> improves hygienic conditions by increasing production of GOX - H2O2 (Hydrogen peroxide)


Maybe others on the list have a more nuanced understanding of chemistry,  but I can't see where the cited study supports the above claim.  


From the study: 

> The quality of food for overwintering success and bee fitness is essential; it also impacts resistance to diseases [35]. According to the results of a two-year field trial, the best fitness parameters and the lowest prevalence and intensity of nosematosis, a common bee disease, were found in colonies fed with honey compared to other substances (sucrose, inverted sugar and wheat starch syrup) [35].


> Honey provides reasonable protection from bacterial infections and, as shown in this study, possesses significantly higher antibacterial potential than supplemental syrups after their processing in the colony.
