Maltose that can't be eaten is most easily converted into glucose, which is more easily absorbed than white sugar. Faced with a wide variety of sugar-free foods on the market, diabetics are dazzled. Does sugar-free food have sugar? Can hypoglycemic food reduce blood sugar? Experts believe that sugar-free food refers to sweet food without sugar, that is, sucrose (cane sugar and beet sugar) and starch sugar (glucose, maltose and fructose), but sugar-free food must contain sugar substitutes with sugar properties, such as sugar alcohols (including xylitol, sorbitol, maltitol, mannitol, etc.), rather than sweet food produced with high-magnification sweeteners such as saccharin. At present, the sugar substitutes that have been approved to be included in the hygienic standard in China are maltitol, sorbitol, xylitol and lactitol.
