Eating large quantities of cherries can cause a rise in blood sugar, but eating cherries appropriately does not cause a sharp rise in blood sugar. Cherries contain a certain amount of sugar, so after eating cherries, blood sugar will also rise to a corresponding degree. However, the glycemic index of cherries is not high, which is 22, belonging to low GI food. The glycemic index can reflect the ability and speed of food to raise blood sugar compared with glucose, the lower the glycemic index of food, the slower the speed of raising blood sugar, so eating cherries in moderation won’t cause a sharp rise in blood sugar. Therefore, in daily life, healthy people or patients with high blood sugar can choose fruits with lower glycemic index, such as apples, grapefruit, etc., which can help maintain stable blood sugar. Seek medical advice if you notice abnormal blood sugar levels.
