Loquat raises blood sugar. Blood glucose refers to the amount of glucose in the blood. Carbohydrates in food can enter the blood circulation after digestion and decomposition, thus affecting the blood glucose level. Food Glycemic Index (GI), referred to as the glycemic index, can be used to measure the impact of eating different types of food on the speed and magnitude of postprandial glucose elevation in the human body, reflecting the degree of food-induced elevation of blood glucose in the human body indicators. Generally, GI is higher than 70 for high glycemic index, 70~55 for medium glycemic index, and less than or equal to 55 for low glycemic index. Every 100 grams of loquat contains about 9.3 grams of carbohydrates, belonging to the low glycemic index of the fruit, low glycemic index food on blood sugar impact is small. Loquat glycemic index is not high, it is recommended that diabetic patients can be consumed in moderation, such as discomfort, should seek medical attention.
