Dietary flavonoids are a group of plant-based chemical compounds that are responsible for the colors and flavors of various fruits, vegetables, tea, and wine. They belong to the larger class of phytochemicals called polyphenols, which have antioxidant properties.
Flavonoids can be found in a wide variety of foods such as citrus fruits, berries, apples, grapes, onions, and dark chocolate. They are thought to provide health benefits by reducing inflammation, improving blood flow, and protecting against cell damage caused by free radicals.
Incorporating a diet rich in flavonoids has been associated with a reduced risk of chronic diseases such as heart disease, cancer, and neurodegenerative disorders like Alzheimer's disease. However, more research is needed to fully understand the potential health benefits of consuming these compounds through food rather than supplements.
