Heresy! Worthy of Exterminatus!
More correlation vs. cause and effect BS for the non-analytical. So, 5 cups is great and 6 will kill you deader than Hell. Just clickbait. Why post such nonsense?
Two in the morning and that’s it, maybe, maybe one in the afternoon ....
I could see how it would impact brain volume since caffeine is a diuretic...so less water, less sloshy sloshy in the cranium.
Must this be ‘coffee’ or would equivalent benefits/ side effects be found in taking a 200 mg caffeine pill?
Sometimes, I don’t want to drink anything, but only want the perky boost of caffeine.
Well, what size cup do they measure?
Those who drank more than six cups of coffee per day had a 53% increased risk of dementia, as well as smaller brain volume.

That explains a lot - I used to drink a quart or more of Espresso a day while fishing commercially.
“”Everything in moderation” is the key takeaway here.”
Many of us almost instinctively know this.
THIS WEEK:
COFFEE BAD!........................
“Those who drank more than six cups of coffee per day had a 53% increased risk of dementia, as well as smaller brain volume.”
correlation is not causation ... did this study control for the other gazillion potential confounding variables? ... of course not ... AND self-reported food/beverage/behavior studies are the weakest studies of them all, verging on being practically useless ... except of course for snagging taxpayer funded grants ...
Per the actual article:
High coffee consumption, brain volume and risk of dementia and stroke
ABSTRACT
Background
Coffee is a highly popular beverage worldwide, containing caffeine which is a central nervous system stimulant.
Objectives
We examined whether habitual coffee consumption is associated with differences in brain volumes or the odds of dementia or stroke.
Methods
We conducted prospective analyses of habitual coffee consumption on 398,646 UK Biobank participants (age 37–73 years), including 17,702 participants with MRI information. We examined the associations with brain volume using covariate adjusted linear regression, and with odds of dementia (4,333 incident cases) and stroke (6,181 incident cases) using logistic regression.
Results
There were inverse linear associations between habitual coffee consumption and total brain (fully adjusted β per cup −1.42, 95% CI −1.89, −0.94), grey matter (β −0.91, 95% CI −1.20, −0.62), white matter (β −0.51, 95% CI −0.83, −0.19) and hippocampal volumes (β −0.01, 95% CI −0.02, −0.003), but no evidence to support an association with white matter hyperintensity (WMH) volume (β −0.01, 95% CI −0.07, 0.05).
The association between coffee consumption and dementia was non-linear (Pnon-linearity = 0.0001), with evidence for higher odds for non-coffee and decaffeinated coffee drinkers and those drinking >6 cups/day, compared to light coffee drinkers. After full covariate adjustment, consumption of >6 cups/day was associated with 53% higher odds of dementia compared to consumption of 1–2 cups/day (fully adjusted OR 1.53, 95% CI 1.28, 1.83), with less evidence for an association with stroke (OR 1.17, 95% CI 1.00, 1.37, p = 0.055).
Conclusion
High coffee consumption was associated with smaller total brain volumes and increased odds of dementia.
My excerpt from above:
“with evidence for higher odds for non-coffee and decaffeinated coffee drinkers and those drinking >6 cups/day, compared to light coffee drinkers.”
With all these “studies,” I remain skeptical about the conclusions that are drawn. There should be no conclusions, since the “studies” ONLY show a correlation. Most of the time there is no proof of causation. But that doesn’t stop commentators from saying there is causation.
It’s quite possible that people who are already feeling the effects of dementia drink a lot of coffee because it gives them a boost, and some added mental clarity.
Not only is the “study” on shaky ground, but it’s unrealistic. Very few people drink that much coffee, but those who do, that I know, are very active high achievers.
Coffee bad, coffee good, coffee bad, coffee good, coffee bad coffee good, and that’s just the past two months. Do what you want, and you have to die of something.
