Many people believe that longevity is the result of expensive supplements or special superfoods, but research into the so-called Blue Zones points in a different direction, according to Tiscali.
Scientists have examined regions such as Okinawa in Japan, Ikaria in Greece, Sardinia in Italy, and Costa Rica.
Although these cultures are very different, they share one important characteristic.
Diet plays a role
According to the research, many of the world's oldest people eat the same type of food almost every day.

At the same time, several studies have found a link between higher consumption of these foods and a longer lifespan.
These foods contain plant-based protein, dietary fiber, and essential minerals.
They are also rich in resistant starch, which may support beneficial gut bacteria.
Researchers believe that a healthy gut could play an important role in both overall health and the aging process.

The common denominator
Experts estimate that people living in communities with the highest life expectancy often consume around one cup of these foods each day.
Many people in Europe and the United States consume far less, which research suggests may be one factor behind differences in health outcomes.
The food group consistently found across the regions studied is legumes, including beans, lentils, chickpeas, and soybeans.
According to Tiscali, legumes are among the most affordable foods available in supermarkets, and research suggests they may be an important part of a diet associated with a long and healthy life.
