The Southern European Atlantic diet is associated with lower coronary risk
The Southern European Atlantic Diet (SEAD) is the traditional diet of Northern Portugal and Galicia, a region in northwest Spain. The SEAD has been associated with a lower risk of non-fatal acute myocardial infarction, but the mechanisms of this association have not yet been investigated. A study examined the association between the SEAD and numerous biomarkers of coronary risk, blood pressure and anthropometrics. A cross-sectional study was conducted in 2008-2010 among 10,231 individuals representative of the population aged 18 years and older in Spain. Diet was assessed with a validated computerized diet history. SEAD adherence was measured with an index including 9 food components (fresh fish, cod, red meat and pork products, dairy products, legumes and vegetables, vegetable soup, potatoes, whole-grain bread, and wine), which ranges from 0 (lowest adherence) to 9 (highest adherence). C-reactive protein, uric acid, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, glucose, glycated hemoglobin, insulin, leptin, fibrinogen, were determined in 12-h fasting blood samples, while creatinine and urine albumin were determined in urine. Mean SEAD score was 2.9 points. Higher SEAD adherence was associated with a lower level of plasma C-reactive protein, plasma triglycerides, insulin, HOMA-IR, urine albumin, urine albumin-creatinine ratio and systolic blood pressure. This study identifies possible mediators of the effect of SEAD on myocardial infarction, because SEAD is associated with a lower concentration of markers of inflammation and with reduced triglycerides, insulin, insulin resistance, and systolic blood pressure.
