morning (or afternoon) brew? Java lovers can take heart, because a new study has just knocked another leg out from under the haters' high horse. Researchers found that moderate coffee drinking (the subjects drank four cups a day) is not linked to dehydration as is commonly thought. Researchers tested 50 men over the course of two three-day trials and found that their hydration levels stayed the same whether they drank coffee or an equal amount of water. Women were excluded from the study because their fluid levels are more variable. And the dehydration myth is not the only one worth ditching.

Coffee causes cancer. In 1981, a study came out linking coffee to pancreatic cancer stoking fears about coffee's health risks. According the American Cancer Society, that data has not held up.

Coffee is addictive. While caffeine is a stimulant and may cause psychological or physical dependence, it is not addictive in the same way opiates, cigarettes, or other health and wellbeing-threatening substances are. You'll never hear a cappuccino lover utter the words, "I flushed my whole life down the toilet, and over what? COFFEE!" Sudden withdrawal from caffeine can be unpleasant for a couple of days, but quitting gradually tends to alleviate potential side effects.
Doctors advise pregnant women to avoid coffee because the fetus metabolizes caffeine slowly and it can also trigger acid reflux. The rest of us can relax when we say, "Make mine a Grande."
