Flavonoids

Definition

Flavonoids are natural substances found in fruits, vegetables, and other plant-based foods known to have antioxidant properties that support overall health.

Scientific / Technical Definition

Flavonoids are a diverse group of phytonutrients (plant chemicals) found in almost all fruits and vegetables. They belong to a class of polyphenolic compounds and are known for their wide range of biological activities, including antioxidant, anti-inflammatory, anti-mutagenic, and anti-carcinogenic properties. Flavonoids are responsible for the vibrant colors in many plants and have been studied for their potential health benefits, particularly in reducing the risk of chronic diseases such as heart disease and cancer.

Benefits

• Act as powerful antioxidants, helping to neutralize free radicals in the body.
• May reduce the risk of heart disease by improving blood vessel function and reducing inflammation.
• Can support the immune system due to their anti-inflammatory properties.
• May have cancer-fighting properties through their ability to prevent cellular damage and inhibit tumor growth.
• Promote brain health by enhancing cognitive function and possibly reducing the risk of neurodegenerative diseases.

Examples

• Citrus fruits like oranges and lemons
• Berries such as strawberries, blueberries, and cherries
• Onions and garlic
• Tea, especially green and black varieties
• Red wine

Additional Information

• Importance: Flavonoids are important for protecting cells from oxidative stress and inflammation, which can contribute to chronic diseases. Including a variety of flavonoid-rich foods in your diet supports overall health and vitality.
