Adherence to a Mediterranean dietary pattern is associated with a significantly reduced risk of breast cancer, with a particularly strong protective effect against triple-negative tumors.
Adopting a Mediterranean dietary pattern—characterized by high consumption of vegetables, legumes, fruits, oily fish, and olive oil, and low consumption of processed meats and refined grains—is associated with a significantly lower risk of breast cancer. This protective effect is particularly pronounced for triple-negative tumors, suggesting that dietary choices may play a crucial role in preventing aggressive forms of the disease.
In contrast, the Mediterranean pattern was related to a lower risk (OR for the top quartile vs the bottom quartile 0.56 (95% CI 0.40–0.79)). ... the protective effect of our Mediterranean pattern was stronger for triple-negative tumours (OR ¼ 0.32; 95% CI 0.15–0.66)
Why this rating
Large case-control study (n=1946) with rigorous matching and adjustment for confounders, though observational design limits causal inference.
