Does rice that has been in a rice cooker for a day have a higher glycemic index GI than newly cooked rice?

Yes, rice that has been kept in a rice cooker for a day may have a higher glycemic index (GI) compared to newly cooked rice. This is due to the retrogradation process, where the starches in the rice undergo changes over time, potentially making them more digestible and leading to a quicker rise in blood sugar levels. However, the degree of change can vary based on the type of rice and cooking method.
