Flavonoids are a diverse group of phytonutrients found in plants, characterized by a chemical structure based on the 15-carbon flavonoid backbone. They are classified into several subclasses, including flavonoids, isoflavones, flavanones, anthocyanins, and flavonols, each contributing distinct biological properties. Flavonoids are widely distributed in fruits, vegetables, grains, legumes, stems, bark, roots, and flowers, playing roles in plant pigmentation, UV protection, and defense mechanisms.

These compounds exhibit a range of health benefits for humans, supported by extensive research. They possess antioxidant properties, neutralizing free radicals that can damage cells and contribute to chronic diseases such as cancer, cardiovascular disease, and neurodegenerative disorders. Additionally, flavonoids have been studied for their anti-inflammatory effects, potential to improve vascular function, and ability to modulate immune responses. Some subclasses, like isoflavones, have been linked to hormonal activity, particularly in phytoestrogenic effects that may influence menopausal symptoms and bone health.

Dietary sources of flavonoids include citrus fruits (flavanones), apples and onions (flavonols), berries (anthocyanins), soy products (isoflavones), and dark chocolate (flavanol). The bioavailability of flavonoids varies depending on their subclass, food matrix, and individual metabolism. While flavonoids are generally considered safe, excessive intake of certain sources—such as supplements—may pose risks, underscoring the importance of obtaining them through a balanced diet.

Further research continues to explore the therapeutic potential of flavonoids, including their role in metabolic syndrome, cognitive function, and longevity. However, more clinical trials are needed to establish definitive health claims and optimal intake levels. As part of a plant-rich diet, flavonoids contribute to overall nutritional balance and may support long-term health outcomes.
