Diabetic patients can eat wheat flour. Pasta made from wheat flour mainly includes steamed buns, buns and dumplings, which are some of the more commonly eaten staple foods. Because the starch content of flour is relatively high, starch is converted into glucose for absorption in the body, so if more pasta is eaten, it has a greater impact on blood sugar. Therefore, diabetic patients should strictly control the amount when eating staple foods, especially when eating steamed buns, and should not eat too much. Dumplings and buns contain relatively less pasta and more vegetables, which will have less impact on blood sugar. Diabetic patients should pay attention to monitoring blood sugar two hours after eating the main food.
