Japan, known as a longevity country, has been ranked first in the world longevity rankings for several years in a row. Some people say that their longevity is closely related to their diet, especially eating rice different from that of China people. Although Japanese also eat rice, the way they eat it is different from that of China, and most of them eat cold rice.

It is said that this kind of rice can also lose weight and help diabetics lower their blood sugar? Is cold rice really so magical?

What is the principle of cold rice?

As we all know, the taste of rice has been greatly improved after many times of fine processing, but its nutritional value is relatively low, and the most component is starch.

In essence, starch is divided into amylopectin and amylose, and after rice is heated, it is the starch in food that is gelatinized due to water absorption and expansion, which is used to supply daily energy after being eaten by people. This is the thermal processing of rice.

There is another process, that is, when people's leftover rice is preserved at low temperature, amylose and amylopectin are fully crystallized, because the aging of starch will produce zero-calorie resistant starch, just like why people don't want to eat cold rice directly. Because of the effect of resistant starch, rice will become extremely dry and hard, which will easily affect the taste.

In other words, this kind of rice has zero calories. If you can eat it, it will be helpful to control your weight. Unlike rice, people eat cold glutinous rice, which is still very soft and waxy. This is because glutinous rice is mostly amylopectin, and the degree of starch aging is very low, so it will not affect the taste when resistant starch is not formed.

However, as for eating cold rice to lower blood sugar, we should treat it correctly. Although rice will produce resistant starch after cooling and hardening, it can delay the increase of blood sugar after meals to some extent. Because the rice with unacceptable taste and high carbohydrate content will not affect the blood sugar index to a great extent as a whole, people who love sugar will affect the blood sugar level if they eat too much.

Therefore, it is not suitable for diabetics to eat rice alone. If you want to choose a staple food that is beneficial to blood sugar, you can do this: rice is mixed with coarse grains, which can be whole grains or whole grains. The combination of coarse grains and flour and rice helps to control the final blood sugar level.

If it is pasta, especially people who like pasta in the north, then we might as well do this, that is, mix fine and coarse flour together, such as white flour, buckwheat flour, rye flour, corn flour, oat flour, sweet potato flour and so on. Help diabetic patients to supplement nutrition and help to further stabilize postprandial blood sugar.
