  • The “biochemical scavenger theory” proposes that polyphenolic substances neutralize free radicals by creating stable chemical complexes, which stop further reactions. Furthermore, some studies proved polyphenols defend against oxidative stress by creating hydrogen peroxide, which in turn helps to control immune response behaviors like cellular proliferation. 
  • By interacting with proteins that are involved in gene expression and cell communication, polyphenols suppress pro-inflammatory transcription factors, providing protection from a number of chronic illnesses caused by inflammation.
  • The cellular proliferation of polyphenols that are suspected to be anti-carcinogenic is assumed to be arrested by causing cell aging or apoptotic death of cells. Additionally, tumor cells may be specifically affected by polyphenols due to their distinct redox state.
  • In epidemiological, animal, and human investigations, anthocyanins have been linked to both the treatment and prevention of type 2 diabetes.
  • Some polyphenols have been shown to protect against neurodegenerative disorders such as Alzheimer’s, Parkinson’s, and Huntington’s.
  • Red wine was linked to a lower incidence of neurodegenerative disorders, and a type of polyphenols, epigallocatechin gallate, blocked a neurotoxin known to cause Parkinson’s-like disease.
  • According to studies, the fact that foods high in polyphenols are nutrient-dense as opposed to energy-dense, resulting in a lower calorie consumption overall, may confuse the reduced risk of obesity linked to eating foods high in polyphenols.
  • EGCG and other catechin polyphenols have been linked to antioxidant, anti-inflammatory, and anti-mutagenic properties.
  • Blueberries, which are high in anthocyanins, help to prevent weight gain by reducing inflammation and modifying obesity pathways.
  • Dietary curcumin supplementation reduced obesity and hepatic fatty acid production while increasing fatty acid oxidation.
  • The possible interactions of polyphenols with gut bacteria are an emerging topic of research in the science of polyphenols. Evidence shows that these interactions may also influence possible benefits on chronic disease risk, such as enhanced insulin sensitivity and polyphenols’ osteoprotective and hepatoprotective properties.
  • Polyphenols’ antioxidant qualities are used by food producers and processors by adding them to foods and beverages such as meats and beer so that they may be sacrificed to stop the oxidation of other molecules in the food, such as lipids, to boost shelf stability.
  • The antioxidant polyphenols in these extracts might cause meats to start serving as a dietary source of polyphenols as their potential usage spreads.
