Highest adherence to the Mediterranean diet was associated with 20% lower CRP (p=0.015), 17% lower IL-6 (p=0.025), and 14% lower white blood cell counts (p=0.001) compared to the lowest adherence.

Does high adherence to the Mediterranean diet reduce inflammation and coagulation markers in healthy adults?
High adherence to the Mediterranean diet is associated with significantly lower levels of systemic inflammation and coagulation markers in healthy adults, providing a potential mechanism for its cardiovascular benefits.

OBJECTIVES: We studied the effect of the Mediterranean diet on plasma levels of C-reactive protein (CRP), white blood cell counts, interleukin (IL)-6, tumor necrosis factor (TNF)-alpha, amyloid A, fibrinogen, and homocysteine. BACKGROUND: To the best of our knowledge, the mechanism(s) by which the Mediterranean diet reduces cardiovascular risk are not well understood. METHODS: During the 2001 to 2002 period, we randomly enrolled 1,514 men (18 to 87 years old) and 1,528 women (18 to 89 years old) from the Attica area of Greece (of these, 5% of men and 3% of women were excluded because of a history of cardiovascular disease). Among several factors, adherence to the Mediterranean diet was assessed by a diet score that incorporated the inherent characteristics of this diet. Higher values of the score meant closer adherence to the Mediterranean diet. RESULTS: Participants who were in the highest tertile of the diet score had, on average, 20% lower CRP levels (p = 0.015), 17% lower IL-6 levels (p = 0.025), 15% lower homocysteine levels (p = 0.031), 14% lower white blood cell counts (p = 0.001), and 6% lower fibrinogen levels (p = 0.025), as compared with those in the lowest tertile. The findings remained significant even after various adjustments were made. Borderline associations were found regarding TNF-alpha (p = 0.076), amyloid A levels (p = 0.19), and diet score. CONCLUSIONS: Adherence to the traditional Mediterranean diet was associated with a reduction in the concentrations of inflammation and coagulation markers. This may partly explain the beneficial actions of this diet on the cardiovascular system.
Chrysohoou et al. (Thu,) conducted a cross-sectional in Healthy adults (n=3,042). Mediterranean diet (highest tertile of diet score) vs. Lowest tertile of diet score was evaluated on Plasma levels of C-reactive protein (CRP) (20% lower, p=0.015). Highest adherence to the Mediterranean diet was associated with 20% lower CRP (p=0.015), 17% lower IL-6 (p=0.025), and 14% lower white blood cell counts (p=0.001) compared to the lowest adherence.
