Flavonoid-rich foods such as black tea, berries, citrus fruits, and apples have been identified in a recent study as potential contributors to healthier aging. Conducted by researchers from Edith Cowan University, Queen’s University Belfast, and Harvard T.H. Chan School of Public Health, the study found that a diet high in flavonoids could help lower the risk of conditions associated with unhealthy aging, including frailty, impaired physical function, and poor mental health.
Dr. Nicola Bondonno, an ECU Adjunct Lecturer, emphasized the importance of not only extending lifespan but also ensuring a healthy quality of life as people age. Previous research has shown that individuals with higher flavonoid intake tend to have a longer life expectancy and a lower risk of chronic diseases such as dementia, diabetes, and heart disease. The new study further supports the idea that a diet rich in flavonoids can lead to better aging outcomes.
Analyzing data from over 60,000 women and nearly 24,000 men over a 24-year period, the researchers 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 lower intakes. While the associations were less pronounced in men, a higher flavonoid intake was still linked to a reduced risk of poor mental health.
Professor Aedin Cassidy from Queen’s University Belfast highlighted the various health benefits of flavonoids, including reducing oxidative stress, inflammation, and supporting overall vascular health. She recommended incorporating flavonoid-rich foods like berries, apples, red wine, oranges, and tea into the diet to promote healthier aging and reduce the risk of frailty, physical decline, and mental health issues.
Increasing the intake of flavonoid-rich foods by three servings a day was associated with a 6% to 11% lower risk of aging-related outcomes in females and a 15% lower risk of poor mental health in males. Professor Eric Rimm from Harvard T.H. Chan School of Public Health emphasized the potential impact of simple dietary modifications on overall quality of life and healthy aging.
Overall, the study underscores the significance of dietary choices in influencing aging outcomes and highlights the potential for improving quality of life through a diet rich in flavonoids. The findings provide valuable insights into the role of nutrition in healthy aging and offer simple strategies for promoting physical and mental well-being as individuals grow older.
