Before the discovery of sugar, only honey was used as a sweetener. The energetic action is due to the particular composition of honey: glucose, fructose, water and pollen. Fructose, in particular, renders the honey sweetener than refined sugar and at the same time a more lasting source of energy and fuel for the muscles: this is why consumption of honey is encouraged to athletes before physical activity. Honey has also a real antibacterial action due to an enzyme that activates during dilution. Other benefits are the probiotic activity that is useful for the functioning of the intestinal microbial flora, the antioxidant activity, thanks to the presence of flavonoids, the anti-inflammatory activity and a glycemic index lower than sugar.
