A new study suggests that drinking coffee and tea in midlife may help reduce the risk of physical frailty in older age. The research followed more than 12,500 adults in Singapore for about 20 years, tracking their beverage consumption and physical health.
Participants were around 53 years old on average when the study began and about 73 by the final check-in. Researchers asked them how much coffee, black tea, and green tea they drank. They also assessed frailty using five markers: unintentional weight loss, exhaustion, weak grip strength, slow walking speed, and low physical activity.
The results showed that people who drank four or more cups of coffee a day at midlife were about 46 percent less likely to be physically frail in later life compared to those who rarely or never drank coffee. The more coffee people drank, the lower their frailty odds tended to be. One to three cups a day did not show a strong effect on its own.
Tea drinkers also saw benefits, though more modest. People who drank tea daily were about 18 percent less likely to be frail than those who barely drank it. Green tea showed a similar edge. When researchers looked at caffeine from all sources, they found that people with the highest caffeine intake were the least likely to become frail. Higher caffeine intake was linked to stronger grip strength and faster walking speed in later life.
Possible reasons for the link
The study authors suggested that caffeine may block a molecule called adenosine, which plays a role in how muscles contract and generate force. Over time, this could help muscles maintain their performance. Coffee and tea also contain polyphenols, plant compounds with antioxidant and anti-inflammatory effects. Low-grade, chronic inflammation is one factor that drives muscle loss and physical decline in older age. Regularly consuming compounds that help control inflammation may offer long-term benefits.
Physical frailty is a measurable condition tied to a higher chance of falls, hospital stays, and losing the ability to live independently. The study used a common method to assess frailty based on the five markers mentioned. Meeting several of these markers puts someone in the frail category.
What this means for coffee and tea drinkers
The research suggests that a steady coffee habit around midlife, in the range of a few cups daily, may support strength and mobility in later years. Tea drinkers also appear to benefit, though the effect is smaller. The authors noted that everyone has a different caffeine tolerance, so people should stick with an amount that works best for them.
For those looking to maximize the health benefits of coffee, choosing beans with high polyphenol content may help. Some coffee products are also tested for mold and heavy metals, which can affect purity. The study adds to a growing body of research linking coffee and tea consumption to better health outcomes in older age.
