The Mediterranean diet is closely linked with heart health, and researchers want to learn more about the underlying mechanisms behind this connection. In this study researchers analyzed the diet and health outcomes of 25,994 women for 12 years. Those most closely following a Mediterranean diet were 28% less likely to develop heart disease than those not following a Mediterranean diet. Even those who were only moderately following a Mediterranean diet had a 23% lower risk of heart disease, indicating that even small lifestyle changes can have a meaningful impact on health. The researchers suspect that part of the heart health beneﬁts may be related to lower inﬂammation, as women most closely following the Mediterranean diet had signiﬁcantly lower levels of biomarkers of inﬂammation. Other factors shown to aﬀect the relationship between the Mediterranean diet and heart health are the Mediterranean diet’s links to blood sugar management, BMI, blood pressure, and cholesterol.
