Background
Polyphenols have been recognized for their protective role against chronic noncommunicable diseases. Despite growing international evidence, studies assessing polyphenol intake in Latin American populations remain scarce, particularly in Chile, where profound nutritional transitions have increased the consumption of ultra-processed foods and the burden of obesity and cardiovascular disease.
Objective
This study aimed to quantify dietary polyphenol intake in the Chilean adult population using a validated self-reported food frequency questionnaire.
Methods
A descriptive cross-sectional design was conducted in 521 adults aged ≥18 years, residing in different Chilean macrozones. Sociodemographic, anthropometric, and lifestyle data were collected, and polyphenol intake was estimated.
Results
The mean age of participants was 33.3 ± 10.1 years, with a predominance of women. The average daily intake of polyphenols was 1634.9 ± 1168.6 mg/d, with higher, though non-significant, consumption observed among women, rural residents, and individuals from the northern macrozone. Age-stratified analysis showed that men ≥30 years consumed significantly more polyphenols than younger men.
Conclusion
Fruits represented the main dietary source, followed by coffee and tea, while wine and cider contributed minimally.
