Researchers collaborated to compare Greeks who closely followed the Mediterranean diet to those who followed it more loosely.
Greeks who lived abroad showed higher adherence to the Mediterranean diet by eating “significantly more” cereals, legumes, vegetables and fruits.
Greeks who lived in Greece “consumed significantly more” dairy and potatoes.
The consumption of meat, poultry, fish and olive oil was similar between both groups.
By looking at both groups, the authors concluded that strict adherence to the Mediterranean diet is associated with “higher levels of successful ageing among people of the same genetic background, living in different environments”.
The authors noted: “Traditional dietary habits are gradually abandoned in their native countries.
“[But] are considered cultural heritage and preserved accordingly among immigrants.”
The executive dean of RMIT University Bundoora’s School of Health and biomedical science in Australia, Catherine Itsiopoulos, commented on the research she worked on.
“The Greek population is amongst the longest-living populations in the world, and rates of ageing remain high compared to other European countries,” she said.
However, Itsiopoulos told Olive Oil Times that “the prevalence of chronic diseases in Greece, such as heart disease, stroke, dementia and depression, are on the rise”.
In addition to diet, Itsiopoulos recognised there are many factors that affect longevity.
These included smoking status, physical activity levels, educational achievements and financial standing.
Itsiopoulos said: “Our study has shown that people’s personal lifestyle choices, social supports, cultural practices and where they live play a very important role in successful ageing.”
The Mediterranean diet
Heart UK lists nine “Mediterranean essentials”, which is connected to successful ageing. These are:
- At least five portions of fruit, vegetables and pulses every day
- Nuts and seeds daily
- Two meat-free days each week
- Three portions of wholegrains daily
- Two portions of fish or seafood weekly
- Pulses in meals at least twice weekly
- Using olive, rapeseed and sunflower oils
- Use onions, leeks, tomatoes and garlic
- Cooking most meals from fresh and unprocessed ingredients.
The Mediterranean diet is a good source of omega-3 fatty acids, potassium, fibre, and antioxidants.
By following the Mediterranean diet you are helping to protect your body from disease.
