Abstract

Type 2 diabetes (T2D) is a widespread health problem, especially in the elderly. Dietary strategies are essential for effective glycemic regulation and extra virgin olive oil is considered to improve insulin sensitivity and reduce inflammation, which could offer more advantages than other vegetable oils. This study examined the differential effects of EVOO and rapeseed oil supplementation on glycemic control and metabolic risk factors in 38 elderly Chinese women with T2D. The main detection indicators were FPG and HbA1c; and the secondary testing indicators were postprandial glucose, fasting insulin, HOMA-IR, lipid profile, and C-reactive protein. The results showed that EVOO had more significant advantages than rapeseed oil in improving blood glucose control and cardiovascular risk markers in elderly patients with type 2 diabetes.
