Resumo

A comprehensive estimation of polyphenol intake is needed to gain a better understanding of the association between polyphenol-rich food intake and the potential effects of this intake on chronic diseases. The aim of this study was to estimate the intake of polyphenols and the major dietary contributors in the population of Sao Paulo. Data were obtained from the Health Survey-Sao Paulo (ISA-Capital 2008) and were reported for 1103 adults and elderly adults. Food intake was estimated by one 24-h dietary recall (24HR). Polyphenol intake was calculated by matching food consumption data from the 24HR with the polyphenol content in foods listed in the Phenol-Explorer database. The mean total intake of polyphenols was 377.5 (SE 15.3) mg/d. The main polyphenol classes were phenolic acids (284.8 (SE 15.9) mg/d) and flavonoids (54.6 (SE 3.5) mg/d). Intakes were higher in the elderly adults than in other adults (P < 0.001) and higher in individuals with lower educational level (P = 0.01) and current smokers (P = 0.02). The main dietary contributors for total polyphenols were coffee (70.5 %), citrus fruits (4.6%) and tropical fruits (3.4 %). Coffee was the major source of polyphenols, providing 266.2 (SE 16.5) mg/d, and contributed 92.3 % of the phenolic acids and 93.1 % of the alkylmethoxyphenols. These findings will be useful for assessing the potential role on health of polyphenols and specific polyphenol-rich foods, such as coffee, and enable a comparison with people from other countries.
