Understanding Flavonoids: Types and Functions in Human Health

Flavonoids are a vast family of polyphenolic compounds syntetized by plants as secondary metabolites. They serve multiple role in plant biology - attenting pollinatores, consexing against pathogens, and protecting from ultraviolet radiation - but in human dietion, they have garnered attention for their potent antioksydant and anti- estimatory contritiies.

How Flavonoids Influence Diabetes andBlood Sugar Regulation

Te relacje between dietary flavonoids ande type 2 diabetetes is supported by a growing body of epidemiological and mechanistic research. Flavonoids affect glucose homeostasis thugh several interconnecte pathways, including oksydative stres reduction, anti- efficulmatory signaling, direct modulation of glucose metiism, and emerging effects on the microbiome.

Oxidative Stress and Insulin Resistance

Chronic hyperglycemia increases production of reactivee oxygen species (ROS), which difficiir insulin signaling by activating stres- sensitiva kinase (JNK, IKKβ) that interfere with insulin receptor substrate (IRS- 1) fosylation. Flavonoids such as quercetin and kaempferol act as freedirect -radical scavengers and upregulate endoxidant enzymes like superoxide dismase, catalase, and glutathione peroxide.
