“…In contrast, high adherence to a plant-based diet is associated with lower stroke risk (17)(18)(19)(20). Differences in dietary flavonoid intake may help explain racial and regional differences in stroke, but to our knowledge, only a few previous studies compared dietary flavonoid consumption by race (21,22) and none by region in the United States.…”

“…Diet was assessed only at baseline; therefore, changes in dietary composition could not be assessed. Although there was a 10-y interval between the release of the Block98 FFQ and the end of enrollment in the REGARDS study in 2007, analysis of NHANES data over a similar time period indicate that flavonoid intake and the distribution of dietary flavonoid sources remained stable (34); therefore, the Block98 was likely able to capture flavonoid intake accurately. Although the flavonoid content of plants varies depending on cultivars, growing conditions, and storage, values used in this study were mean flavonoid values for foods, which are the most appropriate measure to use in a large epidemiologic study in which participants likely consumed various foods from various sources.…”

Background: Flavonoids are dietary polyphenolic compounds with a variety of proposed beneficial cardiovascular effects, but rigorous prospective studies that examine the association between flavonoid intake and incident coronary heart disease (CHD) in geographically and racially diverse US samples are limited. Objective: With the use of the new, expanded USDA flavonoid database, we assessed the association between total flavonoid and flavonoid subclass intakes with incident CHD in a biracial and geographically diverse cohort, as well as effect modification by age, sex, race, and region of residence. Design: Participants were 16,678 black and white men and women enrolled in the REGARDS (REasons for Geographic and Racial Differences in Stroke) study, a national prospective cohort study. All participants were without CHD at baseline, and all completed a Block98 food-frequency questionnaire. Flavonoid intakes were estimated from USDA flavonoid databases, which were recently improved to address missing values for cooked foods and to adjust for flavonoid losses due to processing. Incident CHD events were participant reported and adjudicated by experts. Quintiles of flavonoid intake were examined as predictors of incident CHD by using Cox proportional hazards regression to obtain HRs. Tests for trend used the quintile medians. Results: Over a mean 6 SD follow-up of 6.0 6 1.9 y, 589 CHD events occurred. High flavonoid intake was associated with selfidentified white race, exercise, not smoking, more education, and higher income. In models that adjusted for sociodemographic, health behavior, and dietary factors, there was an inverse association between anthocyanidin and proanthocyanidin intakes and incident CHD (HRs for quintile 5 compared with quintile 1-anthocyanidins: 0.71; 95% CI: 0.52, 0.98; P-trend = 0.04; proanthocyanidins: 0.63; 95% CI: 0.47, 0.84; P-trend = 0.02). There was no association between total flavonoid or other flavonoid subclass intakes and incident CHD. Conclusions: Reported anthocyanidin and proanthocyanidin intakes were inversely associated with incident CHD. There was no significant effect modification by age, sex, race, or region of residence.Am J Clin Nutr 2016;104:1236-44.

“…Although total flavonoid intake is usually higher in the older age groups, subjects are likely to keep their dietary habits throughout adulthood. Therefore, no significant differences have been found in the estimation of total flavonoid intake after several years of follow-up [22,41].…”

“…In America, several studies have estimated the intake of total flavonoids, especially in the US [22,[34][35][36]41], since the USDA databases were developed there [13][14][15]. In the US, the mean intake of total flavonoids varies from 250 to 400 mg/day, including proanthocyanidins and thearubigins [22,[34][35][36]41].…”

Dietary patterns and food availability differ greatly between regions and countries around the world. As a result, there is a large variability in the intake of total flavonoids and flavonoid subclasses, and subsequently in their major food sources. However, we need to be aware of certain methodological issues when we compare studies on flavonoid intake.In order to evaluate the intake of flavonoids, the different potential dietary assessment methodologies (dietary questionnaires and biomarkers) will be presented. Advantages and limitations of using of the two main food composition databases on flavonoids (US Department of Agriculture and Phenol-Explorer databases) will be discussed. The intake of total flavonoid and flavonoid subclasses in the various studies around the world will be comprehensively reviewed. The major food sources of flavonoids by region/country will be described. The main determinants of the intake of flavonoids will be explained as well.Calculating the intake of flavonoids is the first step before estimating their potential protective effects against chronic diseases and is an essential step for developing future dietary guidelines on flavonoids.

Abstract: The results of this study provide updated information on flavonoid intake and food contributors and warrant further studies on the health implications of flavonoid intake.
