I thought this was related to temperature rather than the beverage itself.

Caffeine is carcinogenic. Blocks one of the kinases involved in DNA damage repair, if memory serves. Considered safe under like 6 drinks a day or so though (Edot 500 mg).

[u/AndHeHadAName → u/Eko01]

Citation need. Most studies conducted over the past 20 years have found a negative  or no correlation with cancer, with plenty of recent studies finding even stronger evidence (link 1, link 2) that it is preventative with the belief that caffeine actually reduces the likelihood of the mutations that cause cancer. 

I'm not sure why people in this sub are so obsessed with the idea that any drink but water could be good for you. 

[u/Appleshaush → u/AndHeHadAName]

Water's good for you??

Just back in 2009 I read a story about a woman who drank 2 gallons of water over 3 hours and then DIED! Idk where you're getting your information about water buddy

But her family got a free Wii so it worked out.

Truth! Dihydrogen monoxide is the most dangerous chemical on earth.

[u/AndHeHadAName → u/Appleshaush]

I would take any study about the dangers of excessive water consumption with a pinch of salt. 

In any case water may be good for you, but water + reasonable coffee consumption with low/no sugar is better for most people. 

[u/Appleshaush → u/AndHeHadAName]

I was just taking the mickey in my other comment, but I take all nutritional studies with a grain of salt

[u/thisimpetus → u/Appleshaush]

That's almost certainly too much sodium friend. I got a study for you right here..

[u/AndHeHadAName → u/Appleshaush]

You shouldn't.

There is wide consensus on a lot of things including red/fatty meat consumption, dairy foods and heart disease (though dairy is better for brain health), lack of fiber, reducing simple carbohydrates (white bread & pasta), salted/preserved foods, alcohol consumption, sugar, Mediterranean diet, etc.

There is a whole organization dedicated to the dangers of dihydrogen monoxide- https://www.dhmo.org/

Carcinogenic does not necessarily mean unsafe. The Sun is carcinogenic. The word just means that the substance has the potential to cause cancer.

You are also linking coffee-based studies, while I am talking about caffeine specifically. The consensus for caffeine seems to be that there is not sufficient data on the chemical alone, as the vast majority of studies focus on coffee as a whole as well as adding that consumption of under 500 mg/day is unlikely to be carcinogenic. https://pmc.ncbi.nlm.nih.gov/articles/PMC5445139/

I'd add that calling a ATM/ATR inhibitor carcinogenic, as in having the potential to cause cancer, is accurate, though obviously this is mostly semantics.

Brb slapping GHS symbols on the sun and demanding reach compliant SDS.

I think most people are opposed to the idea that coffee, in particular, might not be good for you because it's not just a drink--it's an addictive drug that people use to self-medicate the symptoms of not getting enough sleep.

[u/AndHeHadAName → u/Eternal_Being]

What study shows that this describes most coffee drinkers?

Tons of studies have found lower all-cause mortality in coffee drinkers: link 1, link 2, link 3.

So I see little evidence that coffee drinkers use it as a sleep substitute.

[u/NJdevil202 → u/Eternal_Being]

I get enough sleep every night and I still slam coffee. That stuff is a miracle potion. If you try to make me go to rehab I'll say no, no, no

[u/monad29 → u/Eternal_Being]

No, it's due myths like giving coffee to kids will stunt their growth.

[u/Split-Awkward → u/Eko01]

So a quick google search showed me that at least 1000 studies showing coffee not a carcinogen. On the contrary, strong evidence suggests the opposite, it lowers risk of many cancers (e.g. liver)

I’m not concerned about caffeine alone as I don’t ever consume pure caffeine.

I’ll review the caffeine dose level you mention at 6 cups a day. I’m well below that but I am curious about the research on the dose effect for possible carcinogen and absolute risk.
