Teor de polifenóis das refeições sugeridas no guia alimentar para a população brasileira

Abstract

Studies have shown that polyphenols intake is associated with a reduced risk of noncommunicable chronic diseases. This study aimed to estimate the polyphenol contents of the meal recommendations of the Food Guide for the Brazilian Population (2014). This is a quantitative and descriptive study with data collected from the photographic records of the national food guide. The food products, the preparation mode, and the amounts recommended for breakfast, lunch, and dinner patterns were addressed. The polyphenol contents of the foods and meals were estimated using the Phenol-Explorer database, which allowed determining the6 contribution of foods and polyphenol classes to the total polyphenol content. The average total polyphenol content of breakfast patterns was 242.67 ± 161.09 mg, and coffee contributed the most to this content, while the phenolic acids showed the highest contribution relevance (≥95%). The average polyphenol contents of the lunch and dinner patterns were 311.97 ± 208.15 and 337.14 ± 220.17 mg, respectively. Unlike breakfast, flavonoids were the most representative class in these meals (p<0.005). A great contribution of leguminous was observed for both lunch and dinner to the total polyphenol content. No significant difference was observed between the polyphenol contents of the different breakfast, lunch, and dinner meal patterns (p=0.71). Therefore, the inclusion of different meals throughout the day is important for the intake of different polyphenol classes. The typical foods of the national eating habit such as coffee and beans were the main contributors to the polyphenol content of the meals recommended by the national food guide, and fresh and minimally processed foods stand out as sources of polyphenols in the Brazilian diet.
