The reason is that after any food is eaten in the stomach, it will be digested into carbohydrates or various amino acids, and finally contribute to your blood sugar.
All foods have a glycemic index, but no hypoglycemia index. Foods with high GI will make your blood sugar rise unnaturally and quickly in a short time, while foods with low GI may only make your blood sugar rise slowly and normally, and will not have much impact on your body.
Fruit is no exception. Every kind of fruit has GI. Fruits with a GI value over 70 belong to high GI fruits, while high GI fruits usually have low water-soluble dietary fiber content and are sweet to eat, but have no dietary fiber. Watermelon, mango, cantaloupe, pineapple, durian, litchi and longan are all high GI fruits.
However, some fruits with low sugar content, such as apples, strawberries, pears, guavas, peaches and oranges, will not lead to a rapid increase in patients' blood sugar after eating these low-sugar fruits.
Of course, there are also a few fruits that will accelerate the secretion of insulin in the body after entering the human body, making people feel a little hypoglycemia. Many people mistakenly think that these fruits have hypoglycemic effect, but in fact, this fruit has a very high sugar content and belongs to high GI fruits, such as mango. It is a high-sugar fruit, but people with high blood sugar can't feel the rapid rise of blood sugar after eating it. It's just that mango makes you secrete more insulin, and the harm to your body has not changed.
We should recognize the fact that any fruit will be converted into glucose after it is eaten in the body, and it is just a matter of drinking more and less. No fruit can take the place of medicine. People with high blood sugar try to eat fruits with low GI.
People with high blood sugar should pay attention to some matters when eating fruit.
First, measure blood sugar.
People with high blood sugar should measure and change their blood sugar before eating food, and of course, before eating fruit.
If the fasting blood glucose is below 7.8 mmol/L, the 2-hour postprandial blood glucose is below 10 mmol/L, and the glycosylated hemoglobin is below 7.5%, you can eat fruit in this case. If the data greatly exceeds this, you'd better bear it.
Second, eat 2 hours after meals.
People with high blood sugar will definitely increase their blood sugar after eating it, so eating fruit at this time will further increase their blood sugar. Therefore, if you want to eat fruit, it is best to eat it 2 hours after meals to avoid the peak of blood sugar.
Third, don't drink juice.
Fruit juice is thin, and the dietary fiber in it has been destroyed, which can be easily converted into sugar, causing a rapid blood sugar response. Fresh and complete fruits contain a lot of dietary fiber, which can delay the response of blood sugar to some extent.
