Welcome to BodyTalk, where you can learn about and discuss how to care for the bodies you love. Reporter Josephine Marcotty and the Star Tribune's health team post on the latest medical research and fads, invite experts to weigh in, and share insights into what makes Minnesota the quintessentially healthy place it is.

When it comes to the body, Josephine Marcotty can talk about anything without blushing. She's been writing about health care in Minnesota for more than 10 years -- everything from birth control to stem cells. She has no formal medical training (her sister is a doctor.) But she's learned a lot on the job and really does eat five fruits and vegetables a day.
