Background: Epidemiologic studies have suggested an association
between polyphenol intake and health. These studies have been
limited to 40 flavonoid and lignan aglycones.
Objective: We estimated intakes of all known individual polyphenols
in the French cohort SUpple´mentation en VItamines et Mine´raux
AntioXydants (SU.VI.MAX) by using the recently developed
database Phenol-Explorer, which contains content values for 502
polyphenols in 452 foods.
Design: A total of 4942 men and women, who were aged 45–60 y
and who had completed at least six 24-h dietary records, participated
in this study. Foods documented in 24-h dietary records and
the Phenol-Explorer database were matched, and intakes of all individual
polyphenols were calculated.
Results: A total of 337 polyphenols were consumed by SU.VI.
MAX subjects, including 258 polyphenols consumed by at least
one-half of the population and 98 polyphenols consumed in an
amount >1 mg/d. Mean total polyphenol intake was estimated at
1193 6 510 mg/d (or 820 6 335 mg/d when expressed as aglycone
equivalents), with hydroxycinnamic acid esters and proanthocyanidins
being the most largely consumed polyphenols. These values
may have been underestimated because of insufficient data or lack
of accurate data on the content in foods for proanthocyanidins and
thearubigins. Nonalcoholic beverages and fruit were the most important
contributors to polyphenol intakes.
Conclusions: The current study provides intake data for all individual
polyphenols known to be present in the diet of a cohort. This
information will be essential to characterize the health effects of
individual phenolic compounds that differ widely in their bioavailability
and physiologic properties. The SU.VI.MAX study was registered
at clinicaltrials.gov as NCT00272428. A
