Nutrition
Strategies
from the
World’s
Longest-Living
Cultures
BY ISABELLA HOURIHAN, APD
What if the secret to
living longer isn’t hidden
in a pill, a 昀椀tness craze,
or the latest supplement,
but on your plate?
Around the world, there
are pockets of people
who live remarkably
long, healthy lives
well into their 90s and
even past 100. These
regions, known as Blue
Zones, include Okinawa
(Japan), Sardinia (Italy),
Ikaria (Greece), Nicoya
(Costa Rica) and the
Seventh-day Adventist
community of Loma
Linda (California, USA).
Scientists, dietitians and
longevity researchers
have studied these
populations to uncover
practical dietary habits
that support not just
longer life, but better
health throughout life’s
later decades.
Plants First: The
Foundation of Longevity
One of the strongest
common threads across
centenarian populations
is a predominantly plantbased diet. In most Blue
Zones, people obtain
approximately 90–95%
of their calories from
plant foods, including
vegetables, fruits,
legumes, whole grains,
nuts and seeds.
Plant-forward diets
support longevity for
several reasons:
• High 昀椀bre intake
supports gut health,
blood sugar regulation
and cardiovascular
health.
• Antioxidants and
phytonutrients help
protect cells from agerelated damage.
• Lower chronic disease
risk, including heart
disease, type 2 diabetes
and some cancers.
In Okinawa, traditional
meals centre on sweet
potatoes, tofu and
leafy greens, while
Mediterranean regions
such as Ikaria and
Sardinia rely heavily on
vegetables, beans, herbs
and olive oil.
Beans, Whole Grains
and Healthy Fats
Staple foods in longliving cultures are
simple, affordable and
nutrient-dense:
Legumes and beans,
such as lentils, chickpeas
and black beans, provide
plant protein, iron,
昀椀bre and slow-release
carbohydrates.
Whole grains like
brown rice, barley and
sourdough bread supply
sustained energy and
gut-supporting 昀椀bre.
Healthy fats, particularly
extra-virgin olive oil,
are a cornerstone of
Mediterranean Blue
Zones and are linked
to improved heart and
metabolic health.
Importantly, these diets
are naturally low in ultraprocessed foods, re昀椀ned
sugars and industrial
seed oils, which
research links to higher
in昀氀ammation, metabolic
disease and mortality.
