Title: Dietary intake of total and citrus flavonoid of individuals with self-reported diseases.
Background: This work estimated the intake of total and citrus flavonoids by comparing groups of individuals with and without self-reported diseases, and identified the main dietary sources of flavonoids.
Methods and Findings: A cross-sectional observational study was conducted with 122 individuals of both genders, which answered questions about socialdemographic data, health status, lifestyle, diet, disease, etc., and were divided in a self-reported diseases group and a without self-reported diseases group. The intake of total and citrus flavonoids was evaluated using the 24-hour recalls and the main dietary sources of flavonoids have been identified. Citrus, onion, beans, lettuce, banana, apple, arugula and chocolate were the most important dietary sources of flavonoids. The total flavonoids average intake was 37.67 ± 40.05 mg/ day, citrus flavonoid average intake was 37.35 ± 36.78 mg/day and hesperidin, narigenin and eriodictyol intake were 28.11 ± 23.00 mg/day, 4.54 ± 4.22 mg/day and 1.30 ± 1.29 mg/day, respectively. The intake of flavonoids of the self-reported diseases group was significantly higher (p ≤ 0.05) than the without self-reported diseases group.
Conclusions: Orange, orange juice and lemon were the main flavonoids sources, responsible for the total dietary flavonoid intake. The individuals with selfreported diseases showed to be more concerned about health since they diet, consume more dietary supplements, drink less alcoholic beverages and consume more citrus and total flavonoids than the individuals without self-reported diseases (p ≤ 0.05).
