C-reactive protein and interleukin-6 are measurable blood markers of inflammation in our bodies. Inflammation may be the cause of diseases like hypertension, strokes, hardening of the arteries (atherosclerosis), and heart attacks. One theory holds that if you can reduce the level of the inflammatory markers, your risk of the aforementioned illnesses will be lower.
Olive oil is a key component of the healthy Mediterranean diet. Could that healthfulness be mediated by anti-inflammatory effects of olive oil?
Fr0m the journal Nutrition:
[Randomized controlled trials] reveal beneficial effects of olive oil by reducing levels of inflammation markers. Olive oil taken on a regular basis can be a good dietary fat alternative, especially to manage IL-6 [interleukin-6]. However, further research is required to clarify the effects of olive oil consumption on inflammation comparing to other fats. Moreover, olive oil daily dosage, different time-length intervention and follow-up periods should be taken into consideration.
These researchers found no consistent effect of olive oil on C-reactive protein (CRP).
