New research suggests drinking as many as five cups of coffee a day may have some serious health benefits.

Moms everywhere, rejoice! And grab another latte. A new study says people who drink regular, moderate amounts of coffee are less likely to die from a variety of diseases like diabetes and heart disease.

A team at the Harvard University's school of public health found having up to five cups of "mommy morning juice" a day is beneficial, and even decaf can help ward off illness. To reach their conclusions, researchers looked at data collected from more than 200,000 doctors and nurses on their diet and lifestyle habits over the course of 20 years. They discovered java drinkers were less likely to die over that period versus those who abstained from coffee.

Non-smokers who drank multiple, daily cups of Joe showed even stronger health outcomes.

"The main message is that regular consumption, meaning three to five cups of coffee a day, is associated with lower risk in total mortality and mortality from several causes like diabetes, cardiovascular disease, and suicide," says Frank Hu, a study leader and professor of nutrition.

The study did not specifically address coffee drinking during pregnancy. But doctors typically advise a 12-ounce cup of coffee containing about 200 milligrams of caffeine per day is considered safe while expecting. Overindulging on lattes and cafe mochas during pregnancy can increase your risk for miscarriage.

But if you aren't pregnant: Bottoms up! No need to feel guilty for grabbing that second, or third, or even fourth cup of coffee when mama needs a little pick-me-up. In fact, you are likely doing something very good for your long-term health.
