各位朋友：

大家好，现在是“每天健康三分钟”时间，我是道简-心血管康复医生集团的医生赵方慧，今天由我来给大家讲讲糖尿病人怎么吃玉米面。

都说糖尿病人吃粗粮好，那么糖尿病人能不能吃玉米面呢？

事实上，这与玉米面的加工方法和品种有关。新鲜甜玉米的升糖指数约为55，比常吃的米饭、馒头都要低。

但粗玉米面粥升糖指数为66，细玉米面要更高一些，几乎与精制白面、白米差不了太多，因为深度粉碎且长时间熬煮的玉米粥，所含膳食纤维更少，消化吸收更快，升血糖的作用也很快。

黏玉米所含的淀粉比甜玉米更容易消化吸收，因此糯玉米面也比甜玉米面更容易升高血糖。

因此糖尿病患者吃玉米面需要注意以下几点：

一、尽量少吃细玉米粉

玉米面磨得越细，营养损失就越多，升糖指数也越高。因此吃粗玉米面好过精细的玉米粉，购买时尽量选择颗粒更大的玉米面，当然，相比之下，营养最全面的还是未加工过的甜玉米。

二、尽量少吃糯玉米面

糯玉米面一般会加工成黏性的食品，所以糖尿病患者朋友就要谨慎一些，少吃这些黏性的加工食品，避免血糖失控。

三、不要吃玉米面制品

一说到制品就跟原料不太靠边了，不管原料多么丰富，被再加工后营养会一层一层地逐渐损失，而且大量的添加物如糖和盐还会对身体造成损害，尤其是对于糖尿病患者。

怎么吃更好？

最好将全谷类和全谷类制品混合在白米、白面里制成杂粮饭、杂粮面，或直接将甜玉米当作主食，这样既能摄入优质均衡的营养，又有利于控制血糖。

虽然玉米和玉米面都是粗粮，但还是要注意控制摄入量，不论营养多么丰富的食物都要适量摄入才好。

最后祝大家生活愉快，身体健康！想了解更多心血管科普小知识，请关注我们，咱们下期见。

How do diabetics eat corn flour

Dear friends, nice to meet you!Now it is time for “Health talk for three minutes every day”,My name is Zhao Fanghui, a doctor of Daojian Doctor Group of Cardiovascular Rehabilitation.Today, I'm going to tell you how diabetic patients eat corn flour.

It is said that eating coarse grain is beneficial to diabetic patients.Can diabetic patients eat corn flour? In fact, this is related to the processing methods and varieties of corn flour. The sugar index of fresh sweet corn is about 55, which is lower than that of rice and steamed bread.However, the sugar index of coarse corn flour porridge is 66, and the fine corn flour is higher, which is almost the same as refined white flour and white rice. Because the corn porridge with deep crushing and long-time cooking contains less dietary fiber,it can be digested and absorbed more quickly, and its effect on blood glucose is also very fast. The starch contained in sticky corn is easier to digest and absorb than sweet corn, so waxy corn flour is more likely to raise blood sugar than sweet corn flour.

Therefore, diabetic patients need to pay attention to the following points.

Try to eat less fine corn flour

The finer the corn flour is ground, the more nutrition loss and higher sugar index. Therefore, it is better to eat coarse corn flour than fine corn flour. When buying, try to choose larger corn flour. Of course, the most comprehensive nutrition is unprocessed sweet corn.

Try to eat less glutinous corn flour

Glutinous corn flour will be processed into sticky food, so diabetic friends should be more cautious, eat less of these sticky processed food to avoid blood sugar out of control.

Don't eat corn flour products

No matter how rich the raw materials are, the nutrients will be gradually lost layer by layer after being processed. Moreover, a large number of additives such as sugar and salt will also cause damage to the body, especially for diabetic patients.

How to eat better?

It is better to mix whole grains and whole grain products in white rice and flour to make coarse grain rice and coarse grain flour, or take sweet corn as staple food directly,which can not only supply high-quality and balanced nutrition, but also help to control blood sugar. Although corn and corn flour are coarse grains, we should pay attention to control the intake. No matter how rich the nutrition is, we should take appropriate amount of food.

Finally, I wish you all a happy life and good health!To learn more about cardiovascular disease, please pay attention to us. See you next time.
