Resumen

Introduction: several indexes are used to measure the quality of nutrition in advanced ages. None of them were designed to evaluate nutrition to avoid disabilities in elderly population.Objectives: to retrieve from literature “nutrients and intakes” showing to be involved in aging, and propose a new index, considering this information, to evaluate the quality of nutrition for preventing diseases related to aging.Methods: a bibliographic review was performed, retrieving information on nutrients associated with aging. All these nutrients were incorporated into a new Healthy Aging Diet Index (HADI). Next, a cross-sectional study was carried out with two convenience samples of elderly, collecting the nutritional and dietary data, calculating different validated indexes and comparing them with HADI to validate the results.Results: forty-eight manuscripts were retrieved for full-text analysis. Associations were found between cardiovascular diseases and macronutrients,dietary fibre, sodium and vitamin D; cancer and fatty acids; diabetes and fatty acids, fibre and simple sugars; osteopenia/osteoporosis and calcium and vitamin D; sarcopenia and proteins, calcium, and vitamin D; and between cognitive impairment and fatty acids and folates. Sample 2, associated with rural areas, obtained lower indexes’ scores. The behavior of HADI is similar to the other indexes (6.24/14 and 6.10/14 in samples 1 and 2, respectively).Conclusions: the presented collection of nutrients adds useful evidence for the design of diets that allow healthy aging. The new index proposed is a tool of specific nutritional measurement in studies aimed to prevent diseases related to aging.
