100 people were a part of this "controlled" study.
Please don't be one of those people that runs around telling people this. This is nothing more than biased surveying by a weak company in attempt to create self-promoting propaganda.
Thank you @1_over_n for doing the research

When I’m not drinking coffee, I’m less forgetful and think more clearly. I’m less anxious and better in tune with my body. I also feel more myself. But I love coffee and am usually consuming it. Thank you for sharing your experience. I’ll need to try taking a break soon.
You're welcome! The taste of coffee is pretty tough to resist, I'll admit! They do make decaffeinated coffee, although I've never tried it myself.

To some extent isn't that expected? Let's face it - who would spend the money to fund a study on a substance that's been around for hundreds (thousands?) of years? Probably if you're going to spend the money to investigate it, you expect some kind of return. So sadly, all these studies end up being funded by people with an interest in a positive outcome. The bigger question to me is, does that immediately invalidate…
It depends on the ratio of studies funded vs studies published. I wouldn't be surprised if around 90-95% of special interest funded studies that aim for a p value of aren't published .
If we had even 1 honest meta-analysis for every 10 trials like this, well, we'd know more than we do now. Small trials with inconsistent/poor designs are the bane of medical science. That said, I drink dark roast so this study must be true.
Here is nice meta study of coffee and cancer risk (dna damage and cancer are probably linked). https://www.nature.com/articles/srep33711 > coffee intake was associated with reduced risk of oral, pharynx, liver, colon, prostate, endometrial cancer and melanoma and increased lung cancer risk. (Heh. Smokers drink nearly twice as much coffee as non-smokers. Smoking increases caffeine metabolism. I think this explains the…
Yeah, this is bullshit. 100 people were a part of this "controlled" study. Please don't be one of those people that runs around telling people this.

People should learn the basics of statistics before they start to have opinions.
"Funding This study has been supported by Tchibo GmbH, Hamburg, Germany." Tchibo is a German chain of coffee retailers and cafés known for its range of non-coffee products that change weekly. https://en.wikipedia.org/wiki/Tchibo Number of locations 700 shops (Germany) 300 (rest of world) They might want to make some in-store claims about Dark Roast...
Yeaaaaaaah but who else would do the study Cmon use your head here Whether its the sugar company or the coffee company, who else would do the study just so some college conspiracy theorists dont make a netflix documentary NOBODY Its okay to acknowledge the conflict of interest thats literally what the disclaimer is for, but lets not pretend like a more objective version of this study would have ever happened
Precisely, because a more objective version would have found no effect whatsoever.
Figure 2: The coffee-treated group is anomalously higher in the quantified metric BEFORE the treatment. This is entirely an artifact of stratifying the treatment vs. control group prior to wash-out. The only significant difference is between all groups and the PRE-treatment coffee group.

To your parenthetical comment: May be unrelated, but totally anecdotal, smokers tend to drink a very light roast that is easily drinkable like a folgers or maxwell house, maybe a coffee shop light roast, like a Dunkin. I don't think smokers are downing cups of Starbucks dark blend and if they are god help their stomachs.
Lighter roasts have more caffeine, because the roasting process damages the caffeine molecule.
But when I looked for a source on that one day it seems like that's a myth. There can be differences based on whether you measure by weight vs volume but that's about it. https://www.kickinghorsecoffee.com/en/blog/caffeine-myths-da...
So now I just say I like light roasts because I like to taste the coffee and not the roast.
Trader Joe's discontinued my favorite dark roast coffee (Fair Trade Organic Guatemalan) and nothing I've found has come close to the taste and cost.

Does anyone have a suggestion for me that's ~$10-$12 per pound?
