Polyphenols

Polyphenols are a large group of plant-based micronutrients that have antioxidant properties. Some key things to know about polyphenols:

• They are found naturally in many fruits, vegetables, nuts, seeds, flowers, cereals and plant-based beverages like tea and wine. Some foods particularly high in polyphenols include apples, berries, dark chocolate, green tea, red wine, coffee, and extra virgin olive oil.
• Polyphenols act as antioxidants in the body, helping to neutralize harmful free radicals and reducing oxidative stress. This is thought to be protective against various diseases.
• Different types of polyphenols include flavonoids, stilbenes, lignans and phenolic acids. Each type has somewhat different food sources and potential health effects.
• Potential benefits linked to polyphenol intake include reducing inflammation, improving blood flow, decreasing blood pressure, enhancing immune function, and protecting against heart disease, neurodegenerative diseases, and certain cancers.
• Polyphenols may also help with weight management by increasing fat metabolism and suppressing fat cell formation.
• The amount and type of polyphenols in a food can vary widely depending on factors like ripening, processing, preparation and storage.
• To get polyphenols in your diet, eat a wide variety of whole, minimally processed plant foods like fruits, vegetables, whole grains, legumes, nuts, herbs and spices. Aim for colorful produce as the pigments often indicate polyphenol content.
