The Honey Files

The five claims, verdicted

Five claims, five verdicts. Here is what the research actually says.

1. 1.Honey is just sugar in a different format.

   PARTLY

   Mostly true: honey is about 82% sugar, and in the best head-to-head human trial it raised blood sugar, insulin, cholesterol and weight exactly like table sugar and corn syrup. But the small non-sugar fraction really does behave differently in tests.

2. 2.Honey’s sugar mix (fructose + glucose instead of one bonded sugar) is why it tastes and feels different.

   CONFIRMED

   Confirmed: honey is roughly 38% free fructose and 31% glucose, while table sugar is one bonded 50/50 molecule. That ratio explains the sweeter taste, the thick texture and why some honeys turn grainy while others stay runny for years.

3. 3.The healthy substances in honey are only traces, so eating it brings no benefit.

   SPLIT

   Split verdict. The “only traces” part is confirmed: 5–50 mg of polyphenols per 100 g and 1–3% of daily vitamins. The “no benefit” part is an evidence gap — antioxidants do rise in the blood, but only at doses around 100 g a day. At a normal spoonful, no trial shows a benefit.

4. 4.Stomach acid destroys everything in honey the moment you swallow it.

   BUSTED

   Busted: polyphenols survive gastric acid fine — lab digestion found 78–112% still available, and human trials measured 7% more antioxidants in the blood after honey. Only the enzymes break down, and their job (making germ-killing peroxide) was never meant to happen inside you anyway.

5. 5.Honey is a real antimicrobial — it works like a disinfectant.

   CONFIRMED

   Confirmed, with a caveat: in the lab, honey kills MRSA, VRE and resistant Pseudomonas through several mechanisms at once, and it genuinely helps burns and cough. But it is a slow, high-concentration growth inhibitor — hours to kill, not seconds — and it works on your skin and in your mouth, not inside your body.

What a jar of honey actually is

Take 100 grams of honey: about 82 grams is sugar — 38 grams fructose, 31 grams glucose, plus a little maltose and sucrose. About 17 grams is water, and so little that bacteria cannot grow in it: honey basically cannot spoil. Everything else together — acids, minerals, polyphenols, enzymes, traces of vitamins — is 1 to 2 grams. Table sugar? 100 grams of sugar, full stop.

That tiny extra fraction is why honey tastes about 1.2 to 1.5 times sweeter than sugar per gram, and why high-glucose honeys turn thick and grainy while high-fructose ones stay runny for years. One surprise: the glycemic index of honey is not one number — it ranges from 32 to 87 depending on the flowers. And the rule-makers treat honey as sugar, full stop: the WHO counts it as free sugar, the FDA as added sugar, and the EU has approved exactly zero health claims for it.

Your body: honey vs sugar

The cleanest experiment is Raatz 2015: 55 adults spent separate periods getting 50 grams of carbohydrate a day as honey, table sugar or high-fructose corn syrup. The result: blood sugar, insulin, blood fats, weight and blood pressure were all identical. All three raised triglycerides. In the best direct comparison, your body cannot tell them apart.

But dose is the real story. A big 2025 umbrella review of 69 trials found: up to about 10 grams a day (two teaspoons) there may be a small benefit. From 20 grams a day — one tablespoon — it tips the other way: fasting blood sugar rises, blood pressure creeps up, triglycerides climb and inflammation markers go up. The honest rule of thumb: a teaspoon is fine, a tablespoon counts as candy.

Where honey is real medicine: on you, not in you

Honey attacks germs in five ways at once: it squeezes them dry, its acids keep the pH too low to grow, dilution switches on a slow-release peroxide, manuka honey adds methylglyoxal, and bees put a bacteria-fighting peptide (defensin-1) in it. In the lab, 10–20% honey kills MRSA and other superbugs — and so far, no bacterium has become resistant to honey.

The strongest clinical result: partial-thickness burns. A Cochrane review of 26 trials (3,011 people) found honey dressings heal burns about 4.7 days faster than standard dressings. Honey also genuinely calms a child’s night-time cough — about as well as common cough syrup — which is why health authorities list it as self-care for children over one. But the largest leg-ulcer trial (368 people) found no benefit, and a honey “disinfectant” is overpromising: it takes hours, not seconds.

Manuka reality check: its special chemistry is real, and its wound evidence is the best of all honeys. Eaten, though, the magic mostly does not reach you — in the only human trial against stomach bacteria, all 12 patients stayed infected. Then look at the shelf: about 1,700 tonnes of genuine manuka are produced in New Zealand each year, while roughly 10,000 tonnes are sold worldwide as “manuka”. Eaten manuka is the most expensive sugar-water in the supermarket.
