Extra-virgin olive oil contains oleocanthal, a compound that reduces inflammation in a way similar to ibuprofen, by blocking inflammatory enzymes. 

A 2005 study showed that these anti-inflammatory effects could help ease inflammation-related pain. It found that consuming around 50g (about 4 tablespoons) of extra-virgin olive oil daily would provide a small, regular dose of oleocanthal. 

Extra-virgin olive oil is expensive and if cost is a concern, you can alternate with other anti-inflammatory options such as rapeseed, flaxseed or avocado oils.
