According to the WHO, cancer is one of the leading causes of death in the world. People in Mediterranean countries have a lower risk of certain types of cancer. Experts believe that the Mediterranean diet, which includes olive oil, may be the reason. A large meta-analysis from 2022 found that people who consumed the most olive oil had a 31% lower risk of developing cancer. This may be due to the antioxidants in olive oil, which can help reduce oxidative damage from free radicals, a major cause of cancer. See https://pubmed.ncbi.nlm.nih.gov/31480794/ for details.
Other research shows that the polyphenols in olive oil fight cancer cells as a kind of "target therapy". The cancer cells die within 30 minutes of ingesting polyphenol-rich olive oil. This research has not answered many questions, but it is clear that olive oil such as EH1200 has an anti-cancer effect. In particular, oleuropein, a polyphenol that produces a bitter effect on the tongue, is a promising candidate for cancer treatment. It may be used as an adjunct to existing cancer treatment guidelines or as a preventive therapy against relapse. See https://pmc.ncbi.nlm.nih.gov/articles/PMC9409738/ for more details.
