Possible Interaction: Antioxidants and Polyphenols

“Conclusion: Plasma antioxidant capacity can be increased by long-term ingestion of polyphenols from fruit juices or fruit–vegetable-concentrate in HIV-seropositive but not in HIV-seronegative subjects.”

“ Plant polyphenols are known to posses antioxidant and anti-inflammatory proprieties.”

“Many phytochemicals possess antioxidant and anti-inflammatory properties that may positively affect the GM, including polyphenols , carotenoids, phytosterols/phytostanols, lignans, alkaloids, glucosinolates and terpenes.”

“It is known that tea polyphenols can induce the expression of different antioxidant enzymes and hinder the DNA oxidative damage.”

“Correlation analysis showed that the contents of total polyphenols and flavonoids were significantly correlated with antioxidant and anti‐inflammatory activities.”

“While dietary fiber (such as hemicellulose), divalent minerals, and viscous and protein-rich meals are likely to cause detrimental effects on polyphenol bioaccessibility, digestible carbohydrates, dietary lipids (especially for hydrophobic polyphenols, e.g., curcumin), and additional antioxidants may enhance polyphenol availability.”

“ Plant polyphenols also induce expression of antioxidant and detoxification enzymes genes.”

“In this mini-review we critically discuss the current limitations of polyphenol research and we contend that, in addition to their putative antioxidant action , several biochemical and physiological processes might be influenced by polyphenols.”

“Enhancement of the endogenous antioxidant capacity probably also contributes to the effectiveness of the polyphenols.”

“Consistent studies showing that PPs inactivate periodontal pathogens and increase antioxidant capacity of oral fluids, suggest a preventive effect against periodontal disease with fair evidence.”
