Insulin is the enzyme of the body that helps in the use of sugar from the blood, thereby stabilizing blood sugar level. When insulin production is deficient, it affects the blood sugar level, thus leading to diabetes.

Research has shown that olive oil increases insulin production by increasing the levels of another enzyme in the gastrointestinal tract, incretins, which stimulates insulin production.

2. Reduce post-prandial blood sugar level

Extra virgin olive oil can reduce postprandial blood sugar levels by about 20mg/dl. This effect is brought about by oleuropein found in the oil.

3. Reduce body’s glycemic response

When extra virgin olive oil is eaten with a high glycemic meal by a person with diabetes, the oil reduces the body’s glycemic response to such meal, thereby acting as a buffer, preventing high blood sugar spikes.

What Are The Other Oils Diabetics May Use? The Better And The Worse

Other than olive oil, there are a few other oils suitable for use by people with diabetes. When there’s the unavailability of the oil, these alternatives will suffice.

Palm Oil vs Canola Oil

The palm oil referred to here is refined palm oil, RPO. Palm oil, just like olive oil is healthy, and rich in vitamins
and antioxidants.

Canola oil, is rich in unsaturated fatty acids, good for cholesterol levels, but both oils, contain vitamins and antioxidants that make it healthy for use by diabetics, compared to vegetable oils.

But canola oil is considered better for heart and cardiovascular diseases instead of diabetes. This is because of its fat content, as compared to that in palm oil.

People with diabetes will benefit heavily from extra virgin olive oil consumption, as it is effective in the maintenance of blood sugar levels.
