New research shows that eating flavonoid-rich foods like tea, berries, and apples may help reduce the risk of frailty, mental decline, and physical impairment with age.
A Simple Diet Shift May Boost Aging Health
A new study published in The American Journal of Clinical Nutrition has found that foods high in flavonoids—such as black tea, berries, citrus fruits, and apples—may lower the risk of aging-related issues like frailty, poor physical function, and mental health challenges.
Flavonoids are natural compounds found in plant-based foods. According to study author Dr. Nicola Bondonno of Edith Cowan University in Australia, these antioxidants are already known to help reduce the risk of heart disease, type 2 diabetes, and dementia. This latest study suggests they may also help people stay mobile, mentally sharp, and independent as they age.
Long-Term Study of Over 85,000 Adults
The research team analyzed data from two long-running studies: the Nurses’ Health Study (NHS) and the Health Professionals Follow-Up Study (HPFS). These studies included dietary and health data from over 62,000 women and 23,000 men aged 60 and older.
Participants reported how often they ate flavonoid-rich foods like tea, apples, oranges, grapefruit, strawberries, blueberries, and even red wine. Researchers then created a “flavodiet score” to rank each person’s intake of these foods.
This score was compared with reports of physical frailty, reduced function, and poor mental health. People with the highest flavodiet scores had the lowest risk of negative aging outcomes.
Key Findings from the Study
Women with the highest intake of flavonoids had:
- 15% lower risk of frailty
- 12% lower risk of physical impairment
- 12% lower risk of poor mental health
For men, the benefits were mostly linked to better mental health. The researchers noted that the shorter tracking period for men may have affected these results.
Limitations of the Study
Despite the strong links found, experts warned that the research is observational. This means it shows a connection, not direct cause and effect.
Dr. Darshan Shah, a longevity expert, explained that other factors—like being more active—could explain the better health seen in high-flavonoid eaters. He also pointed out that the study relied on self-reported diet surveys, which can be inaccurate due to memory errors.
Why Flavonoids May Help You Age Better
Flavonoids act as antioxidants, helping the body fight inflammation and stress. These effects are believed to protect against disease and support healthy aging.
Registered dietitian Kathryn Piper said flavonoids may also boost a process called autophagy. This is the body’s way of clearing out damaged cells and making room for healthier ones. That may help keep both the body and mind in better shape as we age.
Dr. Bondonno added that flavonoids may help reduce oxidative stress, improve blood vessel health, and even preserve muscle mass. These combined effects could support multiple systems in the body as we age.
Easy Ways to Add More Flavonoids to Your Diet
Experts agree that even if more research is needed, it’s wise to eat more flavonoid-rich foods for better health in older age. Here are some simple ways to do that:
- Start your day with green or black tea
- Add berries to smoothies or yogurt
- Drink a small glass of 100% fruit juice, like orange or blueberry juice
- Snack on apples and peanut butter
- Enjoy dark chocolate (70% cocoa or higher) as an occasional treat
- Use herbs like parsley and oregano in meals
Dietitian Maggie Moon said it’s best to start these habits in midlife or earlier. “Start early and be consistent to let the benefits build up over time,” added Piper.
Adding more flavonoid-rich foods to your meals could help protect your body and brain as you age. While more studies are needed to confirm the full effects, simple steps like sipping tea or eating berries may support healthier aging in the long run.
