Let's analyze it for everyone. Glutinous rice is rice from which glutinous rice is shelled. It is also a kind of rice. Southerners like to call it glutinous rice, while northerners usually call it glutinous rice. People who don't know think this is called fragrant rice. Glutinous rice is used to make sticky snacks in most people's lives, such as zongzi or eight-treasure porridge. Neither southerners nor northerners will eat it as a staple food. The most fundamental reason is that people always think that glutinous rice is easy to fill and very difficult to digest, and eating too much is not good for human body.
For example, on the Dragon Boat Festival, our family doesn't advise us to eat more zongzi. Eat only one at a time. Eating too much means that you can't digest it, but this is actually a misunderstanding of glutinous rice. Compared with ordinary rice, glutinous rice is easier to digest and absorb. Both glutinous rice and rice contain starch, but glutinous rice contains less amylose and more amylopectin than rice. Usually amylopectin is easier to convert, so glutinous rice is digested faster. In fact, don't eat any other food after eating zongzi, and you will soon find yourself hungry again.
Glutinous rice tastes sticky. Usually, many people like to mix rice and glutinous rice when making rice porridge. Rice porridge will be sticky. If you just enlarge the rice, it is rice tea. The reason why glutinous rice is only added as an auxiliary material is because people have always misunderstood glutinous rice.
There is another reason why people don't take glutinous rice as the staple food, because most glutinous rice in the market is more expensive than rice, and people who live at home will definitely choose affordable food, so rice has become the first choice for people and has always been the staple food.
