Actually, the answer is a little of both.
It turns out that coffee has a variety of good effects. Some of them, you already know, like the short-term boost to productivity and alertness. Others, you may not know, like the fact that men who consume moderate amounts of coffee have a 30 percent lower chance of getting prostate cancer, or the fact that coffee can help lower your risk of stroke, a whole range of cancers and Alzheimer’s disease.
In women, regular, moderate coffee consumption can reduce the risk of depression, and coffee is loaded with antioxidants that provide a whole raft of health benefits.
Based on that, coffee’s a regular wonder drink, but hold on. The key is moderation, and the magic number is between 500-600 mg. That’s the maximum amount of caffeine you want to ingest each day, which puts a hard upper limit on how much coffee is good for you.
Contrary to the popular saying that there’s no such thing as too much of a good thing, in coffee’s case, there is. The more you exceed that 500-600 mg threshold, the more negative effects you will begin to see.
The good news is that based on those numbers, you can safely enjoy 6-8 cups of coffee a day without experiencing any adverse effects. That’s more than half a pot, which is a decent amount by any reckoning, although power coffee drinkers will probably need to make a few adjustments.
The main point, though, is that if you stick with that limit, then you can enjoy your coffee guilt-free!
