The Claim
Moderate coffee consumption (1–3 cups per day) is associated with a slower rate of decline in fluid intelligence and fewer errors in pairs matching tasks over a period of nearly a decade in adults aged 60–85, compared to high coffee consumption (≥4 cups per day).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults aged 60–85 who drink 1–3 cups of coffee per day show a slower decline in fluid intelligence and make fewer mistakes in memory tasks over nearly ten years than those who drink 4 or more cups per day.
See the scientific wording
Moderate coffee consumption (1–3 cups per day) is associated with a slower rate of decline in fluid intelligence and fewer errors in pairs matching tasks over nearly a decade in adults aged 60–85, compared to high consumption (≥4 cups per day), suggesting a potential benefit for specific cognitive domains in aging populations.
Caffeine from coffee blocks signals in the brain that trigger inflammation and the buildup of harmful proteins. This keeps brain cells healthier and working better, especially in tasks that require quick thinking and problem-solving as people age.
What the research says
1 studyStudy: Moderate coffee and tea consumption is associated with slower cognitive decline
People aged 60 to 85 who drank 1 to 3 cups of coffee a day tended to keep their thinking and problem-solving skills sharper over time than those who drank 4 or more cups. The more coffee they drank beyond 3 cups, the faster their brain skills seemed to decline.
