Mediterranean Mechanism

Consistently elevated post-meal lipemia [blood triglyceride levels] (PPL) is a major risk factor in cardiovascular disease.  A number of previous studies suggest that elevated levels of triglycerides (fats) in the blood after meals, known as postprandial lipemia (PPL), associate with an increased risk for hardening of the arteries.  Maria Maraki, from Harokopio University (Greece), and colleagues explored the effects of a “Mediterranean lifestyle” — marked by high intake of monounsaturated fats (MUFAs), fiber, legumes, dairy and fish; moderate alcohol intake; and increased amounts of better quality sleep on cardiovascular risk factors.  Observing that: “Numerous studies have shown that Mediterranean diet may reduce [post-meal blood triglyceride levels],” the study authors write that: “more studies are needed to confirm short-term results and investigate the effects of the whole Mediterranean lifestyle on [post-meal blood triglyceride levels] and whether these effects mediate its protective role on [cardiovascular disease].”
