Does the Mediterranean Diet actually reduce Cardiovascular Risk?



Research fails to account for one of Modern Societies greatest failures.

If you are concerned about diet and health you probably heard of the recent study published in the New England Journal of Medicine touting the positive effects of the Mediterranean Diet on Cardiovascular disease.  For your reference, The Mediterranean Diet refers to the traditional dietary patterns of southern Italy, Greece and Spain.  The principal aspects of this diet include relatively high consumption of olive oil, legumes, unrefined cereals, fruits and vegetables, and moderate to high consumption of fish, moderate consumption of dairy products (mostly as cheese and yogurt), moderate wine consumption, and low consumption of meat and meat products.   Now, to some this bit of news may be a revelation while to others simply another pseudo solution presented in the media that surely will be opposed by the next great study.

Obviously the content of our diet is very important to our survival but did our ancestors spread throughout the world concern themselves with dietary questions?  Wasn't diet more a question of what was available and edible versus heart healthy?   And given today’s culture that replaces physical activity with emotional stress, can we afford to focus so intently on diet without paying as much attention to our physical and emotional well-being?


Interestingly, these questions were answered some 50 years ago but like many discoveries that go counter to beliefs, they were buried only to become part of the lore of a small clan of Italian-Americans in Pennsylvania.


Nicola Rosato
In 1882 a group of men from Roseto Valfortore (Valley of Roses), a town of 1300 located near the Province of Foggia in the Southern Italy, set sail for New York. Because they had experience working in the marble quarries back in Italy, they migrated 75 miles west of New York City to work in the Slate quarries of Bangor Pennsylvania.  The experience was not as positive as they had expected.  The conditions were harsh and they were treated just as poorly as they were in Roseto Valfortore.  But, they persisted and in 1912 established their own community. The Borough of Roseto was the first 100% Italian community in the USA. 






In the early 60’s a local physician conveyed to Dr Stewart Wolf, Head of Medicine at Oklahoma University and a summer resident of the region, that the people of Roseto were practically immune to heart disease.  He had treated much of the population of Roseto and surrounding villages for the past 17 years and had not seen in the Rosetans a case of heart disease in anyone under the age of 65 years.  To confound this finding, the Rosetans were heavy smokers and drinkers, ate fatty meats cooked in lard and generally battled obesity.




Intrigued, Wolf along with sociologist John Bruhn opened the Tott Gap Medical Research Facility for the purpose of conducting a study of people of Roseto.  The results were astonishing. Virtually no one under 55 died of a heart attack; for men over 65, the death rate from heart attack was half that of the United States as a whole; and the death rate from all causes was 35% lower than the National average. There was no suicide, no alcoholism, no drug addiction, and little crime to speak of.  These people died of old age. That’s it!



Dr Stewart Wolf
By the time the study was published, Dr Wolf had determined that it wasn’t diet that gave this population such resilience to disease.  Their native diet was altered over the years due to availability.  Genetics had also been ruled out as was the region of Pennsylvania where they resided.  The secret to their health and longevity was their Community.  People of Roseto communicated with each other on a daily basis, were perpetually visitors in each other’s homes and were genuinely interested in their neighbor’s well-being.  Multiple generations lived under one roof and the Grandparents were revered by all.  They socialized with each other, worshiped together and were united in the ideal of creating a better life for their children.  In essence, they created the culture that they all desired without respect for what the rest of the world was doing. 


Sadly, by the late sixties the world caught up with the next generation of Rosetans.  Some of the families became more prosperous causing tension in the community.  Others became more educated and if they weren’t pulled away from Roseto they abandoned the cultural habits that had benefited their ancestors.   For the next generation, heart disease rose above the national standards as they became enmeshed in the American dream.

A recent article in the Wall Street Journal noted that 37% of educated Americans move away from their town of origin for work.  This is the highest rate of migration in the world.   Couple that with the increase pace of life, the diminished art of face to face communication and the ever decreasing leisure time, is it any wonder for the waning of the sense of belonging to a Community?


The Orlandi's-Giovanni, Florinda Maria his wife, and Agata his daughter-arrived in America 100 years ago (June 13,1913). Four generation of Orlandi's later the family is still going strong and growing 


Personally, I can relate to both sides of this dilemma.  My maternal grandparents immigrated to Roseto Pennsylvania 100 years ago this June.  I was raised in the same culture that Dr Wolf documented.  I miss people knowing me through my family tree; I was always known as the Shoemaker’s son or one of the Orlandi’s.     The last 23 years I have lived in Cincinnati, long enough to establish roots but never developing the type of connectedness that comes about from living in ones hometown.  I’m not recommending we try to recreate a Community like Roseto.  But, I do hope all who read this take note that as humans we thrive when we establish a balance between our physical, chemical and emotional beings; no one part is more important than the other.
