Would you like to live healthier and longer?

We are all aging. In western culture this reality is often ignored or associated with the negative stereotype of declining mental and physical function however the reality is aging can be embraced and accompanied by excellent health. While there is no magic elixir for longevity it is possible to extend life and delay illness with a healthy lifestyle. An important element of a health promoting lifestyle is a healthy diet, and a diet that is emerging as a path to optimal health throughout our lifespan is the Mediterranean diet.  People who follow a traditional Mediterranean style dietary pattern not only live longer, but enjoy much healthier lives well into old age.

Where it began

Modern civilization emerged around the Mediterranean Sea, as we transitioned from nomadic life to farming we adopted dietary practices that have passed on through our culture. In the Mediterranean the use of foods such as olive oil, red wine, fish and an abundance of vegetables may have had a unique effect on longevity and health. The ancient Greeks preferred olives and olive oil as a source of fat over animal sources such as meat and dairy food. They deemed such foods unhealthy and eaten by barbarians (nomadic herders heavily reliant on animal foods).  In the 1950s it was found that the people of Crete were amongst the longest lived and healthiest in the world. A subsequent study by the World Health Organization found that of the worlds countries with the highest life expectancy, four of them are Mediterranean countries (1,2).

A recipe for longevity

A healthy diet and lifestyle can promote optimal ageing by protecting against damage to our DNA. This damage occurs as a result of oxidative stress caused by factors such as a poor quality diet, lack of exercise and emotional stress. Such damage over time may result in the development of disease and shorten our lifespan (3).

Several nutritional components of the traditional Mediterranean diet may reduce oxidative DNA damage over time, protect against disease and increase longevity. In particular a high intake of omega-3 fatty acids (4), olive oil (5), modest red wine (6), low red meat consumption (7) and abundant plant foods such as herbs, spices, whole grains, legumes, nuts, fruits and vegetables (8) have all been shown to prevent the development of disease. Importantly, this overall dietary pattern is associated with a higher intake of vitamins, minerals and disease fighting phytochemicals from plant foods (9,10).

Healthy aging is a reality

Several large studies across various countries world wide have recently found that people who eat close to the basic principles of a traditional Mediterranean diet have longer lives and are much less likely to suffer or die from diseases such as cancer and heart disease.  A traditional Mediterranean diet may also protect against obesity, osteoporosis, rheumatoid arthritis, cognitive decline, Alzheimer's disease, and Parkinson's disease (1). While we may still be chasing the eternal “fountain of youth” in medicine it seems it has been in the grocery store all along.
