Staple foods such as noodles and rice are called carbohydrate foods. Eating carbohydrates will increase insulin, and the specific increase is called the rate of glucose increase. According to the rising speed of sugar, food is divided into fast carbon and slow carbon.

Reducing fat needs to maintain the stability of blood sugar, control the speed of sugar rise and minimize the conversion of carbohydrates into fat, so it needs slow carbon with low speed of sugar rise.

Brown rice is one of the slow carbon foods.
