The Claim
Consumption of one or more cups of coffee per day is associated with a 46% lower risk of cognitive decline in individuals aged 53 and older at baseline, based on a 20-year longitudinal study of Japanese adults.
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.
People aged 53 and older who drink one or more cups of coffee per day have a 46% lower rate of cognitive decline over 20 years compared to those who drink less, according to a long-term study of Japanese adults.
See the scientific wording
Consumption of one or more cups of coffee per day is associated with a 46% lower risk of cognitive decline in individuals aged 53 and older at baseline, but not in the overall cohort, based on a 20-year longitudinal study of Japanese adults.
Coffee caffeine blocks a brain chemical that slows down nerve cell activity, which lets brain cells use energy more efficiently and reduces harmful inflammation that damages memory circuits in older adults.
What the research says
1 studyFor people 53 or older, drinking at least one cup of coffee a day was linked to a lower chance of memory or thinking problems over 20 years — but this wasn’t true for younger people in the study.
