Nomikos T, Fragopoulou E, Antonopoulou S, Panagiotakos DB. (2018) Mediterranean diet and platelet-activating factor; a systematic review. Clinical  Biochemistry, 60:1-10.

 The systematic review by Nomikos et al. (2018) explores the impact of the Mediterranean diet on Platelet-Activating Factor (PAF), a lipid mediator implicated in inflammation, atherosclerosis, and other cardiovascular diseases. PAF promotes platelet aggregation, inflammation, and oxidative stress, all linked to cardiovascular risks. The Mediterranean diet, rich in bioactive compounds like polyphenols, omega-3 fatty acids, and monounsaturated fats, appears to reduce PAF activity, improving vascular health and lowering inflammation.

Key Findings

Inhibition of PAF Activity: The review highlights how Mediterranean diet components inhibit PAF synthesis and receptor binding, which reduces the molecule’s pro-inflammatory effects. Foods like olive oil, fish, whole grains, fruits, and vegetables—key elements of the Mediterranean diet—are shown to exert anti-inflammatory and anti-thrombotic effects through their interactions with PAF pathways.

Olive Oil and Polyphenols: Olive oil, rich in monounsaturated fats and polyphenols, is a major component that directly interferes with PAF metabolism. These compounds prevent PAF-induced platelet aggregation and reduce cardiovascular risks, enhancing the protective properties of the diet.

Omega-3 Fatty Acids: Found in high amounts in fatty fish, omega-3s have been observed to reduce PAF production. They shift the body towards anti-inflammatory states, which is beneficial for cardiovascular health and immune function.

Impact on Atherosclerosis: The Mediterranean diet’s role in reducing PAF activity contributes to lowering the risk of atherosclerosis by preventing the adhesion of platelets to blood vessel walls, thereby preventing plaque buildup and blockages.

Clinical Relevance: The authors conclude that adherence to the Mediterranean diet could be a significant dietary intervention for managing PAF-related health issues, especially in populations at risk for cardiovascular diseases and inflammatory disorders.

This review supports the cardiovascular and anti-inflammatory benefits of the Mediterranean diet, primarily through its regulation of PAF activity. By targeting PAF, the diet helps reduce platelet aggregation and inflammation, making it a key factor in promoting heart health. The findings suggest that broader public health initiatives could encourage Mediterranean diet adherence to mitigate cardiovascular disease risks.  The biological mechanisms behind the Mediterranean diet’s health benefits, shed light on how specific foods and nutrients t positively influence inflammation and platelet function.
