简要总结

This study will implement a four-week dietary intervention among middle-aged and older adults with pre-diabetes. Participants assigned to the intervention arm will replace their usual cooking oil with diacylglycerol (DAG) oil, while those in the control arm will consume colza oil. All other lifestyle behaviors will be maintained without modification. The trial will determine the impact of DAG oil consumption on glycemic regulation, lipid metabolism, and body composition in this high-risk population.
