Researchers from Edith Cowan University (Australia), Queen’s University Belfast (UK), and Harvard T.H. Chan School of Public Health (US), found that foods rich in flavonoids could help to lower the risk of key components of unhealthy ageing, including frailty, impaired physical function and poor mental health.
