Recent research suggests that plant polyphenols—natural compounds found in fruits and vegetables—may support longevity and improve immune function. A review published in Nutrients highlights their anti-ageing properties, which can slow brain ageing, reduce inflammation, and protect against age-related diseases like Alzheimer’s and heart disease. According to registered dietitian Amy Kimberlain, polyphenols help maintain cellular health, which may extend one’s "healthspan," the years spent living in good health.
Plant polyphenols are abundant in colorful fruits and vegetables, with over 8,000 types identified. These include flavonoids, such as anthocyanins (in foods like wine and red onions), and non-flavonoids like phenolic acids (found in coffee and blueberries). Polyphenol-rich diets, like the Green-MED diet, have been linked to benefits like slower biological ageing, reduced fat, and improved brain function, according to a 2023 study.
While polyphenol supplements exist, experts recommend consuming polyphenols from whole foods, such as strawberries, walnuts, and green tea. A varied, plant-rich diet not only provides these compounds but also supports overall health through fiber and essential nutrients.
