The Claim
Tea consumption is associated with a reduced risk of dementia, and this association is significantly stronger in individuals with hypertension, with a 33% lower risk for those consuming 0–1 glass per day and a 34% lower risk for those consuming more than 1 glass per day, compared to individuals without hypertension.
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 with hypertension who drink tea have a lower risk of developing dementia than those with hypertension who do not drink tea, with the lowest risk seen in those drinking up to one glass per day.
See the scientific wording
The protective association between tea consumption and reduced dementia risk is significantly stronger in individuals with hypertension, with a 33% lower risk for those consuming 0–1 glass/day and a 34% lower risk for those consuming >1 glass/day, compared to those without hypertension.
Tea contains compounds that reduce brain inflammation and improve blood flow to the brain. In people with high blood pressure, these compounds reverse damage caused by chronic high blood pressure, such as leaky blood vessels and poor nutrient delivery to brain cells. This restores normal brain function and prevents the buildup of toxic proteins that cause dementia.
What the research says
1 studyFor people with high blood pressure, drinking tea seems to help protect their brains from dementia even more than it does for people without high blood pressure — and this study found that to be true.
