Does heating honey above 160 degrees affect its healthful benefits?
A. Possibly. Heating honey may increase the amount of methylglyoxal (MGO) found in honey. MGO is known to be dangerous to individuals who have glucose intolerance or diabetes. MGO may even affect insulin signaling which may be a cause of diabetes. Honey that contains MGO should not be ingested. It is however safe for topical use as an antibiotic.
