Honey is a natural sweetener that regulatory agencies classify as an “added sugar” the moment you stir it into your tea or drizzle it over yogurt. This dual identity confuses people for good reason: honey comes from bees, not a factory, yet the USDA treats it the same as granulated sugar on food labels. The distinction turns on context rather than chemistry, and the answer matters more for how you read a nutrition label than for what honey actually does in your body.
Why Honey Gets Called Both Things
The term “natural sweetener” has no strict legal definition. It generally means a sweet substance found in nature without heavy industrial processing. By that standard, honey qualifies easily. Bees produce it from flower nectar, and it arrives on your shelf as a recognizable food that humans have eaten for tens of thousands of years.
“Added sugar,” on the other hand, is a regulatory category. In the United States, the USDA defines added sugars as any sugars or syrups added to foods during preparation or processing. Honey, maple syrup, agave nectar, and table sugar all fall into this bucket when a manufacturer or cook puts them into a product. The USDA’s Food Patterns Equivalents Databases classify honey this way, though they note that honey contains more moisture than granulated sugar and therefore delivers fewer teaspoon equivalents of sugar per 100 grams.1Journal of Food Composition and Analysis. Added sugars: Definition and estimation in the USDA Food Patterns Equivalents Databases In other words, a tablespoon of honey is technically less concentrated than a tablespoon of white sugar, but it still counts the same way on a label.
So the answer depends on which question you’re asking. Is honey natural? Yes. Does it count as “added sugar” when it appears in processed food or your morning coffee? Also yes. The label on a bottle of plain honey sold by itself will show sugars under “Total Sugars” with zero grams listed as “Added Sugars,” because nothing was added to the honey. But a granola bar sweetened with honey will list those same sugars as added.
What Honey Actually Contains
Honey is roughly 80% sugar by weight, with the remaining 20% being mostly water. The dominant sugars are fructose and glucose, in proportions that vary depending on the flower source. Beyond simple sugars, honey contains small amounts of proteins, amino acids, enzymes, organic acids, vitamins, minerals, and phenolic compounds.2PubMed. Honey: Chemical composition, stability and authenticity These minor components are what separate honey from, say, high fructose corn syrup. Both are mostly fructose and glucose, but honey carries a package of bioactive molecules that corn syrup does not.
The phenolic compounds and flavonoids in honey act as antioxidants and have been studied for their effects on inflammation, cell signaling, and oxidative stress.3PubMed Central. Honey as a Potential Natural Antioxidant Medicine: An Insight into Its Molecular Mechanisms of Action These aren’t present in meaningful amounts in refined sugar or most commercial syrups. But it’s worth keeping perspective: the quantities of these compounds in a serving of honey are small. You’d need to eat a lot of honey to get a pharmacologically significant dose of any single antioxidant, and eating that much honey means eating a lot of sugar in the process.
Blood Sugar Response Compared to Table Sugar
One of the most commonly repeated claims about honey is that it’s “better for blood sugar” than regular sugar. There is some clinical support for this, though the picture is more complicated than the health-food aisle suggests.
Studies in both healthy volunteers and people with type 1 diabetes have found that honey produces a lower blood sugar spike after eating compared to sucrose or pure glucose.4PubMed. The glycemic and peak incremental indices of honey, sucrose and glucose in patients with type 1 diabetes mellitus: effects on C-peptide level-a pilot study5PubMed. Plasma glucose responses to glucose, sucrose, and honey in patients with diabetes mellitus: an analysis of glycaemic and peak incremental indices The effect is real but modest, and researchers have noted considerable variability from person to person. A review of honey’s metabolic effects found that honey intake can reduce blood sugar levels and improve lipid profiles, with some evidence that it enhances insulin sensitivity.6PubMed Central. A Review on the Protective Effects of Honey against Metabolic Syndrome
In a carefully controlled clinical trial, healthy men given high-fructose diets from either honey or a fructose-glucose mixture showed decreased postprandial blood glucose and insulin levels, consistent with fructose’s low glycemic index. Crucially, the honey diet did not significantly raise fasting triglycerides or worsen liver insulin sensitivity over the study period.7Clinical Nutrition ESPEN. A randomized-controlled clinical trial of high fructose diets from either Robinia honey or free fructose and glucose in healthy normal weight males That last point matters because fructose has a reputation for promoting fatty liver, and the study found that honey at least didn’t make it worse.
A small crossover study comparing honey and sucrose found that honey delayed the ghrelin response (ghrelin is the hormone that signals hunger) and enhanced a satiety hormone called PYY, though actual food intake at the next meal didn’t differ between the two groups.8PubMed. Effect of honey versus sucrose on appetite, appetite-regulating hormones, and postmeal thermogenesis So honey may shift some hormonal signals in a favorable direction, but don’t expect it to dramatically change how much you eat.
Not All Honey Is the Same
Here’s where the conversation gets interesting and where most popular advice falls short. The glycemic index of honey varies substantially depending on where the bees foraged. A clinical trial testing six Greek honey varieties found that fir and chestnut honeys had medium glycemic index values (59 and 66 on the glucose scale), while citrus, heather, pine, and thyme honeys all scored above 70, placing them in the high glycemic index range.9PubMed Central. Short-term effects of six Greek honey varieties on glycemic response: a randomized clinical trial in healthy subjects The differences correlated with sugar composition: honeys with higher fructose-to-glucose ratios and more oligosaccharides tended to produce smaller blood sugar spikes.
A study of three Mexican honey varieties found a similar spread, with glycemic index values ranging from about 66 to 75 depending on the floral source.10PubMed Central. Glycemic and Satiety Response to Three Mexican Honey Varieties The practical takeaway is that a generic statement like “honey has a lower glycemic index than sugar” is only conditionally true. Some honeys do, others rival white bread. If you’re choosing honey specifically for blood sugar management, the floral source matters, and most grocery-store labels won’t tell you enough to make that call.
How Honey Compares to Other Natural Sweeteners
Honey is not the only natural sweetener people reach for when avoiding refined sugar. Maple syrup, agave nectar, molasses, and brown rice syrup all compete for shelf space. A rat study comparing these sweeteners found that maple syrup produced lower peak glucose and insulin responses than honey, and that agave and molasses behaved similarly to maple syrup, while honey triggered higher peak insulin responses.11Journal of Functional Foods. Comparative analysis of maple syrup to other natural sweeteners and evaluation of their metabolic responses in healthy rats This is one animal study, so translate those results cautiously, but it’s a useful reminder that “natural” doesn’t automatically mean “metabolically gentle,” and honey isn’t necessarily the gentlest option.
A comprehensive review found that beneficial effects of honey intake have been observed for cardiovascular and metabolic risk factors, particularly when honey replaces other sweeteners rather than being piled on top of an existing diet.12PubMed Central. A Comprehensive Review of the Effect of Honey on Human Health That “replaces” part is critical. Adding honey on top of your normal sugar intake gives you more total sugar. Swapping it in for some of the refined sugar you already eat is where any potential benefit appears.
The Sweetness Perception Trick
One underappreciated advantage of honey over plain sugar is that you may not need as much of it. A sensory study measuring perceived sweetness found that honey’s aroma volatiles significantly boosted its sweetness intensity. At a given concentration by weight, honey and sugar tasted equally sweet when aroma was present. But remove the aroma and honey tasted less sweet, meaning the aromatic compounds were doing real perceptual work. In a 100 g/L solution, honey’s aromas increased perceived sweetness by 23% to 43% depending on the floral source.13PubMed Central. Quantifying the sweetness intensity and impact of aroma in honey from four floral sources The practical implication: if you use honey in recipes partly for its flavor, you may end up using less total sweetener than you would with plain sugar, simply because it tastes sweeter per gram.
Honey’s Prebiotic Side
Beyond its sugars, honey contains non-digestible carbohydrates in the form of oligosaccharides. These are short-chain sugars that pass through your stomach and small intestine mostly intact, arriving in your colon where gut bacteria ferment them. There is growing evidence from lab studies, animal models, and small human trials that some honeys have prebiotic activity, meaning they promote the growth of beneficial gut microbes.14PubMed Central. The Potential of Honey as a Prebiotic Food to Re-engineer the Gut Microbiome Toward a Healthy State In lab experiments, honey oligosaccharides boosted populations of bifidobacteria and lactobacilli, though not as effectively as a commercial prebiotic fiber called fructooligosaccharides.15PubMed. In vitro investigation into the potential prebiotic activity of honey oligosaccharides
This is still an early-stage area of research, and the oligosaccharide content of honey varies widely by type. But it’s one more dimension in which honey isn’t just “sugar with a nicer story.” It contains compounds that refined sugar simply doesn’t.
What Happens When Honey Gets Heated
If you bake with honey or buy heavily processed honey, some of the compounds that distinguish it from plain sugar may be degraded. Thermal processing increases levels of hydroxymethylfurfural (HMF), a marker of heat damage, and reduces the activity of enzymes like diastase, both of which are used as quality indicators.16Journal of Food Process Engineering. Exploring the Impact of Thermal Processing on the Quality Attributes of Honey: A Comprehensive Review17PubMed. Conventional and emergent technologies for honey processing: A perspective on microbiological safety, bioactivity, and quality
That said, not all heat is equally destructive. A study comparing raw, liquefied, and pasteurized honeys found that gentle liquefaction (lower temperature, shorter time) didn’t significantly reduce antioxidant activity compared to raw honey, but full pasteurization did cause meaningful losses.18Food Science and Technology. Effect of heat treatment for liquefaction and pasteurization on antioxidant activity and phenolic compounds of Astragalus and sunflower-cornflower honeys So if you value honey’s bioactive properties, raw or minimally processed honey retains more of them. Honey baked into a cake at high temperatures for 30 minutes is probably closer to flavored sugar than to a functional food.
Honey and Your Teeth
Given that honey is mostly sugar, you’d expect it to be just as bad for your teeth as a spoonful of table sugar. The reality is a bit more nuanced. A study of orthodontic patients found that while honey did cause an initial pH drop in the mouth (acid is what causes tooth decay), the pH recovered within 10 to 20 minutes and never fell below the critical threshold for enamel damage. Sucrose, by contrast, dropped the mouth’s pH below that danger line and took 30 minutes to recover. Bacterial counts were also significantly lower in the honey group, and honey inhibited the growth of oral pathogens more effectively than the studied antibiotics.19PubMed Central. Effect of honey in preventing gingivitis and dental caries in patients undergoing orthodontic treatment
Lab studies have confirmed honey’s antibacterial effects against Streptococcus mutans, the primary bacterium responsible for tooth decay, though evidence for its antibiofilm effects is still limited to a handful of studies.20PubMed Central. Antibacterial and Antibiofilm Effect of Honey in the Prevention of Dental Caries: A Recent Perspective None of this means you should rinse your mouth with honey. But honey appears to be less damaging to teeth than an equivalent amount of table sugar, partly because its antibacterial properties offset some of the harm its sugars would otherwise cause.
The Fructose Concern
Because honey is high in fructose, some health writers have raised concerns that it could promote fatty liver disease or raise uric acid levels, much like high-fructose corn syrup has been accused of doing. An animal study using acacia honey found that it could induce elevated uric acid, increased triglycerides, and fatty liver in rats in a dose-dependent manner.21Natural Product Communications. Effect of Acacia Honey on Serum Uric Acid Level and Liver Injury in Rats That sounds alarming, but the doses in that study were high relative to body weight, and rat metabolism doesn’t translate perfectly to humans.
In the controlled human trial mentioned earlier, healthy men consuming honey-based high-fructose diets did not show the increases in triglycerides or impaired liver insulin sensitivity that other fructose-feeding studies have reported.7Clinical Nutrition ESPEN. A randomized-controlled clinical trial of high fructose diets from either Robinia honey or free fructose and glucose in healthy normal weight males Rat studies looking at honey’s effects on insulin resistance pathways have found that, unlike equivalent amounts of sugar solution, honey suppressed insulin resistance markers and improved inflammatory and lipid profiles.22PubMed. Alternative to Sugar, Honey Does Not Provoke Insulin Resistance in Rats Based on Lipid Profiles, Inflammation, and IRS/PI3K/AKT Signaling Pathways Modulation The researchers attributed this to honey’s phenolic compounds and oligosaccharides rather than to the sugars themselves.
The emerging picture is that honey’s fructose doesn’t behave identically to the same amount of fructose delivered as corn syrup or pure fructose. The other compounds in honey appear to modify the metabolic response. But this should not be interpreted as a green light to consume unlimited honey. At sufficiently high doses, the fructose load will overwhelm any protective effects from trace bioactive compounds.
The Adulteration Problem
One practical wrinkle that doesn’t get enough attention: a meaningful fraction of commercially sold honey isn’t pure honey. Adulteration with cheaper syrups like high fructose corn syrup, maltose syrup, rice syrup, and agave syrup is a known problem worldwide. Researchers have developed various detection techniques, including Raman spectroscopy, which can identify samples adulterated with corn syrup or maltose syrup with accuracy rates above 90%.23Journal of Food Composition and Analysis. Detection of honey adulteration by high fructose corn syrup and maltose syrup using Raman spectroscopy HPLC-based methods have been applied to inspect over 100 commercial honeys for starch syrup adulteration.24PubMed. Detection of honey adulteration with starch syrup by high performance liquid chromatography Rheological analysis can also catch adulteration: authentic honey has a much higher viscosity than honey diluted with maple or rice syrup.25Scientific Reports. Rheological behavior of honey adulterated with agave, maple, corn, rice and inverted sugar syrups
This matters because if you’re buying honey for its bioactive compounds and lower glycemic response, adulterated honey may just be expensive corn syrup. Buying from local beekeepers or looking for lab-tested certifications can help, though no consumer-facing test is foolproof.
Safety for Infants
One safety concern that applies regardless of how natural honey is: it should never be given to babies under one year old. Honey is the only well-established food source linked to infant botulism, a rare but serious illness caused by spores of Clostridium botulinum.26PubMed Central. Infant Botulism: In Search of Clostridium botulinum Spores An infant’s gut is too immature to prevent these spores from colonizing and producing toxin. In at least one documented case in the UK, the bacterium was successfully isolated from both the patient and the jar of honey that was the suspected source.27PubMed Central. The hazards of honey: infantile botulism The CDC, the American Academy of Pediatrics, and the National Honey Board all recommend that honey not be given to infants younger than 12 months.28EDIS. Infant Botulism and Honey After age one, the risk drops sharply because the gut microbiome has matured enough to handle stray spores.
Honey in the Deep History of Human Diets
Part of the reason honey occupies such a warm cultural spot is that humans have been eating it for a very long time. A study of forager societies found that virtually all warm-climate hunter-gatherers consume honey, and that the Hadza of Tanzania, one of the most-studied foraging populations, rank honey as their favorite food. Honey accounts for a substantial portion of daily calories in the Hadza diet, especially among men who climb tall baobab trees to raid large hives.29PubMed. Honey, Hadza, hunter-gatherers, and human evolution The researchers argued that honey has likely been part of the hominin diet since the earliest members of our lineage.
A more recent modeling study published in Science proposed that before cooking made starchy foods easily digestible, the sugars in fruit and honey provided glucose for the brain’s high energy demands. The model suggests sugars supplied more than a quarter of dietary energy in ancestral diets, fulfilling the brain’s obligatory glucose requirement.30PubMed. A central role for dietary sugars in human evolution Honey is described as the most energy-dense food found in nature, which helps explain why foragers across cultures prize it so highly. None of this means modern humans should eat honey in ancestral quantities. But it does contextualize why our taste buds and reward circuits respond to honey the way they do: we evolved in environments where finding it was rare and valuable, not environments where it was available in a squeeze bear at every checkout lane.
