As people get older, a common problem is "unhealthy aging," which includes becoming physically frail, losing mobility, and facing poor mental health. Researchers from ECU and Harvard found a solution in flavonoid-rich foods like black tea, berries, and apples. Their study shows that eating more of these natural compounds lowers the risk of frailty and physical decline. The benefit is a higher quality of life, helping people stay independent, sharp, and healthy as they age.
