When we think about how to protect our bodies from cancer, we often look for complex medical interventions. However, some of the strongest evidence might actually be found on our dinner plates. A massive review of 126 different studies involving over 8 million people looked at how a Mediterranean diet affects cancer risk.
The researchers found that people who stuck to this way of eating showed a lower risk for several specific types of cancer. This included head and neck, oral cavity, stomach, liver, bladder, and breast cancers. The data also suggested a lower risk of death from cancer overall.
While these results are encouraging, it is important to remember that these findings show an association rather than a direct cause. Because the data comes from many different studies rather than one single trial, we cannot say for certain how much the diet alone changes outcomes. It remains a strong piece of evidence for using nutrition as a tool in public health.
