natural caloric sweeteners is equivalent to table sugar glycemically
In plain terms: Do honey, agave and maple sugar spike blood sugar identically to table sugar?
Part of: • Added sugar
No — they are all caloric sugars with broadly similar impact, but not identical: honey and high-fructose agave measurably produce a lower acute glucose spike than sucrose/glucose.

How the studies fall
What the evidence shows
They are all caloric sugars with broadly similar effects, but not identical. Glycaemic index tracks fructose content: five of eight German honeys measured low-GI, below 55, and a Barhi date syrup measured GI 55, low, with a medium glycaemic load of 11 per portion. The index differences are modest; a low GI says nothing about calories or overall health effect, and load depends on portion size.

| Source | Grade | Stance | Quality | Finding |
|---|---|---|---|---|
| Camps SG, Koh HR, Wang NX, Henry CJ 2020 · Nutrition | RCT | contradicts | moderate | Crossover challenge: fructose-containing meals produced a lower glucose (and different insulin/TG) response than glucose-matched meals — fructose-rich sweeteners (agave) are not glycemically identical. |
| Deibert P, König D, Kloock B, Groenefeld M, Berg A 2010 · Eur J Clin Nutr | RCT | contradicts | moderate | In a crossover of 8 German honeys, 5 had GI under 55 tracking fructose content, showing honeys are frequently low-GI and not equivalent to table sugar. |
| Olagunju AI 2019 · Prev Nutr Food Sci | observational | contradicts | low | Multigrain breads made with date palm fruit sugar (DPFS) replacing sucrose showed low GI, especially at >20% whole-wheat substitution plus 100% DPFS, versus intermediate GI (65.61) for the sucrose-based control. |
| Ischayek JI, Kern M 2006 · J Am Diet Assoc | RCT | mixed | moderate | Four US honeys had GI ~69-74 (below glucose); honey is sugar-like but not glycemically identical to glucose. |
| Julai K, Sridonpai P, Ngampeerapong C, Tongdonpo K, Suttisansanee U, Kriengsinyos W, On-Nom N, Tangsuphoom N 2023 · Foods | observational | contradicts | moderate | Date syrup (Barhi) produced via enzyme-assisted extraction and open heating measured in vivo GI = 55 (medium GL = 11), classified as low glycemic index. |
| Naveed H, Sultan W, Awan KA, Imtiaz A, Yaqoob S, Al-Asmari F, Faraz A, Qian JY, Sharma A, Mugabi R, Alotaibi SS, Nayik GA 2024 · Food Chem X | observational | contradicts | low | Review reports cereal-based bakery products have GI 55-80 while legume-based products have lower GI 40-50, with legume incorporation lowering GI by up to 25%. |
| Gourdomichali T, Papakonstantinou E 2018 · Eur J Clin Nutr | RCT | contradicts | moderate | Double-blind crossover: several honey varieties produced an attenuated postprandial glycemic response vs glucose in healthy subjects; response varied by fructose/glucose ratio. |
| Ahmad A, Azim MK, Mesaik MA, Khan RA 2008 · J Food Sci | RCT | contradicts | low | Natural honey produced significantly lower plasma glucose rise than isoglucidic D-glucose/simulated honey at all timepoints. |
| Pepin A, Stanhope KL, Imbeault P 2019 · Nutrients | observational | mixed | low | Review: free-sugar composition of caloric sweeteners is broadly similar, but fructose:glucose ratio drives differing acute glycemic and lipid effects — supports similar overall, contradicts identical spike. |
| Chlup R, Peterson K, Zapletalová J, Kudlová P, Seckar P 2010 · Diabetes Technol Ther | observational | mixed | low | Extended CGM glycemic profiling showed GI varies substantially by composition and measurement window, undercutting "spike identically. |
Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
