Dietary Polyphenols in Metabolic and Neurodegenerative Diseases: Molecular Targets in Autophagy and Biological Effects

Polyphenols represent a group of secondary metabolites plants which have been analyzed as potent regulators multiple biological processes, including cell proliferation, apoptosis, and autophagy, among others. These natural compounds exhibit beneficial effects protection against inflammation, oxidative stress, related injuries metabolic diseases, such cardiovascular damage, obesity diabetes, neurodegeneration. This review aims to summarize the mechanisms action polyphenols in relation activation stimulation mitochondrial function antioxidant defenses, attenuation reduction may be responsible health promoting properties these compounds.
