The sugar here refers to the starch in the rice. How much sugar is equal to a bowl of rice is related to the capacity of the bowl and cannot be generalized. Generally, the starch in 100g of rice is about 25.6g, which is equal to about 25.6g of sugar. The sugar contained in rice, i.e. the starch in rice, is the main source of energy that rice provides for the body. The nutrient content of every 100g of rice is about 25.9g of carbohydrates, 2.6g of protein, 0.3g of fat, 0.3g of fiber, and a small amount of other various types of minerals and vitamins required by the human body components, which can provide the body with about 116 kcal of energy. Fiber cannot provide calories directly, so the carbohydrate minus the fiber content is the so-called sugar content of rice, which equals about 25.6g of sugar. The sugar content of rice is relatively high, so diabetics should eat white rice in moderation on a daily basis, and can partially replace it with coarse grains, mixed grains, mixed beans, and whole grains.
