A GUEST BLOGPOST

Last week I was enjoying a coffee at my old local coffee shop when I struck up a conversation with Eugenia, the owner of this blog. I am a life-course epidemiologist, meaning that I am interested in factors across the life course that impact health, well-being, and longevity.
These factors may not be obvious, and much of my work is exploring new potential risk factors for chronic disease. For example, I am currently funded by the National Heart Foundation of Australia to assess whether social connections with other people can prevent heart disease.
Eugenia and I soon realised our common interests in well-being and longevity. However, Eugenia taught me something very important that had escaped my attention. Eugenia was explaining the premise of her books “Greek Life” and “Greek Food For Sharing” which describe the benefits and lifestyle factors of the Mediterranean diet.
I instantly made the common mistake of thinking of the Mediterranean diet as simply the nutritional benefits provided to our bodies, but what Eugenia explained is that the Mediterranean diet is more than this, it is a way of life.
Eugenia explained that the secrets behind this way of living consist of both food and lifestyle factors. These include choosing the freshest and seasonal fruits and vegetables, consuming small quantities of nuts, dried fruits and natural yoghurt, generous amounts of olive oil, enjoying a glass or two of wine with meals and not as stand-alone events. The diet also encompasses multiple servings each week of legumes, two to three servings of seafood a week, and very limited dairy, red meat, and poultry. An abundance of herbs that are used in both cooking and for medicinal purposes, such as herbal teas.
Aside from the food, the Mediterranean Lifestyle encompasses having fun, being socially connected with family and friends, laughter, and incidental exercise by way of walking, gardening or dancing. Enjoying a cup of Greek coffee that’s prepared on the stovetop using pulverised coffee, means that this brew is packed with polyphenols and antioxidants, and these contribute to health and longevity.
Greeks are known to take a nap after lunch and this helps the body to rest, restore and reset. Another important lifestyle factor is the fasting rituals that include over 200 days a year where no dairy, meat or poultry is consumed, and this caloric deficit also contributes to health and wellbeing.
I’ve now learnt that these are the reasons why in some parts of Greece people enjoy longevity and good health well into their 90’s and to beyond 100. The island of Ikaria is one such place, and its been named as the island where people forget to die.
Instantly it all made sense. As researchers conducting data analysis we can only assess the variables that are available in the database. If someone is interested in nutritional content, dietary patterns, and food behaviours then they may ask a lot of specific questions about these factors. Some interests are not collected at all, and because of this we would have very little information of the ‘way of life’ that the Mediterranean diet encompasses. An example of this is reflected through much of the lifestyle choices, for example, the importance of social connections that attribute to wellbeing and longevity.
Why does it matter? The public health message that we receive is that the Mediterranean diet is the most beneficial for health. However, if someone decides to make a lifestyle change, then the Mediterranean diet definition only discusses the dietary pattern and nutritional content. Potentially the other elements as discussed above are not provided and therefore the person wanting to make the lifestyle change is not fully informed.
I can see that Eugenia’s books would be of benefit to people wanting to make a positive lifestyle change, not just for health but also for their well-being.
