Maltitol is difficult to digest in the body. Maltitol, also known as hydrogenated maltose, is a new type of sweetener widely used in the processing of sugar-flavored foods. Maltitol is about 0.9 times sweeter than sucrose, which is sweeter, but it is almost completely not absorbed and broken down by saliva, small intestinal membrane enzymes, and gastric juices. After maltitol is ingested into the body, about 10% will be broken down and absorbed in the small intestine, and the remaining 90% will be broken down by the action of colon bacteria. Therefore, maltitol is a sweetener that can be consumed by diabetic patients, and because it is difficult to absorb, it has little or no effect on the blood glucose level in the body. However, maltitol must be taken into account when calculating a diabetic patient’s allowable daily intake of sugar. Even though maltitol is hardly absorbed by the body, it should not be ingested without limit, and diarrhea can easily be caused by ingesting maltitol in large quantities. If maltitol consumption leads to uncomfortable symptoms in the body, you should seek medical treatment promptly to avoid delaying your condition.
