In a recent study from 2022, Hidayat Ur Rahman of the department of clinical pharmacy at Al-Jouf University, Saudi Arabia, found that compounds in olive oil could interact with C-reactive protein (CRP), the inflammatory biomarker that allows us to feel the sensation of pain. More precisely, CRP is found in blood plasma and concentrations will rise in response to inflammation. In healthy adults, the normal concentrations of CRP varies between 0.8 mg/L and 3.0 mg/L.
The experiment showed that all compounds could directly interact with CRP. Oleuropein had the most potent interaction with CRP, followed by indomethacin, oleocanthal, ibuprofen, phosphocholine, HT, and tyrosol.
With this study, Rahman suggested that olive oil, or at least certain elements of it, could be used in the design of future drugs and in the development of such as anti-inflammatory and anti-nociceptive phytomedicine at a low cost.
Decease prevention specialist Dr. William Li states that there are mainly three sorts of olives that packs extra anti-cancer compounds, these are: Picual (Spain), Moraiolo (Italy) and Koroneiki (Greece).
