Blood sugar rises after eating rice because rice contains a relatively high amount of starch; when consumed in excess, this starch is converted into glucose and absorbed by the body, leading to elevated blood glucose levels. Eating rice together with coarse grains—foods rich in dietary fiber—can effectively help lower blood sugar.
