How can one respond to someone who claims that honey is not beneficial for diabetics and may cause them to contract it?

Allah Almighty stated that honey contains "a cure for people," and this indefiniteness implies that it is a cure for some ailments, not all. As for some people's objection that honey may cause diabetes, the answer to this is multifaceted: Firstly, medical experts believe that natural honey is beneficial for diabetes, and that overconsumption is what is harmful. Secondly, known medications, if not taken in specific proportions and under the supervision of specialists, can harm the patient. Thirdly, many types of honey available are adulterated and may be mixed with sugar, which causes harm, especially to diabetic patients. It is then thought that the harm comes from the honey itself, while in reality, it is from the substances added to it.
