Cancer and cardiovascular diseases (CVD) are the leading causes of mortality and morbidity worldwide. Dietary patterns play a crucial role in the prevention and management of these life-threatening diseases. Moreover, the Mediterranean diet (Med-Diet) is consistently associated with health benefits. Therefore, the current study attempted to synthesize the contemporary scientific evidence, outlining the impact of Med-Diet on CVD. The key components of this dietary pattern include a high intake of fruits, vegetables, whole grains, seafood, olive oil, and moderate consumption of poultry and dairy products which interact to provide protective effects against these diseases. The Med-Diet  emphasizes the use of monounsaturated fats from olive oil and polyunsaturated fats from seafood, which significantly contribute to cardiovascular health. This diet is also rich in antioxidants and phytochemicals, offering potential protective qualities against cancer through combating inflammation and oxidative stress. High fiber content contributes to a healthy digestive system and potentially reduces the incidence of colorectal cancers. While, the Med-Diet alone cannot guarantee complete immunity against these diseases, it is an essential element of a holistic approach to disease prevention and management. Moreover, it also reinforces the importance of incorporating dietary patterns into public health strategies. To strengthen the evidence base, future research should focus on long-term randomized controlled trials in diverse populations.
