Modified Mediterranean diet and survival: EPIC-elderly prospective cohort study

Area of Science:

• Gerontology
• Nutritional Epidemiology
• Public Health

Background:

• The Mediterranean diet is associated with numerous health benefits.
• Modifications were made to the traditional Mediterranean diet to enhance its applicability across diverse European populations.
• Understanding the impact of dietary patterns on longevity in older adults is crucial for public health initiatives.

Purpose of the Study:

• To investigate the association between adherence to a modified Mediterranean diet and life expectancy in elderly Europeans.
• To determine if a diet emphasizing unsaturated fats over monounsaturated fats impacts survival rates in older populations.

Main Methods:

• A multicentre, prospective cohort study involving 74,607 participants aged 60+ from nine European countries.
• Adherence to the modified Mediterranean diet was assessed using a 10-point scoring system.
• Overall mortality was analyzed using Cox regression, accounting for potential confounding variables.

Main Results:

• Increased adherence to the modified Mediterranean diet score was significantly associated with reduced overall mortality.
• A two-unit increase in the diet score corresponded to an 8% reduction in mortality risk.
• While associations varied slightly by country, no significant heterogeneity was detected, with stronger effects observed in Greece and Spain.

Conclusions:

• The modified Mediterranean diet is associated with increased survival among older European populations.
• This dietary pattern, adapted for broader European contexts, offers a promising strategy for promoting longevity in the elderly.
