The Amount Of Coffee Nearly 25% Of People Drink Every Day

If you're someone who just isn't yourself before your first cup of coffee in the morning, you're not alone: Most Americans enjoy at least one cup of coffee each day, and in a recent survey of Health Digest readers, 25 percent say that they typically drink two cups of coffee per day.

While coffee may not be for everyone — those who are sensitive to caffeine, for instance — for many people, a black coffee is extremely healthy. "Coffee also contains antioxidants and other active substances that may reduce internal inflammation and protect against disease," registered dietitian Diane Vizthum told Johns Hopkins University School of Medicine.

And even a single cup can be beneficial. In fact, it may come as a surprise to coffee lovers, but almost 30 percent of those surveyed actually stop at just one cup of coffee daily. Coffee may improve your longevity by reducing your risk of coronary heart disease, stroke, diabetes, and kidney disease.

There's more good news: Research has also found that coffee can offer protection against Parkinson's disease, type 2 diabetes, liver disease, and even decrease your risk of a heart attack or stroke (via the Mayo Clinic). 

For those who really love their coffee, you're not alone: 10 percent of those surveyed drink more than five cups daily. And in fact, research has shown that sipping between three and five cups per day (which accounted for roughly 25 percent of those surveyed) is actually healthy and is often linked to a decrease in chronic diseases and other health problems (via Harvard).

However, if you don't love the jittery feeling associated with one too many espressos, many of the health benefits are available even if you opt for decaf. But skip the sugar and fat-laden add-ins like syrup and whipped cream to keep your coffee health-friendly.
