Summary
This paper quantifies the contribution of fruit and vegetables to daily phenolic compound intake and total antioxidant capacity in the American diet, likely using national dietary intake data linked to food composition analyses. It identifies which fruit and vegetable categories are the principal sources of dietary phenolics and antioxidant activity. The findings provide a baseline for understanding population-level exposure to dietary antioxidants and their potential relevance to chronic disease risk.
UK applicability
The study is based on US dietary patterns and food consumption data, so absolute intake estimates may not transfer directly to UK populations; however, the relative contribution of specific fruit and vegetable groups to phenolic and antioxidant intake is likely broadly relevant to UK dietary assessment and public health guidance on fruit and vegetable consumption.
Key measures
Total phenolic intake (mg/day); total antioxidant capacity (TEAC or FRAP equivalents per day); contribution of individual fruit and vegetable categories to dietary antioxidant intake
Outcomes reported
The study estimated daily consumption of phenolic compounds and total antioxidant capacity derived from fruit and vegetables in the American diet, likely drawing on dietary survey data and food composition databases.
