Though many refer to their java habit as an unhealthy indulgence, experts say that in moderation, a cup or two of joe a day actually has numerous health perks.
"People always talk about it as if it's a little bad for you. That's not necessarily true," says Donald Hensrud, associate professor of Preventive Medicine and Nutrition at the Mayo Clinic. "Coffee contains over 2,000 different chemical components, including cancer-fighting anti-oxidants."
Some studies suggest coffee can boost vision and heart health, says registered dietitian Elisa Zied, author of Nutrition at Your Fingertips. Research also has suggested coffee helps people with liver disease, but it has had mixed results when it comes to diabetes.
But be aware of how much caffeine you're consuming, because it varies among coffee drinks, says Mary Rosser, assistant professor of obstetrics and gynecology at Montefiore Medical Center in the Bronx, N.Y.
Loading up on cream and sugar is a bad idea, Hensrud says. A Starbucks venti 24-ounce double chocolate chip frappucino has 520 calories, 14 grams of saturated fat and 75 grams of carbohydrates. Pregnant women and people with anxiety and sleep problems should especially watch their intake, he says.
