     Although eating sparingly may have been less a choice than an involuntary circumstance of poverty in places like early 20th-century Calabria, decades of research have suggested that a severely restricted diet is connected to long life. Lately, however,this theory has fallen on hard scientific times. Several recent studies have undermined the link between longevity and caloricrestriction.
    In any case, Passarino was more interested in the centenarians themselves than in what they had eaten during their lifetimes. In afield historically marred by exaggerated claims and dubious entrepreneurs hawking unproven elixirs, scientists studyinglongevity have begun using powerful genomic technologies, basic molecular research, and, most importantly, data on small,genetically isolated communities of people to gain increased insight into the maladies of old age and how they might be avoided.In Calabria, Ecuador, Hawaii, and even in the Bronx, studies are turning up molecules and chemical pathways that mayultimately help everyone reach an advanced age in good, even vibrant, health.
