Want to age healthily? A higher intake of black tea, berries, citrus fruits, and apples may help, according to global research.
Researchers from Edith Cowan University (Australia), Queen’s University Belfast (UK), and the Harvard T.H. Chan School of Public Health (US) found that foods rich in flavonoids could help lower the risk of key components associated with unhealthy ageing, including frailty, impaired physical function, and poor mental health.
“The goal of medical research is not just to help people live longer but to ensure they stay healthy for as long as possible,” said Dr Nicola Bondonno, Adjunct Lecturer at Edith Cowan University.
Previous studies have shown that individuals with higher flavonoid intake tend to live longer and are less likely to develop major chronic diseases such as dementia, diabetes, or heart disease.
“Our research shows that people who consume more flavonoids tend to age better,” Bondonno added.
The study, which analysed data from 62,743 women and 23,687 men over a span of 24 years, found that women with the highest flavonoid intake had a 15 per cent lower risk of frailty, a 12 per cent lower risk of impaired physical function, and a 12 per cent lower risk of poor mental health, compared to those with the lowest intake.
While fewer associations were observed in men, higher flavonoid intake was still linked to a lower risk of poor mental health.
“Flavonoids are well known for reducing oxidative stress and inflammation, supporting blood vessel health, and even helping to maintain skeletal muscle mass — all of which are important for preventing frailty and maintaining physical function and mental health as we age,” said Professor Aedin Cassidy from Queen’s University Belfast.
The study also showed that participants who increased their intake of flavonoid-rich foods by three servings a day had a 6 to 11 per cent lower risk across all three ageing-related outcomes in women, and a 15 per cent lower risk of poor mental health in men.
“Overall, these findings underscore the potential for simple dietary modifications to improve quality of life and support healthy ageing,” added Professor Eric Rimm from Harvard.
