Reliable data show that the Nicoyan region of Costa Rica is a hot spot of high
longevity. A survival follow-up of 16,300 elderly Costa Ricans estimated a Nicoya
death rate ratio (DRR) for males 1990–2011 of 0.80 (0.69–0.93 CI). For a 60-yearold
Nicoyan male, the probability of becoming centenarian is seven times that of a
Japanese male, and his life expectancy is 2.2 years greater. This Nicoya advantage
does not occur in females, is independent of socio-economic conditions, disappears
in out-migrants and comes from lower cardiovascular (CV) mortality (DRR = 0.65).
Nicoyans have lower levels of biomarkers of CV risk; they are also leaner, taller
and suffer fewer disabilities. Two markers of ageing and stress—telomere length
and dehydroepiandrosterone sulphate—are also more favourable. The Nicoya diet is
prosaic and abundant in traditional foods like rice, beans and animal protein, with
low glycemic index and high fibre content.
