Compared to rice and porridge of the same weight, rice has a higher sugar content and has a higher glycemic index. Taking rice as an example, rice porridge has a higher glycemic index than rice congee of the same quality due to the higher water content in the congee. The Chinese Food Composition Table 2002 shows that the glycemic index of rice is 83.2, while that of rice porridge is 69.4, indicating that rice provides more sugar and calories than porridge, which has a relatively greater impact on postprandial blood glucose. For people who need to control blood glucose and reduce weight, they can moderately increase the intake of staple foods such as corn porridge, noodles, and mixed grains rice in their diets, which provide nutrients such as carbohydrates with relatively low calories. It is recommended that people with high blood sugar consult an endocrinologist or dietitian for specific dietary regimens.
