It’s the season when a large number of corn is on the market. Corn is a staple food we often eat. There are many varieties of corn on the market, such as old corn, sweet corn, glutinous corn, fruit corn and so on.
The older generation likes to use cornmeal to make porridge, make corn pudding, cornmeal buns, pastry and so on. Many diabetics believe that cornmeal tastes rough to eat, indicating that it is rich in dietary fiber and must be good for blood sugar.
Cornmeal has a rough taste, is it really friendly to blood sugar?
In fact, corn flour is different from corn, and the glycemic index of corn flour can reach about 70. The glycemic index of different varieties of cornmeal is not much different, even the glycemic index of coarse cornmeal porridge can reach 66.
When the glycemic index is greater than 70, it means that this kind of food is not suitable for diabetics, and the glycemic index is less than 55. At that time, diabetic patients can eat it in moderation.
So, cornmeal is not an ideal food for diabetics, especially waxy cornmeal, which can't control blood sugar. In the process of corn flour processing, the dietary fiber is destroyed, which causes the glycemic index of corn flour to be significantly higher than that of whole corn, so people with high blood sugar should eat whole corn.
Old corn, sweet corn or sticky corn, which is more suitable for people with high blood sugar?
In the eyes of many people, old corn is the most unpalatable kind of corn. It is old and hard when cooked directly, which is hard to swallow. But theoretically, old corn is the most suitable type of corn for people with diabetes, followed by sweet corn, and finally waxy corn.
If you really don’t want to eat old corn, you can also choose sweet corn. From the perspective of nutritional value, the protein and vitamin content of sweet corn is 1-2 times higher than that of waxy corn, and the selenium content is 8-10 times higher.
From the glycemic index, waxy corn Corn tastes soft and waxy because of its high content of amylopectin, which is easy to digest and absorb, so it is not good for blood sugar. Although sweet corn has a "sweet" word, its glycemic index is only 55. In general, sweet corn is more suitable for people with high blood sugar than waxy corn.
Finally, I need to remind you that no amount of good food can be overeaten. Diabetics should not eat more than one corn, and corn has a high starch content and should be used as a substitute for the staple food. That is to say, people who usually eat two bowls of rice should consume one corn accordingly. Reduce the rice to a bowl or half a bowl.
