Xylitol is a natural sweetener extracted from birch, oak, corn cob, sugarcane bagasse and other plant materials. High blood sugar may be caused by having diabetes or seen in people with reduced glucose tolerance. Usually, people with high blood sugar can eat foods containing xylitol in small amounts without worrying about how their bodies will be affected. As xylitol is an intermediate in human sugar metabolism, it can be absorbed and used by tissues through cell membranes to promote liver glycogen synthesis without insulin promotion in the absence of insulin affecting sugar metabolism in the body, and will not cause an increase in blood sugar. Therefore, people with high blood sugar can eat foods containing xylitol in small amounts, including cakes made of xylitol. In the daily raw lake, people with high blood sugar need to have overall control over the calories they eat each day, including carbohydrates, fats, proteins and water. Even though xylitol produces very few calories, it does produce calories. So you also need to count calories when eating foods containing xylitol and not eat too much to avoid going over the limit. In addition, excessive consumption of xylitol can easily lead to discomfort in the gastrointestinal tract of patients, such as nausea, vomiting, bloating and acid reflux. In addition to foods made from xylitol, people with high blood sugar can also eat foods containing aspartame and stevia, both of which are sweeteners and contain less energy. In addition, you can also eat sweet potatoes in moderation, because the carbohydrates contained in them are much less than ordinary rice and flour, while the dietary fiber is rich, low glycemic index, more beneficial to blood sugar control.
