Brief Summary

Extra virgin olive oil (EVOO) is known for its cardiovascular effects and its effect on glucose lowering. However, the effects of EVOO on the blood glucose of Type 2 Diabetes Mellitus Filipino patients has not been studied. The investigators aimed to determine whether a significant difference exists in meals containing EVOO versus meals without EVOO among Type 2 Diabetes Mellitus patients. Thirteen patients were included in this randomized controlled cross-over trial. They were randomized to receive a meal with or without EVOO followed by a one week wash out period, where they were given the other intervention. The primary outcome is the trans-meal blood glucose, which is calculated as the percent change in 2-hour postprandial blood glucose.

Outcome Measures

Primary Outcomes (1)

  • trans-meal blood glucose

    percent change in 2-hour postprandial blood glucose. This was calculated as the fasting blood sugar subtracted from the 2-hour postprandial glucose divided by the fasting blood sugar multiplied by 100

    2 hours

Study Arms (2)

Group A

EXPERIMENTAL

Initially received the test meal with EVOO, then on crossover, received the meal without EVOO

Dietary Supplement: Extra Virgin Olive Oil (EVOO)

Group B

NO INTERVENTION

Initially received the test meal without EVOO, then on crossover, received the meal without EVOO

Interventions

This study used the FDA approved Doña Elena Extra virgin olive oil, which is readily available in local supermarkets. Its free acidity expressed as oleic acid was found to be 0.26%, comparable with the International food standards.15

Group A
