The Coffee Conundrum

Coffee: it's the nectar of the gods—or at least, the caffeine dependent. Championed by the morning-challenged and hero of the mid-afternoon slump, coffee is part of the day-to-day routine for most of us. Americans alone drink an average of over 400 8-ounce cups per year. But the debate around this beloved beverage is fierce: is coffee good or bad for you? Weigh both sides of the issue before (or during) your next cup of joe.

• Pro: Antioxidants. Coffee's got plenty of these free radical-fighters, which keep your skin young.
• Con: Nutrient Deficiencies. Excessive caffeine consumption may contribute to osteoporosis, as it causes the body to excrete calcium, potassium, magnesium and iron—all nutrients essential to bone health. 
• Pro: Disease Prevention. Coffee may slow the progression of a number of diseases, from neurological disorders like Parkinson's and Alzheimer's to type 2 diabetes and some cancers.
• Con: Cardio Risks. Caffeine can elevate blood pressure and raise cholesterol, both risk factors for heart attacks.
• Pro: Painkiller. Caffeine releases B-endorphins, hormones that suppress pain. It also constricts blood vessels, leading to faster absorption of medications, which is why it's often added to pain meds.
• Con: Stress. Caffeine triggers excess production of adrenaline, your “fight or flight” hormone. When the adrenal high wears off, you might feel a drop in energy, become irritable or anxious or get a headache.
• Pro: Alertness and Endurance. The amount of caffeine in just one cup of coffee can increase energy, concentration and endurance prior to exercise.
• Con: Digestive Issues. Drinking coffee causes the stomach to secrete hydrochloric acid, which can lead to heartburn, acid reflux and IBS.

The jury may still be out, but if you're a coffee fan, just add plenty of water to your diet to counterbalance its dehydrating effects. And, like many delicious treats, moderation might be the key to living a long life full of little pleasures—like a morning mug of coffee.
