Is Too Much Coffee Unhealthy?

"I really enjoy coffee, and I kind of crave it every day, but I'm just a little bit concerned about those health risks that come along with it."

"I heard on the news that too much coffee is unhealthy. Then another news said report that it might actually have health benefits. So, I really don't know what to think."

There's certainly lots of confusion over coffee. For years there have been warnings that it may lead to a host of health problems, ranging from dehydration to cancer. But it turns out those fears, by and large, are groundless.

It's true that caffeine in coffee can raise your heart rate and increase blood pressure temporarily. But studies show coffee does not increase the risk of heart attack or stroke. In fact, it's been associated with a slightly lower risk.

Ditto for type 2 diabetes and Parkinson's disease. According to research, coffee drinkers are less likely to develop both compared to non-drinkers. As for cancer, the news is good as well. Coffee is linked to lower odds of liver and colon cancer.

Overall, research shows java drinkers live just as long as those who abstain—and maybe even longer.

One possible reason for coffee's apparent benefit is that it's rich in antioxidants. But that doesn't make it a health drink. Higher amounts of coffee can cause jitters and stomach upset. And more than a cup or two a day has been linked to miscarriages in some research.

Bottom line: Coffee in moderation—up to a few cups a day—is likely fine for most people. But be careful of those fancy coffees with all the extra ingredients, which can add lots of extra calories. After all, you want that cup of Joe to perk you up, not weigh you down.
