"Oil and health the prospects of the III millennium" was the title of the interesting conference that took place on Saturday 23 November in Vetralla, within the annual event "Si ... V'Olio", speaker on Prof. Francesco Violi, Director of the Department of Internal Medicine and Medical Specialties of the La Sapienza University of Rome.

Prof. Violi first mentioned the benefits of the 3 diets scientifically tested as effective in decreasing cardiovascular risks:

  1. Eskimo diet
  2. diet rich in fruit and vegetables
  3. Mediterranean diet

Mediterranean diet and extra virgin olive oil: benefits and effects

In particular, speaking of the benefits of the Mediterranean diet, Prof. Violi has shown a graph showing how the regular use of extra virgin olive oil in the diet is followed by a decrease in the mortality rate for cardiovascular events. The oil also has greater beneficial effects compared to the use of dried fruit (nuts, almonds, etc.).

Extra virgin olive oil and diabetes

At this point, the results of the research conducted by Prof. Violi and his team on 30 patients with impaired fasting glucose (IFG) were shown, who were randomly administered a meal containing or less 10 g of EVOO. (extra virgin olive oil). Before lunch, 60 minutes and 120 minutes after lunch, a blood sample was taken to measure: insulin, Glucagon-like peptide-1 (GLP1), dipeptidyl-peptidase-4 (DPP4) activity, triglycerides (TG), total cholesterol , HDL-cholesterol and Apo B-48. The results were surprising: the subjects who had taken the 10 g. of extra virgin olive oil showed a lower blood glucose increase of about 60 mg / dl at 120 and 20 minutes after the meal compared to those who had not taken EVOO. This is confirmed by the increase in insulin production in the subjects who had taken the 10 g. of oil in the meal.

Oleuropein (contained in extra virgin olive oil) lowers postprandial blood sugar

All that remained was to "discover" the person responsible for these beneficial effects, identified by prof Violi in oleuropein: the main polyphenol present in the leaves and fruits of the olive tree (oleuropein is found in olive oil both in the form linked to a glucose molecule (glycoside), which in the non-glycated form - Source Wikipedia).

Administered in the form of "medicine" (in tablets), oleuropein replicated the results of the study conducted by taking Evoo oil, verifying, says Prof. Violi, that "the consumption of 10 g of extra virgin olive oil with meals reduces postprandial blood sugar by about 20 mg / dl, potentially preventing the disease in those who are healthy, but also helping to manage it better in those who are already diabetic "

Chocolate for diabetics? Yes, if done using extra virgin olive oil

But that's not all, the conference ended with good news, especially for those with a sweet tooth and chocolate in particular. “Given the results we thought - Prof. Violi says - to analyze whether the addition of oleuropein, which we had identified as responsible for the decrease in postprandial blood sugar, in the preparation of the chocolate reduced the glycemic peak: the positive result obtained is very important, because this enriched product allows diabetics to be able to savor a normal chocolate, without sacrificing flavor. Above all, it allows patients to exploit the potential beneficial properties of chocolate: a few grams per day of cocoa has a good antioxidant and protection effect on the cardiovascular system, which must no longer be given up just because 'diabetic' chocolate is difficult to find or it is not as good as the normal one. "

The appointments of “Olio & Salute” continue, on Saturday 30 November Dr. Sara Farnetti will speak, title of the report “No more on a diet!”. The complete program on the website of the ProLoco of Vetralla.
