When I was young My Mom always said "All things in Moderation" Well too much Halloween candy really can make you sick, especially if you’ve got a fondness for licorice, according to the Food and Drug Administration. As ghosts and goblins prepare for trick-or-treating, the FDA is warning adults that eating too much of the old-fashioned favorite could land them in the hospital. Eating 2 ounces of black licorice a day for at least two weeks could cause an irregular heart rhythm or arrhythmia in adults over 40, the agency says. That’s because the candy contains glycyrrhizin, which can cause potassium levels in the body to fall. When that happens, some people experience abnormal heart rhythms, as well as high blood pressure, swelling, lethargy, and congestive heart failure. The FDA said doctors report that potassium levels are usually restored when the patient stops eating black licorice.
