A better study for determining whether coffee is actually good or bad would be to compare coffee drinkers against strictly water drinkers, because I would not expect that the non-coffee drinkers in this study were only drinking water.

Never ever drink coffee at night….it messes with our sleep. I learned it the hard way. And science supports this fact too.

Coffee and tea have caffeine in them which alerts the brain and prevents it from winding down to sleep.

In the future, your body, nutrition, etc will be quantified and the data should be transferred to your software. Thus, with computer software simulation, about this innumerable interaction of chemical compounds, the computer will list the positive/negative effect on many of your body parts, and your longevity.

I think there is the gap of paradigm shift between the current research and the claim of personal medicine.

Hope future development of overall technology will fill in the gap.

ps.
I drink 3-7 cups of coffee everyday. Sounds not bad, according to this research.

In other words, coffee may not be quite as bad for you as previously thought, according to one preliminary study.

What we need to know is what is good about coffee? I doubt it is the caffeine, but so many studies have found a positive benefit there is likely a causative factor worth exploring.

In my particular situation, I have an inherited congenital heart defect that causes heart rhythm abnormalities; my cardiologist does not want me consuming much (any) caffeine. I find decaf coffee to be practically undrinkable, so I don’t drink coffee even though I like it. Fortunately as long as my heart maintains its proper rhythm (which we’re controlling with drugs), my cardiac function is in about the 90th percentile, so I’m in reasonably good shape, and am probably not at a significantly elevated risk of mortality from heart failure.

However many people with heart problems (both congenital and otherwise) are not so lucky, and when they’re told by their cardiologist “No caffeine” will quit coffee, but will be subject to a significantly increased risk of mortality due to atherosclerosis or heart defects or injury. Unless the study controls for bias of this kind, it’s impossible to say whether the coffee drinking is actually *beneficial* or whether it’s simply more likely to be found amongst healthy individuals.

It does sound like it probably shows that coffee is at least not notably dangerous, at least as long as you don’t have rhythm abnormalities.

Science says no.
