The objective of this open-label, randomized, crossover clinical trial is to determine the effect of consuming 15 ml of organic apple cider vinegar on glycemic variability, measured by the coefficient of variation of glucose, in adults with type 2 diabetes mellitus. The main question this study seeks to answer is: What is the effect of consuming 15 ml of organic apple cider vinegar every 12 hours for a period of 2 weeks on the coefficient of variation of glucose in adults aged 18 to 60 years with type 2 diabetes mellitus, compared to consuming 250 ml of natural water? The researchers will compare the consumption of organic apple cider vinegar with natural water to evaluate whether organic apple cider vinegar has an impact on glycemic variability. Participants, in a crossover design, will use a continuous glucose monitor throughout the study. In one phase, they will consume 15 ml of apple cider vinegar before breakfast and before dinner for a period of 14 days, and in the other phase, they will consume 250 ml of natural water for the same period, with a washout period between both phases. Glucose data obtained through the continuous glucose monitor will be used to calculate the coefficient of variation as the primary measure of glycemic variability.
