[14] Alcohol: 85,000 [11] 3.5%: Infectious diseases: 75,000 [11] 3.1%
Another 2014 review found that adherence to the Mediterranean diet was associated with a decreased risk of death from cancer. [27] A 2017 review found a decreased rate of cancer, although evidence was weak. [28] An updated review in 2021 found that the Mediterranean diet is associated with a 13% lower risk of cancer mortality in the general ...

Being overweight has been identified as a risk factor for cancer, and Walter Willett predicts that being overweight will overtake smoking as the primary cause of cancer in developed countries as cases of smoking-related cancer dwindle. [16] Being overweight also increases the risk of oligospermia and azoospermia in men. [17]
