Even in old age higher monounsaturated fat intake is associated with
increased survival.

Recent evidence suggested a protective role of dietary monounsaturated fatty
acids (MUFA) and polyunsaturated fatty acids (PUFA) intakes against several
chronic diseases and, therefore, an increased human longevity. After a
median follow-up of 8.5 years, we investigated the possible role of MUFA,
PUFA, and other selected food groups in protecting against all-causes
mortality in a population-based, prospective study, conducted in one of the
eight centers of the Italian Longitudinal Study on Aging (ILSA),
Casamassima, Bari, Italy. Out of 704 elderly subjects (65-84 years), 278
nondemented persons agreed to participate at the first survey (1992-1993).
During the follow-up, there were 91 deaths. A semi-quantitative food
frequency questionnaire evaluating macronutrient daily intakes were
performed at the first survey. Higher MUFA intake was associated with an
increase of survival (hazard ratio 0.81, 95% CI 0.66-0.99), a higher
unsaturated fatty acids (UFA) to SFA ratio (hazard ratio 1.20, 95% CI
0.99-1.45) increased total mortality only marginally, while no effect about
other selected food groups were found. In conclusion, in this prospective
study on older nondemented subjects with a typical Mediterranean diet, a
higher MUFA intake increased survival, while a higher UFA/SFA ratio
increased total mortality, but only marginally. PMID: 15820615
