A new study reveals that consuming flavonoid-rich foods like black tea, berries, citrus fruits, and apples may promote healthier aging by reducing the risk of frailty, physical decline, and poor mental health. The research, conducted by an international team from Edith Cowan University, Queen’s University Belfast, and Harvard T.H. Chan School of Public Health, analyzed data from over 86,000 participants over 24 years, published in the American Journal of Clinical Nutrition.
The study found that women with the highest flavonoid intake had a 15% lower risk of frailty, a 12% lower risk of impaired physical function, and a 12% lower risk of poor mental health compared to those with the lowest intakes. While men showed fewer associations, higher flavonoid consumption was still linked to better mental health outcomes.
Flavonoids, natural compounds known for their antioxidant and anti-inflammatory properties, support blood vessel health and may help maintain muscle mass, key factors in healthy aging. “Regularly consuming flavonoid-rich foods could significantly impact aging outcomes,” said Professor Aedin Cassidy, the study’s senior author.
The researchers noted that increasing flavonoid intake by just three servings per day was associated with a 6% to 11% lower risk of aging-related issues in women and a 15% lower risk of poor mental health in men.
Dr. Nicola Bondonno, an adjunct lecturer at Edith Cowan University, emphasized, “Our goal is not just longevity but ensuring people stay healthy as they age. Flavonoids are a simple dietary addition with profound potential benefits.”
The findings highlight how small dietary changes, such as incorporating more flavonoid-rich foods, could enhance quality of life and support healthier aging. Future research may explore sex-specific effects and broader populations to confirm these results.
