TRUE OR FALSE: Coffee can cause irregular heartbeat.
Answer: TRUE. But not to worry! A slight, temporary rise in heart rate and blood pressure is common in those who are sensitive to caffeine—but the rise is comparative to normal activity like walking up stairs. That said, if you have high blood pressure, talk to your doctor about caffeine intake as some people may be more sensitive to its effects—coffee may increase risk of stroke in people in high blood pressure, so you may want to consider ditching your daily cup.
What’s the best way to green your coffee consumption?
A. Use an electric coffeemaker.
B. Use a French press.
C. Use disposable filters.
D. Make coffee at home.
Answer: B & D. Start by ditching paper cups at coffee shops and make your own coffee at home…using a French Press.

TRUE OR FALSE: Caffeine increases risk for osteoporosis..
Answer: False. Moderate amounts of caffeine–about 300 milligrams, roughly three cups of coffee–apparently cause no harm in most healthy adults. At high levels (more than 744 milligrams per day, around seven or eight cups of coffee), caffeine may increase calcium and magnesium loss in urine. But recent studies suggest it does not increase your risk for bone loss, especially if you get enough calcium. You can offset the calcium lost from drinking one cup of coffee by adding just two tablespoons of milk.
