Sugar-free cereals are suitable for people with diabetes, but it is important to control the total number of calories consumed per day. Cereals are high in dietary fiber and lower in carbohydrates than refined rice and flour. Cereal is rich in crude fiber, which can increase the feeling of satiety for diabetic patients and delay the intestinal absorption of sugar. Therefore, diabetic patients can consume sugar-free cereals in moderation within a reasonable range of total daily calories. In addition, diabetic patients should choose raw cereals pressed directly from oats, and not buy directly brewed refined cereals. It is recommended that cereals should not be cooked for too long to avoid excessive sugar release. Meanwhile, sugar-free cereals are mainly composed of starch, so diabetics need to reduce the amount of staple food after consuming cereals. Diabetic patients can consult their professional doctors for a reasonable diet plan.
