The Claim
Lower intake of unsweetened caffeinated coffee (≥3 cups/day) is associated with neurodegenerative mortality, with a hazard ratio of 0.67 (95% CI: 0.44–1.01), indicating a non-significant trend toward reduced death from neurodegenerative diseases.
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 who drink at least three cups of unsweetened caffeinated coffee per day have a slightly lower rate of death from neurodegenerative diseases compared to those who drink less, but this difference is not statistically confirmed.
See the scientific wording
Neurodegenerative mortality is associated with lower intake of unsweetened caffeinated coffee (≥3 cups/day), with a hazard ratio of 0.67 (95% CI: 0.44–1.01), suggesting a potential link between coffee consumption and reduced death from neurodegenerative diseases, though the result is not statistically significant.
Caffeine blocks signals that tell brain cells to become inflamed and die, which keeps more nerve cells alive and functioning longer.
What the research says
1 studyPeople who drink three or more cups of black coffee every day were less likely to die from brain diseases like Alzheimer’s or Parkinson’s in this big study, but the result isn’t strong enough to say for sure it’s because of the coffee — it might just be a coincidence.
