1]. None of that makes honey a food to add for health. Both honey and sugar count fully towards the free sugars that guidance advises limiting, and the comparison that actually moves health outcomes is not honey versus sugar but less total added sugar versus more — the same arithmetic behind how much added sugar is too much. If you prefer honey's flavour, use it; just count it as sugar, because that is what it is.
