The Claim
Replacing one daily serving of sugar-sweetened beverages with coffee is associated with a 23% lower risk of all-cause dementia, and replacing one daily serving of sugar-sweetened beverages with tea is associated with a 19% lower risk of all-cause dementia, over a median follow-up of 13.45 years in adults aged 40–69, after adjusting for multiple confounders.
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.
In adults aged 40–69, replacing one daily serving of sugar-sweetened beverages with coffee is linked to a 23% lower rate of all-cause dementia, and replacing it with tea is linked to a 19% lower rate, over a median follow-up of 13.45 years.

When people stop drinking sugary drinks and drink coffee or tea instead, the caffeine and plant compounds in these drinks reduce brain inflammation, improve blood flow to the brain, and help the body use insulin better. This protects brain cells from damage and prevents the buildup of harmful proteins that cause dementia.
What the research says
1 studyThis study found that if people swap out one sugary drink a day for coffee or tea, they’re less likely to get dementia later in life—even after accounting for other health habits. It’s like trading a soda for a cup of coffee and giving your brain a little extra protection.
