Myths vs facts: Glukose and blood sugar

The provided knowledge contexts contain no specific information about myths versus facts regarding glucose and blood sugar. Therefore, I cannot derive an evidence-based answer from these sources. In general, many myths circulate, e.g., that sugar directly causes diabetes or that fruit sugar is harmless. In reality, type 2 diabetes development is multifactorial (obesity, genetics, lifestyle). The glycemic index of foods is only a rough guide and varies individually. Without relevant studies or guidelines from the context, I must emphasize that these statements are not supported by the data provided here. For a well-founded clarification of glucose myths, specific sources would be needed, which are absent. Hence, the evidence level from this context is unclear.
