Progressive population ageing in developed countries will have serious consequences for society. Different aspects of ageing can be studied from an anthropological point of view; in fact, there are marked differences in the rates of ageing among different populations and even within the same population.

Abstract
Progressive population ageing in developed countries will have serious consequences for society. Different aspects of ageing can be studied from an anthropological point of view; in fact, there are marked differences in the rates of ageing among different populations and even within the same population. Mountain communities are particularly good samples in which to evaluate the effects of various factors on ageing. We analysed the evolution of the demographic structure in the last 50 years in three mountain communities. Analysis of the demographic trends revealed a strong progressive population decline in the communities of the Western Alps starting from the beginning of the XX century, as well as a progressive increase in the number of elderly people, especially females. The quality of ageing has been emphasized in recent years and good health partly depends on a correct diet. Therefore, we examined the feeding habits in the three Alpine populations. The individuals interviewed were very careful about their diet; in fact, we did not record any nutritional deficiencies. Analysis of genealogical trees showed that the age-at-death of the ancestors of our subjects usually exceeded 75 years, demonstrating a certain inheritance of longevity.
