Patients are not recommended to eat tofu brain when their blood sugar is high. Although the types of food are not strictly limited in diabetes, but mainly the total calories of food are controlled, certain foods that contain too many calories or have a greater impact on blood sugar should be limited, and tofu brain is one of these. Although tofu brains, which are mainly soy products, do not have a significant impact on blood sugar, the excipients needed in the preparation process are not suitable for diabetics, including the application of gluconolactone in the process of converting beans into tofu brains, which requires most of the application of gluconolactone and may have an impact on blood sugar. The added seasonings, which contain sesame oil, sesame sauce, soy sauce, and various seasonings containing sugar, can also have an effect on blood sugar. This is the main reason why many patients experience fluctuations in blood sugar after eating tofu brain, so patients are generally not recommended to eat tofu brain when their blood sugar is high, and even if they do, they should pay attention to monitoring their blood sugar after consumption.
