How does the Mediterranean diet impact longevity?

Introduction

The Mediterranean diet (MD) is widely recognized for its potential health benefits, particularly in relation to longevity and the prevention of age-related diseases. This diet emphasizes the consumption of fruits, vegetables, whole grains, nuts, olive oil, and moderate wine intake, while limiting red meat and processed foods. Numerous studies have investigated the impact of the MD on lifespan and overall health, providing valuable insights into its effectiveness.

Key Insights

Longevity and Mortality Reduction
- Adherence to the MD is associated with a significant decrease in overall mortality, with individuals following the diet being 10-20% less likely to die from heart disease, cancer, or any other cause .
- High adherence to the MD is linked to an increase in lifespan, with studies showing additional years of survival among those who closely follow the diet .
Cardiovascular Health
- The MD has been shown to reduce risk factors for cardiovascular disease, including improved lipoprotein levels, better endothelial function, reduced insulin resistance, and lower prevalence of metabolic syndrome .
- There is a significant inverse association between the MD and both systolic and diastolic blood pressure, as well as a reduction in cardiovascular events and mortality after myocardial infarction .
Cancer Prevention
- The MD has a preventive effect on cancer, attributed to its antiproliferative and pro-apoptotic properties, mainly due to components like virgin olive oil and vegetables .
Neurodegenerative Diseases
- Evidence suggests that the MD may help prevent neurodegenerative diseases such as cognitive deficits, Alzheimer's disease, and Parkinson's disease.
Telomere Maintenance and Aging
- High adherence to the MD is associated with longer leukocyte telomere length and higher telomerase activity, which are biomarkers of aging and are linked to better health status among the elderly .
Quality of Life and Healthy Aging
- The MD is positively associated with better quality of life and healthy aging, reducing the development of age-related pathologies and promoting overall well-being .

Conclusion

The Mediterranean diet is strongly associated with increased longevity and reduced mortality from various causes, including cardiovascular diseases and cancer. It also supports cardiovascular health, cancer prevention, and neuroprotection. Additionally, the MD promotes healthy aging by maintaining telomere length and enhancing overall quality of life. These findings underscore the importance of the MD as a beneficial dietary pattern for extending lifespan and improving health in older adults.
