more research on mediterranean diet

Eating a Mediterranean-style diet, rich in fruit, vegetables, olive oil and fish, may reduce the risk of dying from cancer and cardiovascular disease, says a new US study.

A study of almost 400,000 people with an age range of 50 to 71 reports that greater adherence to a Med-style diet reduced the risk of death from cardiovascular disease (CVD) and cancer by 22 and 17 per cent in men, and 12 per cent for women.

"To our knowledge, the present study is the first and largest US cohort to evaluate the Mediterranean dietary pattern and mortality," wrote lead author Panagiota Mitrou in the Archives of Internal Medicine.

Translated to English: this is the first study of the Mediterranean diet in a US population.

The key features of the traditional mediterranean diet are fish, nuts, vegetables, and olive oil.

You've always got to remember with these kinds of studies that they are correlation studies- that means they simply show two things are related (in this case the Mediterranean diet and lower mortality). They don't prove one causes the other. But it's hard to ignore the "circumstantial" evidence that the Mediterranean diet has been linked with lower rates of cancer and heart disease and dying in dozens of research studies. Let's not forget, though, other features of the Mediterranean lifestyle that could have a major impact on health- being out in the sun, physical labor, laughing a lot, eating big meals earlier in the day, and napping.

The study adds to an ever-growing list of research supporting the health benefits of consuming a traditional Mediterranean diet (TMD), with evidence linking the diet to lower incidence of heart disease, obesity and certain types of cancers.
