Teas from across the globe are becoming more and more popular in the U.S. One relative newcomer, yerba mate, is attracting fans for its allegedly jitter-free caffeine boost and high antioxidant content. Lab research suggests some potential health benefits from drinking yerba mate, but studies of lifelong yerba mate drinkers in the tea's native South America suggest the brew increases the risk of some cancers -- a fact most marketing campaigns omit.

President Kennedy's Addison's disease, which came to light only after his election in 1960, was most likely caused by a rare autoimmune disease, according to a Navy doctor who reviewed Kennedy's medical records. The disease, autoimmune polyendocrine syndrome type 2, or APS 2, also caused Kennedy's hypothyroidism, according to a report published Tuesday in the Annals of Internal Medicine. Hard though it is to believe these days -- when a celebrity's smallest sneeze is analyzed -- Kennedy's family and advisors were able to keep his medical history virtually secret.

"The chair is out to kill us," says James Levine, an endocrinologist at the Mayo Graduate School of Medicine.

It's no secret that people drink alcohol before they turn 21. Stories about binge drinking on college campuses and alcohol-fueled high school parties are as easy to find as the Facebook photos that document them. But underage drinking isn't all fun and games. Kids who don't know their limits can drink to the point of alcohol poisoning, and those who feel invincible — as many at that age do — may underestimate the danger of getting behind the wheel. Some experts say the solution is to lower the legal drinking age to 18. More than 130 college chancellors and presidents have signed a petition initiated in 2008 in support of the idea.

Fluoride is a natural mineral with an unnatural ability to stir controversy. On the Internet, the cavity fighter is often portrayed as a grave threat to health. Various sites call it "a deadly poison" and "an invisible killer" - the sort of thing you'd want to avoid if you had any choice.
