The Claim
Moderate consumption of two to three cups of green tea per day is associated with a 44% lower risk of cognitive decline in middle-aged adults, particularly in males, based on longitudinal assessment over two decades in a Japanese cohort.
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.
Middle-aged adults who drink two to three cups of green tea daily have a 44% lower risk of cognitive decline over 20 years, with a stronger association observed in males.

Compounds in green tea enter the bloodstream, cross into the brain, and calm down harmful inflammation and damage caused by unstable molecules, which protects nerve cells from breaking down over time.
What the research says
1 studyThis study found that middle-aged Japanese men who drank 2–3 cups of green tea every day were much less likely to develop memory or thinking problems over 20 years. It’s like green tea might be helping their brains stay sharp longer.
