Southern Europeans are among the healthiest and longest living humans on the planet, according to studies on quality of life and longevity in different parts of the world. Considering the economic crisis that has taken hold of the region over the past few years, this seems almost a paradox. Experts have long suspected that good eating habits as well as a slower-paced lifestyle are largely responsible for these advantages.
A recently completed study from Spain has now confirmed some of these assumptions. It found that people who followed what is called the “Mediterranean diet” could lower their risk of heart disease by up to 30 percent.
As the name indicates, the Mediterranean diet is based on the culinary cultures of countries bordering on the Mediterranean Sea. It consists mainly of fresh fruit and vegetables, fish, lean meats, whole grains, olive oil, nuts and also wine with most meals.
Even by comparison to Northern Europeans who have a similar or even higher standard of living, Southerners show overall lower rates of heart disease. One of the reasons for this may be that olive oil and nuts contain monounsaturated fats, which are more conducive to maintaining artery health than saturated fats in butter and lard, more commonly used in the north.
For the study, over 7,400 participants between the ages of 55 and 80 were assigned slightly different diet regimens. All were at an increased risk of developing heart disease at the outset of the study because of other illnesses such as diabetes, high cholesterol and high blood pressure as well as weight problems, family history and poor lifestyle choices. Surprisingly, those who were given olive oil and a selection of nuts in addition to their regular food intake did best in improving their health condition.
The benefits of the Mediterranean diet seem also applicable to age-related mental health. In a separate study, researchers from the Columbia University Medical Center in New York found that participants who followed the dietary guidelines most strictly could cut their risk of developing Alzheimer’s disease by up to 40 percent. The reasons are similar to those for heart disease. Experts believe that uninhibited blood flow to the brain, enabled by good heart functions and unobstructed arteries, is crucial for the prevention of mental decline.
Of course, it would be naive to assume that dietary improvements alone would make us altogether healthier and let us live longer. For instance, to prevent heart disease, it is not only important to eat right but also to exercise regularly, manage stress, get enough sleep and also have loving relationships in one’s life. We affect our health not only by the way we eat but also how we behave, said Dr. Dean Ornish, founder of the Preventive Medicine Research Institute in Sausalito, California. It’s not just one thing that will make us well but a “spectrum program” of choices, as he calls his comprehensive approach to disease prevention and better health.
One of the most important aspects of the Mediterranean lifestyle is having close ties with family and friends. Sharing meals, taking time for conversation, celebrating special occasions surrounded by loved ones – all of that contributes to people’s well-being.
“Study after study has shown that people who are lonely and depressed and isolated – and I think that’s a real epidemic in our culture – are three times more likely to get sick and die prematurely than those who have a sense of love and connection and community,” he said in an interview. “In part this is because when you are feeling lonely and depressed, you’re more likely to smoke, overeat, drink, work too hard, abuse yourself in different ways, as a way of just getting through the day.” In the end, he added, what matters most is your overall way of living.

Where you live may determine how healthy you are or can hope to be, according to a new study published in the American Journal of Preventive Medicine. Researchers using a geographic information system (GIS) found that access to quality food outlets and opportunities to be physically active can make communities not only more attractive but also more healthy.
Both children and adults who live in areas that provide supermarkets within reasonable distance, recreational parks and safe sidewalks and bike paths have on average lower rates of obesity, diabetes and heart disease than those living in underserved neighborhoods, including so-called food deserts.
“The biggest difference we found in rates of obesity were in places where the environment was good for both nutrition and physical activity,” said Dr. Brian Saelens, professor of pediatrics at Seattle Children’s Research Institute and co-author of the study report. “The rates [in the best places] were less than 8 percent. But if the nutrition and physical activity were not good, the rates went up to 16 percent.”
Although these findings should not come as a surprise, it is the first time that scientists have used geographic data to specifically investigate the causes of lifestyle-related health problems.
Up to now, most studies on the ever-rising obesity epidemic have been focusing on factors such as lifestyle, income, education and genetic preconditions. Geographic differences should be used more often in the future to assess the connections between nutrition, physical activity and obesity. For instance, if we can count the numbers of grocery stores, convenient stores, fast food restaurants and recreational facilities in a particular area, we may be able to predict better what chances the local population has to live more healthily, the researchers said.
“To address this health crisis, attention must be focused on a key issue that lies at the core of the epidemic: The social inequities of obesity,” said Rear Admiral Susan Blumenthal, MD, MPA, a former U.S. Assistant Surgeon General.
“A significant body of scientific evidence links poverty with higher rates of obesity. Families with limited economic resources turn to food with poor nutritional quality because it is cheaper and more accessible. Low-income families live in neighborhoods where it is dangerous to play outside, reducing opportunities for both children and adults to exercise. Instead of supermarkets, [low-income] neighborhoods may have an abundance of fast-food retailers and corner stores that are stocked with products high in fat and low in nutrients. Families are often targeted by food marketers with advertisements encouraging the consumption of nutrient-poor foods, increasing the likelihood of adopting unhealthy dietary practices.”
Despite of their best efforts to lure more supermarkets to underserved neighborhoods through tax breaks and other incentives, local governments find it hard to overcome the many obstacles they’re facing. The so-called food deserts in many poor urban and rural areas persist because of lack of consumer demand (people don’t have the money to buy nutritious but pricey foods), high crime rates (and insurance costs) and transportation expenses (to remote areas).
An area is officially considered a food desert when it has no supermarkets within 1 mile in an urban setting and within 10 miles in a rural environment. The U.S. Department of Agriculture (USDA) estimates that nearly 25 million Americans live in food deserts.
Social welfare programs such as food stamps bring only limited relief because of geographic hindrances. According to data collected by the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Health and Human Services (HHS), a quarter of all food stamps recipients do not have easy access to supermarkets. High gas prices and lack of private or public transportation only worsen the situation.
Obviously, not all or even many of these conditions can be changed overnight. However, a few small steps in the right direction can go a long way. Communities have taken initiatives all over the country to facilitate more local farmers markets and sales outlets for urban farms where fresh foods are available at affordable prices. Achieving better “walkability” has become a goal in cities and towns of all sizes. With greater awareness, good will and some imagination, we all can make a difference for ourselves and our neighborhood.
