Honey: the strongest result is a wound dressing in clinical care

Honey behaves in the body like the sugar it is, and one trial tested exactly that. Fifty grams of carbohydrate a day from honey, from table sugar or from high-fructose corn syrup, each for two weeks in 55 adults, produced the same effect on glucose, on insulin, on HOMA-IR and on the areas under the glucose and insulin curves. Triglycerides rose on all three. The bigger pooling, 69 randomised trials and 3 544 people, found that 10 g of honey a day may lower HbA1c while moving systolic blood pressure, a liver enzyme, triglycerides, fasting glucose and C-reactive protein the wrong way. Systolic pressure rose 0.09 mm Hg for every gram of honey a day, on a straight line. The best evidence on this page is about honey you do not eat. Across 12 studies and 1 236 patients, honey-based dressings beat povidone iodine dressings on healing time, on length of hospital stay and on pain. Read the setting as carefully as the result. These were dressings used as wound care, with time in hospital among the things counted, so none of it is an instruction for a jar and a burn at home.

The numbers, per 100 g

What a real portion looks like

• Each gram of honey a day adds about a tenth of a millimetre of mercury to systolic pressure, and the line is straight. — the 69 pooled randomised controlled trials (n = 3544) Evidence A source
  Systolic pressure rose linearly by 0.09 mm Hg per gram of honey a day (95% CI 0.03 to 0.14); the effect on aspartate transaminase was non-linear, peaking at 25 g a day (+16.7 IU/L, 95% CI 4.22 to 29.3); fasting glucose rose at 20 g a day (+3.81 mg/dL) but fell at 75 g or more (-4.41 mg/dL); the largest haemoglobin A1c reduction came at 10 g a day (-0.37, 95% CI -0.56 to -0.18) and faded at 50 g or more

What your body absorbs

• Honey is not fully absorbed, and in a tenth of a jar's worth about ten grams of it never gets taken up. — 20 healthy volunteers, 13 men and 7 women, mean age 35.9 (n = 20) Evidence B source
  Breath hydrogen rose 30 ppm after 100 g honey, 20 ppm after 50 g and 4 ppm after the glucose-fructose mixture; estimated malabsorbed carbohydrate was 10.3 g, 5.9 g and 0.5 g respectively (P < 0.001); within 10 hours six of twenty reported loose stools after 100 g honey, three after 50 g and none after the mixture (P < 0.03)

What it does to your health

• Two weeks of honey did the same to blood sugar, blood fats and inflammation as the same amount of table sugar or corn syrup. — 28 adults with normal glucose tolerance (mean age 38.9) and 27 with impaired glucose tolerance (mean age 52.1) (n = 55) Evidence B source
  Glucose, insulin, HOMA-IR and the areas under the glucose and insulin curves did not differ between the three sweeteners; body weight was unchanged; triglycerides rose significantly on all three; high sensitivity C-reactive protein rose on all three in the impaired tolerance group; diastolic pressure fell across all treatments

Safety, limits and interactions

• Pooling sixty-nine trials, ten grams of honey a day nudged long-term blood sugar down and five other markers the wrong way. — 69 randomised controlled trials with 3 544 participants (n = 3544) Evidence A source
  10 g of honey a day may lower haemoglobin A1c while adversely affecting systolic blood pressure, aspartate transaminase, triglycerides, fasting blood glucose and high sensitivity C-reactive protein; royal jelly and propolis showed dose-dependent benefits across the same panel
• The harms recorded for honey in drug-safety databases are infant botulism and grayanotoxin poisoning, not anything metabolic. — reported adverse events across the named databases, not a defined cohort Evidence C source
  Honey was linked to infant botulism and to grayanotoxin poisoning; bee venom to anaphylaxis and deaths; propolis to contact dermatitis and systemic reactions; royal jelly to severe asthma attacks; pollen supplements to adulteration with pharmaceuticals; beeswax to allergy; allergic responses were the most common event type overall, especially in atopic people
• No honey at all before a baby's first birthday, and that includes a taste on a pacifier. — children younger than 12 months Evidence E source
  The page states that honey given before 12 months may cause botulism and instructs that honey not be added to a baby's food, water, infant formula or pacifier; it names no exception for pasteurised honey or for honey baked into other foods

What people believe that the data does not support

• Even soothing for the throat is a claim Europe would not let a honey jar make. — — Evidence E source
  The entry carries the status Non-authorised; eight register entries name honey or honeycomb and all eight are refused, covering digestion, flavonoids, antioxidant capacity, heart function, remineralisation, natural defences and the throat; authorised honey claims in the EU number zero
• The digestive claim was refused too, which is awkward next to the trial showing honey loosens the bowel. — — Evidence E source
  The entry carries the status Non-authorised
• American regulation files contains honey with made with real butter, as a value claim rather than a nutrition claim. — — Evidence E source
  The regulation lists contains honey alongside made with real butter and made with whole fruit as claims about the presence of an ingredient perceived to add value to the product, and so outside the nutrient content claim rules; the restriction it then adds applies to vitamin and mineral supplements not in conventional food form

What is still unknown

• As a wound dressing honey beat povidone iodine on healing time, hospital stay and pain. — 12 studies with 1 236 participants, mean age 40.7, treated with honey-based wound dressings against povidone iodine dressings as wound care, with length of hospital stay among the pooled outcomes (n = 1236) Evidence A source
  Hedge's g of -0.81 for mean healing duration, -3.1 for length of hospital stay and -1.2 for pain score in favour of honey-based dressings; the authors grade this as level 1b evidence

The bottom line

No honey before a baby's first birthday. The CDC names no exception for pasteurised honey, for honey baked into something else, or for a taste on a pacifier, and the reason is infant botulism. That is the firmest instruction on this page, and following it costs a parent nothing. For adults, honey is a sweetener, so use it because you like the taste and count it the way you would count sugar. The dose-response curve is unflattering at the amounts people actually eat: fasting glucose rose at 20 g a day, the liver enzyme peaked at 25 g a day, and the HbA1c benefit was largest at 10 g and faded above 50 g. One thing rarely mentioned is that honey is not fully absorbed. After 100 g, an estimated 10.3 g of carbohydrate went unabsorbed and 6 of 20 healthy volunteers had loose stools within ten hours. Half that dose left 5.9 g unabsorbed and gave 3 of 20 the same trouble. The wound result needs the same care as the baby rule, and for the opposite reason. It was measured on dressings against povidone iodine dressings in wound care, and it says nothing about honey from a jar on a cut at home. The two things this page knows about honey sit oddly together. It is the better dressing in that comparison, and it is also the food carrying the spores behind infant botulism, which survive pasteurisation and ordinary baking. Honey on a wound is a treatment somebody else supervises. Alongside infant botulism, the other harm recorded in the drug-safety databases is grayanotoxin poisoning from certain honeys. Nothing metabolic appears there. Europe has authorised zero health claims for honey and refused all eight submitted, including soothing for the throat and helping the digestive system, which sits awkwardly next to the trial showing honey loosens the bowel. In the United States, contains honey is filed beside made with real butter as a claim about an ingredient people think adds value. That is a fair description of what the word does on a label.
