Summary

Story summary

Italian researchers led by Dan Buettner identified Bolotana, Sardinia, as a new blue-zone candidate.
In 2024, ten of Bolotana’s 2,262 residents were centenarians, a rate ten times Sardinia’s average.
Buettner linked longevity to daily steep-street walks, a plant-based diet of beans, vegetables, wheat, olives, and strong social ties.
Researchers are testing whether Bolotana’s olive oil, rich in odd-chain fatty acids, contributes to the high life expectancy.
