Are there certain foods that can cause sudden changes in my blood glucose levels?

Yes, certain foods and drinks can cause sudden changes in your blood glucose levels. High-carbohydrate foods, such as bread, pasta, rice, and sugary snacks or beverages, can cause a rapid rise in blood glucose. In addition, processed foods high in refined carbohydrates and added sugars can spike blood glucose levels. Alcohol can also cause blood sugar fluctuations, it can cause your blood glucose to either rise or fall, depending on how much you consume and if you eat at the same time. It's important to monitor your blood glucose levels and understand how different foods and drinks affect your individual readings. Always remember to balance carbohydrate intake with protein and healthy fats for more steady blood glucose levels.
