I used to drink 6 cans a day, but then I started taking 1 caffeine capsule a day and drinking water. Hopefully normal amounts of caffeine by itself isn't also cancerous, but I guess I wouldn't be surprised.
5-hr energy drinks have 8333% the recommended dosage!! When I saw this I threw mine away, that’s a scary amount, considering the cancer link as you said.
"High amounts" is a bit of an understatement, the study is talking about more than 6 cups of coffee daily, which is going to be in the 550-600mg range. Up to about 400mg a day is safe for adults[0]. 600mg is a lot of caffeine. For context, a Bang energy drink which is on the upper end of what you can get in a single drink, is 300mg. Most "energy drinks" are around 200mg less. I'm not sure anyone is surprised by the statement "habitually drinking 3+ energy drinks a day, every day, for an extended period of time, might be bad for you."
Like 3-5 regular cups a day (not Starbucks). Then after two weeks even 1 cup became too much. Switching to a gallon of cola then didn't cause any problems.
> For healthy adults, the FDA says 400 mg a day is OK. But consuming much more than that can have dangerous, negative effects. And the milligrams add up quickly. A medium-size coffeehouse coffee can contain more than 300 mg, and most 16-ounce energy drinks contain between 160 and 240 mg of caffeine…
3-4 cups might be on the high end of the safe spectrum, depending on what your idea of a "cup" is. (For the record, 3 half-litre beer steins of coffee a day turned out to be a spectacularly bad idea, even if hearing colours was briefly entertaining.)
That Kang et al. study was 50mg/kg of caffeine administered three times a day. That would be about a hundred cups a day of coffee for my body weight. Don't they say the dose makes the poison?
I drink 12-16oz a day. I avoid drinking more than that to avoid the health risks, like kidney stones. I'm pretty sure I'm addicted to caffeine at this point, but I haven't been curious enough to test that theory.
I don't find much mental effect from it ("I need my morning coffee to function" type thing), but the act of drinking hot coffee is quite comforting.
I follow the science, 2-3 cups of coffee a day is what was found to reduce mortality so that's what I drink. The amount of caffeine in a cup of coffee actually varies significantly, 70-140 mg, but at least 3 cups is most likely still below the FDA's recommended maximum of 400mg.
And I get headaches in the morning sometimes, coffee + aspirin has been very helpful.
I drink 2-4 cups of espresso per day (that's 4-8 shots) and would periodically switch from coffee to tea with no major ill-effects, and similarly would just not drink coffee some days, again with no major ill-effects.
Studies show that moderate caffeine consumption (2-4 cups per day) has beneficial health effects. Excess consumption is linked to adverse effects. There is an optimal dose when it comes to caffeine. Building up tolerance to where you need six or more cups is where you get into trouble.
Absolutely yes. I have only a cup of coffee (or the equivalent caffeine via tea) per day and get killer headaches if I skip a day. Whether this is okay or not, I'm not sure. I usually see articles saying three or four hundred milligrams is okay, but that seems like a lot to me (that's a few cups a day depending on how you measure your cups).
My average (3 days a week ish) day includes sipping the same can of energy drink for probably 8 hours during which ill get through about 3/5 of the can. I drink water throughout the day and like the occasional acidic zest of a sip of drink, and at an emotional level makes me feel productive even if the caffiene delivery is probably on the order of 15mg per hour.
That’s a lot of caffeine - doesn’t really change the study but also makes it hard infer anything about 1 cup a day. It’s like 4-5 decent sized cups of coffee worth.
Actually it’s also beyond what the fda recommends. “ For healthy adults, the FDA has cited 400 milligrams a day—that's about four or five cups of coffee—as an amount not generally associated with dangerous, negative effects”
But going to a bit of an extreme makes sense for an early study. If they didn’t see anything with the high caffeine intake, then a low intake would be definitely no noticeable effect. With some effect seen at high doses, now further study should be done.
“ 20 young healthy non-smokers (age: 26.4 ± 4.0 years; body mass index: 22.7 ± 1.4 kg/m2; and habitual caffeine intake: 474.1 ± 107.5 mg/day) in a 10-day caffeine (150 mg × 3 times/day), a 10-day placebo (3 times/day), and a withdrawal condition (9-day caffeine followed by 1-day placebo)”
