People with diabetes should try not to eat thin rice because it has a high glycemic index. The glycemic index of a food refers to the magnitude and speed of the increase in blood sugar caused by the food entering the body. The greater the increase in blood sugar and the faster the increase, the higher the glycemic index of the food. In the process of boiling, the starch inside the grain expands with water and the internal structure of the starch changes, which is called starch pasting. After pasteurization, the food is easily broken down into glucose after entering the digestive tract, causing a rapid rise in blood sugar within a short period of time, which means that the glycemic index of thin rice is high and can cause large fluctuations in blood sugar. Therefore, diabetic patients should not eat thin rice, including all kinds of food boiled thin rice, such as rice thin rice, millet thin rice, corn thin rice, noodle soup and so on. In addition, do not drink the paste made from yam powder and lotus root powder.
