It is inappropriate for diabetic patients to avoid fruits completely, because fruits contain a lot of vitamins, fiber and minerals, which are beneficial to diabetic patients. Fruits contain sugars such as glucose, fructose and sucrose, of which fructose does not need insulin to participate in the metabolism, so diabetics should not reject fruits after their blood sugar has been controlled. Moreover, the amount of sugar in fruits varies, and the condition of diabetes is not the same, so it should not be regarded as the same, to distinguish the situation: watermelon contains 4% sugar, pears contain 12% sugar, bananas for 20%. Although watermelon contains less sugar, but eat on 500 grams, it is equivalent to banana 100 grams, pear 170 grams (various fruits of the energy exchange in my old hospital clinic hanging in the office), so the amount of food should not be too much. Fruit eating method should also be careful, do not eat immediately after the meal, can eat between meals or before going to bed. It is best to eat on a trial basis, that is, 2 hours after eating to measure blood sugar. If there is a significant increase in blood sugar, the amount should be reduced. Under what circumstances can I eat fruit? Diabetic patients can eat appropriately when their condition is under stable control. Generally speaking, patients with fasting blood sugar below 7.8 mmol/l (140 mg/dl), blood sugar below 10 mmol/l (180 mg/dl) 2 hours after meal, and glycosylated hemoglobin below 7.5% with stable condition can choose fruits with lower sugar content. For some patients with high blood sugar and unstable condition can only use vegetables and fruits with sugar content below 5%, like strawberries, tomatoes, cucumbers, etc. How much fruit can diabetic patients eat every day? The amount of fruit that diabetic patients should eat every day is also to be considered. In general, if the blood sugar control of diabetic patients is relatively stable, they can eat about 150 grams of fresh fruits with low sugar content every day. If the amount of fresh fruit eaten per day reaches 200-250 grams, 25 grams (half a tael) should be subtracted from the main food for the whole day to avoid exceeding the total energy limit for the whole day and causing blood sugar to rise.
