Type 2 Diabetes and Olive Oil: Blood Sugar Balance

5 min read 2026-01-15ELMAR CRETE

Diabetes and Nutrition

Type 2 diabetes is a rapidly growing health problem worldwide. Nutrition plays a central role in preventing and managing the disease, and extra virgin olive oil shows promising results here.

Insulin Sensitivity

The monounsaturated fats in olive oil can help cells respond better to insulin, which means more stable blood sugar.

A sub-analysis of the PREDIMED study in Spain showed that a Mediterranean diet rich in extra virgin olive oil significantly reduced the risk of developing type 2 diabetes.

Post-Meal Blood Sugar

Olive oil added to a meal slows carbohydrate absorption, softening the sharp post-meal blood-sugar spikes (glycaemic response). For example, the glycaemic effect drops when olive oil accompanies white bread.

Polyphenols and Inflammation

Diabetes is linked to chronic low-grade inflammation. The anti-inflammatory effect of olive oil polyphenols may be supportive against this.

Practical Tips

  • Use cold-pressed extra virgin instead of refined vegetable oils
  • Cook vegetables and legumes with olive oil
  • Reduce sugary and processed foods
  • Consult your doctor before making changes
