Off topic: Insulin spike cut in half if take 1 tablespoon of extra virgin olive oil with meal – RCT June 2017

Extra virgin olive oil improves post-prandial glycemic and lipid profile in patients with impaired fasting glucose.

Clin Nutr. 2017 Jun;36(3):782-787. doi: 10.1016/j.clnu.2016.05.016. Epub 2016 May 28.


This was a small Randomized Controlled Trial with interesting results
Note: Vitamin D both prevents and treats diabetes
Hedge your bets: Add Vitamin D to your EV oiive oil
Perhaps add ~4,000 IU of Vitamin D /tablespoon of EVOO
Vitamin D form: premixed with olive oil (hundreds of suppliers on Amazon)
   or, lower cost, added as a powder from Bio-Tech capsules: (2 capsules of 50,000 IU per pint)

Overview Diabetes and vitamin D contains:

  • Diabetes is 5X more frequent far from the equator
  • Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
  • Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
  • Sedentary people get less sun / Vitamin D
  • Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
  • Elderly get 4X less vitamin D from the same amount of sun
        Elderly also spend less time outdoors and have more clothes on
  • All items in category Diabetes and Vitamin D 543 items: both Type 1 and Type 2

Vitamin D appears to both prevent and treat diabetes

Extra virgin olive oil (EVOO) improves post-prandial glycaemia in healthy subjects but it has never been investigated if this can be detected in pre-diabetic patients. We investigated if EVOO affects post-prandial glucose and lipid profile in patients with impaired fasting glucose (IFG).

Thirty IFG patients were randomly allocated to a meal containing or not 10 g of EVOO in a cross-over design. Before, 60 min and 120 min after lunch a blood sample was taken to measure glucose, insulin, Glucagon-like peptide-1 (GLP1), dipeptidyl-peptidase-4 (DPP4) activity, triglycerides (TG), total cholesterol, HDL-cholesterol and Apo B-48.

The meal containing EVOO was associated with a reduction of glucose (p = 0.009) and DPP4 activity (p < 0.001) and a significant increase of insulin (p < 0.001) and GLP-1 (p < 0.001) compared with the meal without EVOO.
Furthermore, the meal containing EVOO showed a significant decrease of triglycerides (p = 0.002) and Apo B-48 (p = 0.002) compared with the meal without EVOO. Total cholesterol and HDL cholesterol levels did not significantly change between the two groups.

This is the first study to show that in IFG patients EVOO improves post-prandial glucose and lipid profile with a mechanism probably related to incretin up-regulation.

From the web

  • “Though virgin olive oil (without the "extra") is produced through the same process and is not blended with other oils, it's made from slightly riper olives. It has a lighter flavor and is around 2% acidity. Use virgin olive oil for cold dishes or low-temperature cooking.”
  • “Extra virgin olive oil is mechanically pressed (you may see the term cold pressed) rather than being produced by chemical means. I has an acidity level of less than 0.8%. It is also tasted for flavour before being certified. Fine or Virgin Olive Oil has an acidity of less than 2%. It often uses slighter riper olives.”
  • “Virgin means the oil was made by simply pressing olives. It didn't undergo any of the industrial processes used to make 'refined' oils such as canola, sunflower, soybean and the lower grades of olive oil labeled 'Pure,' 'Light,' and simply 'Olive Oil.'”
