The Cretan Mediterranean Diet: A Dietitian’s Perspective from Growing Up in Crete

I grew up on the island of Crete, where olive oil, honey, and home-grown produce were part of everyday life. Meals were simple, seasonal, and shared - less about following a “diet” and more about how people lived.

Looking back, this way of eating closely reflects what research now describes as traditional Mediterranean dietary patterns: local, minimally processed, plant-rich foods, rich in extra-virgin olive oil, and embedded within a social, active lifestyle (Godos et al., 2024).

What Makes the Cretan Mediterranean Diet Special?

Scientific descriptions of the “reference” Mediterranean diet are based on dietary patterns observed in Crete, other parts of Greece, and Southern Italy in the mid-20th century.

These patterns were characterised by high intakes of vegetables, fruits, whole grains, legumes, nuts, and olives; olive oil as the main source of fat; modest amounts of fish and poultry; minimal red meat; moderate wine consumption with meals; and simple, home-style cooking (Guasch-Ferré & Willett, 2021; Giuffrè & Giuffré, 2023).

Many of the features highlighted in research were simply part of everyday life growing up in Crete:

• Foods were local, seasonal, and minimally processed (home-pressed olive oil, home-made cheeses, home-grown vegetables)

• Legumes, wild greens, nuts, seeds, herbs, and spices were used regularly, not occasionally

• Wine, when consumed, was typically with meals and in moderation

• Meals were slow, social, and part of a broader lifestyle that included physical activity, rest, and strong community ties.

Key Health Benefits Backed by Research

What I experienced growing up in Crete has since been widely studied in nutrition research. Mediterranean dietary patterns, originally characterised in populations including Crete, are now examined across diverse populations. Higher adherence is consistently associated with better cardiometabolic health and a lower risk of several chronic diseases.

Cardiovascular health and longevity

Evidence from large cohort studies and meta-analyses indicates that greater adherence to the Mediterranean diet is associated with a lower risk of cardiovascular disease, stroke, and cardiovascular mortality, as well as reduced all-cause mortality (Hu, 2023).

Randomised clinical trials also provide evidence of benefit in high-risk populations. In the Lyon Diet Heart Study, which used a Mediterranean diet adapted from traditional Cretan dietary patterns, participants with previous myocardial infarction experienced substantially lower rates of recurrent cardiac events and mortality compared with those following a standard prudent low-fat diet (Renaud et al., 1995; Kok & Kromhout, 2004).

Across prospective cohort studies involving large populations, higher Mediterranean diet adherence scores are associated with progressively lower risk of coronary heart disease and overall mortality (Guasch-Ferré & Willett, 2021).

Metabolic health and diabetes risk

Mediterranean dietary patterns have also been linked with improvements in several cardiometabolic risk factors. Reviews and meta-analyses report associations with lower body weight and waist circumference, improved blood pressure, improved lipid profiles, better glycaemic control, and greater insulin sensitivity (Hu, 2023; Guasch-Ferré & Willett, 2021).

Higher adherence to the Mediterranean diet is associated with a lower risk of type 2 diabetes and metabolic syndrome in observational studies and intervention trials (Hu, 2023).

In addition, evidence from substitution analyses suggests that replacing animal-based foods such as processed meats and butter with plant-based foods - including nuts, legumes, whole grains, and plant oils—is associated with lower risk of cardiovascular disease, type 2 diabetes, and all-cause mortality (Neuenschwander et al., 2023).

Cancer, cognitive health, and healthy ageing

Higher adherence to Mediterranean dietary patterns has also been associated with a lower incidence of several chronic diseases and some cancers, including colorectal cancer, although the strength of evidence varies by cancer type (Kiani et al., 2022; Guasch-Ferré & Willett, 2021; Dominguez et al., 2021; Kaufman-Shriqui et al., 2022; Romagnolo & Selmin, 2017; Tosti et al., 2018; Rees et al., 2019).

Observational studies further suggest that Mediterranean dietary patterns are associated with slower cognitive decline and a lower risk of Alzheimer’s disease and mild cognitive impairment, although findings for all-cause dementia remain less consistent across studies (Hu, 2023; Guasch-Ferré & Willett, 2021; Dominguez et al., 2021; García-Hernández et al., 2023; Kaufman-Shriqui et al., 2022).

Taken together, this body of evidence suggests that long-term adherence to Mediterranean-style dietary patterns may support healthy ageing and a reduced burden of age-related chronic disease (Hu, 2023; Giuffrè & Giuffré, 2023; Dominguez et al., 2021; Romagnolo & Selmin, 2017; Tosti et al., 2018; Godos et al., 2025).

Why it Works: The Whole Dietary Pattern

What stands out in the research is that the benefits of the Mediterranean diet are unlikely to be explained by any single food or nutrient. Instead, they appear to arise from the combined effects of the overall dietary pattern and the way it is lived.

Evidence from experimental and observational studies suggests several biological pathways through which Mediterranean dietary patterns may influence health.

Key mechanism	Evidence from research
Lipid metabolism	Associated with reductions in LDL cholesterol and improvements in overall lipid profiles (Kiani et al., 2022; Guasch-Ferré & Willett, 2021; Giuffrè & Giuffré, 2023; Dominguez et al., 2021; Scaglione et al., 2025)
Anti-inflammatory and antioxidant effects	Plant foods, herbs, and extra-virgin olive oil provide polyphenols and other bioactive compounds that may reduce oxidative stress and inflammatory pathways (Kiani et al., 2022; Gorzynik-Debicka et al., 2018; García-Hernández et al., 2023; Romani et al., 2019; Kaufman-Shriqui et al., 2022; Tosti et al., 2018)
Vascular function	Mediterranean dietary patterns have been associated with improved endothelial function and reduced atherosclerotic progression (Kiani et al., 2022; Giuffrè & Giuffré, 2023; Dominguez et al., 2021; Kok & Kromhout, 2004; Rees et al., 2019)
Metabolic regulation	Associated with improved insulin sensitivity and glycaemic control (Kiani et al., 2022; Hu, 2023; Giuffrè & Giuffré, 2023; Dominguez et al., 2021; Scaglione et al., 2025)
Gut microbiota and cellular pathways	Emerging research suggests Mediterranean diets may influence gut microbiota composition and molecular pathways linked to metabolic and ageing processes (Kiani et al., 2022; Dominguez et al., 2021; Kaufman-Shriqui et al., 2022; Tosti et al., 2018)

Bringing Cretan Traditions into Daily Life

Research also highlights that the Mediterranean diet represents more than a list of foods - it reflects a broader way of living. Traditional Mediterranean cultures emphasise regular physical activity, shared meals, adequate rest, and strong social connections, all of which may contribute to the health benefits observed in population studies (Godos et al., 2024; Giuffrè & Giuffré, 2023; García-Hernández et al., 2023; Sikalidis et al., 2021; Scaglione et al., 2025; Rees et al., 2019; Godos et al., 2025).

Looking back, this is what stood out most from my experience growing up in Crete—food was never separate from daily life. Meals were shared, unhurried, and part of a wider rhythm that included movement, rest, and time spent with others.

Even outside Mediterranean regions, elements of this pattern can be adapted by:

• prioritising vegetables, legumes, whole grains, and olive oil as the foundation of meals

• treating meat as a smaller component rather than the centre of the plate

• preparing simple meals at home using seasonal ingredients and herbs

• taking time to eat socially, rather than eating quickly or alone

  
  

Summary

The traditional Cretan Mediterranean diet described in historical research closely reflects patterns that have been widely studied in nutrition science. Evidence from cohort studies, systematic reviews, and clinical trials indicates that higher adherence to this dietary and lifestyle pattern is associated with improved cardiometabolic health, a lower risk of several chronic diseases, and more favourable markers of healthy ageing (Kiani et al., 2022; Hu, 2023; Guasch-Ferré & Willett, 2021; Giuffrè & Giuffré, 2023; Dominguez et al., 2021; Kaufman-Shriqui et al., 2022; Romagnolo & Selmin, 2017; Tosti et al., 2018; Rees et al., 2019).

For me, this way of eating was never about following a specific diet—it was simply a way of living. The challenge now is not to replicate it perfectly, but to understand what aspects can realistically be carried into modern life.
