Dietary polyphenols, oxidative stress and antioxidant and anti-inflammatory effects
Hua Zhang,Rong Tsao +1 more
TL;DR: A review on the chemistry and biochemistry of dietary polyphenols, their antioxidant and anti-inflammatory activities, and the underlying molecular mechanisms of their involvement in inflammation mediated metabolic diseases are also discussed in this article.

Free radicals in biology and medicine
TL;DR: 1. Oxygen is a toxic gas - an introduction to oxygen toxicity and reactive species, and the chemistry of free radicals and related 'reactive species'
Journal ArticleDOI
Structure-antioxidant activity relationships of flavonoids and phenolic acids
TL;DR: The factors underlying the influence of the different classes of polyphenols in enhancing their resistance to oxidation are discussed and support the contention that the partition coefficients of the flavonoids as well as their rates of reaction with the relevant radicals define the antioxidant activities in the lipophilic phase.

Dietary antioxidant flavonoids and risk of coronary heart disease: the Zutphen Elderly Study.
TL;DR: Flavonoids in regularly consumed foods may reduce the risk of death from coronary heart disease in elderly men and showed an inverse relation with incidence of myocardial infarction.
Journal ArticleDOI
Flavonoids as Antioxidants
TL;DR: This review presents the current knowledge on structural aspects and in vitro antioxidant capacity of most common flavonoids as well as in vivo antioxidant activity and effects on endogenous antioxidants.
