The protective effect of the Mediterranean diet is significantly stronger for smoking-related cancers than for non-smoking-related cancers.

If you smoke, adopting a Mediterranean diet may offer you greater protection against cancer than if you were a non-smoker, particularly for cancers like lung, bladder, and colorectal. The diet's antioxidants may help counteract the oxidative damage caused by smoking.
