Adherence to a Mediterranean diet supplemented with extra-virgin olive oil significantly reduces the incidence of breast cancer in women.
Incorporate extra-virgin olive oil into your daily diet as a primary fat source. This is particularly beneficial for women, as it is associated with a significantly lower risk of breast cancer when consumed as part of a Mediterranean diet.
Among 4152 women included in the analysis, women allocated to the MedDiet supplemented with extra-virgin olive oil group exhibited a 68% relatively lower risk of incident breast cancer (HR = 0.32, 95% CI 0.13–0.79) compared to the control group.
Why this rating
Based on a secondary outcome of a large RCT (PREDIMED) with a small number of observed cases (n=35), limiting statistical power despite significance.
