It relates to a method for manufacturing low-sugar rice using a low-sugar rice cooking device having a cooking plate having a rising or lowering function.

The daily sugar intake per capita in Korea was 40 g in 2002, and in 2012, 10 years later, the sugar intake increased by 38% to 65.3 g, and various diseases such as diabetes and cardiovascular disease are increasing.

In addition to the 184,000 deaths worldwide due to these diseases, there is a report that there will be a diabetes crisis in 2030 in Korea as the number of diabetes is rapidly increasing around the world. This is a result of reflecting the trend of increasing diabetes over the past several decades. In fact, the prevalence of diabetes over the age of 30 has increased from 1.5% in 1971 to about 12% in recent years, a whopping 7-fold increase over the past 40 years. A bigger problem is that the number of pre-diabetic patients with a very high risk of developing diabetes is estimated to be nearly double that of diabetic patients, so an explosive increase in diabetes is expected in the future.

Because of this sense of crisis, in 2011, the UN selected diabetes as one of the four non-communicable diseases that could threaten humanity in the future.
