I'm going to completely disregard this study. "What would the world look like if this study were true?"<p>53% is such a large effect size that if the study were anywhere near accurate, I'd expect to have seen many other similar studies, and other knock-on effects (nothing in the body is isolated, even dementia). But we all know that studies routinely find no or only positive health benefits associated with drinking coffee.<p>I bet this study is junk.
Title:<p>>Too much coffee can cause your brain to shrink<p>><i>cause</i><p>Conclusion from study:<p>>High coffee consumption was associated with smaller total brain volumes and increased odds of dementia.<p>><i>associated</i>
Why on earth do we measure coffee in cups? People drink more espresso and other drinks like cold brew than ever these days, just talk about caffeine in mg
There's too little information on the sampling<p>> 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.<p>The study had access to a relatively large dataset, but how many people have dementia and drink >6/day?<p>Also, for understanding the <i>effects</i> of coffee drinking on dementia the data set has to be tracked for a decent amount of time... decades? I have very strong doubts about the integrity of the data.<p>How long do you have to drink >6/day before that kicks in? obviously doing it once isn't going to cut it.
One thing I have noticed is that studies that end up with conclusions that sound like BS end up being BS studies.<p>The effect size of a 50% increase of dementia risk sounds way to high for coffee. Seems like there is a good chance of some correlated variable they are missing or a faulty assumption.
If I read the abstract correctly they found an inverse correlation between coffee consumption and brain volume, but since it was not a longitudinal study it doesn't prove that coffee is correlated to brain shrinkage?
I'm pretty sure there's a study I read that said coffee reduces the risk of dementia.<p>Here's my rule for most everything in life: everything in moderation. When I skip a day with coffee, I enjoy it a lot more the next day.
this is confusing. is it a metric cup of coffee or a 'cup of coffee' which is apparently 6 oz....<p>why use cups of coffee...do they mean the measurement or the receptacle.<p>how does one now measure their consumption? what is a Starbucks in cups?
Head: Too many web pages to fill may be associated with garbage research getting published.<p>Subhead: Journalist says "Not my fault! My editor told me 'fear sells' "
First Google result says a cup is 250 ml, is this right? I usually drink one and a half mug per day, which is about 750 ml. I
I did stop drinking coffee after 18 o clock and I'm sleeping way better.
