The Claim
Higher tea intake (1–2 cups per day) is associated with a similar reduction in dementia risk and subjective cognitive decline as caffeinated coffee intake in adults followed over the long term.
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 who drink 1–2 cups of tea per day have a similar level of reduced risk for dementia and subjective cognitive decline as those who drink caffeinated coffee over the long term.
See the scientific wording
Higher tea intake (1–2 cups per day) is associated with a similar reduction in dementia risk and subjective cognitive decline as caffeinated coffee, based on long-term follow-up of over 130,000 adults, suggesting tea may share protective properties with caffeinated coffee.
Drinking tea or coffee delivers caffeine and plant compounds that enter the brain, calm overactive immune cells, and neutralize harmful molecules that damage nerve cells, which keeps memory and thinking skills strong over time.
What the research says
1 studyStudy: Coffee and Tea Intake, Dementia Risk, and Cognitive Function.
This big, long-term study found that people who drank 1–2 cups of tea a day had a lower risk of memory problems and dementia, just like those who drank the same amount of caffeinated coffee. It suggests tea and coffee might protect the brain in similar ways.
